Abstract

The invention involves the technical field of electric relay, in particular to an electric relay with thermal structure, the electric relay with thermal structure comprises a first shell and a second shell, wherein an opening is formed on the top of the first shell and matched to install the second shell, the inside of which is matched to install an electric fan, a plurality of fixing plates are mounted on the outside of the second shell, the bottom of the fixing plates are equipped with external thread tubes, the bottom ends of which are inserted with support rods, the bottom ends of the support rods are installed on the upper surface of the first shell, a plurality of chutes are formed on the sides of the support rods which are sleeved with internal thread tubes, one ends of the internal threaded tubes are screwed to external threaded tubes, and ring pieces are arranged below the internal threaded tubes. The electric relay has the advantages of simple structure and convenient use, not only for dissipating the heat inside the relay, thereby prolonging service life of the relay, but also facilitating the disassembly and installation of the second shell and the first shell.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a relay with a heat dissipation structure. Background technique [0002] Solid state relays are non-contact switches composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. Isolation device is used to realize the isolation of control terminal and load terminal. The input terminal of the solid-state relay uses a small control signal to directly drive the high-current load. The solid-state relay in the prior art includes the housing and the relay components in the housing. In order to meet the requirements of the equipment, the solid-state relay often needs to be installed in a high-temperature working environment. Under the environment, working for a long time will reduce the life of the solid state relay. Contents of the invention [0003] The object of the present invention is to solve the shortcoming that the service life of the...
