A NdFeB magnet with good heat resistance

Abstract

The invention discloses a neodymium iron boron magnet with good heat resistance. The neodymium iron boron magnet with good heat resistance comprises a heat dissipation box; an upper surface of the heat dissipation box is fixedly embedded with a symmetrical first pipe; an inner top wall of the heat dissipation box is provided with two sets of symmetrical sliding ports; a bearing rod is placed inside each group of sliding port; two sets of symmetrical sliding plates are placed above the heat dissipation box; the bottom end of each set of sliding plate runs through the sliding port and extends tothe inside of the heat dissipation box; the sides of each set of sliding plates that are close to each other are fixedly connected with first baffles; the inside of each set of sliding plates is fixed with a second through pipe; the left end of each set of bearing rod is fixedly connected to the inner side wall of the sliding port; and the right end of each set of bearing rod runs through the second through pipe and is fixedly connected to the inner side wall of the sliding port. The design of the neodymium iron boron magnet with good heat resistance is reasonable in structure, which can input a water source into a condensing pipe, realize the water injection into the condensing pipe, can recycle the water source, and can reinforce the magnet placed the heat dissipation box, thereby realizing the stability of the magnet.

Description

technical field [0001] The invention relates to the technical field of neodymium-iron-boron magnets, in particular to an neodymium-iron-boron magnet with good heat resistance. Background technique [0002] NdFeB magnets can be divided into bonded NdFeB magnets and sintered NdFeB magnets. Bonding is actually injection molding, while sintering is vacuumized and formed by high temperature heating. The permanent magnet with the strongest magnetic force is second only to the holmium magnet at absolute zero, but its magnetism is far stronger than all known permanent magnets at room temperature. [0003] At this stage, the temperature of NdFeB magnets is extremely unstable, and accidents often occur, causing troubles for personal safety. Conventional heat dissipation machines do not have fixation, which causes troubles for heat dissipation efficiency. For this reason, we propose a neodymium magnet with good heat resistance. Iron boron magnets to solve the above problems. Content...
