Description

Technical Field

[0001] The utility model relates to the technical field of solid-state relays, in particular to a solid-state relay which is convenient for heat dissipation. Background Art

[0002] A solid-state relay is a new type of contactless switching device composed entirely of solid-state electronic components. It uses the switching characteristics of electronic components to achieve the purpose of connecting and disconnecting circuits without contact or sparks, so it is also called a "contactless switch". A solid-state relay is a four-terminal active device, two of which are input control terminals and the other two are output controlled terminals. It has both an amplifying driving function and an isolating function. Since the existing solid-state relays are well sealed, they are prone to overheating and causing internal components to malfunction or be damaged under long-term working conditions. In order to solve this problem, this application provides a solid-state relay that is easy to dissipate heat.

[0003] The existing Chinese utility model patent with application number CN202321757945.9 discloses a new type of high-efficiency heat dissipation integrated solid-state relay, including a solid-state relay body and a heat dissipation base. The heat dissipation base includes a heat dissipation frame. The side view of the heat dissipation frame is in the shape of a fishbone structure. The upper end of the heat dissipation frame is provided with a mounting plate, and the lower end of the heat dissipation frame is provided with a mounting base. The bottom surface of the solid-state relay body is fitted and mounted on the mounting plate. The top views of the solid-state relay body and the heat dissipation base are both rectangular. The solid-state relay body includes an outer shell, in which a printed control board is installed. The two ends of the printed control board are connected and installed with load output terminals, and the two load output terminals are respectively arranged at the two narrow sides of the solid-state relay body. The utility model is used to solve the problems of large size and poor heat dissipation effect of solid-state relays in the prior art; however, the existing patent has the following problems:

[0004] The above-mentioned new high-efficiency heat dissipation integrated solid-state relay can only dissipate heat passively through the heat dissipation frame in the shape of a fishbone structure, and cannot quickly conduct the heat generated by the solid-state relay. The heat dissipation efficiency is slow and it is not convenient for promotion and use. Utility Model Content
