Radiation-proof casing for synchronous rectification power supply

Abstract

The invention provides a radiation-proof shell for a synchronous rectification power supply, which includes a left shell and a right shell, an electromagnetic radiation-proof ring, an electromagnetic-radiation-proof layer, a neutron-radiation-proof ring, a neutron-radiation-proof layer, and a shell cover. Through the design of the left shell and the right shell, the rectifier power supply can be assembled conveniently, and the sealing of the shell can be ensured more through the use of rubber pads; the present invention uses epoxy resin, dicyandiamide, acetone, conductive carbon powder, carbon fiber, Aluminum powder is the raw material of the anti-electromagnetic radiation layer. After mixing the raw materials of the anti-electromagnetic radiation layer evenly, dip-coat both sides of the glass fiber cloth with a dipping machine, and after drying at 150°C for 30 minutes, the anti-electromagnetic radiation layer is prepared. layer, which solves the fundamental problem of anti-electromagnetic radiation. By adding rectorite, it has solidified nuclides, is not easy to flocculate, and is anti-cracking. It is an ideal radiation protection material and has the functions of preventing neutrons, X-rays, and gamma rays.

Description

technical field [0001] The invention relates to the technical field of rectifying power supplies, in particular to a radiation-proof housing for synchronous rectifying power supplies. Background technique [0002] Anti-electromagnetic radiation is to cut off the interference of power lines and magnetic lines of force. Anti-electromagnetic radiation is to reflect electromagnetic waves and let electromagnetic waves form "eddy current loss" in the protective material to attenuate electromagnetic waves. Generally, anti-static conductor materials and metal materials are added to the protective materials to prevent high-frequency and low-frequency electromagnetic waves from passing through, and to allow electromagnetic waves to reflect at the interface of different materials to eliminate the influence of electromagnetic waves; the existing rectifier power supply protection shell, basically The use of metal radiation-proof shells has the following problems: First, the metal protec...

Problems solved by technology

Generally, anti-static conductor materials and metal materials are added to the protective materials to prevent high-frequency and low-frequency electromagnetic waves from passing through, and to allow electromagnetic waves to reflect at the interface of different materials to eliminate the influence of electromagnetic waves; the existing rectifier power supply protection shell, basically The use of metal radiation-proof shells has the following problems: First, the metal protective shell is heavy and easily corroded. When it protects electromagnetic radiation, it needs sufficient thickness and consumes a lot of materials.

Secondly, metal radiation-proof shells cannot effectively protect against neutron radiation; at present, neutron radiation shielding materials mainly include two types: (1) synthetic materials, carbon-boron polyethylene, boron-containing epoxy resin, boron carbide, zirconium hydride etc. These materials have high cost and are not easy to form; (2) natural materials, such as barite, limonite, witherite and other large specific gravity minerals, use such materials to introduce steel forging to make the body weight too large, resulting in easy segregation, There are many problems such as easy cracking and poor durability. Limestone, colemanite, pumice, etc. are used as mineral admixtures, but the anti-neutron radiation effect is poor
