Abstract

The utility model discloses a heat radiation structure. A substrate is comprised. The two sides of the substrate bend downwards to form sidewalls. The substrate is provided with heat radiation pieces perpendicular to the substrate, wherein the cross sections of the heat radiation pieces are saw-tooth shaped. The saw teeth are arranged symmetrically in left and right in a protruding-and-recessed mode. According to the heat radiation structure of the utility model, the cross sections of the heat radiation pieces are saw-tooth shaped, so that the heat radiation area is enlarged, and the weight of the product is reduced. Furthermore, air is enabled to move in a winding mode, so that the heat radiation effect is better.

Description

A kind of radiator structure

Technical field

The utility model relates to a kind of radiator structure.

Background technology

Along with the information age is constantly progressive, people's environmental consciousness constantly increases, new forms of energy are subject to people's favor, solar inverter is widely used in power industry, when inverter is worked, its heat sent is mainly by radiator heat-dissipation, and inverter heat radiation quality directly affects useful life and the serviceability of product.Existing radiator is because fin is flat panel, and area of dissipation is limited, the poor effect of heat radiation.

The utility model content

The purpose of this utility model is the defect existed for above-mentioned prior art, and a kind of radiator structure is provided.

The technical solution adopted in the utility model is, designs a kind of radiator structure, comprises substrate, its both sides are bent to form sidewall downwards, and substrate is provided with the fin that falls in this substrate, wherein, the cross section of described fin is zigzag fashion, and it is recessed symmetrical that sawtooth is left and right one protruding.

In one embodiment, described sidewall is provided with breach or the hole with inverter pallet secure fit.

Compared with prior art, apply radiator structure of the present utility model, zigzag fashion is adopted in the cross section of fin, has increased area of dissipation, alleviates the weight of product, and can make air produce moving, and then makes better heat-radiation effect.

Embodiment

Below in conjunction with drawings and Examples, utility model is described in detail.

As shown in Figure 1, the radiator structure the utility model proposes, comprise substrate, and its both sides are bent to form sidewall 2 downwards, and substrate is provided with the fin 1 that falls in this substrate, and wherein, the cross section of fin 1 is zigzag fashion, and it is recessed symmetrical that sawtooth is left and right one protruding.

Fig. 1 is the section bar schematic diagram after the utility model open die extrusion, Fig. 2 is the schematic cross-section of fin in Fig. 1, from Fig. 1 and Fig. 2, can find out, the cross section of fin 1 is zigzag fashion, it is recessed symmetrical that sawtooth is left and right one protruding, also can be symmetrical for mirror image, the wave-like on fin 1 can make the air moving, has increased the area that fin 1 contacts with air.

Fig. 3 is the finished product schematic diagram of the utility model after digital control processing, as can be seen from Figure 3, on sidewall 2, is equipped with two hook-shaped breach 4 and two above through holes with inverter pallet secure fit.

During installation, as shown in Figure 4, the heat sink size that adopts said structure, according to the fan height design that is of a size of 60 millimeters long, 60 mm wides and 25 millimeters high, is arranged in pairs or groups a three-phase inverter is arranged it on.Radiator is placed on the three-phase inverter pallet, and the hook-shaped breach 4 on the sidewall 2 of radiator of the projection on the pallet both sides is slipped into bottom by the porch of breach, by screw, pallet is fixed on radiator below.Then three-phase inverter is placed on the substrate 3 of radiator, three-phase inverter, radiator and pallet are connected and fixed.Front end at radiator is installed with fan, can be according to the caloric value increase and decrease fan of product, and air channel is by the forward direction after-blow.

The utility model, by the die sinking extrusion forming, is not limit the profile length restriction, can be adapted on multiple product, reduces the cost that repeats die sinking because of different types of machines; Because zigzag fashion is adopted in the cross section of fin, increased area of dissipation, alleviate the weight of product, and can make air produce moving, and then make better heat-radiation effect.

Claims
