Detailed Description
Examples
As shown in fig. 1 and 2, the double core battery heat exchanger, which integrates heating and cooling functions, includes a first heat exchanger block 2 and a second heat exchanger block 5.
Wherein the first heat exchanger block 2 and the second heat exchanger block 5 are both laminated coolers, each comprising a plurality of laminations 25;
all the laminations 25 of the first heat exchanger block 2 and the second heat exchanger block 5 have the same shape and are arranged in parallel to each other to be stacked into a rectangular parallelepiped extending in the thickness direction;
the first heat exchanger block 2 has a first fluid channel 3 for a heat transfer medium and a second fluid channel 4 for a cooling liquid, and is provided with a heat exchanger medium input port 12 corresponding to an input end of the first fluid channel 3, and a coolant inlet port 10 and a coolant outlet port 11 corresponding to both ends of the second fluid channel 4, respectively;
the second heat exchanger block 5 has a third fluid passage 6 for heat transfer medium and a fourth fluid passage 7 for refrigerant, and is provided with a heat transfer medium outlet 15 corresponding to the output end of the third fluid passage 6, and a refrigerant inlet 13 and a refrigerant outlet 14 corresponding to both ends of the fourth fluid passage 7, respectively;
the first heat exchanger block 2 and the second heat exchanger block 5 are fixed by a connecting plate 8;
the web 8 has the same shape as each lamination 25 and is provided with at least one connecting opening 9 for communicating the first fluid passage 3 and the third fluid passage 6;
the battery heat exchanger 1 is applied to a hybrid vehicle;
the hybrid vehicle includes an internal combustion engine 23 and an on-vehicle battery 27;
the second fluid passage 4 is connected with the cooler 22 through the coolant inlet 10, the coolant outlet 11 and the coolant circuit 21;
the cooler 22 is connected to the internal combustion engine 23 for cooling the internal combustion engine 23;
the heat exchanger medium input port 12 and the heat transfer medium outlet 15 are connected with a finished automobile heat dissipation pipeline 26;
the vehicle-mounted heat radiation pipeline 26 takes away heat generated by the vehicle-mounted battery 27 and other heating elements of the hybrid vehicle through the heat exchanger medium and inputs the heat into the heat exchanger medium input port 12.
In the present invention, all the laminations 25 of the first heat exchanger block 2 and the second heat exchanger block 5 have the same shape and the same configuration, so that the number of the same parts can be increased, thereby reducing the storage and logistics costs.
By using the same lamination, reliable assembly is possible, and manufacturing quality can be improved.
The first heat exchanger block 2 and the second heat exchanger block 5 are fixed by a connecting plate 8, and the connecting plate 8 is provided with at least one connecting opening 9 for communicating the first fluid passage 3 and the third fluid passage 6;
the first heat exchanger block 2 and the second heat exchanger block 5 are directly connected to each other via the aforementioned connection plate 8, and the connection opening 9 between the first fluid channel 3 and the third fluid channel 6 is provided in the connection plate 8 itself so that the heat exchanger medium can flow through the first heat exchanger block 2 and the second heat exchanger block 5 successively.
Furthermore, since the first heat exchanger block 2 and the second heat exchanger block 5 are fixed by the connecting plate 8, previously complicated and space-consuming and expensive connecting lines between the two separate heat exchangers and the battery to be cooled or heated can be dispensed with, in particular, so that material, installation space, weight and costs can be saved.
The present invention is applied to a hybrid vehicle including an internal combustion engine 23 and an on-vehicle battery 27, the second fluid passage 4 is connected to a cooler 22 through a coolant inlet port 10, a coolant outlet port 11, and a coolant circuit 21, and the fourth fluid passage 7 of the second heat exchanger block 5 is fed with a refrigerant through a refrigerant inlet port 13 and a refrigerant outlet port 14. In this case, the fourth fluid passage 7 of the second heat exchanger block 5 actually operates as an evaporator.
With the above structure, the required space for the temperature of the vehicle-mounted battery 27 can be significantly reduced, thereby achieving the optimum power output and associated costs for the space requirement of the vehicle-mounted battery 27, which makes an important contribution particularly to better popularization of such a hybrid vehicle.
The direct coupling of the first heat exchanger block 2 and the second heat exchanger block 5 via the connection plate 8 arranged therebetween can greatly reduce the number of interfaces required in terms of installation complexity compared to the prior art, and can better meet customer requirements in terms of manufacturing effort, structural volume and weight, and required items. In particular, the line expense required between two heat exchanger blocks is eliminated.
The laminations 25 of the first heat exchanger block 2 and the laminations 25 of the second heat exchanger block 5 are constructed identically to the various parts, thus the connection reduces warehouse and logistics costs. The first heat exchanger block 2 and the second heat exchanger block 5 are also fixed via the connecting plate 8.
The invention makes it possible to completely save on piping between two separate heat exchangers for optimal temperature control of the battery 27 compared to the prior art, since now instead of these separate piping and instead of the associated connections, only the connection plate 8 is present. Thus, the weight and variety of components, the required installation space volume, in particular the material and manufacturing costs, can be significantly reduced.
If cooling of the battery 27 is required at, for example, hot external temperatures, the flow of coolant in the coolant circuit 21 and in the second fluid channels 4 of the first heat exchanger module 2 can be stopped by closing the lines between the second fluid channels 4 and the cooler 22.
In the above case, in the second heat exchanger block 5, the heat transfer medium flowing in the heat exchanger medium circuit 28 is exclusively cooled by the refrigerant evaporated in the second heat exchanger block 5.
At relatively low external temperatures, for example during winter operation, the connection of the fourth fluid channel 7 to the refrigerating device can be closed and the line between the second fluid channel 4 and the cooler 22 can be opened, so that the waste heat generated by the internal combustion engine 2 is transferred via the coolant circuit 21 to the first heat exchanger block 2 and from there to the first fluid channel 3.
In the above case, the waste heat generated by the internal combustion engine 2 can heat the battery 27 so that it can be kept within a predetermined temperature range at cold and hot outdoor temperatures by means of the heat exchanger 1 according to the invention.
In some embodiments, an electronic expansion valve 16 is provided in the refrigeration circuit 17 between the fourth fluid passage 7 and the cold device.
The electronic expansion valve 16 has a partial constriction so as to be able to reduce the pressure of the refrigerant flowing therethrough, resulting in an increase in volume or expansion.
In the above case, the electronic expansion valve 16 is inserted into the refrigerant circuit and there reduces the pressure of the refrigerant, which normally enters the electronic expansion valve 16 in the form of a nearly boiling liquid. Here, the refrigerant undergoes a change of state, in which a portion of the refrigerant evaporates during the passage, while another portion remains in the liquid state. Then, in the fourth fluid passage 7, the stationary liquid portion of the refrigerant evaporates, and finally, the heat transfer medium flowing in the third fluid passage 6 is cooled.
By means of the electronic expansion valve 16, the refrigerant can be controlled particularly precisely, which makes it possible to obtain particularly precise temperature control for the on-board battery 27.
In certain embodiments, the refrigeration device includes a compressor 18, a condenser 19, and a throttle 20.
In certain embodiments, an electronic expansion valve 16 is disposed at the refrigerant inlet 13.
In certain embodiments, the coolant circuit 21 is provided with at least one shut-off valve 24.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
