Description

Micro-group groove radiator

Technical Field

The utility model relates to a radiator technical field specifically is a little crowd's groove radiator.

Background

Under the condition that the structure of the radiator is optimized to be extreme, in order to enhance the heat radiation performance of the radiator, two ways are generally adopted at present, namely embedding a heat pipe on the radiator, as shown in figure 1, 1 is the radiator, and 2 is the heat pipe; another is to embed a temperature-equalizing plate on the heat sink, as shown in fig. 2, 3 is the heat sink, and 4 is the temperature-equalizing plate.

1. For the heat radiator embedded in the heat pipe, because the heat conduction direction of the heat pipe is one-dimensional, the amplitude of enhancing the heat radiation performance is not two-dimensional high, and the heat radiation performance is slightly reduced due to the contact thermal resistance existing between the heat pipe and the heat radiator, the scheme is mostly used in the industry at present. 2. For the radiator embedded in the uniform temperature plate, although the heat conduction direction of the uniform temperature plate is two-dimensional, the contact thermal resistance still exists between the uniform temperature plate and the radiator, and in addition, the most critical point is that the uniform temperature plate is very expensive, and the scheme is rarely used in the industry.

Disclosure of Invention

Preferably, the external dimension of the heat sink is 270mm 370mm 85mm, and the material of the heat sink is 6063 aluminum material.

Preferably, the lower end of the radiator is fixedly provided with a plurality of fins.

During processing, the radiator is extruded and formed by an extruded section bar process, then a rectangular cavity is milled on the radiator by adopting a CNC machining process, and a refrigerant pipe orifice is milled on the side surface; in addition, forming a vertical micro group groove on one surface of the aluminum plate by using an aluminum plate and adopting an etching process; then, a brazing process is adopted to weld the cover plate with the vertical micro-group grooves and the refrigerant injection pipe orifice with the radiator together, and a micro-group groove cavity is formed in the radiator; and finally, vacuumizing the cavity through a refrigerant pipe orifice, injecting a refrigerant, and sealing to form the micro-group groove radiator. When the temperature is not high, the refrigerant of radiator the inside is liquid, when the chip generates heat and makes refrigerant temperature rise, the refrigerant can evaporate into gas, the in-process refrigerant of evaporation can absorb a large amount of heat of sending out from the chip, in the evaporation process, the refrigerant volume increases, pressure increase, can be along little crowd's groove to diffusion all around, the heat of middle chip is taken to the place that the temperature is lower all around, gaseous refrigerant can condense liquid back in the place that the temperature is lower all around, in the in-process of condensation, the refrigerant can release a large amount of heats and give the radiator, then the radiator is again on heat conduction fin, finally take away the heat on the fin through the air.

Compared with the prior art, the beneficial effects of the utility model are that: the heat dissipation performance of the micro-group groove radiator is greatly improved compared with that of the conventional common heat pipe radiator, the manufacturing cost is not increased, and the cost performance is very high. Because the micro-group grooves are criss-cross and intercommunicated grooves, the heat conduction direction is two-dimensional, namely heat can be diffused through the whole surface, unlike the heat pipe which is one-dimensional, the heat can be diffused only in the direction like a line, which is the reason that the micro-group groove radiator can greatly improve the heat dissipation performance; in addition, the micro-group groove structure is a part of the radiator, and has no contact thermal resistance, unlike a heat pipe and a temperature equalizing plate, the radiator is two different parts which need to be combined together, and the contact thermal resistance is generated between the two parts, and the heat radiation performance of the radiator is slightly reduced by the contact thermal resistance. Because the grooves in the micro-group groove structure are relatively tiny, the refrigerant condensed back to liquid at the periphery is easily sucked back to the place with high temperature of the middle chip due to pressure difference, and then is continuously evaporated to absorb heat, and the circulation is carried out.
