Description

Liquid-cooled heat exchange structure

The invention relates to a water-cooled radiator, especially a liquid-cooled heat exchange structure.

Press, the heat exchanger used in the liquid-cooled heat dissipation system in the past is mainly formed in a water-cooled head with a hollow flow channel for the circulation of the cooling liquid, so as to connect the water pump and other components to drive the cooling liquid into the water-cooled head, thereby The water cooling head which is in contact with the heat source can take away the heat through the cooling liquid, so as to achieve the purpose of circulating heat dissipation.

In order to increase the flow time of the cooling liquid inside the water cooling head, extending the path of the cooling liquid flowing in the water cooling head through the design of the above-mentioned hollow channel is also one of the common design considerations under the development of current technology. However, the traditional common method is to form a water cooling head by stacking a plurality of sheets from bottom to top, and to form a flow channel by designing different holes on each sheet and partially communicating through stacking; but the traditional design The main system is to directly or indirectly contact the heat source with the sheet stacked at the bottom, so that although the integrity of the thermal contact area can be ensured, the heat transfer efficiency in the vertical direction (that is, the direction of heat transfer from bottom to top), There will be a gap between the sheets due to the upper and lower stacking relationship between the sheets, which will easily cause heat to accumulate in the bottom sheet and cannot be transferred upward, seriously affecting the vertical heat transfer effect. In this way, it is easy to cause the passing coolant to only take away the heat on the bottom surface, resulting in uneven heat exchange rate as a whole.

In view of this, in order to improve and solve the above-mentioned deficiencies, the inventors devoted themselves to research and combined with the application of theories, and finally proposed an invention with a reasonable design and effectively improved the above-mentioned deficiencies.

The main purpose of the present invention is to provide a liquid-cooled heat exchange structure, which can maintain the heat transfer effect in the vertical direction by changing the stacking direction. It can follow the forming direction of the sheet itself, and can also be horizontal The direction of flow, thus providing better heat transfer effect.

In order to achieve the above object, the present invention provides a liquid-cooled heat exchange structure, which includes a heat exchange member and a closing member arranged on the heat exchange member. The heat exchange member includes a plurality of vertically arranged first laminations and A plurality of second laminations, and the first lamination and the second lamination are interpenetrated and stacked to form the heat exchange member, and a flow channel is formed in the heat exchange member, and the flow channel is sealed by the sealing member; Wherein, the heat exchanging member has a thermal contact surface, and the thermal contact surface is formed by juxtaposing the bottom edges of all the first and second laminations stacked upright. In this way, each of the first and second laminates stacked vertically can maintain their vertical heat transfer effect.
