Reactor

Abstract

The invention discloses a reactor. The reactor comprises an E-shaped iron core (10), insulating parts (20), a winding component (30) and an I-shaped iron core (40), wherein the E-shaped iron core (10)comprises a center pillar (11) and two side pillars (12) arranged on the both sides of the center pillar (11) in a spaced manner, and an accommodating part is formed between the side pillars (12) andthe center pillar (11); the winding component (30) is covered with the insulating part (20) and is placed in the accommodating part of the E-shaped iron core (10); and the I-shaped iron core (40) issupported on the top ends of the two side pillars (12) of the E-shaped iron core (10) to seal the winding component (30) into the accommodating part; and heat dissipation structures are arranged on the two side pillars (12) of the E-shaped iron core (10). The reactor disclosed by the invention has high safety performance and good sealing performance, and can be used in environments such as humidity and water droplets, and the E-shaped iron core and the I-shaped iron core can realize various air gap combination forms, thereby reducing the development cost and facilitating the mass production.

Description

technical field [0001] The present invention relates to the technical field of reactors, in particular to a reactor. Background technique [0002] With the increasingly fierce market competition, the design and manufacture of reactors are continuously optimized, and the requirements for cost and performance are also continuously improved. At present, the existing reactors generally have the following problems: 1. Reactors are used in household appliances because they are close to the control circuit board, and the operating temperature is high, so they need to use a better heat dissipation structure to adapt to the working environment; 2. In washing machines, etc. For product application, the reactor usually uses the immersion method, and its surface is covered with insulating paint, but this will lead to corrosion, poor appearance, and poor waterproof performance; 3. The air gap between the existing EI iron cores is a fixed value. When there is a gap, the mold can only be ...

Problems solved by technology

At present, the existing reactors generally have the following problems: 1. Reactors are used in household appliances because they are close to the control circuit board, and the operating temperature is high, so they need to use a better heat dissipation structure to adapt to the working environment; 2. In washing machines, etc. For product application, the reactor usually uses the immersion method, and its surface is covered with insulating paint, but this will lead to corrosion, poor appearance, and poor waterproof performance; 3. The air gap between the existing EI iron cores is a fixed value. Only new molds can be opened when there is a gap, which leads to the problem of increasing development costs
