Especially in the display card test process, different positioning holes of display cards will use different structures of radiators. Because of the different positions of the positioning holes, the existing display card test radiator fixed with positioning bolts cannot be universal, which increases the test cost. Moreover, the connection mode of the heat dissipation fins is usually adhesion. During the test, the heat dissipation fins need to be tested after being firmly pasted, which increases the waiting time and reduces the efficiency. Moreover, the pasting mode is not firm.

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0019] Please refer to Figures 1-4The heat sink structure for testing the display card in the embodiment comprises a heat plate 1, and heat fins 6 installed on the heat plate 1, the bottom of the heat fins 6 is connected with the plate surface of the heat plate 1 through the heat-conducting glue, and a fan 2 is installed in the gap opposite to the heat fins 6, four adjusting holes 3 are arranged on the heat fins 6, one end of the four adjusting holes 3 is opposite to the four edges of the heat fins 6 respectively, and the heat plate 1 is fixed with the external display card through the positioning part.
[0020] In the above structure, the adjusting hole is opposite to the positioning hole of the external display card, and the positioning part is connected with the positioning hole, so that the heat plate is installed on the display card for testing, the structure of the display card is not the same, the positioning part can be moved in the adjusting hole and connected with the positioning hole of the display card, and the universality of the heat sink structure for testing various display cards is realized, so that the cost of testing is reduced.
[0021] The positioning part comprises a plurality of bolts 7 arranged in the adjusting hole 3 and the fan 2, the outer side of the bolt 7 is sleeved with a gasket 11 between the corresponding fan 2 and the heat plate 1, the two bolts 7 on the fan 2 are arranged through the heat plate 1, and the bottom of the bolt 7 is threadedly connected with a nut 12. The bolt is connected with the positioning hole of the display card after being moved in the adjusting hole, so that the universality is realized, the bolt passes through the fan and the heat plate, is matched by the nut, the fan can be conveniently installed, the bolt is prevented from being directly pressed into the soft material under the action of the gasket, the surface of the connecting part is prevented from being damaged, the pressure applied by the bolt is uniformly distributed, damage caused by local stress concentration is prevented, the friction of the contact surface is increased, and the fastening effect of the connection is improved.
[0022] In addition, the top of the gap of the heat fins 6 is formed with an enclosing plate 13. Under the action of the enclosing plate, the design effectively guides the airflow through the gap between the heat fins, avoids the short circuit phenomenon of the airflow, ensures that the air blown by the fan can flow through the entire surface of the heat fins efficiently, increases the speed of the airflow, and improves the heat exchange efficiency, thereby significantly enhancing the heat dissipation performance. Although the top is sealed by the enclosing plate, the protruding part of the heat fins is still exposed to the airflow, and the effective heat dissipation area is increased. The design combines the advantages of the closed and open heat dissipation, ensures the effective utilization of the airflow, maximizes the heat dissipation surface area, and the enclosing plate also forms a support at the top of the heat fins, thereby improving the overall strength of the heat fins.
[0023] Further, the bottom of the heat sink 1 is formed with a protrusion 9 below the fin 6. The protrusion 9 is integrally formed with the heat sink 1 and is made of copper as a heat-conducting material. Specifically, oxygen-free copper with high thermal conductivity is selected to ensure efficient heat conduction. Through this design, the protrusion can effectively conduct heat from the heat source to the fin, thereby improving the efficiency of the entire heat dissipation system. During installation, heat-conducting glue is applied to the protrusion to make the protrusion adhere to the graphics card more firmly and improve the heat conduction effect.
[0024] As Figure 1 , 3 and 4, the top of the heat sink 1 is fixed with two fixing plates 4 on both sides of the fin 6 through bolts 7. A C-shaped washer 10 is sleeved between the outside of the bolt 7 and the top plate of the fixing plate 4. Two groups of pressing strips 5 are fixed between the two fixing plates 4. The top of the fin 6 is provided with a number of slots 8 that are the same as the pressing strips 5 and are adapted to the pressing strips 5. By installing the fixing plate, the pressing strip is pressed into the slot, so part of the pressing strip is embedded in the sealing plate. Therefore, the slot can limit the pressing strip, thereby effectively improving the positioning of the fin and preventing displacement. At the same time, the locking screw is convenient to disassemble, replace or maintain. The C-shaped washer is elastically deformed when the bolt is tightened, providing continuous pressure and increasing friction to prevent loosening caused by vibration or impact. The pressing strip can also improve the adhesion of the fin and the heat sink to improve the heat conduction effect.
[0025] The working principle of the above embodiment is as follows:
[0026] By adjusting the position of the bolt in the hole, it can be suitable for the installation of graphics cards with different structures. After installation, the protrusion can improve the adhesion to the graphics card, and the fin is placed on the upper position of the protrusion. Then, the pressing strip is pressed into the slot, and the fixing plate is locked by the screw, which can facilitate the installation of the fin and improve the firmness. During testing, because the heat sink and the protrusion are made of copper, heat will be dissipated through the heat sink and also conducted to the top of the fin through the fin. The gap channel of the fin is aligned by the fan, thereby increasing the effective heat dissipation area under the sealing plate. This design combines the advantages of closed and open heat dissipation, which not only ensures the effective use of airflow but also maximizes the heat dissipation surface area.
