[0055] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It usually transfers heat from a fluid with a higher temperature to a fluid with a lower temperature so that both meet the requirements.
[0056] When conducting heat exchange tests on heat exchangers in traditional technology, the test device includes two independently working modules, namely, a heating module for producing high-temperature fluid and a refrigeration module for producing low-temperature fluid. However, during the test, the heat absorbed by the refrigeration module will be dissipated into the air, causing energy waste. In addition, the two independently working modules increase power consumption. Therefore, traditional test devices have the problem of energy waste.

The test device provided in the embodiment of the present application uses less energy when testing the heat exchange device.
[0058] like Figure 1 As shown, a schematic diagram of a testing device provided in an embodiment of the present application is shown. Figure 1 As shown, the testing device includes an inner circulation loop 100 and an outer circulation loop 200 .
[0059] In an embodiment of the present application, the heat exchange device 300 is arranged in the internal circulation loop 100, and the internal circulation loop 100 includes heat exchange fluids of different temperatures so that the heat exchange device 300 can exchange heat with each heat exchange fluid; the external circulation loop 200 is arranged around the periphery of the internal circulation loop, and the external circulation loop 200 includes a heat transfer medium, which is used to cool down the heat exchange fluid or heat up the heat exchange fluid.
[0060] In the embodiment of the present application, heat exchange fluids of different temperatures flow in the internal circulation loop 100. Optionally, the heat exchange fluid may be water. Optionally, the heat exchange fluid may be steam.
[0061] It can be understood that the working principle of the heat exchange device 300 is to transfer heat from a high-temperature heat exchange fluid to a low-temperature heat exchange fluid. Therefore, the internal circulation loop 100 can at least provide two heat exchange fluids of different temperatures to the heat exchange device 300. Based on this, the internal circulation loop 100 can include at least two internal circulation loops 100, thereby providing at least two heat exchange fluids of different temperatures to the heat exchange device 300.
[0062] In the embodiment of the present application, a heat transfer medium circulates in the external circulation loop 200. Optionally, the heat transfer medium may be water. Optionally, the heat transfer medium may be a refrigerant.
[0063] The heat transfer medium can cool down the heat exchange fluid or heat up the heat exchange fluid. In the embodiment of the present application, in order to reduce energy waste, the heat transfer medium cools down the heat exchange fluid, that is, absorbs the heat in the heat exchange fluid. The heat can be circulated by the heat transfer medium to heat the heat exchange fluid.
[0064] In general, the test device in the above embodiment includes an internal circulation loop and an external circulation loop, wherein the heat exchange device is arranged in the internal circulation loop, and the internal circulation loop includes heat exchange fluids of different temperatures so that the heat exchange device can perform heat exchange on each heat exchange fluid, and the external circulation loop is arranged around the periphery of the internal circulation loop, and the external circulation loop includes a heat transfer medium, and the heat transfer medium is used to cool down the heat exchange fluid or to heat up the heat exchange fluid. In this way, the heat exchange fluid for heat exchange is provided to the heat exchange device through the internal circulation loop, and the heat exchange fluid is heated or cooled by the heat transfer medium in the external circulation loop, and the heat in the heat transfer medium can be recycled, thereby avoiding the problem of energy waste caused by the need for two independently working modules in the traditional technology to provide the heat exchange device with the heat exchange fluid for heat exchange. The test device provided in the embodiment of the present application uses less energy when testing the heat exchange device.
[0065] In one embodiment, based on the above embodiment, see Figure 2 In the embodiment of the present application, the internal circulation loop 100 includes a first internal circulation loop 110 and a second internal circulation loop 120, and the first internal circulation loop 110 and the second internal circulation loop 120 are respectively used to connect to the heat exchange device 300; in addition, the test device also includes a reheat module 111 and a recooling module 121; wherein the reheat module 111 is arranged in the first internal circulation loop 110 and the external circulation loop 200, and the reheat module 111 is used to heat the first heat exchange fluid flowing in the first internal circulation loop 110 through a heat transfer medium; the recooling module 121 is arranged in the second internal circulation loop 120 and the external circulation loop 200, and the recooling module 121 is used to cool down the second heat exchange fluid flowing in the second internal circulation loop 120 through a heat transfer medium.
[0066] In an embodiment of the present application, the reheat module 111 can transfer the temperature of the heat transfer medium to the first heat exchange fluid in the first internal circulation loop 110, thereby heating the first heat exchange fluid, and the re-cooling module 121 can absorb the heat of the second heat exchange fluid in the second internal circulation loop 120 through the heat transfer medium, thereby cooling the second heat exchange fluid. Therefore, in a possible implementation, the reheat module 111 and the re-cooling module 121 can be heat exchange devices with different parameters.
[0067] In one embodiment, referring to Figure 3 A first pump body 112, a first temperature measuring module 113 and a second temperature measuring module 114 are also provided in the first internal circulation loop 110. The first pump body 112 and the first temperature measuring module 113 are respectively arranged between the first end of the heat exchange device 300 and the first end of the reheat module 111, and the second temperature measuring module 114 is arranged between the second end of the heat exchange device 300 and the second end of the reheat module 111.
[0068] Among them, the first pump body 112 is used to control the flow rate of the first heat exchange fluid; the first temperature measuring module 113 is used to measure the temperature of the first heat exchange fluid output from the first end of the heat exchange device 300; the second temperature measuring module 114 is used to measure the temperature of the first heat exchange fluid entering the second end of the heat exchange device 300.
[0069] In the embodiment of the present application, the flow rate of the first heat exchange fluid can be controlled by the first pump body 112, and the heat transfer efficiency of the first heat exchange fluid can be controlled; and by measuring the temperature of the first heat exchange fluid output from the first end of the heat exchange device 300 by the first temperature measuring module 113, and measuring the temperature of the first heat exchange fluid entering the second end of the heat exchange device 300 by the second temperature measuring module 114, it can be calculated whether the heat exchange device 300 successfully transfers the preset heat from the first heat exchange fluid to the second heat exchange fluid.
[0070] Based on the above embodiments, refer to Figure 4 A pump body and a temperature measuring module can also be set in the second internal circulation loop. Therefore, in the embodiment of the present application, the second internal circulation loop 120 also includes a second pump body 122, a third temperature measuring module 123 and a fourth temperature measuring module 124. The second pump body 122 and the third temperature measuring module 123 are respectively arranged between the first end of the heat exchange device 300 and the first end of the re-cooling module 121, and the fourth temperature measuring module 124 is arranged between the second end of the heat exchange device 300 and the second end of the re-cooling module 121.
[0071] Among them, the second pump body 122 is used to control the flow rate of the second heat exchange fluid; the third temperature measuring module 123 is used to measure the temperature of the second heat exchange fluid entering the first end of the heat exchange device 300; the fourth temperature measuring module 124 is used to measure the temperature of the second heat exchange fluid output from the second end of the heat exchange device 300.
[0072] In one embodiment, based on the above embodiment, see Figure 5 In the embodiment of the present application, a compressor 210 is also provided in the external circulation loop 200, and the compressor 210 is arranged between the second end of the recooling module 121 and the second end of the reheating module 111; wherein the compressor 210 is used to compress the heat transfer medium output from the second end of the recooling module 121 to heat the heat transfer medium.
[0073] It can be understood that after passing through the re-cooling module 121, the heat transfer medium absorbs the heat in the first heat exchange fluid and the temperature rises, but the temperature of the heat transfer medium may not be able to reach the temperature for heating the second heat exchange fluid. In view of this, in an embodiment of the present application, a compressor 210 is arranged between the second end of the re-cooling module 121 and the second end of the reheating module 111, and the compressor 210 is used to compress the heat transfer medium output from the second end of the re-cooling module 121, thereby further increasing the temperature of the heat transfer medium.
[0074] Based on the above embodiments, in the embodiments of the present application, refer to Figure 6An expansion valve 220 is also provided in the external circulation loop 200, and the expansion valve 220 is arranged between the first end of the reheat module 111 and the first end of the recooling module 121; the expansion valve 220 is used to expand the heat transfer medium output from the first end of the reheat module 111 to cool the heat transfer medium.
[0075] It can be understood that after the heat transfer medium releases heat through the reheat module 111, its temperature drops, but the temperature of the heat transfer medium may not reach the temperature for heating the first heat exchange fluid, and the temperature of the heat transfer medium may not reach the temperature for cooling the second heat exchange fluid. In view of this, in an embodiment of the present application, an expansion valve 220 is set between the first end of the reheat module 111 and the first end of the re-cooling module 121, and the expansion valve 220 is used to expand the heat transfer medium output from the first end of the reheat module 111, thereby further reducing the temperature of the heat transfer medium.
[0076] In one embodiment, based on the above embodiment, see Figure 7 In the embodiment of the present application, the test device also includes a first drive component 231, and a condensation module 230 is also provided in the external circulation loop 200, and the condensation module 230 is arranged between the compressor 210 and the second end of the reheat module 111; wherein the condensation module 230 is used to condense the heat transfer medium after the compressor 210 has been compressed; the first drive component 231 is used to change the condensation rate of the condensation module 230.
[0077] It is understandable that in order to make the heat transfer medium release heat better, so as to better heat up the first heat exchange fluid, in the embodiment of the present application, a condensation module 230 is further provided between the compressor 210 and the second end of the reheat module 111. After the heat transfer medium enters the condensation module 230, the liquid phase ratio inside is increased, the heat transfer medium releases heat better, and the heating performance of the heat transfer medium is improved. Optionally, the condensation module 230 may be a condenser, and optionally, the condensation module 230 may be a cooling pipe.
[0078] In an embodiment of the present application, the testing device also includes a first drive component 231, which is used to change the condensation rate of the condensation module 230. Optionally, the first drive component 231 can be a fan. The air blown out by the fan quickly flows through the condensation module 230, which can change the flow rate of the air around the condensation module 230, thereby speeding up or slowing down the efficiency of heat dissipation of the condensation module 230 to change the condensation rate of the condensation module 230; optionally, the first drive component 231 can also be a sprayer for spraying cooling medium.
[0079] Accordingly, refer to Figure 8In one embodiment, the testing device further includes a second driving component 241, and an evaporation module 240 is further provided in the external circulation loop 220, and the evaporation module 240 is provided between the expansion valve 220 and the first end of the re-cooling mold 121; wherein the evaporation module 240 is used to evaporate the heat transfer medium after the expansion treatment of the expansion valve 220, and the second driving component 241 is used to change the evaporation efficiency of the evaporation module 240.
[0080] It is understandable that in order to make the heat transfer medium absorb heat better, so as to better cool the second heat exchange fluid, in the embodiment of the present application, an evaporation module 240 is further provided between the expansion valve 220 and the first end of the re-cooling mold 121. After the heat transfer medium enters the evaporation module 240, the proportion of the internal gas phase increases, the heat transfer medium absorbs heat better, and the cooling performance of the heat transfer medium is improved. Optionally, the evaporation module 240 may be an evaporator, and optionally, the condensation module 230 may be an evaporating dish.
[0081] In an embodiment of the present application, the testing device also includes a second drive component 241, which is used to change the evaporation rate of the evaporation module 240. Optionally, the second drive component 241 can be a fan, and the air blown out by the fan quickly flows through the evaporation module 240, which can change the flow rate of the air around the evaporation module 240, thereby speeding up or slowing down the heat dissipation efficiency of the evaporation module 240 to change the evaporation rate of the evaporation module 240; optionally, the second drive component 241 can also be a sprayer for spraying cooling medium.
[0082] Based on the above embodiments, refer to Fig. 9 A pressure measuring module 250 and a fifth temperature measuring module 260 are also provided in the external circulation loop 200. The pressure measuring module 250 and the fifth temperature measuring module 260 are sequentially arranged between the second end of the re-cooling module 121 and the compressor 210; wherein the pressure measuring module 250 is used to measure the pressure of the heat transfer medium, and the fifth temperature measuring module 260 is used to measure the temperature of the heat transfer medium.
[0083] It can be understood that in order to better control the operation of the compressor 210, the expansion valve 220, the condensing module 230, the first drive component 231 and the second drive component 240, a pressure measuring module 250 is set to measure the pressure of the heat transfer medium, and a fifth temperature measuring module 260 is set to measure the temperature of the heat transfer medium. Through the pressure value and the temperature value, the working power of the compressor 210, the opening and closing angle of the expansion valve 220, and the working power of the first drive component 231 and the second drive component 241 can be adjusted accordingly, thereby controlling the state of the heat transfer medium.
[0084] In one embodiment, see Fig.10, a testing system is provided, which includes a heat exchange device 300 and a testing device as in any of the above embodiments, wherein the testing device is connected to the heat exchange device.
[0085] The specific process and beneficial effects of the test device for providing a heated first heat exchange fluid and a cooled second heat exchange fluid to the heat exchange device can be found in the above-mentioned embodiment of the test device, which will not be described in detail here.
