Description

technical field [0001] The invention relates to the technical field of capacitor production, in particular to a circulating refrigeration device of a cooling device for film capacitor production. Background technique [0002] Film capacitor (Film Capacitor) is also called plastic film capacitor (Plastic Film Capacitor). It uses plastic film as the dielectric. [0003] Film capacitors are excellent capacitors due to their many excellent characteristics. Its main characteristics are as follows: non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and low dielectric loss. Based on the above advantages, film capacitors are widely used in analog circuits. Especially in the part where the signals are cross-connected, capacitors with good frequency characteristics and extremely low dielectric loss must be used to ensure that the signal will not be distorted when it is transmitted. [0004] Its structure is the same as that of...

Problems solved by technology

[0006] In the production and heat dissipation process of film capacitors, the cold storage agent is added to the cold storage box to cool down. On the one hand, the cooling effect is limited, and on the other hand, excessive use of cold storage agent will cause serious environmental pollution.
