Description

Multi-channel aluminum radiator

technical field

The utility model relates to the field of hardware products, in particular to a multi-channel aluminum radiator.

Background technique

With the continuous development of the electronic information industry, the operating frequency and speed of current computer processors, such as central processing units or display card processors, are constantly increasing, and the heat generated by them is also increasing, and the temperature is rising, which seriously affects the Operational performance and stability of electronic components. Therefore, in order to improve the heat dissipation performance, almost all current processors are equipped with a corresponding heat dissipation device to operate at a normal operating temperature, thereby avoiding performance degradation or even burning problems.

The heat dissipation device in the prior art has two modes of active heat dissipation and passive heat dissipation. Passive heat dissipation generally dissipates heat through heat exchange between heat sinks and air.

In many occasions, when the power of electronic products is high and the heat dissipation is large, it is difficult to quickly cool down the temperature of electronic products only by relying on the two methods of active heat dissipation and passive heat dissipation, and the heat dissipation effect needs to be improved. At the same time, in order to improve the heat dissipation effect, the heat dissipation area of the radiator needs to be made very large, which takes up a large space and is not easy to install.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a multi-channel aluminum heat sink that combines water cooling and air cooling, has good heat dissipation effect, occupies a small volume, and is easy to install.

The technical solution adopted by the utility model is: a multi-channel aluminum radiator, including two side plates arranged in parallel, which are hollow and flat and connected in parallel to several heat dissipation partitions between the two side plates, arranged on adjacent The hollow heat dissipation fins between the heat dissipation partitions are connected to the ends of the two side plates and are respectively packaged on the two covers outside the heat dissipation partitions at the outermost sides. The heat dissipation partition and the hollow heat dissipation fins are connected to form a cavity; the cover is provided with a liquid inlet for filling the cooling medium into the cavity and a liquid outlet for discharging the cooling medium inside the cavity ; The cover, heat dissipation partitions, and heat dissipation fins all include an anti-corrosion layer, an aluminum sheet layer and a heat conversion layer coated on the surface of the aluminum sheet layer to convert heat into infrared rays from the inside to the outside.

A further improvement to the above technical solution is that the heat dissipation fins are provided between adjacent heat dissipation partitions in a zigzag shape.

A further improvement to the above technical solution is that the sawtooth angle of the heat dissipation fins is 30°-40°.

A further improvement to the above technical solution is that the sawtooth angle of the heat dissipation fins is 35°

A further improvement to the above technical solution is that two sets of mounting pieces extend relatively from the side plate to the side away from the heat dissipation partition, and the mounting pieces are provided with waist-shaped holes.

The beneficial effects of the utility model are:

1. On the one hand, several heat dissipation partitions are arranged between two parallel side plates, and heat dissipation fins are arranged between adjacent heat dissipation partitions to form several heat dissipation channels for simultaneous heat dissipation, with high heat dissipation efficiency and good effect In the second aspect, the liquid inlet, the liquid outlet, the cover, the heat dissipation partition, and the heat dissipation fins form a cavity, and a cooling medium is provided inside to realize water cooling and heat dissipation, and the heat exchange with the heat dissipation fins is carried out quickly through the cooling medium , reduce the heat dissipation fin temperature, and further improve the heat dissipation effect. In the third aspect, the cover, heat dissipation partitions, and heat dissipation fins all include an anti-corrosion layer, an aluminum sheet layer, and a heat conversion layer coated on the surface of the aluminum sheet layer to convert heat into infrared rays from the inside to the outside. The sheet layer is easily corroded, and the inner surface of the aluminum sheet is coated with an anti-corrosion layer to prevent the aluminum sheet from being corroded by the cooling medium. The aluminum sheet conducts heat quickly and can quickly exchange heat with the cooling medium to cool down. At the same time, the aluminum The temperature energy of the film-making layer is transferred to the heat conversion layer and converted into infrared radiation to the surroundings, further improving the heat dissipation effect.

2. The heat dissipation fins are arranged between adjacent heat dissipation partitions in a zigzag shape. Compared with the linear structure, the zigzag structure greatly increases the surface area of the heat dissipation fins, thereby increasing the heat dissipation area and further improving the heat dissipation effect.

3. The sawtooth angle of the heat dissipation fins is 30°-40°. If the sawtooth angle is too large, the surface area of the heat dissipation fins will not increase much, which is not conducive to a large increase in the heat dissipation area. If the sawtooth angle is too small, there will be too many serrations. Adjacent serrations will block the flow of air around each other, which is not conducive to the heat exchange between the cooling fins and the surrounding air. Experiments have proved that when the sawtooth angle of the cooling fins is 30°-40°, preferably 35°, At this time, the heat dissipation effect is the best.

4. There are two sets of installation pieces extending from the side plate to the side away from the heat dissipation partition, and there are waist-shaped holes on the installation pieces. Through the installation pieces and waist-shaped holes, the entire radiator is installed in a place where the temperature of the electronic equipment is high. Easy to use.

The sawtooth angle of the heat dissipation fins 130 is 30°-40°. If the sawtooth angle is too large, the surface area of the heat dissipation fins 130 will not increase much, which is not conducive to a large increase in the heat dissipation area. If the sawtooth angle is too small, there will be too many sawtooths. Adjacent sawtooths will block the flow of air around each other, which is not conducive to heat exchange between the cooling fins 130 and the surrounding air.
