[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1As shown, the air-cooled heat dissipation test cover includes a base 100. A recessed area 110 is provided in the middle of the base 100, and the recessed area 110 penetrates the base 100. A heat dissipation device 200 is provided in the recessed area 110 and is fixedly connected to the base 100. The heat dissipation device 200 includes a heat dissipation plate 210, an air-cooling device 220, and a plurality of U-shaped heat conduction pipes 230. The heat dissipation plate 210 is used to contact the product to be tested. The air-cooling device 220 is disposed above the heat dissipation plate 210. The U-shaped heat conduction pipes 230 are used to connect the heat dissipation plate 210 and the air-cooled heat dissipation device 200.

[0027] In the working state of this embodiment, the base 100 is placed around the product to be tested, such as around a chip, so that the product to be tested is located in the recessed area 110. Then, the heat dissipation device 200 is connected to the base 100, so that the heat dissipation plate 210 contacts the product to be tested. When the product to be tested encounters a high current and high voltage environment in the test environment, the surface of the product to be tested will generate high temperature, and its heat will be transferred to the heat dissipation plate 210. Since the air cooling device 220 is provided on the top of the heat dissipation plate 210, and the air cooling device 220 is in contact with the heat dissipation plate 210 through the U-shaped heat conduction pipe 230, the high temperature of the surface of the product to be tested will be transferred to the air cooling device 220 through the heat dissipation plate 210. Finally, the heat is carried away by the circulation of air, thereby completing the heat dissipation work.

[0028] Compared to existing technologies, this application rapidly absorbs the heat conducted by the product under test through a circulation system, significantly reducing the core temperature. Compared to traditional water cooling, it offers better stability and safety: with no liquid involved, there is no risk of leakage, no damage to the hardware, stable and reliable operation, and greater peace of mind when using it.

[0029] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 2 As shown, a groove 211 is formed on the top of the heat sink 210. The U-shaped heat pipe 230 includes a bent portion 231 at the bottom and extended portions 232 extending upward in a straight line on both sides. The bent portion 231 is accommodated in the groove 211. A pressure member 240 is provided in the groove 211. The pressure member 240 is connected to the bent portion 231, so that the bent portion 231 can be pressed against the groove 211. This ensures that the U-shaped heat pipe 230 and the heat sink 210 are in close contact, thereby ensuring that the high temperature of the surface of the product under test is transferred to the air-cooling device 220 through the heat sink 210, and finally the heat is carried away by the circulation of air.

[0030] Furthermore, based on the above embodiments, such as Figure 2As shown, the air-cooling device 220 includes a plurality of heat sinks 221 arranged at preset intervals on the extension portion 232. The heat sinks 221 are laid perpendicular to the extension portion 232. An electric fan 222 is arranged between the heat sinks 221. When the high temperature of the product surface is transferred to the U-shaped heat pipe 230 through the heat sink 210, it will be further transferred to the heat sinks 221. At this time, the electric fan 222 can be turned on to blow air onto the heat sinks 221. Finally, the heat on the heat sinks 221 is carried away by the circulation of the air, thereby completing the heat dissipation work.

[0031] Furthermore, based on the above embodiments, such as Figure 2 As shown, the pressure component 240 includes a connecting plate 241 and a pressure plate 242. The connecting plate 241 is located inside the groove 211 and is sleeved on the bent portion 231. The pressure plate 242 is connected to the base 100. A spring 243 is provided between the connecting plate 241 and the pressure plate 242. Since the pressure plate 242 is fixed on the base 100, the spring 243 can provide a downward preload to the connecting plate 241, thereby making the connecting plate 241 contact with the groove 211, thus ensuring a tight contact between the U-shaped heat pipe 230 and the heat sink 210.

[0032] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, an annular groove 120 and a positioning groove 130 opposite to each other are provided on the base 100. The annular groove 120 is located above the positioning groove 130. The pressure plate 242 is engaged in the positioning groove 130. A positioning ring 140 is fixed in the annular groove 120. In this way, the positioning groove 130 can limit the pressure plate 242 in the horizontal direction. The positioning ring 140 and the annular groove 120 cooperate with each other to fix the pressure plate 242 on the base 100.

[0033] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, a plurality of fixing holes 212 are provided at the bottom of the heat sink 210, and a positioning screw 111 matching the position of the fixing holes 212 is provided at the edge of the recessed area 110. When the heat sink 200 contacts the base 100, the positioning screw 111 is inserted into the fixing hole 212, thereby fixing the heat sink 200 to the base 100.

[0034] Furthermore, based on the above embodiments, such as Figure 4As shown, a cover 300 is provided above the base 100, a pressure block 310 is provided on the top of the cover 300, and a handle 320 is provided on one side of the pressure block 310. By operating the handle 320, the pressure block 310 can be controlled to press down on the cover 300, thereby allowing the cover 300 to press down on the base 100 to ensure the flatness around the product under test, and thus allowing the heat dissipation device 200 to better contact the product under test.

[0035] Furthermore, based on the above embodiments, such as Figure 4 As shown, latches 330 are provided on both sides of the cover 300. The latches 330 are axially connected to the cover 300. The latches 330 are used to hold the edge of the product under test, such as the edge of the circuit board of the chip under test, so that the contact between the entire product and the product under test is more stable.

[0036] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
