Description

TECHNICAL FIELD

[0001] The present application relates to the field of liquid cooling cabinets, in particular to an external heat dissipation type cabinet. BACKGROUND

[0002] A liquid cooling server cabinet is a cabinet that uses liquid cooling technology to dissipate heat from servers. Traditional server cooling mainly relies on air cooling, that is, air is made to flow around server components by fans to carry away heat. The liquid cooling server cabinet, however, uses the high specific heat capacity of liquid (such as water, special coolant, etc.) to more efficiently transfer the heat generated by the server.

[0003] Generally, liquid cooling servers use immersion liquid cooling. In this way, server components (such as motherboards, CPUs, GPUs, etc.) are directly immersed in the cooling liquid. The cooling liquid directly contacts the heat generating components and absorbs heat. This way of dissipating heat is very efficient because the cooling liquid can maximize contact with the heat source. For example, some immersion liquid cooling systems use fluorinated liquid as the cooling liquid, which has good insulation and heat conduction properties, can well protect electronic components and effectively dissipate heat. However, this way has higher requirements for the cooling liquid, which needs to have good electrical insulation, chemical stability and compatibility to avoid damage to the server hardware.

[0004] Because the cooling liquid needs to be re-cooled after warming up before it can flow back, a radiator needs to be set up. The radiator has two ways, active and passive. The passive one is a heat dissipation fin tube, which can dissipate heat through fins. The active one is water cooling, etc. Due to the limitations of the existing radiator structure, it cannot adjust the two modes according to the needs. Practical new type content

DETAILED DESCRIPTION

[0029] The application will be further described below in conjunction with the accompanying drawings. Figures 1-7 The application will be further described below in conjunction with the accompanying drawings.

[0030] The application discloses an external heat dissipation type cabinet, which comprises a liquid cooling box 1, an inlet pipe 2, an outlet pipe 3 and a circulating pump 4. One end of the inlet pipe 2 is communicated with the inlet of the liquid cooling box 1, and the other end is communicated with the outlet of the circulating pump 4. One end of the outlet pipe 3 is communicated with the outlet of the liquid cooling box 1, and the other end is communicated with the inlet of the circulating pump 4. The cooling liquid in the liquid cooling box 1 is generally fluorinated liquid, and can also be mineral oil, organic silicon liquid, phosphoric acid dibutyl ester and other liquids without electric conductivity but with good heat conductivity.

[0031] The outlet pipe 3 is provided with a radiator 5, which comprises a connecting end head 6, a heat dissipation pipe 7 and a sleeve 8. The connecting end head 6 is provided with two ends in sealed communication with the two ends of the heat dissipation pipe 7. The connecting end head 6 comprises a connecting head 9 with gradually increased inner cavity area and a flow distribution disc 10 mounted on the connecting head 9 and located at the end with large inner cavity area. The connecting head 9 is a circular cone structure with hollow inside and through two ends, and the small end is integrally formed with a water receiving pipe 11. The outlet pipe 3 is divided into two parts, and the water receiving pipes 11 of the two connecting end heads 6 are respectively connected to the two parts of the outlet pipe 3.

[0032] The flow distribution disc 10 is provided with seven flow distribution holes 12, one in the middle and six evenly distributed around the circumference of the middle one. Each flow distribution hole 12 is connected with a heat dissipation pipe 7, and the heat dissipation pipe 7 is detachably connected with the flow distribution disc 10. Specifically, the inner wall of the flow distribution hole 12 is provided with internal threads, and the two ends of the heat dissipation pipe 7 are provided with external threads. The two ends of the heat dissipation pipe 7 are respectively inserted into the corresponding flow distribution holes 12 of the two flow distribution discs 10. The heat dissipation pipe 7 is threadedly connected with the flow distribution holes 12 of the flow distribution disc 10. In order to improve the sealing performance of the heat dissipation pipe 7 and the flow distribution disc 10, a limiting ring 13 is fixed or integrally formed near the port of the heat dissipation pipe 7. The side surface of the limiting ring 13 close to the flow distribution disc 10 is provided with an annular sealing gasket 14, which is located between the limiting ring 13 and the flow distribution disc 10.

[0033] The flow distribution disc 10 is sealingly and rotatably connected with the connecting head 9. Specifically, an annular groove is formed in the inner wall of the connecting head 9, a sealing ring is arranged in the annular groove, and the flow distribution disc 10 is in interference fit with the sealing ring. Two annular grooves are arranged, and different sealing rings are arranged in the two annular grooves. One is an O-shaped sealing ring 15, and the other is a Y-shaped sealing ring 16. An annular part 17 is integrally formed on the flow distribution disc 10, and a sealing ring 18 is arranged between the annular part 17 and the connecting head 9. The sealing connection of the flow distribution disc 10 and the connecting head 9 is realized through three-stage sealing. However, since the flow distribution disc 10 and the connecting head 9 are not fixed, the flow distribution disc 10 can rotate relative to the connecting head 9 under the condition of overcoming a certain friction force.

[0034] The sleeve 8 is detachably connected with the connector 9, specifically, the connector 9 has external threads, and the sleeve 8 has internal threads at two ends.

[0035] The heat dissipation pipe 7 and the distribution disc 10 can be regarded as an integral assembly, that is, the heat dissipation pipe 7 is directly machined with the distribution disc 10 at two ends, generally by welding.

[0036] During installation, the distribution disc 10 is connected with the connector 9 by plug-in connection.

[0037] The implementation principle of the external heat dissipation type cabinet according to the embodiment of the application is as follows: the scheme has two heat dissipation modes, when the server power in the liquid cooling box 1 is small, the heat dissipation pipe 7 can be directly used for heat dissipation, or the heat dissipation fan 19 can be installed to blow the heat dissipation pipe 7 and accelerate heat dissipation. At this time, the sleeve 8 is not installed.

[0038] Another mode is that when the server power in the liquid cooling box 1 is large, the server heat dissipation amount is large, the distribution disc 10 at one end of the heat dissipation pipe 7 is first inserted into one of the connectors 9, then the sleeve 8 is inserted and screwed with the connector 9, and finally the other connector 9 is installed. At this time, the water passage is formed between the connector 9 and the sleeve 8, and the first interface 21 and the second interface 22 are respectively connected with the water inlet and the water outlet of the water cooling tower 20.

[0039] If the outlet pipe 3 is not connected with the radiator, the outlet pipe 3 can directly flow through the water cooling tower 20, and the spray water of the water cooling tower 20 cools the outer surface of the outlet pipe 3 to make the cooling liquid recool.
