Description

Technical Field

[0001] The utility model belongs to an automobile power battery cooling system, in particular to an automobile power battery cooling device. Background Art

[0002] The current automotive battery cooling device is located outside the cab, above the vehicle frame, and adopts a horizontal structure that is long in the Y direction (left and right) and short in the Z direction (up and down). This greatly occupies the platform space above the vehicle frame and limits the layout of the vehicle. Currently, a single battery cooler is limited by the current structure and cannot be expanded to a higher power, which affects the battery life. Therefore, a new structure is needed. Summary of the invention

[0003] The purpose of the utility model is to provide a high-power vertical battery chiller assembly, which can use a smaller platform space and higher power capacity to meet the needs of battery cooling, break the barriers of vehicle layout, and improve battery life.

[0004] To achieve the above purpose, the technical solution of the utility model is:

[0005] A high-power vertical battery chiller assembly includes a condenser, a water pump, a compressor, a fan, and a cooler. The compressor, condenser, liquid reservoir, and cooler are connected through air-conditioning pipelines, and the water pump, cooler, and battery are connected through hoses. The characteristics are as follows: the fan is fixed to the fan fixing plate by bolts; the condenser is arranged vertically, connected to the condenser fixing bracket, and then fixed to the fan fixing plate by bolts; the compressor adopts a vertical layout and is connected to the fixing bracket by bolts; the water pump is fixed to the lower base plate by nuts and is placed on the left side of the lower half of the condenser.

[0006] There are two refrigerators, which are fixed side by side on the left side of the lower half of the condenser.

[0007] The beneficial effects of the utility model are:

[0008] The utility model arranges the condenser, water pump, compressor, fan and cooler components vertically, so as to realize that the chiller assembly uses a smaller platform space. The saved space can be used to add a cooler, and two coolers can be connected in parallel to absorb more heat and thus exert a greater power capacity of the cooling unit assembly.

The overall structure is divided into three modules, namely, a lower base plate X module, a fan fixing plate X module, and a side guard plate X module. The shock-absorbing pad 20 is assembled to the compressor fixing bracket 19, and then the compressor fixing bracket 19 with the shock-absorbing pad 20 assembly is fixed to the lower base plate 14 by bolts, and then the compressor 18 is fixed to the compressor fixing bracket 19 by bolts. The liquid reservoir 23 is placed in the liquid reservoir fixing bracket A22, the liquid reservoir fixing bracket B24, and the liquid reservoir fixing bracket C21, and then the liquid reservoir fixing bracket A22, the liquid reservoir fixing bracket B24, and the liquid reservoir fixing bracket C21 are connected and clamped to the liquid reservoir 23 by bolts, and then the liquid reservoir fixing bracket C21 is fixed to the lower base plate 14 by bolts.

[0015] The fan 1 is fixed to the fan fixing plate 6 by bolts, and the impeller is built into the unit to reduce the size of the protruding part of the fan, thereby using less space in the vehicle. The condenser 8 is arranged vertically, connected to the condenser fixing bracket 7, and then fixed to the fan fixing plate 6 by bolts. The refrigerator 10 is fixed to the fan fixing plate 6 by bolts, and two are placed side by side on the right side of the upper half of the condenser 8. The water pump 16 is fixed to the lower base plate 14 by nuts and placed on the left side of the lower half of the condenser 8.

[0016] During installation, first assemble the shock-absorbing pad 20, the compressor fixing bracket 19, the compressor 18 and the lower base plate 27 together, then assemble the liquid reservoir 23, the liquid reservoir fixing bracket A22, the liquid reservoir fixing bracket B24, the liquid reservoir fixing bracket C21 and the lower base plate 14 together, and then assemble the water pump 16 and the lower base plate 14 together. At this time, the lower base plate 14 module is completed; for the fan fixing plate 6 module, first assemble the fan 1, the condenser 8, the condenser fixing bracket 7, and the refrigerator 10 on the fan fixing plate 6, and then install the cold-storage pipe assembly 17 and the pressure-cold pipe assembly 15 on the condenser 8 with bolts. At this time, the fan fixing plate 6 module is completed; then assemble the lower base plate 14 module and the fan fixing plate 6 module together, and then install the cold-storage pipe assembly 17 on the inlet of the liquid reservoir 23 with bolts, and install the pressure-cold pipe assembly 15 on the compressor 18 with bolts. On the outlet, then connect the water pump to the cooler hose assembly 26 to the cooler 10 and the water pump 16, and then use the hose clamp to lock it, the side guard plate 11 module, the water outlet joint 4, the water inlet joint 5, the water inlet joint to the water pump hose 13, and the side guard plate 11 are assembled together to form the side guard plate 11 module; then assemble the side guard plate 11 module with the lower base plate 14 module and the fan fixing plate 6 module together, and then install the cooler to the water outlet joint hose assembly 25 and the water outlet joint 4 and lock it with the hose clamp, install the water inlet joint to the water pump hose 13 and the water pump 16 and lock it with the hose clamp, and fix the high and low pressure pipe assembly 12 with the refrigerator 10, the compressor 18 outlet, and the liquid reservoir 23 outlet with bolts, finally assemble the wiring harness 3 and use bolts to fix the front enclosure guard plate 2, the upper cover plate 27 with the fan fixing plate 6 module and the side guard plate 11 module to complete the high-power vertical battery chiller assembly.

[0017] During the refrigeration cycle, the compressor 18 compresses the refrigerant from a low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure refrigerant. The high-temperature, high-pressure gaseous refrigerant discharged from the compressor 18 passes through the compression-cold pipe assembly 15 to the condenser 8. After the condenser 8 dissipates heat to the air, the refrigerant is converted into a liquid state (it may also be a gas-liquid mixed state), and then flows into the liquid storage tank 23 through the cold-storage pipe assembly 17. The liquid refrigerant coming out of the liquid storage tank 23 passes through the high- and low-pressure pipe assembly 12 and flows into the expansion valve 9 for throttling and pressure reduction. The refrigerant is then converted into a gas-liquid mixed state and flows into the two parallel refrigerators 10. The two parallel refrigerators 10 respectively absorb the heat in the battery antifreeze to convert the refrigerant into a low-pressure gas state. Then, after passing through the high- and low-pressure pipe assembly 12, the gaseous refrigerant flows into the compressor 18 and is compressed again to a high-temperature, high-pressure gas state and flows into the condenser 8. This repeated cycle achieves the purpose of cooling the battery.

[0018] The utility model increases the internal space by vertically designing the main components, adds a cooler, increases the battery cooling power, and thus improves the air conditioning effect.
