Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the following embodiments are intended to facilitate the understanding of the present invention and do not have any limiting effect on it.

[0034] Such as figure 1 As shown, the multi-cabinet two-phase heat dissipation system of the present invention includes a row of cabinet units I, an intermediate heat exchanger II, and an external heat dissipation unit III. Wherein, the cabinet unit I includes an internal refrigerant storage tank 1, two internal fluorine pumps 2 and an internal redundant fluorine pump 2', an internal filter 3 and 5-10 cabinets connected in sequence. Each cabinet includes a flow regulating valve 4, a flow meter 5, a shunt pipe 6, a plurality of server heat dissipation units 7 and a manifold 8 which are connected in sequence, and the flow regulating valve 4 of each cabinet is in communication with the internal ...

Abstract

The invention discloses a multi-cabinet two-phase heat dissipation system comprising a cabinet unit, an intermediate heat exchanger and an external heat dissipation unit, wherein the respective components in the cabinet unit form an internal circulation, the respective components in the external heat dissipation unit form an external circulation, and the internal circulation and external circulation exchange heat through an intermediate heat exchanger. The system directly cools the main heating components of the server in multiple cabinets or multiple cabinet rows, such as CPU chips, to improve heat dissipation efficiency and ensure server performance, and requires no large-area air conditioning refrigeration for the space in the machine room to reduce energy consumption and reduce noise.

Description

Technical field [0001] The invention belongs to the technical field of heat dissipation of data center cabinets, and particularly relates to a multi-cabinet two-phase heat dissipation system. Background technique [0002] With the development of the times, the scale and capacity of data centers are constantly expanding, and the number of cores and computing power of servers are constantly increasing. The problem of high-density and high-power heat dissipation puts forward new requirements for the cooling system of the computer room. At present, most data centers are mainly cooled by air conditioning throughout the year. Fans in the cabinets blow out hot air to exchange heat with cold air in the computer room to maintain the temperature in the cabinets. This air-cooled heat dissipation method has the problems of high energy consumption (the energy consumption of the air conditioning system accounts for about 40% of the total energy consumption of the data center), waste of cooling...
