Description

A kind of ErNi heat exchange material
Technical field
The present invention relates to heat exchange material and technology of preparing thereof, be specifically related to a kind of ErNi heat exchange material.
Background technology
Heat exchange material has broad application prospects on refrigerator, and it mainly becomes based on the magnetic entropy of magneticsubstance the magnetothermal effect brought out and works.In actual applications, for ensureing the heat exchange coefficient between magnetic heat exchange material and heat transferring medium, be usually processed into tiny irregular particle or spheroidal particle use.For intermetallic compound kind magnetic heat exchange material, atomizing type can be adopted to be processed into spheroidal particle.
The current main mode adopting the rear fragmentation of block sintering or powder granulation, becomes the particle of suitable size by oxide compound or the materials processing of oxysulfide class magnetic heat exchange.But, the particle obtained mostly is irregular particle, and with sharp-pointed corner, also need further sintering processes, and, also there is particle shape and be difficult to control in this method, the problems such as the density of particle, intensity and surfaceness are poor, cause the in use very easily efflorescence of heat exchange material particle, cause heat transferring medium resistance to flow to increase and heat exchanger effectiveness such as sharply to reduce at the bad phenomenon, the refrigeration capacity of refrigerator is declined, and work-ing life shortens.
In view of the defect existed in above prior art, be necessary existing apparatus to improve further, make it have more standby practicality, could realistic service condition.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of ErNi heat exchange material.
The present invention takes following technical scheme to realize: a kind of ErNi heat exchange material, and employing Graphite Powder 99 is base-material, and ErNi is major ingredient, and the raw material that auxiliary material comprises following parts by weight is prepared from:
