[0001] The utility model relates to the field of vehicle-mounted refrigerators, in particular to a heat dissipation structure for an embedded refrigerator. Background Art

[0002] Vehicle-mounted refrigerators include components such as compressors and digital display screens that need to dissipate heat. An embedded vehicle-mounted refrigerator is a type of vehicle-mounted refrigerator, which is usually installed in the trunk of a car. Its main body (including the inner liner and the housing) is embedded in the vehicle body, and the refrigerator door is exposed on the inner wall of the trunk. The heat dissipation of the embedded vehicle-mounted refrigerator is more difficult than that of other types of vehicle-mounted refrigerators because the compressor is embedded in the vehicle body.

[0003] In the prior art, the Chinese patent application document with the publication number CN118376031 A discloses a detachable and embedded vehicle-mounted refrigerator, which includes an embedded bottom shell, a box frame, a door body, a display panel, and a handle. Among them, a door body is connected inside the reserved window on the left side of the box frame, the door body corresponds to the refrigerator inner liner, and a display panel is arranged at the front end of the right side of the box frame. A pair of handles are respectively arranged in the middle of the left and right sides of the box frame; matrix-type heat dissipation holes are respectively arranged on the right end face and the front right end of the box frame.

[0004] The problem existing in the prior art is that both the air inlet and the air outlet are arranged on the right side of the box frame, resulting in a high temperature on the right side of the vehicle-mounted refrigerator. During the air circulation process, the high-temperature air is inhaled when the air enters from the right side, and the cooling effect is not good. Summary of the Utility Model

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a heat dissipation structure for an embedded refrigerator, which has the advantage of good heat dissipation effect.

[0006] The technical solution adopted by the utility model to solve the problem is:

[0007] A heat dissipation structure for an embedded refrigerator includes a housing with an open top, and also includes a fan and a steering shell. The steering shell is installed inside the housing; the vertical projection of the steering shell is arc-shaped, the inside of the steering shell is hollow, a steering channel is formed inside the steering shell, air inlets and air outlets are respectively arranged at both ends of the steering shell, and the fan is used to supply air to the steering channel.

[0008] As a preferred technical solution, the steering shell is composed of a top plate in a shape, a bottom plate in a shape, an inner side plate in an arc shape, and an outer side plate in an arc shape.

[0009] As a preferred technical solution, the steering channel includes an inlet section and an outlet section, and the lower part of the inlet section inclines to the right; the fan is a centrifugal fan, the outlet end of the fan is connected to the air inlet, and the lower part of the fan inclines to the right.

[0010] As a preferred technical solution, the housing includes a left housing and a right housing. The upper end of the left housing is open, and the upper end and the left end of the right housing are open. The right housing is installed at the right end of the left housing. It further includes a compressor and a circuit board. The compressor, the circuit board, and the fan are all arranged inside the right housing. An air inlet hole is provided on the right housing, and an air outlet hole is provided on the left housing.

[0011] As a preferred technical solution, it further includes an air duct housing. The air duct housing is arranged on the inner wall or the outer wall of the housing. An air duct is formed between the air duct housing and the housing. The air inlet hole and the air outlet hole are provided on the housing or the air duct housing.

[0012] As a preferred technical solution, an exhaust fan is provided beside the air outlet hole. The exhaust fan and the fan are respectively arranged at both ends of the air duct.

[0029] Refer to Figures 1 to 6 , andFigure 8 , an embedded refrigerator heat dissipation structure, comprising:

[0030] A housing 3 with an open top, further comprising a fan 5 and a steering housing 6, the steering housing 6 being installed inside the housing 3; the vertical projection of the steering housing 6 is arc-shaped, the interior of the steering housing 6 is hollow, a steering channel is formed inside the steering housing 6, an air inlet and an air outlet are respectively provided at both ends of the steering housing 6, and the fan 5 is used to supply air to the steering channel. This technology uses the steering housing 6 to convey the airflow generated by the fan 5 from one side of the housing 3 to the other side, with the air inlet far from the air outlet, which is beneficial to improving the heat dissipation effect of the vehicle-mounted refrigerator.

[0031] In a preferred embodiment, the steering housing 6 is composed of an L-shaped top plate 61, an L-shaped bottom plate 62, an arc-shaped inner side plate 63, and an arc-shaped outer side plate 64 enclosing each other. The airflow direction in the steering channel is mainly affected by the inner side plate 63 and the outer side plate 64, and the airflow has forward and leftward speeds, and can spread forward and leftward from the air outlet.

[0032] The steering channel includes an inlet section 601 and an outlet section 602, and the lower part of the inlet section 601 is inclined to the right; the fan 5 is a centrifugal fan, the outlet end of the fan 5 is connected to the air inlet, and the lower part of the fan 5 is inclined to the right. Setting the fan 5 obliquely is beneficial to reducing the overall height of the vehicle-mounted refrigerator, and when the fan 5 inhales air, it is not blocked by other parts except the housing 3, and the air supply resistance is small.

[0033] The housing 3 includes a left housing 31 and a right housing 32, the upper end of the left housing 31 is open, the upper end and the left end of the right housing 32 are open, and the right housing 32 is installed at the right end of the left housing 31; further comprising a compressor 8 and a circuit board 9, the compressor 8, the circuit board 9, and the fan 5 are all arranged inside the right housing 32; an air inlet hole a is provided on the right housing 32, and an air outlet hole b is provided on the left housing 31. Air enters from the air inlet hole a on the right housing 32, takes away part of the heat on the compressor 8 and the circuit board 9 and then enters the air duct 10, and the hot air in the air duct 10 is discharged through the air outlet hole 6 on the left housing 31, and has a large area for exhausting air. The fan 5 is used to inhale the air inside the right housing 32, and can make full use of the space above the compressor 8, reducing the volume of the embedded refrigerator heat dissipation structure. And, the fan 5, the compressor 8, and the circuit board 9 are all arranged at the same end, which can enable the inner liner 2 to separately occupy the space inside the left housing 31, keep the shape inside the inner liner 2 relatively regular, and the internal appearance surface of the embedded refrigerator is more beautiful.

[0034] It further includes an air duct housing 4 which is arranged on the inner wall or outer wall of the housing 3. An air duct 10 is formed between the air duct housing 4 and the housing 3. The air inlet hole a and the air outlet hole b are arranged on the housing 3 or the air duct housing 4. The volume of the housing 3 is relatively large. By separately arranging the air duct housing 4 and then installing the air duct housing 4 on the housing to form the air duct 10, compared with directly forming the air duct 10 on the housing 3, this technical solution is beneficial to simplifying the structure of the housing 3 and facilitating production.

[0035] An exhaust fan 15 is arranged beside the air outlet hole b. The exhaust fan 15 and the fan 5 are respectively arranged at both ends of the air duct 10. The air duct 10 extends from the right end to the left end of the housing 3, which can avoid the mutual interference and mixing of the air at the air inlet hole a and the air outlet hole b, achieving a better ventilation effect. The exhaust fan 15 and the fan 5 cooperate to supply air, increasing the efficiency of discharging hot air.

[0036] It further includes a box frame 1 covering the housing 3. The edge of the box frame 1 extends downward to form an installation ring. A third air hole c is arranged at the left end of the installation ring, and a fourth air hole d is arranged at the right end of the installation ring. The air duct housing 4 includes a sheet-shaped body, an upward flanging 41 arranged on the upper part of the body, and a downward flanging 42 arranged on the lower part of the body. The left part of the upward flanging 41 extends upward into the inner side of the installation ring, and the third air hole c is communicated with the outlet end of the air duct 10. The left end and the right end of the air duct 10 extend upward into the box frame 1, further increasing the air inlet area and the air outlet area. At the same time, it can play a good cooling role for the circuit board 9 installed on the box frame 1. The left part of the upward flanging 41 is folded upward and extends into the inner side of the installation ring, providing a larger installation space for the exhaust fan 15, and a larger exhaust fan 15 can be selected.

[0037] As Figure 7 , it is an embedded refrigerator of the present utility model.

[0038] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
