[0048] Reference Figure 8 and Fig. 9 The fin heat exchanger unit module of the utility model is a module to be tested with standardized and unitized external dimensions. For ease of understanding, an example is given: it is actually necessary to test the first fin heat exchanger to be tested and the second fin heat exchanger to be tested separately, and the first fin heat exchanger to be tested and the second fin heat exchanger to be tested only have the inner diameter of the coil different. First, produce the first fin heat exchanger sample to be tested and the second fin heat exchanger sample to be tested with the same external dimensions (length, width, height), and then test the samples of different fin heat exchangers. Although the actual heat exchange area of ​​each sample is different, when the external volume of the samples is the same, the heat exchange area per unit area of ​​each sample can still be calculated, which is convenient for subsequent calculations.

[0049] In this embodiment, the fin heat exchanger unit module has multiple layers of coils, each layer of coils has a water inlet end and a water outlet end, the multiple layers of water inlet ends are connected through a first manifold 101, and the multiple layers of water outlet ends are connected through a second manifold 102.

[0050] First embodiment

[0051] Reference Figure 1 and Figure 2 The first embodiment of the utility model discloses a detection system for a fin heat exchanger unit module, comprising: an energy generator 1, a detection chamber 2, an energy storage device 3 and a measuring component. The energy generator 1 is used to provide a heat medium fluid to the detection chamber 2. Generally, gas is used as the heat medium fluid in the industry, and the gas is heated and blown toward the fin heat exchanger unit module to be tested. A accommodating cavity is provided in the detection chamber 2, and the accommodating cavity is used to place the fin heat exchanger unit module 100. The accommodating cavity has a heat medium inlet 25 and a heat medium outlet 26. The heat medium inlet 25 is connected to the energy generator 1, and the heat medium outlet 26 is connected to the outside. The energy accumulator 3 has a first chamber 32 and a second chamber 33. The first chamber 32 is connected to the liquid inlet of the fin heat exchanger unit module 100 and is used to input the refrigerant fluid into the liquid inlet of the fin heat exchanger unit module 100. The second chamber 33 is connected to the liquid outlet of the fin heat exchanger unit module 100 and is used to receive and store the refrigerant fluid from the liquid outlet of the fin heat exchanger unit module 100. Generally, pure water is used as the refrigerant fluid in the industry. The temperature of the refrigerant fluid is lower than the temperature of the heat medium fluid, forming a temperature difference. The heat medium temperature must be higher than the refrigerant temperature, but when the natural temperature of the heat medium is greater than the refrigerant temperature, the electric heating function of the thermal energy generator is not turned on.

[0052] The measuring component is used to measure the average flow rate and inlet and outlet temperatures of the gas in the detection chamber 2 , and the measuring component is also used to measure the average flow rate and inlet and outlet temperatures in the fin heat exchanger unit module 100 .

[0053] Specifically, the measuring component further includes a plurality of temperature sensors, a plurality of flow rate sensors and a plurality of flow sensors. The plurality of temperature sensors are respectively used to measure the inlet temperature of the heat medium inlet 25 of the detection chamber 2, the outlet temperature of the heat medium outlet 26 of the detection chamber 2, the inlet temperature of the liquid inlet of the fin heat exchanger unit module 100 and the outlet temperature of the liquid outlet of the fin heat exchanger unit module 100.

[0054] The multiple flow rate sensors are respectively used to measure the gas flow rate of the heat medium inlet 25 of the detection chamber 2, the gas flow rate of the heat medium outlet 26 of the detection chamber 2, the liquid flow rate of the liquid inlet of the fin heat exchanger unit module 100, and the liquid flow rate of the liquid outlet of the fin heat exchanger unit module 100.

[0055] The multiple flow sensors are respectively used to measure the gas flow of the heat medium inlet 25 of the detection chamber 2, the gas flow of the heat medium outlet 26 of the detection chamber 2, the liquid flow of the liquid inlet of the fin heat exchanger unit module 100, and the liquid flow of the liquid outlet of the fin heat exchanger unit module 100.

[0056] In this embodiment, the temperature sensor is used to measure the temperature of the heat medium inlet 25 and the heat medium outlet 26 of the detection chamber 2, that is, the temperature t / 1 of the hot fluid before the heat exchange and the temperature t1 after the heat exchange can be known. Similarly, the temperature sensor is also used to measure the temperature t2 of the liquid inlet and the temperature t / 2 of the liquid outlet of the refrigerant fluid, that is, the temperature before the heat exchange and the temperature after the heat exchange can be known. The average heat transfer temperature difference Δtm can be calculated based on the four parameters t1, t2, t / 2, and t / 1. The heat transfer amount of the hot fluid can be calculated based on the average speed of the gas flow in the detection chamber 2, the gas's own parameters and other data. The heat transfer amount of the cold fluid can be calculated based on the average flow rate of the refrigerant fluid in the fin heat exchanger unit module 100, the refrigerant fluid's own parameters and other data, and then the heat exchange efficiency of the fin heat exchanger unit module 100 can be calculated.

[0057] Of course, in other embodiments, other sensors may be installed to measure other data.

[0058] In this embodiment, the energy generator 1 has a heat medium inlet 11, a heat medium outlet 12, an electric heating component and a conveying component. The conveying component is arranged between the heat medium inlet 11 and the heat medium outlet 12. The conveying component is used to convey the gas from the heat medium inlet 11 to the heat medium outlet 12. The conveying component in this embodiment is a fan. The electric heating component is used to heat the gas in the energy generator 1 to a preset temperature. When the heat medium fluid is other media, the conveying component will also be replaced with a device that is more suitable for conveying the heat medium fluid. The heat medium temperature must be higher than the refrigerant temperature, but when the natural temperature of the heat medium is higher than the refrigerant temperature, the electric heating component of the energy generator 1 may not be turned on.

[0059] Reference Figure 3 , Figure 4 and Figure 5In this embodiment, the detection chamber 2 includes a work station 24, a first shell 21 and a second shell 23, the first shell 21 and the second shell 23 are detachably connected, wherein the first shell 21 is provided with an inner cavity 22 opening toward the second shell 23, so that after the first shell 21 and the second shell 23 are connected, the inner cavity 22 constitutes the accommodating cavity, the first shell 21 in this embodiment is in a cover shape, the first shell tightly covers the second shell 22, a groove is provided on one side wall of the second shell, the fin heat exchanger unit module 100 is placed into the groove from top to bottom, and the groove also extends from top to bottom, so that the water inlet end and the water outlet end of the coil can slide along the groove, so that the coil will not be interfered by the second shell into the inner cavity.

[0060] In other words, in order to place the fin heat exchanger unit module from top to bottom into the inner cavity, the groove provided on the side wall of the second shell serves as a clearance groove. When the fin heat exchanger unit module enters the inner cavity, the end of the coil close to the first manifold and the end of the coil close to the second manifold enter the groove and move downward along the groove until the fin heat exchanger unit module reaches the preset position. The work station 24 is fixed in the accommodating cavity, and the fin heat exchanger unit module 100 is placed on the work station. The heat medium inlet 25 and the heat medium outlet 26 are arranged on opposite sides of the first shell 21.

[0061] In this embodiment, the first shell 21 and the second shell 23 are detachably connected to facilitate the disassembly of the fin heat exchanger to inspect other fin heat exchanger unit modules 100. Since the external dimensions of each fin heat exchanger unit module 100 are the same, it is only necessary to disassemble the first shell 21 and the second shell 23 and then take out the fin heat exchanger from the inspection chamber 2, which is convenient and quick.

[0062] In this embodiment, the detection chamber 2 further includes heat insulation cotton, which is filled in the gap between the fin heat exchanger unit module 100 and the inner wall of the accommodating cavity. The heat insulation cotton fills the gap between the fin heat exchanger and the inner wall of the detection chamber 2, so that the heat exchange is concentrated near the fin heat exchanger, reducing the heat from the inner wall of the detection chamber 2 to the outside.

[0063] The outer wall of the detection chamber 2 in this embodiment is also made of heat-insulating material.

[0064] Reference Figure 2In this embodiment, the fin heat exchanger unit module detection system further includes a first air pipe, a second air pipe and a third air pipe, and the third air pipe has an air inlet end and an air outlet end. One end of the first air pipe is connected to the heat medium outlet 12, and the other end of the first air pipe is connected to the heat medium inlet 25 of the detection chamber 2. One end of the second air pipe is connected to the heat medium outlet 26 of the detection chamber 2, and the other end of the second air pipe is connected to the air inlet end of the third air pipe. The air outlet end of the third air pipe is bent upward to facilitate the direct upward discharge of hot air. If the air outlet end is bent, the hot gas will still flow upward.

[0065] In this embodiment, the cross-section of the first air pipe gradually expands from the energy storage device 3 to the detection chamber 2 to make the gas flow from the center of the first air pipe to the periphery of the detection chamber 2, so that the gas can flow from all parts of the fin heat exchanger, and the cross-section of the second air pipe gradually decreases from the detection chamber 2 to the third air pipe to smoothly guide the gas into the third air pipe.

[0066] Reference Figure 6 and Figure 7 In this embodiment, the energy storage device 3 includes a return pipe 31, a throttle valve 34, a first storage chamber and a second storage chamber, wherein the first storage chamber is provided with the first chamber 32, and the second storage chamber is provided with the second chamber 33. In this embodiment, the first storage chamber and the second storage chamber are adjacently arranged to form a whole, wherein the outer walls of the first storage chamber and the second storage chamber are both made of heat-insulating material.

[0067] One end of the return pipe 31 is connected to the first chamber 32, and the other end is connected to the second chamber 33. In this embodiment, the second chamber 33 is higher than the first chamber 32. The throttle valve 34 is arranged on the return pipe 31, and the throttle valve 34 is used to control the opening and closing of the return pipe 31.

[0068] After the refrigerant fluid enters the second chamber 33 from the fin heat exchanger, the temperature of the refrigerant fluid is relatively high, so it is placed in the second chamber 33 for a period of time. After the temperature of the refrigerant fluid in the second chamber 33 drops, the throttle valve 34 is opened to allow the refrigerant fluid to flow into the first chamber 32 under its gravity to achieve reciprocating use.

[0069] In this embodiment, the fin heat exchanger unit module detection system further includes a water pump, a water inlet valve, a water outlet valve, a water outlet pipe and a water inlet pipe, one end of the water outlet pipe is connected to the first chamber 32, and the other end of the water outlet pipe is connected to the liquid inlet of the fin heat exchanger unit module 100. One end of the water inlet pipe is connected to the second chamber 33, and the other end of the water inlet pipe is connected to the liquid outlet of the fin heat exchanger unit module 100. The water inlet valve is arranged on the water inlet pipe to control the on-off of the water inlet pipe; the water outlet valve is arranged on the water outlet pipe to control the on-off of the water outlet pipe. The water pump is arranged between the water inlet pipe and the second chamber 33 or between the water outlet pipe and the first chamber 32.

[0070] The water pump provides power for the flow of the refrigerant fluid. The low-temperature refrigerant fluid flows from the first chamber 32 of the energy storage device 3 into the fin heat exchanger unit module 100 , and the heated refrigerant fluid flows from the fin heat exchanger unit module 100 into the second chamber 33 .

[0071] The refrigerant fluid in this embodiment can be water, brine, ethylene glycol, amine refrigerants, Freon refrigerants, etc.

[0072] Second embodiment

[0073] The difference between this embodiment and the first embodiment is that the first storage chamber and the second storage chamber in this embodiment are separated, or even independent, and the inner walls of the first storage chamber and the second storage chamber are both made of heat-insulating materials.

[0074] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
