Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation of refrigerators, and in particular relates to a heat dissipation structure of a refrigerator. Background Art

[0002] A refrigerator refers to a mechanical device that uses a compressor to change the pressure of a refrigerant gas to achieve low-temperature refrigeration. When the refrigerator is running, it needs to use a heat dissipation structure to dissipate heat. The conventional heat dissipation method is to dissipate heat through an air-cooled structure. For example, the existing patent with the publication number CN217131550U describes "an industrial refrigerator with a heat dissipation structure, including an industrial refrigerator body and a heat dissipation structure. The industrial refrigerator body is fixedly mounted on a base. The heat dissipation structure includes two fixed plates mounted on the base. A plurality of heat dissipation units are detachably mounted in the gap between the two fixed plates. A limiting component for positioning the heat dissipation unit is mounted on the side of one of the fixed plates. The heat dissipation unit includes a mounting plate, and a fan is mounted in the mounting plate." It can be seen that the application describes a common refrigerator, and multiple heat dissipation fans are designed to dissipate heat to ensure the stable operation of the refrigerator.

[0003] However, the cooling fans of the freezers in the above patents are mostly directly mounted on fixed brackets or frames without any adjustment structure, which results in that the inclination angle of the cooling fan cannot be adaptively rotated and adjusted according to actual usage requirements, thereby reducing the flexibility and convenience of the entire freezer cooling structure. Therefore, the present invention needs to improve and optimize the existing freezer cooling structure. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figures 1 to 4 , is an embodiment of the utility model, which provides a technical solution: a refrigerator heat dissipation structure, including

[0021] An adjustable heat dissipation mechanism 1 is arranged on the top of the base 2 and is located directly in front of the refrigerator body 3;

[0022] The adjustable heat dissipation mechanism 1 comprises a U-shaped frame 11 installed on the top of the base 2, a heat dissipation fan body 12 rotatably installed on the inner side of the U-shaped frame 11, and a circular rotating seat 13 rotatably arranged on the two side surfaces of the U-shaped frame 11. The model of the heat dissipation fan body 12 is DMR1530-6. When the heat dissipation fan body 12 is started, it will blow air to the surface of the refrigerator body 3 to achieve the effect of air cooling and heat dissipation. The inner surface of the circular rotating seat 13 is fixed with an axle rod that penetrates the inner side of the U-shaped frame 11 and is fixed to the side of the heat dissipation fan body 12, so that the heat dissipation fan body 12 can rotate on the inner side of the U-shaped frame 11, and when the heat dissipation fan body 12 rotates, it will rotate with the circular rotating seat 13. Similarly, when the circular rotating seat 13 is limited, the heat dissipation fan body 12 is also limited.

[0023] The push-type limiting structure includes a rectangular notch 15 opened on the inner side of the U-shaped frame 11, a pressure strip 14 movably located on the inner side of the rectangular notch 15, side slideways 17 opened on the inner walls on both sides of the rectangular notch 15 and connected to the side of the U-shaped frame 11, springs 111 and inner slides 110 installed in the side slides 17, L-shaped movable plates 16 arranged on the two side surfaces of the U-shaped frame 11 and located at the bottom of the circular rotating seat 13, a limiting clamping rod 18 welded and fixed to the top surface of the L-shaped movable plate 16, and a plurality of limiting clamping grooves 19 opened on the circumferential surface of the circular rotating seat 13, one end of the inner slide 110 is welded and fixed to the pressure strip 14, and the other end of the inner slide 110 extends to the side of the U-shaped frame 11 and is fixed to the L-shaped movable plate 16, and the top end of the limiting clamping rod 18 is inserted into one of the limiting clamping grooves 19, so that the inner slide 110 can be fixed together with the L-shaped movable plate 16 and the pressure strip 14, and the circular rotating seat 13 and the heat dissipation fan can be adjusted during daily use. The fan body 12 plays a role in stabilizing the limit. Later, if the inclination angle of the cooling fan body 12 is to be adjusted to change the air supply direction of the cooling fan body 12, it is only necessary to press the pressure bar 14 so that the inner slide bar 110 moves downward with the L-shaped movable plate 16, causing the spring 111 to be compressed and the top end of the limiting card rod 18 to move out of the limiting card slot 19, so that the limit on the circular rotating seat 13 can be released. At this time, the cooling fan body 12 can be rotated on the inner side of the U-shaped frame 11 to change the inclination angle of the cooling fan body 12. When the cooling fan body 12 is adjusted to a suitable inclination angle, the pressure bar 14 is released, and the inner slide bar 110 will move up and reset with the L-shaped movable plate 16 under the push of the spring 111, and the top end of the limiting card rod 18 will be inserted into the limiting card slot 19 at other positions, so that the circular rotating seat 13 and the cooling fan body 12 can be limited, thereby completing the re-limiting after the angle adjustment of the cooling fan body 12.

[0024] Among them, a cylindrical installation groove is opened on the inner wall of the bottom end of the side slide 17, and the bottom end of the spring 111 is inserted into the installation groove, which can limit the spring 111 and prevent the spring 111 from shifting in position. The top end of the spring 111 is fixed to the bottom surface of the inner slide bar 110.

[0025] There are circular shaft holes on both sides of the top of the U-shaped frame 11, and the circular shaft holes are matched with the shaft rod on the inner surface of the circular rotating seat 13 to allow the shaft rod to pass through smoothly.

[0026] It also includes a disassembly structure, which is arranged between the U-shaped frame 11 and the base 2. The disassembly structure includes two legs 112 welded and fixed to the bottom surface of the U-shaped frame 11, two supports 21 welded and fixed to the top surface of the base 2, a slot 22 opened on the top of the support 21, and a fixing bolt 4 penetrating between the support 21 and the leg 112. The leg 112 is inserted into the slot 22, and the leg 112 and the support 21 are connected and fixed by the fixing bolt 4.

[0027] Among them, the surfaces of the support leg 112 and the support seat 21 are provided with bolt holes corresponding to the fixing bolts 4 for the smooth penetration of the fixing bolts 4. When one end of the fixing bolt 4 penetrates to one side of the support seat 21, the nut can be put on the end of the fixing bolt 4 and rotated to tighten, so as to complete the connection and fixation of the support leg 112 and the support seat 21, and complete the installation of the adjustable heat dissipation mechanism 1. At the later stage, it is only necessary to rotate and remove the fixing bolts 4 to realize the rapid disassembly of the adjustable heat dissipation mechanism 1 and the base 2.

[0028] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
