[0002] Existing condensers usually fix the condensing pipes outside the housing, and there is a heat dissipation fan outside the housing. For example, Chinese Patent No. ZL202110714382.4 discloses a vehicle-mounted refrigerator in a trunk storage slot. A circuit main board, a compressor, a condenser, a filter, a capillary tube, an evaporator and a heat dissipation fan are installed in the cover body. There is only one heat dissipation fan for the evaporator, resulting in slow heat dissipation when the evaporator operates. Content of the Utility Model

By arranging the condenser in a long strip-shaped air duct and canceling the structure of setting the condenser on a square frame body, the volume of the condenser is effectively reduced. There are two fans at both ends of the air duct. One fan is used to introduce external air into the air duct for heat exchange with the condenser, and the other fan discharges the hot air in the air duct to the outside of the air duct. In this way, the condenser can dissipate heat quickly, ensuring the stability of the refrigeration operation of the vehicle-mounted refrigerator, and effectively replacing the traditional structure with a heat dissipation fan on one side of the condenser.

[0030] The present invention will be further described below in conjunction with the drawings and embodiments.

[0031] Refer to Figures 1 - 4 , a condenser heat dissipation structure, including an air duct 1, a first fan 2 and a second fan 3;

[0032] The air duct 1 is provided with an air inlet end 5 and an air outlet end 6;

[0033] The first fan 2 is arranged on the air inlet end 5 of the air duct 1 and is used to drive external air into the air duct 1 to assist the condenser 4 in dissipating heat;

[0034] The second fan 3 is arranged on the air outlet end 6 of the air duct 1 and is used to drive the air flow out of the air duct 1;

[0035] The condenser 4 is arranged in the air duct 1 and is located between the first fan 2 and the second fan 3; External air enters the air duct 1 along the first fan 2, passes through the condenser 4 and is discharged out of the air duct 1 along the second fan 3.

[0036] In this embodiment, the first fan 2 can be an axial flow fan, which is used to introduce external air into the air duct 1. The external air enters the air duct 1 and exchanges heat with the condenser 4. After the external air absorbs the heat generated by the operation of the condenser 4, it is discharged outside the air duct 1 under the traction of the second fan 3. The second fan 3 can be a volute fan.

[0037] The condenser 4 includes a condensation coil 7, and the condensation coil 7 is horizontally coiled on the air duct 1 and forms a number of turns of condensation pipes 701;

[0038] In this embodiment, the horizontal coiling of the condensation coil 7 on the air duct 1 can effectively increase the flow path of the refrigerant.

[0039] A first heat dissipation gap 8 for gas flow is provided between the outer side of the condensation coil 7 and the inner side of the air duct 1, and both the air inlet end 5 and the air outlet end 6 of the air duct 1 are connected to the first heat dissipation gap 8.

[0040] A second heat dissipation gap 9 for gas flow is provided between the several turns of condensation pipes 701, and both the air inlet end 5 and the air outlet end 6 of the air duct 1 are connected to the second heat dissipation gap 9.

[0041] In this embodiment, the first heat dissipation gap 8 and the second heat dissipation gap 9 are beneficial to increasing the heat exchange area between the external air and the condenser 4.

[0042] The first fan 2 and / or the second fan 3 are built into the air duct 1, so that the air duct 1 shields the noise generated by the operation of the first fan 2 and / or the second fan 3. The air duct 1 blocks the transmission of the noise generated by the rotation of the first fan 2 and / or the second fan 3 outward, effectively reducing the noise generated when the vehicle-mounted refrigerator works.

[0043] In this embodiment, after the condensation coil 7 is horizontally coiled, additional components can be provided to assist in fixing the condenser 4 in the air duct 1.

[0044] The air outlet of the second fan 3 is arranged downward, and the second fan 3 drives the air flow entering the air duct 1 to be discharged outside the air duct 1 downward of the second fan 3.

[0048] A straight flow section 11 communicating with the flow guiding section 10 is further provided in the air duct 1, and the condenser 4 is located in the straight flow section 11.

[0049] In this embodiment, after the outside air exchanges heat with the condenser 4 in the straight flow section 11, it enters the second fan 3 along the diversion section 10. The inclined diversion section 10 plays a role in buffering and guiding, avoiding the air flow passing through the second fan 3 in a direct flow manner, and further avoiding the generation of excessive wind noise.

[0050] The air duct 1 is arranged on the condensation cover 12. The condensation cover 12 is provided with a hollow inner cavity forming the air duct 1. The condensation cover 12 wraps the condenser 4 and forms a protective cover body for the condenser 4. The first fan 2 and / or the second fan 3 are arranged inside or outside the condensation cover 12.

[0051] In this embodiment, an avoidance opening 16 for extending the condensation pipe is provided between the condensation cover 12 and the first fan 2.

[0052] In this embodiment, the condensation cover 12 may be provided with connecting ears for fixing the first fan 2 and / or the second fan 3. The first fan 2 and / or the second fan 3 are fixed to the connecting ears of the condensation cover 12 by screws.

[0053] A new energy vehicle-mounted refrigerator includes a box body 13. An engine compartment 14 for installing the above-mentioned condenser heat dissipation structure is provided on the box body 13.
