Double-circulation type overhead heat pipe micro-module

Abstract

The invention provides a double-circulation type overhead heat pipe micro-module. According to the micro-module, an outdoor cooling unit adopts a design of double natural cooling module and a double outdoor cooling system, a plurality of different condensation supply modes such as air cooling, water spraying evaporation, compression refrigeration, chilled water cooling are provided, in the plurality of condensation modes, the air cooling which is a natural cooling mode is preferentially used, the water spraying evaporation, the compression refrigeration or the chilled water cooling are as a supplementary, and the overall heat discharge capacity of the micro-module and the redundant heat discharge requirements are guaranteed while a natural cooling source is fully utilized. An outdoor cooling loop adopts a mutual backup mode, wherein a first heat exchange loop and a second heat exchange loop mutually back up, any one of the two loops can be selected to operate or the two loops can operate simultaneously; a third heat exchange loop and a fourth heat exchange loop mutually back up, any one of the two loops can be selected to operate or the two loops can operate simultaneously; and when one set of heat exchange loop breaks down, the other set of heat exchange loop normally operates, so that the normal operation of one of two opposite overhead heat pipes can be guaranteed, and the heat dissipation supplement requirements of machine cabinets and the uniform heat dissipation requirements of the micro-module are guaranteed.

Description

technical field [0001] The invention relates to the field of heat removal in a machine room, in particular to a double-circulation overhead heat pipe micro-module. Background technique [0002] The integration density of cabinet servers in the computer room is getting higher and higher, and the heat generated by the server is getting larger and larger. In order to ensure that the servers in the high heat dissipation density computer room work at the most suitable ambient temperature, the current heat dissipation method of the high heat dissipation density computer room is also constantly changing. . [0003] At present, there are mainly the following methods for heat dissipation in high heat dissipation density computer rooms: [0004] One is precise air supply from the precision air conditioner. In this way, air ducts are used in the machine room to direct the cold air from the precision air conditioner to the server cabinet. The main advantage is that the cold air is dire...

Problems solved by technology

However, because the inter-row air conditioners are arranged between the racks of racks, while improving the heat dissipation effect, they need to occupy a certain amount of cabinet space, wasting the precious area of ​​the machine room, and the use of chilled water type inter-row air conditioners will introduce water into the The computer room has brought certain security risks

[0006] The third is to use the refrigeration cabinet door to replace the front and rear door panels of the cabinet in the machine room. The refrigeration cabinet door is divided into the refrigeration cabinet door using water-cooled heat exchanger and the refrigeration cabinet do
