Description

Pipeline two-phase flow radiator

The present invention relates to a radiator, in particular to a pipeline type two-phase flow radiator.

Due to the rapid development and application of communication equipment, the requirements for heat dissipation of equipment have become more stringent. Traditional fin-type radiators have been unable to meet the heat dissipation requirements in limited spaces. To solve this kind of heat dissipation problems, forced convection of fans is often used, or instead Water-cooled.

However, forced convection of the fan requires sufficient heat dissipation space to install the fan and consumes electric energy. Although the water cooling effect is better, it requires a larger space for cooling equipment and higher cost.

Therefore, how to solve the above problems is the direction that researchers in this field should strive for.

One purpose of the present invention is to realize the heat dissipation function of evenly distributing heat on the base and utilizing the heat dissipation fins to the maximum.

In order to achieve the above object, the present invention provides a pipeline type two-phase flow radiator, which includes: a base with an upper side and a lower side, the upper side is provided with a plurality of radiating fins; and a tube body, Embedded on the lower side surface, the tube body has a first side, a second side, and a liquid storage chamber communicated with at least one condensing end through at least one connecting portion, the second side of the tube body and the bottom of the base The sides are flush.

With this design of the present invention, the liquid storage chamber can store more working fluid, and the heat absorption area provided with the liquid storage chamber is attached to a heat source, so that a large amount of working fluid can quickly absorb heat and heat The amount of heat is transferred to the condensing end, so that the heat of the heating source will not be concentrated in the heat absorption area, thereby realizing the uniform distribution of heat in the base and the heat dissipation function of the heat dissipation fins to the maximum.
