Description
Technical field
The present invention relates to power electronic equipment and manufacture field, particularly relate to a kind of cooling system of electric equipment.
Background technology
For electric equipment, generally all there is crucial heating element, particularly its nucleus module caloric value is huge, need design independent cooling system, is shed as early as possible by the heat of inside electric appliance, ensures the reliable and stable operation of equipment.In prior art, the normal mode of forced air cooling that adopts is dispelled the heat, and under often there are adverse circumstances, fan life is short, and failure rate is high, and blower fan is safeguarded frequent, and air channel such as easily to block at the problem.And the cooling system of forced air cooling often only dispels the heat for nucleus module, and the heat dissipation problem of other heater members of inside electric appliance can not get solving, and can only be dispelled the heat by product case.
Therefore, adopt which kind of mode to replace forced air cooling mode, the heat dissipation problem that simultaneously also well can solve other heating elements is technical problems that current those skilled in the art need solution badly.
Summary of the invention
The present invention is directed to the problem existing for cooling system in current electric equipment, propose a kind of cooling system of electric equipment, this cooling system adopts the mode of natural heat dissipation to dispel the heat to the key components in equipment and complete machine, effectively ensure that the heat dissipation problem of heating element and complete machine, evaded Problems existing in forced air cooling system simultaneously, due to this system Blower-free, so effectively reduce the cost of power-converting device, improve the reliability of system.
For achieving the above object, the present invention adopts following technical scheme:
A cooling system for electric equipment, comprises electrical appliance enclosure 2 and to be separately positioned on rear side of electrical appliance enclosure 2 and the main radiator 1 of front side and secondary radiator 3; Described electrical appliance enclosure 2 is without front panel and rear board; Described main radiator 1 comprises the radiation tooth in outside and the substrate of inner side, described substrate is provided with the various heating elements 4 of the electric equipment outwardly dispelled the heat by the radiation tooth of main radiator 1, when described main radiator 1 is installed with electrical appliance enclosure 2, substrate-side is arranged on the inner side of electrical appliance enclosure 2, gear piece side is arranged on the outside of electrical appliance enclosure 2, and main radiator 1 serves as the rear board of electrical appliance enclosure 2; All there is radiation tooth the inside and outside both sides of described secondary radiator 3, be arranged on the front side of casing, serve as the front panel of electric equipment, secondary radiator 3 mainly by remain in inside electric appliance heat from electrical appliance enclosure 2 conducted inside to electrical appliance enclosure 2 outside, parts without Nvidia custom thermal system NVIDIA in electric equipment are dispelled the heat, ensures that whole system all can be dispelled the heat.
Described main radiator 1 and the air channel of secondary radiator 3 and the gravity direction of electric equipment are consistent, and the buoyancy lift by hot-air strengthens air velocity, can the heat loss through convection effect of heat radiation device.
Anodized has all been carried out in the surface of described main radiator 1 and secondary radiator 3, can improve material surface radiation coefficient, thus the heat loss through radiation ability of heat radiation device.
The surfaces externally and internally of described electrical appliance enclosure 2 has carried out anodized, improves material surface radiation coefficient, not only increases casing absorbs cabinet internal heat ability by radiant heat transfer, also improves the ability that casing is outwardly dispelled the heat by radiant heat transfer.
The heat that high temperature air in electrical appliance enclosure 2 and the heater members that cannot be dispelled the heat by main radiator 1 are produced is dispersed in external environment by heat loss through convection and heat loss through radiation mode by described secondary radiator 3, thus plays the effect reducing temperature.
Inside and outside described secondary radiator, all there is radiation tooth on two sides, adds the area of heat convection on the one hand, also increases the receptor area that secondary radiator accepts hot-air and heater members radiant heat transfer in casing on the other hand, thus enhances the heat-sinking capability of secondary radiator.
The present invention is by the design of the cooling system of electric equipment and the measure taked, and whole system can realize the cooling requirements of device interior without the need to forced air cooling, and the method greatly reduces complete machine cost, improves the reliability of system simultaneously.
