Description

Flow-dispersing type radiator, air conditioner frequency converter with same and electronic equipment

Technical Field

The utility model relates to a heat dissipation field especially relates to a scattered flow type radiator, and have air conditioner converter, electronic equipment of this radiator.

Background

At present, a plurality of heating components are arranged in the electric appliance, the heat of the heating components needs to be timely and effectively dissipated, and the use effect and the service life of the electric appliance can be influenced if the heat cannot be timely and effectively dissipated. In the field of electronic devices, in order to control the temperature of an electronic component within a proper temperature range, a heat sink is usually fixed on the surface of the electronic component, and fins on the heat sink diffuse heat outwards, thereby reducing the temperature of the electronic component. Or in the air conditioning field, the converter module plays a power conversion and enlargies effect in whole converter, wherein because switching loss and the resistance of module itself, can produce the heat in its working process, the unit power that the converter corresponds is big more moreover, calorific capacity is big more, if these heats are not in time dispelled, can influence module performance or even burn out the module.

At present, the common heat dissipation modes in the industry mainly include forced convection heat dissipation by fans, radiation heat dissipation by cooling fins, heat dissipation by cooling tubes and water cooling heat dissipation. In contrast, the water cooling heat dissipation method has the advantages of better heat dissipation effect and less noise. However, the existing water-cooling heat dissipation mode mostly adopts a refrigerant pipeline and a heat dissipation plate, namely, the heat source transfers heat to a heat dissipation plate through heat-conducting silica gel, a copper pipe bearing a main loop refrigerant is buried in the heat dissipation plate, and finally the heat is taken away by the refrigerant in the copper pipe. However, the structure is limited by the use of copper tubes and heat-conducting silica gel, and the cost and the process complexity (such as the length of a copper tube circuitous tube pass) are considered, so that the radiator has the defects of uneven heat dissipation, poor heat dissipation effect and higher manufacturing cost.

Based on the defects of the prior art, the applicant firstly submits a patent application with the publication number of "CN 109640601A" and the invention and creation name of a radiator cooled by a medium, an air-conditioning frequency converter and electronic equipment with the radiator; in the scheme, a medium heat exchange channel is directly formed in the radiator shell and forms a whole heat exchange medium path together with the cooling medium inlet and the cooling medium outlet, and when the radiator is used, the cooling medium flows into the heat exchange medium heat exchange channel to take heat out of the radiator. Compared with the scheme that the medium channel is formed by the copper pipe in the traditional scheme, the scheme omits the copper pipe and the heat conduction silica gel which must be adopted, and the cost is reduced. And, compared with the contrast, the medium heat transfer passageway that constitutes in this scheme can evenly distributed inside whole radiator shell, and need not by how much of copper pipe return circuit to prescribe a limit to, so can cover whole heat transfer region comprehensively, promote the heat transfer effect and guarantee that the heat transfer is even. However, in the radiator structure defined in the prior application, the cooling medium defined by the medium heat exchange channel flows unidirectionally from top to bottom or from left to right; the applicant has further developed a heat sink providing a divergent flow path.

In addition, in practice, the air-conditioning frequency converter or the electronic equipment has the advantage that in the heat dissipation process, the heat radiation effect of the edge of the equipment is better than that of the middle part due to the fact that the heat radiation effect of the edge of the equipment is better. In the prior application scheme, the medium heat exchange channel in the radiator shell flows from one side edge to the other side edge, so that the temperature difference of the inflow end is larger, and the radiating effect is better; the outflow end is superior to the temperature rise of the cooling medium, so that the heat exchange effect is reduced; and as just mentioned, the middle part has a poor heat dissipation effect compared with the problem of poor natural heat dissipation effect, and the heat dissipation effect is also poor compared with the two sides. Therefore, when the whole equipment is used, the heat dissipation of each area is not uniform, so that the improvement is urgently needed.
