[0042] Embodiment one

[0043] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding method are fast production speed, high efficiency, automatic operation, various colors and shapes, and accurate product size. The product is easy to update, can form complex parts, and is suitable for mass production and complex product molding fields. At a certain temperature, the completely melted plastic material is stirred by a screw, injected into the mold cavity under high pressure, and after cooling and solidification, the molded product is obtained. This method is one of the important processing methods, suitable for batch production of complex shaped parts, such as the production of plastic coolant flow channel plate 1 of thermal management integrated module.

[0044] The present embodiment provides a thermal management integrated module coolant flow channel plate to solve the problems of high production cost and complex processing technology of the coolant flow channel plate on the integrated module.

[0045] Specifically, as shown in Figures 1 to 2 The plastic coolant flow channel plate 1 is an injection molded element, and the plastic coolant flow channel plate 1 comprises a first pipe 11, at least two reinforcing plates 12 and at least two fixing members 13, the first pipe 11 is arranged through the at least two reinforcing plates 12, and the at least two reinforcing plates 12 are arranged along the axial direction (Z direction in the figure) of the first pipe 11; at least two groups of fixing assemblies, the fixing assembly comprises two fixing members 13, the two fixing members 13 are respectively located on both sides of the first pipe 11 in the first radial direction (X direction in the figure), and the two sides of the reinforcing plate 12 are respectively connected with the corresponding one of the fixing members 13, and the at least two groups of fixing assemblies are arranged along the second radial direction (Y direction in the figure) of the first pipe 11. Figure 1 Figure 1 Figure 1 ​​The plastic refrigerant flow channel plate 1 is produced by injection molding, which improves the dimensional accuracy of the plastic refrigerant flow channel plate 1. The first pipe 11, the reinforcing plate 12, and the fixing member 13 are produced by integral injection molding, which greatly simplifies the production process of the plastic refrigerant flow channel plate 1 and greatly reduces the production cost of the plastic refrigerant flow channel plate 1. In addition, the at least two reinforcing plates 12 are connected with the at least two groups of fixing assemblies to form a grid-shaped reinforcing structure. The grid-shaped reinforcing structure improves the support effect on the pipe wall of the first pipe 11, so that the first pipe 11 is not prone to warping deformation during injection molding, thereby improving the structural strength of the first pipe 11. The grid-shaped reinforcing structure also plays a role of tightly clamping the pipe wall of the first pipe 11, preventing the first pipe 11 from bursting due to the pressure of the refrigerant, and further improving the pressure-bearing capacity of the first pipe 11, so that the plastic refrigerant flow channel plate 1 can be compatible with more types of refrigerants.

[0046] It should be noted that in the present embodiment, the at least two groups of fixing assemblies are arranged along the second radial direction of the first pipe 11, and the second radial direction of the first pipe 11 is perpendicular to the first radial direction of the first pipe 11.

Increasing the connection position of the grid-shaped reinforcing structure and the first pipe 11 makes the support effect on the pipe wall of the first pipe 11 more obvious, so that the grid-shaped reinforcing structure has a good inhibitory effect on the deformation of the first pipe 11 during production, thereby reducing the warping deformation of the first pipe 11 during injection molding and further improving the structural strength of the first pipe 11.

[0048] In the present embodiment, the reinforcing plate 12 is perpendicular to the axial direction of the first pipe 11. In other embodiments, the reinforcing plate 12 can be not perpendicular to the axial direction of the first pipe 11.

By adding the fixing strip 17 and connecting it with the reinforcing plate 12, the strength of the grid-shaped reinforcing structure is enhanced, so that the supporting force and the clamping force of the grid-shaped reinforcing structure on the first pipe 11 are further enhanced, thereby improving the strength and pressure-bearing capacity of the first pipe 11, and making the plastic refrigerant flow channel plate 1 compatible with more types of refrigerants. In addition, by connecting the fixing strip 17 with the first pipe 11, the clamping force of the grid-shaped reinforcing structure on the first pipe 11 is enhanced, thereby further enhancing the strength of the first pipe 11.

[0050] Further, the plastic refrigerant flow channel plate 1 further comprises a fixing plate 18, and each of the reinforcing plates 12 is connected with the fixing plate 18 on the other side in the second radial direction, thereby further enhancing the strength of the grid-shaped reinforcing structure, so that the structural strength of the first pipe 11 is further enhanced.

The thickness of the pipe wall of the first pipes 11 and the second pipes 16 is uniform, so as to improve the anti-shrinkage effect. In the embodiment, the thickness of the pipe wall of the first pipes 11 and the second pipes 16 is 3.5 mm. In other embodiments, the thickness of the pipe wall of the first pipes 11 and the second pipes 16 is 3.4 mm or 3.6 mm.

[0056] Optionally, the production material of the plastic refrigerant flow channel plate 1 is selected as the plastic containing 30%-50% glass fiber, so as to reduce the production cost of the plastic refrigerant flow channel plate 1 and the weight of the plastic refrigerant flow channel plate 1 due to the characteristics of high temperature resistance, low price and small density.

[0074] Example Five

[0075] This embodiment provides a thermal management integrated module, and the differences between this embodiment and example one will be mainly described below, and the same parts will not be described again.

[0076] Specifically, as shown in Figure 8As shown, the heat management integrated module includes the compressor 2, the condenser 3, the liquid storage tank 4, the seventh control valve 77, the air supplementing heat exchanger 6, the evaporator 5, and the heat management integrated module plastic refrigerant flow channel plate 1 described above. The compressor 2, the condenser 3, the liquid storage tank 4, the air supplementing heat exchanger 6, and the evaporator 5 are integrated on the plastic refrigerant flow channel plate 1. The plastic refrigerant flow channel plate 1 is provided with an eleventh flow channel, a twelfth flow channel, a thirteenth flow channel, a fourteenth flow channel, a fifteenth flow channel, and a sixteenth flow channel. The outlet of the condenser 3 is in communication with the inlet of the liquid storage tank 4 through the eleventh flow channel. The outlet of the liquid storage tank 4 is in communication with the first inlet of the air supplementing heat exchanger 6 through the twelfth flow channel. The first outlet of the air supplementing heat exchanger 6 is in communication with the inlet of the evaporator 5 through the thirteenth flow channel. The second outlet of the air supplementing heat exchanger 6 is in communication with the inlet of the compressor 2 through the sixteenth flow channel. The outlet of the evaporator 5 is in communication with the inlet of the compressor 2 through the fourteenth flow channel. The outlet of the compressor 2 is in communication with the inlet of the condenser 3 through the fifteenth flow channel. The inlet of the seventh control valve 77 is in communication with the first outlet of the air supplementing heat exchanger 6. The outlet of the seventh control valve 77 is in communication with the second inlet of the air supplementing heat exchanger 6. The eleventh flow channel, the twelfth flow channel, the thirteenth flow channel, the fourteenth flow channel, the fifteenth flow channel, and the sixteenth flow channel are not in communication with each other. This realizes the circulation of refrigerant in the heat management integrated module. By integrating the above-mentioned low-cost plastic refrigerant flow channel plate 1 in the heat management integrated module, the production cost of the heat management integrated module is reduced. Furthermore, the eleventh flow channel, the twelfth flow channel, the thirteenth flow channel, the fourteenth flow channel, the fifteenth flow channel, and the sixteenth flow channel are six of the four first pipes 11 described above. Therefore, the eleventh flow channel, the twelfth flow channel, the thirteenth flow channel, the fourteenth flow channel, the fifteenth flow channel, and the sixteenth flow channel have high pressure-bearing capacity, so that the heat management integrated module can be applied to refrigerants with different pressures, thereby improving the universality of the heat management integrated module. In this embodiment, the seventh control valve 77 is an electronic expansion valve. In other embodiments, the seventh control valve 77 is a throttling valve.

[0077] Further, the heat management integrated module further includes a sixth control valve 76. The thirteenth flow channel is in communication with the inlet of the evaporator 5 through the sixth control valve 76. The sixth control valve 76 can adjust the flow rate of refrigerant entering the evaporator 5. In this embodiment, the sixth control valve 76 is an electronic expansion valve. In other embodiments, the sixth control valve 76 is a throttling valve.

[0078] When the compressor 2 works, the refrigerant is discharged from the exhaust port of the compressor 2, enters the condenser 3 through the fifteenth flow channel, and exchanges heat with the cooling liquid in the condenser 3. The refrigerant after heat exchange flows out of the condenser 3, enters the liquid tank 4 through the eleventh flow channel, and the liquid refrigerant flows out of the liquid tank 4, passes through the twelfth flow channel, enters the air supplementing heat exchanger 6 through the first inlet of the air supplementing heat exchanger 6, and is divided into two ways from the first outlet of the air supplementing heat exchanger 6. One way flows into the sixth control valve 76 through the thirteenth flow channel, and the gas-liquid mixed refrigerant passing through the sixth control valve 76 enters the evaporator 5, and exchanges heat with the cooling liquid in the evaporator 5. The gaseous refrigerant after heat exchange flows out of the evaporator 5, enters the compressor 2 through the fourteenth flow channel, and the compressor 2 works to compress the low-pressure gaseous refrigerant into high-pressure gaseous refrigerant, and then is discharged from the exhaust port, that is, a large cycle is completed. The other way from the first outlet of the air supplementing heat exchanger 6 passes through the seventh control valve 77, enters the air supplementing heat exchanger 6 again through the second inlet of the air supplementing heat exchanger 6, exchanges heat with the refrigerant in the air supplementing heat exchanger 6, and then the refrigerant flowing out of the second outlet of the air supplementing heat exchanger 6 enters the compressor 2 through the sixteenth flow channel. The compressor 2 works to compress the gaseous refrigerant into high-pressure gas, and then is discharged from the exhaust port, that is, a small cycle is completed, and finally the optimal thermal management target is achieved.
