According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, provide services, and guarantee services. As an electronic device, the internal structure of the server is very complex, but it is not much different from the internal structure of an ordinary computer, such as: CPU, hard disk, memory, system, system bus, etc.

[0003] At present, most servers use heat dissipation fins to dissipate the heat accumulated inside the server housing, and then use a heat dissipation fan to dissipate heat. The heat dissipation speed is slow. In view of this, the present utility model is proposed. Utility Model Content

The outer wall of the heat-conducting copper tube contacts the side wall of the heat dissipation fin.

[0009] Optionally, the heat sink itself is made of a heat-conducting material, and refrigeration inner protrusions are provided inside both sides of the heat sink, and the two refrigeration inner protrusions are located inside the refrigeration cavity, and the side walls of the two refrigeration inner protrusions are adhered to semiconductor refrigeration sheets through a first thermal conductive silicone grease, and heat dissipation fins are provided on one side of the semiconductor refrigeration sheet, and a heat dissipation fan is fixed on one side of the heat dissipation fins, and the external cover of the heat dissipation fan is provided with a protective cover, and the protective cover is fixed to the outer wall of the heat sink by screws.

[0010] Optionally, the bottoms of the plurality of server ends are all installed via a second thermal conductive silicone grease and heat sink fins.

[0011] Optionally, cover plates are fixed to the front and rear ends of the cabinet and the heat sink, and embedding grooves for installing the heat sink are evenly spaced in the middle of the two cover plates located at the front end of the cabinet, and a protective cover is provided on the outside of each embedding groove, and each protective cover is fixedly mounted on the side wall of the cover plate.

[0012] Optionally, a timing controller is fixedly installed on the surface of the cover plate at the front end of the heat sink, and a display screen and control buttons are respectively provided on the surface of the timing controller.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0015] 1. The utility model can quickly take away the heat of the server end by arranging heat dissipation fins matching the number of the server end inside the cabinet and cooperating with the coolant in the heat-conducting copper tube. Considering that after the coolant circulates to take away the heat, the coolant has a certain amount of heat, which will also lead to a decrease in the heat dissipation effect. Therefore, a refrigeration cavity for cooling the coolant is arranged at the front end of the coolant entering the coolant tank and the heat-conducting copper tube to help the coolant be in a low temperature state, so that the heat accumulation will not affect the heat dissipation effect due to the superposition of the number of cycles;

[0016] 2. The utility model takes into account the energy-saving requirements of the device and can use an infrared sensor in conjunction with a timing controller to regularly monitor the temperature inside the cabinet. When the temperature at the server end is normal, conventional heat dissipation can be performed through the heat dissipation fins. When the temperature is too high, the circulation pump and the semiconductor refrigeration sheet (24) are started to cool the refrigeration cavity, thereby using the refrigerant in the refrigeration cavity to quickly recover the heat absorbed by the coolant inside the heat-conducting copper tube.

[0017] The specific implementation modes of the present utility model are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The utility model is now described in further detail with reference to the accompanying drawings.

[0029] See also Figures 1 to 6 The utility model provides a technical solution: a rapid heat dissipation structure for a server, comprising a cabinet 1 and a plurality of server terminals 2, wherein a frame 3 for mounting the plurality of server terminals 2 is provided inside the cabinet 1, a heat dissipation seat 4 is fixedly installed at the lower end of the cabinet 1, and a self-locking universal wheel 5 is provided at the bottom of the heat dissipation seat 4;

[0030] The interior of the heat sink 4 is separated into a refrigeration chamber 26 and a functional chamber by a partition 25. A machine case 6 and a coolant tank 7 are respectively fixed inside the functional chamber. A circulating pump 8 for pumping coolant is provided inside the machine case 6. The output end of the circulating pump 8 is connected with a heat-conducting copper tube 9. The middle section of the heat-conducting copper tube 9 is coiled around the middle of a plurality of heat-dissipating fins 10. The other end of the heat-conducting copper tube 9 passes through the refrigeration chamber 26 and extends to the bottom of the partition 25 to communicate with the coolant tank 7. The other side of the coolant tank 7 passes through the interior of the machine case 6 through a connecting tube 12 and is connected with the negative pressure end of the circulating pump 8.

[0031] The front end of the heat-conducting copper tube 9 is also located inside the refrigeration cavity 26. The interior of the refrigeration cavity 26 is provided with refrigerant. The outer wall of the heat-conducting copper tube 9 contacts the side wall of the heat-dissipating fin 10. A plurality of heat-dissipating fins 10 are respectively installed at the lower ends of a plurality of server ends. Considering that the current server cabinet 1 generally adopts the heat-dissipating fin 10 and the heat-dissipating fan 15 for heat dissipation, but the heat-dissipating efficiency is slow and it is impossible to cool down quickly when the radiator is running at high speed. The utility model arranges heat-dissipating fins 14 matching the number of the server ends 2 inside the cabinet 1 to cooperate with the coolant in the heat-conducting copper tube 9 to quickly take away the heat of the server end 2. Considering that the coolant circulates and takes away the heat, the coolant has a certain amount of heat. It will also lead to a decrease in the heat dissipation effect. Therefore, a refrigeration chamber 26 for cooling the coolant is set at the front end where the coolant enters the coolant tank 7 and the heat-conducting copper tube 9 to help the coolant be in a low-temperature state, and will not cause heat accumulation and affect the heat dissipation effect as the number of cycles is accumulated, thereby achieving rapid heat dissipation; when the refrigeration chamber 26 is refrigerated, it mainly works through the semiconductor refrigeration plate 24, and the low temperature released by the refrigeration end is transferred to the refrigerant in the refrigeration chamber 26 through the refrigeration inner convex end 11. The heat on the cooling fins 10 is taken away by the coolant circulation, and the coolant with temperature is cooled by the refrigeration intensity, ensuring that the temperature of the coolant itself will not be too high when taking away heat through the cooling fins 10, thereby affecting the heat dissipation effect.

[0032] Among them, the material of the heat sink 4 itself is a heat-conducting material, and refrigeration inner protrusions 11 are provided inside both sides of the heat sink 4, and the two refrigeration inner protrusions 11 are located inside the refrigeration cavity 26. The side walls of the two refrigeration inner protrusions 11 are adhered to the semiconductor refrigeration sheet 24 through the first thermal conductive silicone grease 13, and a heat dissipation fin 14 is provided on one side of the semiconductor refrigeration sheet 24. A heat dissipation fan 15 is fixed on one side of the heat dissipation fin 14, and a protective cover 16 is provided on the outer cover of the heat dissipation fan 15. The protective cover 16 is fixed to the outer wall of the heat sink 4 by screws. By arranging the heat dissipation fan 15 and the heat dissipation fin 14, the heating end of the semiconductor refrigeration sheet 24 is heat-dissipated.

[0033] Among them, the bottoms of multiple server ends 2 are installed with the heat sink fins 10 through the second thermal grease 17. The second thermal grease 17 is provided to transfer heat between the heat sink fins 10 and the server ends 2. The excellent thermal conductivity of the thermal grease itself is utilized to transfer heat from the server end 2 shell to the heat sink fins 10.

[0034] Among them, cover plates 18 are fixed to the front and rear ends of the cabinet 1 and the heat sink 4. Embedding grooves for installing the heat dissipation net 19 are evenly spaced in the middle of the two cover plates 18 located at the front end of the cabinet 1, and a protective cover 20 is provided on the outside of each embedded groove. Each protective cover 20 is fixedly installed on the side wall of the cover plate 18. By setting the heat dissipation net 19, the internal temperature of the cabinet 1 is assisted in heat dissipation, which is beneficial to the low temperature released by the air conditioner in the computer room to assist in cooling the cabinet 1.

[0035] Among them, a timing controller 21 is fixedly installed on the surface of the cover plate 18 located at the front end of the heat sink 4, and a display screen and control buttons are respectively provided on the surface of the timing controller 21. The upper end of the timing controller 21 is connected to the temperature sensor 22 circuit on the side wall of the cabinet 1 through a wire. The monitoring end of the temperature sensor 22 passes through the side wall of the cabinet 1 and is located inside the cabinet 1. By arranging the temperature sensor 22 in conjunction with the timing controller 21, it is convenient for the user to perform timed detection of the internal temperature of the cabinet 1.

[0036] Among them, a perspective window 23 for checking the coolant level in the coolant tank 7 is also installed on the surface of the cover plate 18 located at the front end of the heat sink 4, and the coolant tank 7 itself is made of a perspective material. By setting the perspective window 23 and the coolant tank 7 itself being made of a perspective material, it is convenient for the user to know whether the coolant in the coolant tank 7 needs to be filled or replaced.

[0037] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
