A retractable retrofit heat sink

technical field

The invention belongs to the technical field of radiators, and relates to a retractable installation type radiator.

Background technique

The heat dissipation requirements of each board in the electronic equipment cabinet are high, and the fan heat sinks installed on the equipment are often due to long running time, aging and other reasons, resulting in unstable system operation or failure of the equipment as a whole due to the decline of the cooling effect of the cabinet and board. In case of crash, for example, after the satellite communication cabinet is turned on for a long time, the communication flashing problem will occur due to the decrease of the cooling effect and the high temperature of the equipment board. Therefore, it is necessary to enhance the heat dissipation effect of the equipment by adding heat sinks without changing the overall structure of the equipment. Commonly used heat sinks often have fixed specifications and sizes, and the size of the heat sink cannot be adjusted according to the actual heat dissipation requirements of the equipment, which is not suitable for the actual use requirements of temporary installation.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the deficiencies of the existing products and provide a new type of retractable heat sink installation unit whose size can be adjusted according to the actual specifications of the electronic equipment board, so as to meet the needs The installation of heat sinks solves the need for unstable operation or failure of the equipment due to excessive temperature, so that the application of heat sinks is more extensive, and the installation method is convenient and fast.

The technical scheme of the present invention is:

A retractable retrofit heat sink mainly consists of two heat sink units and a fixed plate unit. Installed heat sinks, so that the heat dissipation area of the heat sinks matches the size of the equipment, and the purpose of temporarily installing heat sinks is realized according to the maintenance requirements of the equipment.

The heat sink unit is an E-shaped structure plate 1, and its protruding support plate is used as a heat dissipation arm, and a plurality of screw holes a2 and heat dissipation columns 3 are evenly arranged on the heat dissipation arm; The rib 4, the rib 4 can be bent around the side of the E-shaped structural plate 1, and the rib 4 is provided with a plurality of screw holes a2;

The fixing piece unit is a rectangular fixing piece 5, which is provided with a plurality of through holes, and the through holes cooperate with the screw holes a2 on the E-type structural plate 1;

The two E-structure plates 1 are arranged in a staggered manner. Adjust the position and distance of the two E-structure plates 1 according to the area of the equipment that needs to be dissipated. Arrange the rectangular fixing pieces 5 on the E-structure plate 1 without the heat dissipation column 3. On one side, the upper surface of the rectangular fixing plate 5 is in contact with the E-type structural plate 1, and the lower surface is in contact with the equipment that needs heat dissipation; , the two E-type structural plates 1 and the rectangular fixing sheet 5 are fixed into one through the fixing screws, and the expansion and contraction of the heat sink is realized by adjusting the fixing position; through the cooperation of the screw holes a2 on the rib 4 and the fixing screws, the whole Retractable retrofit heat sinks are attached to equipment that needs to be cooled.

The upper surface of the through hole on the rectangular fixing plate 5 is a circular screw hole a2, and the lower surface is a flared screw hole b6, which is convenient for the installation and fixation of the fixing screw.

The heat dissipation column 3 is a cube.

Beneficial effects of the present invention: After the present invention adopts the overall structure of the radiating fin unit of the E-shaped structure flat plate and the rectangular fixing fin unit, the fastening position of the fixing screw can be adjusted to adjust the two radiating fin units to match the fixing fin unit. The size of the area can flexibly realize the expansion and contraction of the heat sink, so that it matches the size of the equipment and meets the needs of the equipment to enhance the heat dissipation effect.

Detailed ways

Below in conjunction with accompanying drawing and technical scheme, the present invention is further described:

The heat sink unit is an E-structure plate 1 (as shown in FIG. 1 , FIG. 2 and FIG. 4 ). The two heat sink units are staggered and matched with each other through the E-shaped structural plate 1, and the heat sink unit is fastened and fixed with the A side of the rectangular fixing sheet 5 (shown in FIG. 3) of the fixing sheet unit by fixing screws. The two sides of the rectangular fixing plate 5 are respectively provided with screw holes a2 corresponding to the screw holes a2 on the E-shaped structural plate 1 , and flared screw holes b6 . The flared screw hole b6 is conducive to the installation of countersunk screws and further ensures the tightness of the fit between the heat sink and the device. The fins 4 can be bent at 90 degrees around the side of the E-shaped structural plate 1. There are two screw holes a2 distributed on the fins 4. Through the screw holes a2 on the fins 4, the fixing screws are used to realize the connection between the entire heat sink and the equipment. Reinforcement and fit between the two, that is, to ensure that the B side of the rectangular fixed sheet unit 5 is attached to the device, to ensure the stability of the retrofit heat sink, and the screw hole a2 without screws can also act as a heat dissipation hole to achieve better heat radiation.

When making the rectangular fixing piece 5 of the present invention, it can be customized according to the size of the equipment.

To sum up, the heat sink unit of the present invention has simple structure, convenient and quick adjustment, low cost and good heat dissipation effect.
