Description

Heat converter structure

Technical field

The present invention refers to a kind of heat converter structure that improves hot transfer efficiency especially relevant for a kind of heat exchanger.

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 popularize day by day and use more extensive; Yet; Electronic equipment electronic building brick in it when working at high speed can produce used heat; If can't in time aforementioned 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, and 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.

And prior art is in order to improve above-mentioned heat dissipation problem, and 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; Again via sending aforementioned aqua storage tank again back to after the cooling; So help heat radiation by the cooling liquid circulation, reduce the heat generating component temperature, its heat generating component can be operated smoothly.

Yet; Though said water-cooled power converter can improve the problem of utilizing the air-flow heat radiation; But extend another problem, promptly water-cooled power converter is close to the relation that end face (being heat-absorbent surface) by this heat generating component only concentrates on same place, make cooling liquid in the water-cooled device only have a undermost fluid partly and heat-absorbent surface produce heat exchange action; And fluid does not at the middle and upper levels produce heat exchange with heat-absorbent surface; And it is also too short that said cooling liquid is trapped in time of water-cooled power converter, to cause cooling liquid cmpletely enough heats (being heat exchange) of absorption not as yet, just derived by aforementioned delivery port fast immediately; Institute causes its heat to pass poor effect so that the water-cooled function is had a greatly reduced quality, and then makes the radiating effect utmost point not show.

Because of prior art oil-to-water heat exchanger inside configuration runner is unidirectional level and smooth runner; So cooling liquid is shorter the dead time in these runners, the thermal source of then taking away is promptly less, therefore; It is obviously not good to make whole heat exchanger effectiveness and heat pass effect, and its relative radiating effect is more not desirable; So prior art has disadvantage:

1. heat exchanger effectiveness is not good;

2. radiating effect is not good.

Because above-mentionedly commonly use the drawbacks that article are derived; The creator of this case exhausts its intelligence then, innovates improvement to be engaged in the sector experience for many years, to concentrate on studies; Finally successfully this part " heat converter structure " case is accomplished in research and development, is the creation that a tool effect is promoted in fact.

Summary of the invention

For solving the shortcoming of above-mentioned prior art, the application's main purpose provides a kind of fluid that makes to produce separation eddy lifting flow field turbulence intensity, and then increases the heat converter structure that heat passes usefulness.

For reaching above-mentioned purpose, the application provides a kind of heat converter structure, comprises: a body, a first flow group, second a runner group, first lid, second lid; Said body has one first side, second side and one the 3rd side, and the mutual correspondence of this first and second side is located at this body both sides, and first and second side of the 3rd side and this is vertical to be connected and to be provided with a water inlet and a delivery port; This first flow is mounted on said first side; Have one first helical flow path and one second helical flow path; This first and second helical flow path is interconnected, and is communicated with said water inlet and this delivery port, and said first and second helical flow path side of this body relatively has plural spoiler; Said second runner is mounted on said second side; Have a triple helical runner and one the 4th helical flow path; This third and fourth helical flow path is interconnected, and is communicated with said water inlet and this delivery port, and said third and fourth helical flow path side of this body relatively has plural spoiler; This first lid correspondence covers said first side; This second lid correspondence covers said second side.

Design by the both sides spiral type runner of said heat converter structure; Must increase the heat exchanger effectiveness of heat exchanger; And the wall that sees through in these spiral type runners is provided with spoiler, and the fluid that order is passed through produces separation eddy lifting flow field turbulence intensity lifting heat and passes usefulness.
