A two-phase flow cooling device

Abstract

The invention, which belongs to the technical field of cooling of electronic equipment, discloses a two-phase flow cooling device, so that a problem that the existing two-phase flow cooling device can not be applied to cooling of small and medium-sized electronic equipment in the prior art can be solved. The two-phase flow cooling device comprises a cooling loop formed by a working medium pump, an evaporation heat exchange flow passage, a condenser and a connecting pipe. The working medium pump consists of a pump body and a drive motor; the pump body includes a pump body rotor; and the drive motor is used for driving the pump body rotor to make rotation. Besides, the two-phase flow cooling device also includes a fan; an air inlet or an air outlet of the fan is opposite to the condenser; and the fan, the pump body rotor, and a rotor of the drive motor are connected to a same rotating shaft. According to the invention, the provided two-phase flow cooling device can be applied to a small-sized or medium-sized electronic device.

Description

technical field [0001] The invention relates to the technical field of electronic equipment cooling, in particular to a two-phase flow cooling device. Background technique [0002] With the rapid development of electronic technology, while the power of electronic equipment is getting higher and higher, the volume is getting smaller and smaller, which inevitably increases the heat generation of the equipment, and as the temperature increases, the failure rate of electronic equipment Exponential growth. Therefore, the cooling of electronic equipment becomes very important. [0003] In order to realize the cooling of electronic equipment, there are traditional cooling technologies such as air cooling or water cooling in the prior art. Among them, the heat dissipation capacity of air cooling technology is limited, and the cooling efficiency is low, especially when the ambient temperature rises, its heat dissipation capacity deteriorates significantly. ; and water-cooling techn...

Problems solved by technology

[0005] However, in the prior art, two-phase flow cooling devices are mostly used in the heating field of large-scale electronic equipment. In the field of small and medium-sized electronic heating equipment, the miniaturization of the system cannot be realized due to the limitation of the system form, so it is usually not possible to integrate the entire system Embedded in devices with limited space
