In order to make the objects, features and advantages of the present utility model more obvious and understandable, the technical solutions of the present utility model will be clearly and completely described below with reference to the drawings in this specific embodiment, and it is apparent that the embodiments described below are only some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, based on the embodiments in this patent, which would be within the purview of one of ordinary skill in the art without the particular effort to make the utility model are intended to be within the scope of the patent protection.

As shown in fig. 1-4, the utility model discloses a CPU heat dissipating device, comprising a CPU heat sink 3 mounted in a fitting manner with a CPU, wherein the CPU heat sink 3 comprises a heat sink base 31, a cold air shell 32 and heat dissipating fins 33 which are sequentially arranged in a fitting manner from bottom to top; the radiator base 3 is attached to the back of the CPU, and a cold air channel which penetrates through the inside of the cold air shell 32; the air inlet pipe 42 is connected with the air inlet end of the vortex tube 44, the hot air outlet pipe 43 is connected with the hot air outlet end of the vortex tube 44, and the cold air outlet end of the vortex tube 44 is connected with the front end of the cold air channel.

A main board 2 is arranged in the server case 1, a CPU is arranged on the main board 2, a radiator base 31 of a CPU radiator 3 is attached to the back of the CPU, and heat dissipation paste is smeared between the radiator base 31 and the back of the CPU to enhance the heat conduction effect; the air inlet pipe 42 is filled with high-pressure air, and cold air separated by the vortex tube 44 is filled into a cold air channel in the cold air shell 32 through the characteristics of the vortex tube 44, so that the whole CPU radiator 3 is cooled, and the low-temperature, efficient, stable and reliable operation of the CPU is ensured. The integrated structure is simple, the use is convenient, and the heat dissipation effect for the CPU is good.

The vortex tube 44 can instantly change the input compressed air into cool air and hot air; when in operation, compressed air is only required to be introduced into the inlet (the air inlet pipe 42) at the side of the vortex tube 44, and the air flow is continuously accelerated through the tiny nozzles, enters the interior of the vortex tube 44 at a high speed, and forms a vortex rotating at a high speed in the interior. The angular velocity is greater nearer the center of the vortex tube 44 and is lower nearer the outer wall of the vortex tube 44. Because the gas speeds of the inner ring and the outer ring are different, friction can be generated between the inner ring and the outer ring, and in fact, the vortex of the inner ring rotating at high speed drives the vortex of the outer ring to rotate by virtue of friction force, as a result, the vortex gas of the inner ring rotating can be continuously converted into rotating kinetic energy, so that the temperature is lower and lower, the temperature of the vortex of the outer ring is continuously increased by the driving of friction force, and then the vortex is respectively led out by the conical plug, so that cold air flow and hot air flow are respectively obtained. The cool air flows into the cool air shell 32 to cool down the CPU, and the hot air flows out of the server through the hot air outlet pipe 43.

Wherein, the radiator base 31, the cold air shell 32 and the radiating fins 33 are all made of copper and are welded and fixed together. The overall heat conduction and heat dissipation effect of the CPU radiator 3 is ensured.

The cooling air in the cooling air channel is matched with the cooling air flow generated by the cooling fan 5 in the server, so that the overall cooling effect in the server is improved.

The direction of the heat dissipation fins 33 is consistent with the power direction of the heat dissipation fan 5 in the server. The heat dissipation air flow generated by the heat dissipation fan 5 in the server can be used for efficiently cooling and dissipating heat of the heat dissipation fins 33, and good ventilation of the server is guaranteed.

Wherein, the cold air shell 32 is internally provided with a partition 34 at intervals in the front-rear direction. The partition 34 can separate cold air conveyed by the vortex tube 44, so that the balance of cooling and heat dissipation of the radiator base 31 (CPU) is ensured, and the CPU is enabled to dissipate heat efficiently; and the partition plate 34 is made of copper, so that heat conducted out of the radiator base 31 can be quickly transferred to the radiating fins 33, and heat is taken away through radiating wind flow generated by the radiating fan 5 in the server, so that efficient heat dissipation of the CPU is realized.

Wherein, as shown in fig. 4, the partition 34 has a wavy curved structure. The wavy partition 34 can effectively increase the contact area with cold air conveyed by the vortex tube 44, so that the heat exchange effect is improved; and effectively increases the rapid transfer of heat from the heat sink base 31.

Wherein, one end of the air inlet pipe 42 far away from the vortex tube 44 is connected with a compressor; and a controller for controlling the start and stop of the compressor and the flow rate is also arranged in the server. Automatically detecting the operation temperature of the CPU, and automatically adjusting the compressor by the controller according to the operation temperature of the CPU: when the CPU running temperature exceeds a certain set value, the compressor is started, and cold air is conveyed through the vortex tube assembly 4 to perform auxiliary heat dissipation; and along with the change of the CPU running temperature, the air supply flow of the compressor is automatically regulated, so that the dynamic regulation of the vortex tube assembly 4 on the heat dissipation and the temperature reduction of the CPU is realized, the running reliability and the running stability of the CPU are ensured, and the energy consumption is reduced.

A plurality of flow deflectors 45 are equally arranged in the flow dividing shell 41. The cold air conveyed by the vortex tube 44 is uniformly distributed through the distribution shell 41 and the guide plate 45 in the distribution shell, so that the cold air is uniformly distributed among all channels formed by the adjacent partition plates 34, and the uniform cooling and heat dissipation of the radiator base 31 (CPU) are realized.

According to the CPU heat dissipation device, the air inlet pipe 42 is filled with high-pressure air, and the low-temperature cold air separated by the vortex pipe 44 is filled into the cold air channel in the cold air shell 32 through the characteristics of the vortex pipe 44, so that the whole CPU heat radiator 3 is cooled, and the low-temperature, high-efficiency, stable and reliable operation of the CPU is ensured.
