A magnetic working fluid packaging box for magnetic refrigeration cycle

Abstract

The invention discloses a packaging box for a magnetic working medium used for magnetic refrigeration circulation. The packaging box for the magnetic working medium used for magnetic refrigeration circulation comprises a rectangular shell with a cover plate, wherein a plurality of copper pipes used for containing the magnetic refrigeration working medium are fixedly arranged in the shell in parallel in the length direction, the two ends of each copper pipe are sealed, wing type bosses are arranged in the middle of the outer side of one long edge of the shell and in the middle of the outer side of the other long edge of the shell respectively, through holes matched with a guide rail are formed in the side faces of the wing type bosses, a first water inlet and a second water inlet which are communicated with an inner cavity of the shell are symmetrically formed in the two sides of the wing type boss in the middle of the first long edge of the shell, and a first water outlet and a second water outlet which are communicated with the inner cavity of the shell are symmetrically formed in the two ends of the other long edge of the shell. According to the packaging box for the magnetic working medium used for magnetic refrigeration circulation, the magnetic refrigeration working medium is sealed in the copper pipes so as to be prevented from being in direct contact with water, in this way, the degree of corrosion of the magnetic working medium is greatly reduced, and money for purchasing the magnetic refrigeration working medium is saved; meanwhile, heat dissipation is kept to a certain extent, water in a magnetic working medium box is optimized, and heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic refrigeration, in particular to a magnetic working fluid packaging box for a magnetic refrigeration cycle. Background technique [0002] In 1881, Warburg first observed the thermal effect of metallic iron in an external magnetic field, and in 1895, P. Langeriz discovered the magnetocaloric effect [1] In 1926, solid theoretical physicist P.Debye and physical chemist W.F.Giauque in 1927 respectively proposed the physical basis of paramagnetic salt refrigeration effect [2] , Magnetic refrigeration technology can be further developed. In 1976, Brown of the NASA Research Center used a reciprocating refrigeration device similar to the Ericsson cycle for the first time, using metal gadolinium as a magnetic working medium to obtain the success of a room temperature magnetic refrigerator [3] . In 1997, the AMES Laboratory of Iowa State University in the United States cooperated with NASA to develop the...
