Abstract
The invention discloses a solenoid coil which is used for the solenoid valve of a refrigerating system, comprising a coil part and a magnetizer sheathed out of the coil part, wherein the coil part comprises a skeleton, an enamelled wire winding coiled on the skeleton, an encapsulated layer and a containing part, the encapsulated layer is coated out of the skeleton and the enamelled wire winding, and the containing part is used for containing a circuit board connected with the winding. The invention is provided with a defect part between the encapsulated layer outside the winding and the containing part of the containing circuit board by the coil part so as to effectively cut off the impact on the circuit board by the heating of the coil winding; meanwhile, the invention adds the heat dissipating area while being electrified to work, lowers coil temperature rise, prolongs the service life of the solenoid coil, shortens the shaping cooling time of the solenoid coil and improves the production efficiency of the solenoid coil.
Description
technical field [0001] The invention relates to the technical field of refrigeration control, in particular to an electromagnetic coil for an electromagnetic valve for controlling on-off of refrigerant, which is usually used in high-temperature and high-humidity environments of a refrigeration cycle. Background technique [0002] At present, various solenoid valves are widely used as automatic control components in the refrigeration system, and the electromagnetic coil and the valve body work together to control the on-off of the refrigerant in the refrigeration system. [0003] Existing schemes are structured like figure 1 As shown, an electromagnetic coil for a solenoid valve used for fluid control in a refrigeration system includes a skeleton and an enameled wire winding wound on the skeleton; the skeleton includes a winding core and a pair of parallel flanges arranged at both ends of the winding core portion, thereby forming a winding portion of the winding between the ...
