Water-circulating cooling device for instant electromagnetic water heater

Abstract

The invention discloses a water-circulating cooling device for an instant electromagnetic water heater. The invention aims to overcome the defects that a high-power electronic element is not radiated directly, and the radiating effect is not obvious, so the working performance of the electronic element is low, the electronic element is easily damaged, the occupation space in a shell is larger, and the utilization ratio is low in the prior art. The key points of the technical scheme are that: the invention is characterized by a water-cooling type radiator fixedly mounted on the board surface of a main circuit board in the shell of the water heater; the radiator consists of a metal radiating substrate with a polygonal section and a cold water pipeline arranged in the substrate; a water inlet and a water outlet of the cold water pipeline stretch out of the metal radiating substrate; the metal radiating substrate reclines on the main circuit board by a side surface; radiating surfaces of a rectifier, a power switching device and a capacitor on the main circuit board are attached to other side surfaces of the metal radiating substrate; and the water inlet of the cold water pipeline is connected to a water inlet pipe of the water heater or a cold water circulating passage in the water heater, and a water outlet pipe of the cold water pipeline is connected to the water inlet pipe of an electromagnetic heater of the water heater.

Description

technical field [0001] The invention relates to working parts of hot water supply equipment used in civil, industrial or other fields, in particular to a water circulation cooling device for an instant electromagnetic water heater. It is suitable for instantaneous electromagnetic hot water equipment with large water consumption, such as bathroom water heaters. Background technique [0002] The instant electromagnetic water heater is an electric water heater with good safety and high thermal efficiency. The electromagnetic induction principle of the instant electromagnetic water heater is to convert the 50-60HZ alternating current into direct current, and then convert the direct current into a high-variable current with a frequency of 20-25KHZ through the control circuit, and use the high-variable current to generate a high-variable magnetic field through the coil. When the magnetic field lines inside the magnetic field pass through the metal container, countless small eddy ...
