Abstract

The invention discloses a low-temperature-rise micro heat dissipation flow channel magnetic core. The magnetic core comprises a base, side columns and a middle column, a non-through middle column groove corresponding to the middle column is formed in the top of the middle of the base; the middle column groove is a horn mouth groove; a through connecting column hole is downwards formed in the middle of the middle column groove; a through connecting column hole corresponding to the connecting column hole is also formed in the middle of the middle column; matched connecting columns are inserted into the two connecting column holes, three-way heat conduction grooves which are communicated with the middle column groove and penetrate through the base are formed in the inner sides of the two sidecolumns on the base, a plurality of heat dissipation micro grooves are formed in the bottom of the middle column groove, one end of each heat dissipation micro groove is communicated with the corresponding connecting column hole, and the other end of each heat dissipation micro groove extends to the position below the corresponding three-way heat conduction groove. According to the low-temperature-rise micro heat dissipation flow channel magnetic core, the middle column is detachably arranged, the uniformity of the density of the machined core column can be guaranteed, and winding is facilitated; the micro-channels are formed in the middle column and the base, and heat dissipation can be well achieved under the condition that winding and magnetic flux of the magnetic core are not affected.

Description

technical field [0001] The invention relates to the technical field of magnetic cores, in particular to a magnetic core with low-temperature rise and micro-radiation channel. Background technique [0002] The magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. In the prior art, ferrite magnetic cores are used in coils and transformers of various electronic devices. [0003] The magnetic core will generate a lot of heat during use, so the heat dissipation capacity is one of the important factors affecting the performance of the magnetic core. The traditional E-type magnetic core has a relatively better heat dissipation space than other types of magnetic cores, but the heat dissipation of the center column is still Will be affected by the side columns. [0004] In addition, due to the difference in surface area between the center column and the side column, the pressure on the center column and the side column is different during the pres...
