When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Referring to fig. 1, a heating system according to an embodiment of the present utility model includes a liquid inlet pipe 1, a preheating module 2 and a heating device 3. The liquid inlet pipe 1 is provided with a liquid inlet channel 101, a liquid inlet 102 and a liquid outlet 103 which are oppositely arranged. The liquid inlet channel 101 of the liquid inlet pipe 1 is used for conveying liquid into the heating device 3. When the liquid inlet pipe 1 is used for conveying liquid, the liquid enters the liquid inlet hole channel 101 of the liquid inlet pipe 1 from the liquid inlet port 102 of the liquid inlet pipe 1, then flows to the liquid outlet port 103 of the liquid inlet pipe 1, and then enters the heating device 3. The preheating module 2 is connected with the liquid inlet pipe 1. The preheating module 2 is used for heating the flowing liquid to a first preset temperature. The liquid is heated to a first predetermined temperature by the preheating module 2 during the flow from the liquid inlet pipe 1 to the heating device 3, that is, the liquid is heated while flowing to the heating device 3. The heating device 3 is connected to the liquid outlet 103 of the liquid inlet pipe 1. The heating device 3 may be used to heat the liquid heated by the preheating module 2 to a second preset temperature; or the heating device 3 can be used for heating and vaporizing the liquid heated by the preheating module 2 into steam; or the heating device 3 may be used to heat the liquid heated by the preheating module 2 to the second preset temperature, or may be used to heat and vaporize the liquid heated by the preheating module 2 into steam.

Referring to fig. 1, a heating system according to an embodiment of the present utility model includes a liquid inlet pipe 1 for conveying liquid into a heating device 3, wherein the liquid inlet pipe 1 is connected with a preheating module 2, the flowing liquid can be heated to a first preset temperature during the process of conveying the liquid into the heating device 3, and the liquid heated by the preheating module 2 is heated to a second preset temperature and/or heated and vaporized into steam by the heating device 3 after the liquid is conveyed into the heating device 3; through the mode, the liquid can be heated while the liquid is conveyed, the heating device 3 only needs to heat the preheated liquid to the second preset temperature and/or heat and gasify the preheated liquid into steam, the time required by the heating device 3 to heat the liquid to the second preset temperature and/or heat and gasify the liquid into steam can be effectively shortened, and the working efficiency is improved.

It will be appreciated that the liquid may be water or other liquids.

In some preferred embodiments, in order to enable the liquid to be transported from the liquid inlet pipe 1 into the heating device 3, a water pump 4 may be connected to the liquid inlet pipe 1, see fig. 1. The water pump 4 is used to transport liquid from the liquid inlet pipe 1 into the heating device 3.

In some preferred embodiments, the heating system may further include a temperature controller, where the temperature controller may be configured to monitor whether the preheating module 2 heats the liquid to the first preset temperature, so as to facilitate timely adjustment of the preheating module 2, ensure that the preheating module 2 may heat the liquid to the first preset temperature, and effectively ensure the preheating effect of the preheating module 2.

In some examples, referring to fig. 1, the heating system includes two thermostats, a first thermostat 5 and a second thermostat 6, respectively. Wherein, the first temperature controller 5 is used for monitoring the temperature before the liquid flows into the preheating module 2, and the second temperature controller 6 is used for monitoring the temperature when the liquid flows out of the preheating module 2, so as to monitor and control the preheating module 2 better.

In one example, referring to fig. 1, the preheating module 2 has an inlet 201 and an outlet 202 disposed opposite to each other. The first temperature controller 5 may be disposed on the liquid inlet pipe 1 near the inlet 201 of the preheating module 2, and the second temperature controller 6 may be disposed on the liquid inlet pipe 1 near the outlet 202 of the preheating module 2.

In other embodiments, the first temperature controller 5 and the second temperature controller 6 may be provided at other positions, as long as it is ensured that the temperature controllers can be used to monitor whether the preheating module 2 heats the liquid to the first preset temperature.

It will be appreciated that the heating system may also comprise one or at least three thermostats.

As an example, the thermostat may be a type K thermocouple. In other embodiments, the temperature controller may be another type of temperature controller, which is not limited herein, and therefore will not be described in detail.

In some preferred embodiments, the first preset temperature may be 20 ℃ to 60 ℃.

It is understood that the first preset temperature may be any temperature within a temperature range of 20 ℃ to 60 ℃ and may be set as required. For example, in northern China, the temperature of water is lower in winter due to lower room temperature, and the first preset temperature can be set to 20 ℃,30 ℃, 45 ℃ or 60 ℃.

In some examples, the liquid is water and the first preset temperature is 60 ℃. The water is dissolved with gases such as oxygen and nitrogen, and as the water temperature increases, the solubility of the dissolved gases in the water decreases. The amount of gas in the water does not increase rapidly when the water temperature does not exceed 60 ℃. However, when the water temperature exceeds 60 ℃, as the water temperature continues to rise, dissolved gas molecules in the water escape to form a large number of bubbles, so that the water is extruded out of the preheating module 2 by the bubbles without being effectively heated in the preheating module 2, and splash is formed. When the sprayed water and gas enter the heating device 3 connected to the outlet 202 of the preheating module 2, the pressure in the heating device 3 will be increased, which will adversely affect the heating device 3, and there will be a certain safety hazard, so that the service life of the heating device 3 will be reduced. Moreover, if the heating device 3 is used for heating and gasifying water into steam, the sprayed water and gas enter the heating device 3 connected to the outlet 202 of the preheating module 2, so that the temperature of the steam generated by the heating device 3 can not reach the required temperature, and the heating effect of the heating system is seriously affected, so that the heating system cannot be used normally. The first preset temperature is 60 ℃, so that the working efficiency of the heating system can be improved as much as possible, the time required for heating the liquid to the second preset temperature and/or heating and vaporizing the liquid into steam by the heating device 3 can be shortened as much as possible, the service life of the heating device 3 can be prolonged, the fact that the preheating module 2 cannot effectively add water to the first preset temperature can be avoided, extra pressure can not be caused for the heating device 3, adverse effects on the heating device 3 are avoided, the safety is high, and the heating effect of the heating system can be fully guaranteed.

As an alternative embodiment, the inlet pipe 1 is divided into two sections, a first section 104 and a second section 105. The first tube section 104 is arranged near the liquid inlet 102 and the second tube section 105 is arranged near the liquid outlet 103. The preheating module 2 is connected between the first tube section 104 and the second tube section 105. The preheating module 2 is provided with a heating duct 203 penetrating through the preheating module 2, and the heating duct 203 is communicated with the first pipe section 104 and the second pipe section 105. The preheating module 2 is used for heating the liquid flowing through the heating duct 203 to a first preset temperature. The liquid is directly contacted with the preheating module 2, so that the heat conduction efficiency is higher, and the heating efficiency is improved.

It will be appreciated that the configuration shown in fig. 1 is merely a schematic diagram of a heating system and is not intended to limit the specific configuration and specific length of first tube segment 104 and second tube segment 105. The first pipe section 104 refers to a pipe that communicates the liquid supply system with the preheating module 2. For example, the first pipe section 104 may be the water inlet end of the preheating module 2. For example, the first pipe segment 104 may also be the water supply's own outlet pipe 301. Likewise, the second tube section 105 refers to a tube that communicates between the preheating module 2 and the heating device 3. For example, the second pipe section 105 may be an own water inlet pipe of the heating device 3, and the preheating module 2 is directly connected to the water inlet pipe of the heating device 3. For example, the second pipe section 105 may also be the water outlet end of the preheating module 2, and the preheating module 2 may be directly connected to the heating device 3. The present application is not limited to the specific structure and specific length of the first pipe section 104 and the second pipe section 105, as long as the liquid supply system, the preheating module 2 and the heating device 3 are ensured to be communicated in sequence.

As an alternative embodiment, the heating system may further comprise a heat-retaining assembly, which may be used to retain the liquid flowing through the second pipe section 105, further ensuring the temperature of the water entering the heating device 3, reducing heat losses.

It will be appreciated that in other embodiments, the preheating module 2 may be connected to the outside of the liquid inlet pipe 1, and the preheating module 2 heats the liquid inlet pipe 1, so as to indirectly heat the liquid flowing through the liquid inlet pipe 1, that is, the preheating module 2 does not directly contact the heated liquid. For example, the liquid inlet pipe 1 can be arranged in the preheating module 2 in a penetrating way.

In some preferred embodiments, the equivalent diameter of the heating tunnel 203 is 1mm to 10mm.

In some examples, the equivalent diameter of the heating channel 203 is 1mm, the liquid may sufficiently contact the wall of the heating channel 203 in the heating channel 203, and at the same time, a vortex and a turbulent flow may be formed in the heating channel 203, which may further enhance the heat transfer effect, so that the preheating module 2 may heat the liquid more efficiently.

In some examples, the equivalent diameter of the heating duct 203 is greater than 1mm and less than or equal to 10mm, and the equivalent diameter of the heating duct 203 is greater, which effectively shortens the time required for the heating system to deliver the liquid into the heating device 3, and effectively improves the working efficiency.

In some preferred embodiments, referring to fig. 3, the preheating module 2 includes a heating body 204 and a heating body. The heating body 204 has at least one heating tunnel 203. The heating tunnel 203 penetrates the heating body 204. The heating element is connected to the heating body 204, and is used for heating the heating body 204.

As an alternative embodiment, referring to fig. 3, 14 and 15, the heating body may include a first heating member 205. The first heating element 205 is coated outside the heating body 204, and the first heating element 205 is used for heating the heating body 204 from the outside of the heating body 204, so that the heating body 204 can be effectively heated, and the heating body 204 is convenient to produce and install, simple in structure and convenient to use.

In some examples, referring to fig. 3, 14 and 15, the first heat generating member 205 may be a plating film plated by a magnetron sputtering method. The plating film can be plated outside the heating body 204 by adopting a magnetron sputtering plating process, and the high-temperature stability and the high thermal conductivity are high. Referring to fig. 14 to 18, two anchor ear structures 206 may be fixed outside the heating body 204 for electrically connecting the plating film, and each anchor ear structure 206 is respectively inserted and fixed with the tab terminal 207, so as to facilitate installation.

It is understood that the first heat generating element 205 may also be a thick film circuit. Or the first heat generating member 205 may also be a printed circuit. Or the first heating member 205 may be a resistance wire wound around the outside of the heating body 204. Alternatively, the first heating element 205 may be an electromagnetic induction coil wound around the heating body 204. Or the first heating element 205 may be other structures capable of heating, so long as the first heating element can be wrapped outside the heating body 204 to heat the heating body 204 from outside, and details thereof will not be described herein.

It can be appreciated that other ways of connecting the first heat generating element 205 may be adopted, for example, the first heat generating element 205 may also be connected through a lead 208 as shown in fig. 19 (in which the first heat generating element 205 is not shown), and the present application is not limited to the way of connecting the first heat generating element 205, and thus will not be described herein.

As an alternative embodiment, referring to fig. 3 to 6 (in which the heating duct 203 of the heating body 204 is not shown), the heating body may include a second heating member 209. The second heating element 209 is embedded in the heating body 204, and is used for heating the heating body 204 from the inside of the heating body 204.

Alternatively, the middle of the heating body 204 may be provided with a mounting hole 2041. The mounting holes 2041 are used to mount the second heat generating element 209 so as to facilitate quick and efficient mounting of the second heat generating element 209 within the heating body 204.

As an example, the mounting hole 2041 may extend in the same direction as the heating channel 203, and the second heat generating element 209 may also extend in the same direction as the heating channel 203 in the mounting hole 2041, so as to further ensure that the second heat generating element 209 may sufficiently heat the liquid flowing through the heating channel 203.

In some examples, referring to fig. 3 to 6, for making the structure simpler and controlling the production cost, the second heat generating member 209 may be one, and the second heat generating member 209 is disposed coaxially with the heating body 204.

It will be appreciated that in some embodiments, the second heat generating element 209 may be enclosed within the mounting aperture 2041, thereby avoiding contact of the second heat generating element 209 with liquid flowing through the pre-heating module 2. In other embodiments, the second heat generating element 209 may also directly contact the liquid flowing through the preheating module 2, so long as the heated liquid is not adversely affected, and the preheating module 2 is not adversely affected.

It is understood that the second heat generating element 209 may be directly connected to electricity to convert electric energy into thermal energy, for example, the second heat generating element 209 may be connected to electricity through a wire passing through the heating body 204 or the preheating module 2, which is not limited to the connection mode of the second heat generating element 209. The second heating element 209 may also generate heat under the action of the first heating element 205, so long as the second heating element 209 is ensured to safely and effectively convert electric energy into heat energy.

As an alternative embodiment, referring to fig. 3, the second heat generating element 209 may be a metal core, which is simple in structure and low in cost.

In other embodiments, to further extend the heating path of the liquid, the axis of the heating tunnel 203 may be a serpentine extending curve to provide more efficient heat exchange between the liquid and the heating body 204. As an example, the axis of the heating tunnel 203 may be wavy.

Referring to fig. 9 to 13, in some examples, the heating channels 203 are distributed in a honeycomb shape in the heating body 204, so as to further increase the heat conduction area.
