Problems solved by technology

At present, the commonly used high-power inductors mostly use forced convection cooling or natural convection cooling. In order to ensure heat dissipation efficiency, they are usually large in size and have a single function, which is not conducive to the use in confined spaces, and cannot meet the further improvement of the power density of power electronic conversion equipment. needs

Abstract

The invention discloses an installation method of a water-cooling electric induction module installed on a printed wiring board and application thereof. The water-cooling electric induction module comprises a pedestal and an upper cover which are oppositely arranged and correspondingly fastened to form a hollow cavity, as well as a resin potting inductor arranged in the hollow cavity, end covers arranged at two ends of the hollow cavity and a water-cooling pipe, wherein two ends of the resin potting inductor are respectively provided with inductance outgoing lines which are pierced out of thehollow cavity, two sides of the pedestal are integrally and symmetrically provided with U-shaped grooves with upward openings, and the water-cooling pipe is fixedly arranged in the U-shaped grooves. The water-cooling electric induction module is used for integrating together the inductor, the water-cooling pipe and a cooling fin, and good heat dissipation efficiency is guaranteed when the volume of the water-cooling electric induction module is shrunk; the water-cooling electric induction module can be installed on the printed wiring board (PCB), thereby meeting the usage requirement of high power density power electronic conversion equipment; a main body is divided into two parts, i.e., a pedestal and an upper cover, the disassembly and assembly are convenient, and the resin potting inductor is convenient to maintain and replace; during use, the use of multiple water-cooling electric induction modules connected in series can be realized, thereby meeting requirement of high power.

Description

technical field [0001] The invention relates to a power water-cooled inductance used in the field of power electronics, in particular to a method for installing a high-power water-cooled inductance module installed on a printed circuit board (hereinafter referred to as PCB) and its application. Background technique [0002] Inductor is an electromagnetic induction element wound with insulated wires. It can convert electrical energy into magnetic energy and store it. It is one of the commonly used components in electronic circuits. Its structure is similar to that of a transformer, but it has only one winding. The main function is to isolate and filter AC signals or form a resonant circuit with capacitors and resistors. In the field of power electronics, it is often used in circuits such as boosting, stepping down, power factor correction, and inverter output filtering. At present, the commonly used high-power inductors mostly use forced convection cooling or natural convecti...
