As shown in fig. 1 to 4, a refrigeration system according to an embodiment of the present invention includes: a semiconductor chip 100 having a cold side and a hot side; a cold dissipation structure 200 connected to a cold side of the semiconductor chip 100; a heat sink structure 300 connected to the hot side of the semiconductor chip 100; the cooling circulation fan 400 is disposed corresponding to the cooling dissipation structure 200, so that the air coming out of the cooling circulation fan 400 passes through the cooling dissipation structure 200 and exchanges heat with the cooling dissipation structure 200. The heat dissipation structure 300 includes: a heat dissipating pipe 310 connected to the hot end of the semiconductor chip 100 and having a refrigerant therein; the heat dissipating steel wire 320 is connected to the heat dissipating pipe 310.

The refrigeration system carries out the circulation of heat absorption gasification and precooling liquefaction through the refrigerant in the heat dissipation pipe so as to absorb the heat at the hot end of the semiconductor chip, and then the heat is transmitted to the heat dissipation steel wire through the heat dissipation pipe to carry out heat dissipation, so that the heat dissipation process is zero in noise, and the refrigeration system can meet the application of various occasions/places with high requirements on noise.

The heat dissipation pipe 310 is disposed in contact with the hot end of the semiconductor chip 100, and is heat-exchanged in a heat conduction manner, and may be fixed by a screw. The refrigerant in the heat dissipation conduit 310 is heated and vaporized, the gaseous refrigerant flows along the heat dissipation conduit, and then precooling, liquefying and refluxing are carried out, so that the heat dissipation effect is achieved through the circulation process of heating, vaporizing and precooling and liquefying. Preferably, the heat dissipation conduit 310 is arranged in a spiral or winding manner to increase the motion range of the refrigerant vaporizing in the tube, thereby promoting precooling and liquefaction of the refrigerant and further promoting heat dissipation. The heat radiation wire 320 is disposed around the heat radiation guide tube 310 and in contact with the heat radiation guide tube 310 to perform heat exchange in a heat conduction manner, thereby promoting heat radiation of the refrigerant. Specifically, the heat dissipation conduit may be made of a material capable of conducting heat conduction in the prior art, and preferably made of a material with a high heat conduction coefficient, such as a copper pipe; the refrigerant can be a refrigerant in the prior art, such as environment-friendly refrigerant R600A/R134A and the like. The semiconductor chip is also wrapped with a heat insulation material.

In the concrete application, above-mentioned cold circulation fan is used for promoting the circulation of cold air to improve refrigeration efficiency, to a certain extent, improve this cold circulation fan's rotational speed and be favorable to the improvement of refrigeration efficiency. On the other hand, when the cooling circulation fan rotates, the main structure (driving motor, fan blades, etc.) of the cooling circulation fan vibrates, and thus, the main structure collides with the structure to generate noise.

As shown in fig. 1 and 2, in particular, the cooling structure 200 includes a cooling plate 201, and the cooling plate 201 is connected to the cold end of the semiconductor chip through the cold conducting member 110.

In some preferred embodiments, the cold dissipating plate 201 is distributed with auxiliary cold dissipating portions 210. Therefore, the cooling area of the cooling plate can be increased through the auxiliary cooling part, so that the refrigeration efficiency can be improved, the working load of the cold circulating fan can be reduced, and the working noise of the cold circulating fan and the refrigeration system can be reduced. Specifically, the auxiliary cooling portion 210 is a strip-shaped cooling plate protruding from the cooling plate 201, a plurality of strip-shaped cooling plates are arranged at intervals on the front side of the cooling plate 201 facing the inner cavity of the cabinet, and the back side of the cooling plate 201 directly contacts the cooling guide member 110 for heat transfer.

When the semiconductor cooling device is used and installed, the semiconductor chip 100 and the cold conducting piece 110 are connected with the back of the cabinet body 500 in an embedded mode, and after the heat dissipation guide pipe 310 is connected with the semiconductor chip 100, the heat dissipation guide pipe penetrates through the cabinet body 500 to be installed outside the cabinet body 500, and the semiconductor cooling device can be installed through the installation support 330; the cold circulation fan 400 is connected to the cabinet 500 through the panel 410, wherein three sides of the panel 410, which are not the outlet air, are respectively connected to the top, the left side, the right side, and the left side of the cabinet 500, and one side of the panel 410 corresponding to the outlet 461 is opposite to the cold dissipation plate 201 at the lower part, so that the panel 410 and the cold dissipation plate 201 form a sidewall of the storage cavity of the cabinet. Since the cold guide 110 is connected to the back of the cabinet 500 in an inlaid manner, there is no ventilation space between the back of the cold dissipation plate and the cabinet, and the air flowing out of the cold circulation fan can only flow through the front of the cold dissipation plate.

In some preferred embodiments, as shown in fig. 3, the cold guide member 110 is provided with an extended support 111, and the cold dissipation plate 201 is connected to the extended support 111. Therefore, a ventilation space is formed between the back of the cold dissipation plate and the cabinet body, and air coming out of the cold circulation fan 400 can pass through the front side and the back side of the cold dissipation plate 201 to take away cold, so that the refrigeration efficiency can be improved, the working load of the cold circulation fan can be reduced, and the working noise of the cold circulation fan and the refrigeration system can be reduced. Specifically, the extension supporting portion 111 and the cooling conductive member 110 may be integrally formed, for example, an integrally formed aluminum block.

In the concrete application, lead cold piece 110 and the cold plate 201 contact setting of loosing, can fix through the screw specifically, from this, the cold volume that the cold junction produced is transmitted to the cold plate 201 that looses through leading cold piece 110, and the cold plate 201 that looses contacts with the air and carries out the heat exchange to reach refrigeration effect. The air outlet 461 of the cooling circulation fan 400 corresponds to the cold dissipation plate 201, and air enters from the first air inlet 462, the second air inlet 463 and the third air inlet 464 of the cooling circulation fan 400 and flows from the air outlet 461 to the cold dissipation plate 201 through the air duct 422, and the cooling circulation fan 400 drives the air to circularly flow to exchange heat with the cold dissipation plate 201, so that the cold energy carried by the cold dissipation plate 201 is diffused, and the refrigeration is promoted.

As shown in fig. 4 and 5, the cold circulation fan 400 includes a shock-absorbing structure, a panel 410 and a fan body 420, and the fan body 420 is connected to the panel 410 through the shock-absorbing structure; the shock absorbing structure includes a shock absorbing plate 430, and the shock absorbing plate 430 is disposed between the fan body 420 and the panel 410.

Therefore, the first and second position-limiting

portions
