Description

The flow passage structure improvement of water cooling plant

Technical field

A kind of flow passage structure improvement of water cooling plant refers to that especially a kind of turbulence structure that in runner, is provided with is to increase the flow passage structure improvement that the sink flows body heat passes the water cooling plant of effect.

Background technology

Along with being showing improvement or progress day by day of electronic information science and technology, make electronic equipment (like computer, mobile computer, communication cabinet ... etc.) use popularization and application is more extensive day by day; Yet; Electronic equipment is when working at high speed; Electronic building brick in it can produce used heat, if can't in real time said used heat be discharged outside the electronic equipment, as easy as rolling off a log these used heat that make are hoarded in electronic equipment; The temperature that makes electronic equipment internal and interior electronic building brick thereof is constantly soaring, so cause electronic building brick because of overheatedly break down, situation such as damage or operational paradigm reduction.

In order to improve said heat dissipation problem, generally more common all is that radiator fan of installing comes forced heat radiation in electronic equipment, but because of the throughput of its radiator fan limited; Make its radiating effect be difficult to promote; And the situation that cooling extent is also limited so the dealer just seeks another kind of settling mode, promptly uses a water-cooled power converter directly to be attached on the heat generating component; Like (central processing unit (CPU), MPU, south, north bridge chips or other are because of carrying out the electronic building brick etc. that the operation meeting produces high heat); And cooling liquid is imported in the water-cooled power converter in aqua storage tank by a pumping, after the heat that cooling liquid and this water-cooled power converter are absorbed from heat generating component was done heat exchange, cooling liquid flowed out to a radiating module by a delivery port of water-cooled power converter again; Via sending said aqua storage tank again back to after the cooling; Help heat radiation by the cooling liquid circulation, reduce the heat generating component temperature, its heat generating component can be operated smoothly.

Yet,, extend another problem though said water-cooled power converter can improve the problem of utilizing the air-flow heat radiation; Be that water-cooled power converter is close to the end face (being heat-absorbent surface) by this heat generating component; Inject runner in the said water-cooled power converter generation heat exchange action that circulates by cooling liquid again, however since said cooling liquid to be trapped in the time of water-cooled power converter too short so that cooling liquid cmpletely enough heats (being heat exchange) of absorption not as yet; Just derive by said delivery port fast immediately; Institute causes its heat to pass poor effect, and then makes radiating effect extremely not obvious so that the water-cooled function is had a greatly reduced quality.

The inner flow passage of oil-to-water heat exchanger structure is unidirectional level and smooth runner; So cooling liquid is shorter the dead time in these runners; Cause the thermal source of taking away promptly less, it is obviously not good therefore to cause whole heat exchanger effectiveness and heat to pass effect, and its relative radiating effect is more undesirable; Present technique has disadvantage:

1. heat exchanger effectiveness is not good;

2. radiating effect is not good.

Because above-mentioned drawbacks, the present inventor innovates improvement to be engaged in the sector experience for many years, to concentrate on studies, and successfully the present invention is accomplished in research and development finally, is the invention that a tool effect is promoted in fact.

Summary of the invention

For solving the shortcoming of above-mentioned technology, the application's main purpose provides a kind of fluid that makes and produces separation eddy lifting flow field turbulence intensity, and then increases the flow passage structure improvement that heat passes the water cooling plant of usefulness.

For reaching above-mentioned purpose, the application provides a kind of flow passage structure improvement of water cooling plant, comprises: a heat conduction body; Have at least one runner and an inlet and an outlet; Said runner is arranged at this heat conduction body interior, and said runner has a slot part and a top, and this slot part and this top interconnect closed configuration and become said runner; And one of them is provided with at least one spoiler this slot part and this top, and this inlet and this outlet are communicated with the two ends of this runner respectively.

By said runner the design of spoiler is set, increases the heat exchanger effectiveness of heat radiator body, make the fluid that passes through produce separation eddy and promote the flow field turbulence intensity and promote heat and pass usefulness.
