Description

Dense fin water-cooling radiator

Technical Field

The utility model relates to a radiator technical field, in particular to dense fin water-cooling radiator.

Background

Heat sinks are auxiliary components that help high power electronic components dissipate heat, often with thermally conductive structures that increase surface area. It is to transfer heat to a heat conducting structure by the high heat conducting capacity of some metals, and then to dissipate the heat by flowing gas or liquid, so as to prevent the electronic components from burning out due to the temperature rise. The water-cooled heat sink is generally in the shape of a box with one end entering and the other end leaving, and a flow channel with a larger side wall area is formed in a heat conducting structure of the water-cooled heat sink, so that heat can be taken away when cooling liquid flows through the flow channel.

In the prior art, a part of the heat radiator with fins is an air cooling part, and because the air is ventilated along the direction of the fins, the peripheries of the fins are not provided with side walls. The radiator may be used in combination with a water cooled structure, such as the water cooled radiator bar disclosed in CN205305315U, but this structure requires a large number of parts to be assembled. Another part of the heat sink with fins is a water-cooled part, which needs to be box-shaped, but the fins are made by splicing many sheet-like parts, as disclosed in CN 202675213U. The radiator has the problems of many parts, troublesome assembly and difficult guarantee of sealing performance. CN202617585U discloses a water-cooled heat dissipation device, which discloses that first heat dissipation fins are disposed on a first temperature equalization plate, an accommodation space is formed between a cover and the first temperature equalization plate, and the first heat dissipation fins are accommodated in the accommodation space. However, according to the drawings, there is a gap between the top of the cover and the first heat dissipation fins, and the first heat dissipation fins are perpendicular to the water flow direction. This causes a problem that water flows mainly through the accommodating space via the gap, and water actually flows through between the first radiator fins to be small, which is not advantageous for improving the heat radiation efficiency.

Therefore, it is necessary to develop a new water-cooled radiator to solve the above problems.

SUMMERY OF THE UTILITY MODEL

Specifically, the cover plate is provided with a water inlet communicated with the water inlet chamber and a water outlet communicated with the water outlet chamber.

Specifically, the height of the fins is lower than that of the side walls.

Furthermore, a boss is arranged on the lower surface of the cover plate, and the protruding height of the boss is equal to the height difference between the side wall and the fin.

Specifically, the heat dissipation plate is provided with a flange at the periphery of the side wall, and a plurality of fixing holes penetrate through the periphery of the flange.

The utility model discloses technical scheme's beneficial effect is:

the utility model discloses utilize the fin to become the long and narrow runner that supplies coolant liquid to pass with the inside partition of heat dissipation box, greatly increased heat transfer area, the heat that makes on conducting the fin is guided away by the coolant liquid that passes the heat dissipation box fast, is fit for the occasion use that has the rapid cooling demand. The parts are few, the structure is simple, but the sealing performance is good.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example 1:

as shown in fig. 1 to 3, the utility model discloses a close fin water-cooling radiator, including heating panel 1 and apron 2, heating panel 1 includes bottom plate 11, parallel arrangement in a plurality of fins 12 of the upper surface of bottom plate 11 and the side wall 13 around all fins 12, apron 2 is connected with the top sealing of side wall 13, fin 12 separates into intake chamber 14, play hydroecium 15 and connects a plurality of runners 16 of intake chamber 14 and play hydroecium 15 with side wall 13 internal partitioning, bottom plate 11, fin 12 and side wall 13 integrated into one piece, the thickness of fin 12 is 0.5-0.8mm, the interval is 0.6-0.8mm, the height is 20-100mm. In this case, the fins 12 may be arranged very densely. If the fins 12 are 0.6mm thick, 0.6mm apart and 30mm high, a heat exchange area about 50 times the area of the base plate 11 is provided. The cooling liquid can flow through the fins 12 along the flow channels 16, the resistance is low, the flow speed is guaranteed, and the rapid heat discharge can be promoted. The utility model discloses utilize fin 12 to become the long and narrow runner 16 that supplies the cooling liquid to pass with the inside partition of heat dissipation box, greatly increased heat transfer area, the heat that makes on conducting to fin 12 is guided away by the coolant liquid that passes the heat dissipation box fast, is fit for the occasion that has the rapid cooling demand and uses.
