In addition, this solution reasonably distributes energy and secondary utilizes energy for systems with different needs. This system integrates different independent systems together, which can simplify the system design, construction, operation and maintenance and other steps.

It should be noted that in this solution, the first side is the low temperature side, and the second side is the high temperature side. The temperature of the first side is lower than the temperature of the second side.

It should be noted that the first radiator 4 is a liquid cooling device, and the second radiator 5 is an air cooling device. The cooling temperature required by the liquid cooling device is lower, and the cooling temperature required by the air cooling device is higher than the cooling temperature of the liquid cooling device, and the temperature of the heat exchange medium flowing out of the liquid cooling device can still meet the cooling temperature required by the air cooling device.

It should be noted that the heat dissipation device 1 is generally arranged outdoors, and dissipates heat by means of a dry cooler and a dry cooling fan. In this embodiment, the heat dissipation device 1 uniformly dissipates heat for the first pipeline 2 and the second pipeline 3. The dry cooling fan can control the temperature of the tower below the dry cooler, and perform frequency conversion according to the temperature. Furthermore, the heat dissipation device 1 is not limited to heat dissipation by means of a dry cooler-level dry cooling fan, but can also include other heat dissipation methods, such as semiconductor heat dissipation or water cooling heat dissipation.

Furthermore, it also includes a first return water pump 9 and a second return water pump 10. The first return water pump 9 is arranged in the pipeline near the first return water end, and the second return water pump 10 is arranged in the pipeline near the second return water end. The first return water pump 9 and the second return water pump 10 are suitable for providing driving force for the flow of heat exchange medium in the pipeline.

It should be noted that the flow of the first return water pump 9 and/or the second return water pump 10 can be controlled by the terminal control device to adjust the temperature difference and pressure difference of the first return water end and/or the second return water end. Specifically, temperature sensors or pressure sensors are provided on both sides of the first return water pump 9 and/or the second return water pump 10, and the temperature sensors or pressure sensors are connected to the terminal control device. The temperature difference and pressure difference and other information on both sides of the first return water pump 9 and the second return water pump 10 are monitored by the temperature sensor or pressure sensor, and then the flow of the first return water pump 9 and the second return water pump 10 is controlled by the terminal control device. For example, if the temperature difference on both sides of the first return water pump 9 and the second return water pump 10 is large or the pressure difference is small, the terminal control device increases the flow of the first return water pump 9 and the second return water pump 10 to reduce the temperature difference on both sides or increase the pressure difference, so that the temperature difference on both sides is within the normal range, and vice versa.

It should be noted that the terminal control device can further transmit the data. The terminal control device can transmit the data to a server or a host computer to facilitate operation and maintenance management.

Furthermore, a third pipeline 11 is included, one end of which is connected to the heat dissipation device 1, and the other end is connected to the first water inlet. When the temperature in the heat dissipation device 1 is very low, there is no need to cool the heat exchange medium flowing out of the heat dissipation device 1. When it needs to be directly transported to the first radiator 4, the heat dissipation device 1 can be directly connected to the first radiator 4 through the third pipeline 11.

Furthermore, a fourth pipeline 12 is included, one end of which is connected to the first return water end and the other end is connected to the heat dissipation device 1. When the temperature of the heat exchange medium in the heat dissipation device 1 is very low, there is no need for the first pipeline 2 to cool the second pipeline 3. The first return water end is directly connected to the heat dissipation device 1 through the fourth pipeline 12, thereby reducing unnecessary steps.

Furthermore, a fifth pipeline 13 is included, one end of which is connected to the second water inlet, and the other end is connected to the heat sink 1. When the temperature of the heat exchange medium in the heat sink 1 is very low, the first pipeline 2 is not required to cool the second pipeline 3. The second water inlet is directly connected to the heat sink 1 through the fifth pipeline 13, thereby reducing unnecessary steps.

Furthermore, it also includes a refrigeration system 14, which is arranged on the pipeline between the first radiator 4 and the heat dissipation device 1, one side of the refrigeration system 14 is connected to the pipeline of the first water inlet end, and the other side is connected to the pipeline of the first water return end; one side of the refrigeration system 14 is suitable for cooling the pipeline of the first water inlet end, and the other side of the refrigeration system 14 is suitable for heating the pipeline of the first water return end. It should be noted that the refrigeration system 14 is specifically a compression refrigeration equipment, that is, the compressor 15 increases the pressure and temperature of the refrigerant vapor through compression, creating conditions for transferring the heat of the refrigerant vapor to the external environment medium. The specific compressor 15 refrigeration system 14 includes a refrigerant and a compressor 15, a condenser 16, an expansion valve and an evaporator 17. In this embodiment, the expansion valve is arranged between the condenser 16 and the evaporator 17 and is not drawn. It should be noted that the compressor 15 can be in the form of a scroll compressor 15, a magnetic suspension compressor 15, an air suspension compressor 15, a screw compressor 15, a centrifugal compressor 15, etc.

It should be noted that the compressor 15 can control the temperature of the first water inlet end by frequency conversion. Specifically, a temperature sensor is provided at the first water inlet end, and the temperature of the first water inlet end is detected and checked by the temperature sensor. If the temperature of the first water inlet end is higher than the preset temperature of the first water inlet end, the frequency of the compressor 15 needs to be increased; if the temperature of the first water inlet end is higher than the preset temperature of the first water inlet end, the frequency of the compressor 15 needs to be reduced.

Furthermore, a third water return pump 18 is provided, which is arranged on the pipeline between the refrigeration system 14 and the heat dissipation device 1, specifically, on the pipeline on the side of the first water return end.

It should be noted that on-off valves are provided on the first pipeline 2 , the second pipeline 3 , the third pipeline 11 , the fourth pipeline 12 and the fifth pipeline 13 , and switching between different pipelines is achieved by controlling the opening and closing of the on-off valves.

Working principle and process

In this embodiment, the input temperature in the heat dissipation device 1 is generally the first temperature, and the output temperature is generally the second temperature. First, the heat dissipation device 1 is connected to the first radiator 4 through the first pipeline 2. The heat exchange medium at the first temperature flows out of the heat dissipation device 1 and first passes through the refrigeration system 14. The refrigeration system 14 is suitable for cooling the heat exchange medium. In this embodiment, the refrigeration system 14 reduces the temperature of the heat exchange medium to a third temperature, so that the temperature of the first water inlet end of the first pipeline 2 is the third temperature. The heat exchange medium passes through the first radiator 4 and absorbs heat from the first radiator 4. The temperature of the heat exchange medium is increased to a fourth temperature, so that the temperature of the first return water end is the fourth temperature. Then, the heat exchange medium in the first pipeline 2 flows through the first side of the first heat exchanger 6. The heat exchange medium in the first pipeline 2 exchanges heat with the second pipeline 3 after passing through the first heat exchanger 6. Then, the temperature of the first pipeline 2 is increased from the fourth temperature to the fifth temperature. Then, the first pipeline 2 passes through the refrigeration system 14, and under the action of the refrigeration system 14, the temperature in the first pipeline 2 is increased to the sixth temperature, and then flows through the first return water pump 9 and flows back to the heat dissipation device 1. At the same time, the heat sink 1 is connected to the second radiator 5 through the second pipeline 3. The heat exchange medium in the heat sink 1 will first pass through the first heat exchanger 6 when flowing to the second radiator 5. The second pipeline 3 and the first pipeline 2 undergo heat exchange through the heat exchanger. The temperature of the heat exchange medium in the second pipeline 3 drops from the second temperature to the seventh temperature. The temperature of the second water inlet end is the seventh temperature. The heat exchange medium flows through the second radiator 5 and absorbs heat. The temperature of the second return water end is the seventh temperature, and flows back to the heat sink 1 through the second return water pump 10.

When the outdoor temperature is extremely low, such as in winter, the temperature of the heat sink 1 is generally the eighth temperature. At this time, the heat sink 1 is directly connected to the first radiator 4 through the third pipeline 11, thereby avoiding passing through the refrigeration system 14, and the heat exchange medium after passing through the first radiator 4 directly flows through the fourth pipeline 12, thereby avoiding passing through the first heat exchanger 6, reducing unnecessary processes, and the refrigeration system 14 is in a shutdown state at this time, and then the heat exchange medium flows back to the heat sink 1 through the first return water pump 9. The heat sink 1 is directly connected to the second radiator 5 through the fifth pipeline 13, thereby avoiding passing through the first heat exchanger 6, reducing unnecessary processes, thereby cooling the second radiator 5, and then the heat exchange medium flows back to the heat sink 1 through the second return water pump 10.

In this embodiment, the first temperature is 47 degrees, the second temperature is 42 degrees, the third temperature is 17 degrees, the fourth temperature is 23 degrees, the fifth temperature is 25 degrees, the sixth temperature is 47 degrees, and the seventh temperature is 29 degrees. It should be noted that the first temperature, the second temperature, the third temperature, the fourth temperature, the fifth temperature, the sixth temperature and the seventh temperature can be adjusted according to actual needs.

It should be noted that the specific temperatures of the above heat dissipation device 1, the first water inlet end, the first water return end, the second water inlet end and the second water return end are only for display data, and the specific temperatures can be adjusted or changed according to actual needs. For example, by changing the power of the heat dissipation device 1, the heat dissipation device 1 can output a heat exchange medium in the range of 0 degrees to 50 degrees. Similarly, the specific temperatures of the first water inlet end, the first water return end, the second water inlet end and the second water return end will also change synchronously with the temperature output in the heat dissipation device 1.

It should be noted that the flow of the first return water pump 9 and/or the second return water pump 10 can be controlled by the terminal control device to achieve the adjustment of the temperature difference and the pressure difference of the first return water end and/or the second return water end. Specifically, temperature sensors or pressure sensors are provided on both sides of the first return water pump 9 and/or the second return water pump 10, and the temperature sensors or pressure sensors are connected to the terminal control device. The temperature difference and pressure difference and other information on both sides of the first return water pump 9 and the second return water pump 10 are monitored by the temperature sensor or the pressure sensor, and then the flow of the first return water pump 9 and the second return water pump 10 is controlled by the terminal control device. For example, if the temperature difference on both sides of the first return water pump 9 and the second return water pump 10 is large or the pressure difference is small, the terminal control device increases the flow of the first return water pump 9 and the second return water pump 10 to reduce the temperature difference or pressure difference on both sides, so that the temperature difference on both sides is within the normal range, and vice versa.

It should be noted that the terminal control device can further transmit the data. The terminal control device can transmit the data to a server or a host computer to facilitate operation and maintenance management.

It should be noted that the compressor 15 can control the temperature of the first water inlet end by frequency conversion. Specifically, a temperature sensor is provided at the first water inlet end, and the temperature of the first water inlet end is detected and checked by the temperature sensor. If the temperature of the first water inlet end is higher than the preset temperature of the first water inlet end, the frequency of the compressor 15 needs to be increased; if the temperature of the first water inlet end is higher than the preset temperature of the first water inlet end, the frequency of the compressor 15 needs to be reduced.

Then, the first pipeline 2 passes through the refrigeration system 14, and under the action of the refrigeration system 14, the temperature in the first pipeline 2 is increased to the first temperature, and then flows through the first return water pump 9 and flows back to the heat sink 1. At the same time, the heat sink 1 is connected to the second radiator 5 through the second pipeline 3. The heat exchange medium in the heat sink 1 will first pass through the first heat exchanger 6 when flowing to the second radiator 5. The second pipeline 3 and the first pipeline 2 undergo heat exchange through the heat exchanger. The temperature of the heat exchange medium in the second pipeline 3 drops from the first temperature to the second temperature. The temperature of the second water inlet end is the second temperature. The heat exchange medium flows through the second radiator 5 and absorbs heat. The temperature of the second return water end is the fifth temperature. Subsequently, the heat exchange medium at the second return water end flows through the second heat exchanger 8 through the second return water pump 10 and releases a certain amount of heat. The heat exchange medium drops from the fifth temperature to the sixth temperature and flows back to the heat sink 1. At the same time, the heat exchange medium in the waste heat recovery pipeline 7 flows from the third return water end to the third water inlet end through the third return water pump 18, wherein the temperature of the third return water end is the seventh temperature, and the heat exchange medium passes through the second heat exchanger 8, and the waste heat recovery pipeline 7 absorbs the heat in the second pipeline 3. The temperature in the waste heat recovery pipeline 7 will rise, and the temperature of the heat exchange medium will rise from the seventh temperature to the eighth temperature, thereby realizing multiple utilization of energy and supplying heat to the user end.

The fifth temperature is 49 degrees, the sixth temperature is 48 degrees, the seventh temperature is 42 degrees, and the eighth temperature is 47 degrees. It should be noted that the first temperature, the second temperature, the third temperature, the fourth temperature, the fifth temperature, the sixth temperature, the seventh temperature, and the eighth temperature can be adjusted according to actual needs.

Working principle and process

In this embodiment, the input temperature in the heat dissipation device 1 is generally the first temperature, and the output temperature is generally the second temperature. First, the heat dissipation device 1 is connected to the first radiator 4 through the first pipeline 2. The heat exchange medium at the second temperature flows out of the heat dissipation device 1 and first passes through the refrigeration system 14. The refrigeration system 14 is suitable for cooling the heat exchange medium. In this embodiment, the refrigeration system 14 reduces the temperature of the heat exchange medium to the third temperature, so that the temperature of the first water inlet end entering the first pipeline 2 is the third temperature. The heat exchange medium passes through the first radiator 4 and absorbs heat from the first radiator 4. The temperature of the heat exchange medium is increased to the fourth temperature, so that the temperature of the first return water end is the fourth temperature. Then, the heat exchange medium in the first pipeline 2 flows through the first side of the first heat exchanger 6. The heat exchange medium in the first pipeline 2 exchanges heat with the second pipeline 3 after passing through the first heat exchanger 6. Then, the temperature of the first pipeline 2 is increased from the fourth temperature to the fifth temperature. Then, the first pipeline 2 passes through the refrigeration system 14, and under the action of the refrigeration system 14, the temperature in the first pipeline 2 is increased to the first temperature, and then flows through the first return water pump 9 and flows back to the heat dissipation device 1.

Then, the heat exchange medium will pass through the second heat exchanger 8 under the action of the second water return pump 10 and exchange heat with the waste heat recovery pipeline 7, and then pass through the first heat exchanger 6 and exchange heat in the first heat exchange pipeline. The temperature of the heat exchange medium after passing through the first heat exchanger 6 is the first temperature, and then the heat exchange medium in the second pipeline 3 flows back to the heat dissipation device 1. At the same time, the heat exchange medium in the waste heat recovery pipeline 7 flows from the third water return end to the third water inlet end through the third water return pump 18, wherein the temperature of the third water return end is the seventh temperature, the heat exchange medium passes through the second heat exchanger 8, the waste heat recovery pipeline 7 absorbs the heat in the second pipeline 3, the temperature in the waste heat recovery pipeline 7 will rise, and the temperature of the third water inlet end will rise to the eighth temperature, thereby realizing multiple utilization of energy and supplying heat to the user end requiring heat.

It should be noted that the first temperature, the second temperature, the third temperature, the fourth temperature, the fifth temperature, the sixth temperature, the seventh temperature and the eighth temperature can be adjusted according to actual needs.

It should be noted that the specific temperatures of the above heat dissipation device 1, the first water inlet end, the first water return end, the second water inlet end and the second water return end are only for display data, and the specific temperatures can be adjusted or changed according to actual needs.
