Description
Technical field
Field, more particularly to a kind of cooling system of electrical equipment are manufactured the present invention relates to power electronic equipment.
Background technology
For electrical equipment, the heating element of key is usually present, particularly its nucleus module caloric value is huge, needs
Single cooling system is designed, the heat of inside electric appliance is shed as early as possible, it is ensured that the reliable and stable operation of equipment.Existing skill
Mode in art frequently with forced air cooling is radiated, and often there is blower fan short life under adverse circumstances, and fault rate is high, blower fan dimension
Shield is frequent, the problems such as air channel is easily blocked.And the cooling system of forced air cooling is often radiated just for nucleus module, and
The heat dissipation problem of other heater members of inside electric appliance cannot be solved, and can only be radiated by product case.
Therefore, which kind of mode is forced air cooling mode is replaced using, while can also solve other heating elements well
Heat dissipation problem is the technical problem of current those skilled in the art's urgent need to resolve.
The content of the invention
The present invention is directed to the problems of cooling system in current electrical equipment, it is proposed that a kind of radiating of electrical equipment
System, the cooling system is radiated by the way of natural heat dissipation to the key componentses in equipment and whole machine, effective to protect
The heat dissipation problem of heating element and whole machine is demonstrate,proved, while having evaded problem present in forced air cooling system, due to the system
Blower-free, so effectively reducing the cost of power-converting device, improves the reliability of system.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of cooling system of electrical equipment, including electrical appliance enclosure 2 and be separately positioned on after electrical appliance enclosure 2
The main radiator 1 and secondary radiator 3 of side and front side；The electrical appliance enclosure 2 is without front panel and rear board；The main radiator
It is provided with and is outwardly radiated by the radiation tooth of main radiator 1 on the substrate of 1 radiation tooth and inner side including outside, the substrate
Electrical equipment various heating elements 4, when the main radiator 1 and electrical appliance enclosure 2 are installed, substrate-side is arranged on electricity
The inner side of gas device housings 2, gear piece side is arranged on the outside of electrical appliance enclosure 2, and main radiator 1 serves as electrical appliance enclosure 2
Rear board；There is radiation tooth inside and outside the secondary radiator 3, installed in the front side of casing, serve as before electrical equipment
The heat for remaining in inside electric appliance is mainly transmitted to and electrically set by panel, secondary radiator 3 inside electrical appliance enclosure 2
The standby outside of shell 2, makes the part without Nvidia custom thermal system NVIDIA in electrical equipment be radiated, it is ensured that whole system can radiate.
The main radiator 1 and the air channel of secondary radiator 3 and the gravity direction of electrical equipment are consistent, by heat
Air buoyancy lift enhancing air velocity, can heat radiation device heat loss through convection effect.
The surface of the main radiator 1 and secondary radiator 3 has carried out anodized, can improve material surface radiation
Coefficient, so that the heat loss through radiation ability of heat radiation device.
The surfaces externally and internally of the electrical appliance enclosure 2 has carried out anodized, improves material surface radiation coefficient, no
But the ability that casing absorbs cabinet inside heat by radiant heat transfer is improved, casing is also improved by radiant heat transfer outwardly
The ability of radiating.
The secondary radiator 3 is by heat loss through convection and heat loss through radiation mode by high temperature air and nothing in electrical appliance enclosure 2
Heat produced by the heater members that method is radiated by main radiator 1 is dispersed into external environment, so as to play reduction temperature
Effect.
There is radiation tooth on two sides inside and outside the secondary radiator, on the one hand adds the area of heat convection, on the other hand
The receptor area of hot-air and heater members radiant heat transfer in secondary radiator receiving pit body is increased, so as to enhance secondary radiator
Heat-sinking capability.
The design for the cooling system that the present invention passes through electrical equipment and the measure taken, whole system is without forced air cooling
The cooling requirements of device interior can be achieved, whole machine cost greatly reduces in this method, while improving the reliability of system.

Fig. 1 is the overall structure figure of electrical equipment cooling system of the present invention.
Fig. 2 is the cut-away view of electrical equipment cooling system of the present invention.
Fig. 3 is the flow graph of thermal current in secondary radiator.
Embodiment
As shown in figure 1, the cooling system of the electrical equipment includes electrical appliance enclosure 2, main radiator 1 and secondary radiator 3.
The main radiator 1 and secondary radiator 3 are separately mounted to the front and rear both sides of electrical appliance enclosure 2, and electrical appliance enclosure 2 is clipped in
Centre, and in the space of casing internal one sealing of formation.
As shown in Fig. 2 electrical appliance enclosure 2 is without front and back panel, only the four of side face, the main radiator of electrical equipment
There is radiation tooth in 1 outside, and inner side is provided with the various heating member devices in power equipment without radiation tooth on substrate, and substrate
Part 4, the heating element 4 is outwardly radiated by main radiator 1, when main radiator 1 is installed with electrical appliance enclosure 2, substrate
Side is arranged on the inner side of electrical appliance enclosure 2, and gear piece side is arranged on the outside of electrical appliance enclosure 2, and whole main radiator 1 is installed
The rear board of electrical appliance enclosure 2 is acted as afterwards；There is radiation tooth on two sides inside and outside the secondary radiator 3 of electrical equipment, installed in machine
