Description
Technical Field
The invention relates to the field of heat dissipation, in particular to a radiator and a server.
Background
With the intensive development of servers, chip sizes have tended to decrease. The reduction in chip size results in an increase in heat flux density per unit area of the chip, with a consequent rise in the risk of high temperatures. In order to avoid the occurrence of chip failure caused by high temperature of the chip as much as possible, the radiator is required to be used as a main means for radiating the chip. In the air-cooled server, the radiator absorbs heat generated by the chip and transfers the heat to the air through convection heat exchange, so the key of enhancing the heat exchange of the radiator is to enhance the convection heat exchange efficiency, and the common means is to increase the heat exchange area of the radiator. However, the limited space size and the weight requirement of the radiator mean that the heat exchange area cannot be infinitely increased, so how to further increase the heat exchange efficiency in the limited space is one of the problems to be solved.
The traditional fin type radiator has the advantages that the fins are single integral in the length direction, the structure is simple, the adjacent radiating fins are regularly arranged in parallel, and the radiating effect is poor. And the radiator with unique shape, such as staggered arrangement or shutter teeth, can improve the heat exchange efficiency by 8% -10% compared with the traditional parallel fin radiator, and the radiator with unique shape can increase the heat exchange strength but also increases the wind resistance.
Aiming at the problems that the radiator in the prior art is single in structure and affects the radiating effect, no effective solution exists at present.

In some embodiments, further comprising:
and the transverse connecting piece is connected with the elastic connecting piece of each movable fin row.
Specifically, as shown in fig. 2, the transverse connection member 33 connects the elastic connection members 32 of each movable fin row, so that the maximum rotation angle of each movable fin row can be limited, and the air flow passage is prevented from being blocked by the excessive rotation angle.
