Description

Water-cooling radiator

Technical Field

The utility model discloses the radiator relates to a water-cooling radiator is applied to the power electronics trade, a water-cooling radiator that the radiating efficiency is high.

Background

When the power of the components is high, the traditional copper water-cooling radiator directly processes a heat radiation water channel through milling grooves on the substrate, so that the temperature rise of the components is high due to the small heat radiation area, and the requirements of customers are difficult to meet. And if the copper material is used completely, the cost is increased and the bearing is difficult.

Disclosure of Invention

The utility model aims to provide a water-cooled radiator of new heat dissipation technology and structure to traditional copper water-cooled radiator heat-sinking capability's limitation to and the high disadvantage of full copper heat dissipation cost, in order to improve the radiating effect, reduce cost.

The utility model discloses the following technical scheme of accessible realizes:

the utility model provides a water-cooling radiator, includes base plate, apron, a plurality of copper fin and bottom plate, the upper portion of base plate quilt the apron matches and covers, be the copper fin between base plate and the apron, a plurality of copper fins tile the setting side by side, weld through vacuum brazing between base plate, copper fin and the apron and become one, whole after the welding is impressed in the corresponding recess of bottom plate.

In a preferred embodiment of the present invention, the substrate is made of T2-Y red copper, and a double U-shaped water channel is provided.

As a preferred embodiment of the present invention, the bottom plate is an aluminum bottom plate made of AL6061, and is provided with the groove.

As the preferred embodiment of the utility model, the copper fin is four, and the material is T2-Y red copper, forms through the mould punching press, and it is interval 1.5mm, and thickness is 0.15 mm's staggered structure.

In a preferred embodiment of the present invention, the cover plate is made of T2-Y red copper and has a double U-shaped structure formed by stamping.

Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:

1. the heat dissipation area is large, and the heat dissipation effect is good.

2. The processing and welding are convenient, and the production efficiency is high.

3. The cost is low.

Detailed Description

The following description of the embodiments of the present invention is provided by way of specific examples, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein.

As shown in fig. 1, the utility model discloses a water-cooling radiator, be 1 base plate 2, 1 apron 3 and 4 copper fins 4 of T2-Y red copper including the material, the upper portion of base plate 2 is covered by apron 3 matching, is 4 copper fins 4 between base plate 2 and the apron 3, and 4 copper fins 3 tile the setting side by side, and it is a whole to weld through vacuum brazing between base plate 2, copper fins 4 and the apron 3. The whole after welding is pressed into a corresponding groove provided in the base plate 1. The base plate is an aluminum base plate of AL6061 and is machined (as shown in fig. 5).

Wherein, the base plate 2 is formed by machining and is provided with a double-U-shaped water channel (as shown in figure 2).

The copper fins 4 are formed by stamping through a die, and have a staggered structure with a distance of 1.5mm and a thickness of 0.15mm (as shown in fig. 3).

The cover plate 3 is a double-letter U-shaped structure formed by stamping a copper plate, as shown in fig. 4.

In this embodiment, when the fluid flows through the radiator, the heat of the heating device mounted on the cold plate is taken away through the high-efficiency heat exchange between the fluid and the copper fins 4, and the high-temperature fluid is cooled by heat dissipation of the heat exchanger and the like and then enters the radiator to form circulation.

To traditional water-cooling radiator, the utility model discloses water-cooling radiator obviously is superior to traditional water-cooling radiator at production efficiency, temperature rise, heat dissipation power etc. adopts copper aluminium to combine reduce cost simultaneously, improves the competitiveness.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
