The solid-state relay with a novel heat dissipating structure has a good heat dissipating effect and an effectively-prolonged service life, and comprises a cylindrical relay body and a heat dissipater. The heat dissipater comprises a bottom plate, a side plate, heat dissipating fins, a flow deflector, and a fan which are mutually connected to become one body. The bottom plate is abutted against and fixed on the bottom of the relay body while the side plate is abutted against and fixed on the side of the relay body. Multiple heat dissipating fins are provided. The heat dissipating fins are fixed vertically and are distributed on the outer side surfaces of the side plate symmetrically. The flow deflector is fixed on the outer sides of the heat dissipating fins in a surrounding manner. The distance between the top of the flow deflector and the side plate is more than that between the bottom of the flow deflector and the side plate. Multiple flow guiding holes are symmetrically disposed on the bottom of the flow deflector. The inner openings of the flow guiding holes are inclined upwardly. The fan is arranged over the relay body and is fixed on the inner side of the top of the flow deflector through supporting rods around the fan. The heat dissipater is a cooper heat dissipater.

Background technology
As everyone knows, solid-state relay is a kind of contactless switching device being comprised of microelectronic circuit, discrete electronic device, power electronic power device, is widely used in circuit control; Owing to can producing larger heat in use procedure, existing solid-state relay, generally include relay body and radiator, radiator is the radiating bottom plate of metal material, relay body is arranged on radiating bottom plate, yet this radiator is difficult to effectively guarantee radiating effect, after long-term use, easily there is the intrinsic electronic component Yin Gaowen of relay and impaired problem, and then affect the useful life of solid-state relay.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of radiating effect better, effectively improves the solid-state relay of the radiating structure in useful life.
The solid-state relay of radiating structure of the present utility model, the relay body and the radiator that comprise column, described radiator comprises the base plate that interconnects and be structure as a whole, side plate, fin, baffler and fan, described base plate and side plate are fitted respectively and are fixed on bottom and the side of described relay body, described fin is a plurality of, the lateral surface of described side plate is vertically fixed and be symmetrically distributed in to described fin, described baffler is around the outside that is fixed on described fin, the spacing of described baffler top and described side plate is greater than the spacing of baffler bottom and side plate, the bottom of described baffler is also symmetrically arranged with a plurality of diversion stomatals, and the inner side opening part of described diversion stomatal is inclined upwardly, described fan is positioned at the top of described relay body, and the surrounding of described fan is fixed on the medial surface at described baffler top by support bar, described radiator is copper radiator.
Further, the lateral surface of described side plate is also provided with water conservancy diversion ridge, and described water conservancy diversion ridge and described fin are parallel to each other.
Compared with prior art the beneficial effects of the utility model are: the relay body and the radiator that comprise column, radiator comprises the base plate that interconnects and be structure as a whole, side plate, fin, baffler and fan, base plate and side plate are fitted respectively and are fixed on bottom and the side of relay body, fin is a plurality of, the lateral surface of side plate is vertically fixed and be symmetrically distributed in to fin, baffler is around the outside that is fixed on fin, the spacing of baffler top and side plate is greater than the spacing of baffler bottom and side plate, the bottom of baffler is also symmetrically arranged with a plurality of diversion stomatals, and the inner side opening part of diversion stomatal is inclined upwardly, fan is positioned at the top of relay body, and the surrounding of fan is fixed on the medial surface at baffler top by support bar, radiator is copper radiator, like this, the heat that relay body produces can pass through base plate, side plate, fin and baffler mutually conduct and realize multilayer and dispel the heat simultaneously, effectively increased area of dissipation, and side plate, in the heat radiation cavity that fin and baffler surround, heat between air and radiator is fully exchanged, and negative pressure is formed on the bottom at baffler in hot air rising process, under the effect of negative pressure, cold air enters from bottom opening place and diversion stomatal, effect even without radiator fan, radiator inside also can form the radiating airflow of self-loopa, effectively improved radiating effect, therefore here, fan does not have the top that is arranged on relay body totally-enclosedly, to avoid the barrier effect of fan blade to radiating airflow, air draft effect when the effect of fan is to turn round more, can also form certain negative pressure simultaneously at the top of heat-conducting plate, accelerate the rate of climb of radiating airflow, thereby the slow-speed of revolution and low power fan can complete thermolysis.
