Description

Air-cooled solid-state relay
Technical field
The utility model relates to a kind of relay, is specifically related to a kind of air-cooled solid-state relay.
background technology
As everyone knows, solid-state relay is a kind of contactless switching device being made up of microelectronic circuit, discrete electronic device, power electronic power device, is widely used in circuit control; 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, this radiator is difficult to effectively ensure radiating effect, after long-term use, easily occurs the intrinsic electronic component Yin Gaowen of relay and impaired problem, especially some high power relays, the impaired probability of high temperature is higher, and then affects the useful life of solid-state relay.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of simple and reasonable for structure, good heat dissipation effect, the air-cooled solid-state relay of long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: air-cooled solid-state relay, comprise: components and parts, described components and parts are arranged in closed shell, components and parts terminals are positioned at the outside of closed shell, are provided with multiple thermal-collecting tubes between described closed shell and components and parts, and the top of described closed shell has exhaust outlet, the bottom of closed shell has air entry, and top, the bottom of thermal-collecting tube are connected with exhaust outlet and air entry respectively.
Preferably, the top of described closed shell is provided with block, and the bottom of closed shell is provided with bellows, and the top of described block is provided with ventilating fan, and multiple air inlets are installed on bellows.
Preferably, described thermal-collecting tube is copper pipe.
The utility model is simple and reasonable for structure, and good heat dissipation effect adopts and in closed shell, directly installs multiple thermal-collecting tubes additional, the heat producing for absorbing components and parts, and the two ends of thermal-collecting tube are communicated with atmosphere, make the hot-air automatic cycle heat radiation in thermal-collecting tube.
For better radiating effect, install ventilating fan additional at the top of closed shell, the bottom of closed shell installs bellows additional, and the hot-air in thermal-collecting tube is forced to air draft refrigeration, greatly reduces the heat producing in closed shell, the useful life of the components and parts of raising.
Brief description of the drawings
Fig. 1 is the structural representation of the air-cooled solid-state relay of the utility model.
In figure: 1 is components and parts, 2 is closed shell, and 3 is thermal-collecting tube, and 4 is exhaust outlet, and 5 is air entry, and 6 is block, and 7 is bellows, and 8 is ventilating fan, and 9 is air inlet.
Embodiment
The specific embodiment of the utility model being done below in conjunction with accompanying drawing is described further.
As shown in Figure 1, air-cooled solid-state relay, comprise: components and parts 1, described components and parts 1 are arranged in closed shell 2, components and parts 1 terminals are positioned at the outside of closed shell 2, closed shell 2 adopts insulating material to support, between closed shell 2 and components and parts 1, be provided with multiple thermal-collecting tubes 3, the general copper pipe that adopts of thermal-collecting tube 3, the top of closed shell 2 has exhaust outlet 4, the bottom of closed shell 2 has air entry 5, and top, the bottom of thermal-collecting tube 3 are connected with exhaust outlet 4 and air entry 5 respectively, and exhaust outlet 4 and air entry 5 are all connected with atmosphere.In the time that components and parts 1 carry out work, the heat of generation passes to thermal-collecting tube like this, and the air in thermal-collecting tube is heated and moves up, thereby forms the circulation of air automatic flowing, good heat dissipation effect.
In order better to strengthen the radiating effect of components and parts, block 6 is installed at top at closed shell 2, bellows 7 are installed in bottom at closed shell 2, and the top of block 6 is provided with ventilating fan 8, and multiple air inlets 9 are installed on bellows 7, air entry 5 is connected with bellows 7, air inlet 9 is connected with atmosphere, in the time that components and parts caloric value is larger, can adopt ventilating fan 8 to carry out air blast cooling but to thermal-collecting tube 3 like this, greatly strengthened the radiating effect of thermal-collecting tube 3, also greatly improve the useful life of components and parts.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken possessing those of ordinary skill in the art; the various variations that can also make under the prerequisite that does not depart from the utility model aim, also should be considered as protection range of the present utility model.
