AI Technical Summary

Technical Problem

When the existing solid-state ejection refrigeration and heating devices apply stress to the drive device, it is easy to cause dislocation of the solid-state ejection material plate and blockage of the flow chamber, resulting in a decrease in thermal conductivity.

Method used

A heat recovery device is designed, and the inner wall of the sleeve is provided with a protrusion, which extends into the groove of the solid-state ejection clamp material plate to form an elongated flow cavity, and a perforation is provided on the solid-state ejection clamp material plate to form a second flow cavity.

Benefits of technology

By fixing the position of the solid-state elastic clamp material plate, dislocation is avoided, and an elongated flow chamber with small flow resistance is formed, the flow rate and thermal conductivity of the thermal fluid are improved, and the thermal conductivity efficiency is further improved by increasing the contact area.

Abstract

The invention provides a heat regeneration device and a refrigerating and heating device, the heat regeneration device comprises a sleeve and solid elastic clamping material plates, the inner wall of the sleeve comprises protrusions, the multiple solid elastic clamping material plates are stacked in the sleeve, each solid elastic clamping material plate comprises a groove, a space formed by stacking the multiple grooves is used for containing the protrusions on the inner wall of the sleeve, and the protrusions are arranged on the inner wall of the sleeve. After the grooves are stacked, gaps between the grooves and the protrusions form flow cavities for heat conduction fluid to flow through. The protrusions are arranged on the inner wall of the sleeve and extend into the grooves of the solid elastic clamping material plate, the position of the solid elastic clamping material plate can be fixed, the flow resistance of gaps between the grooves and the protrusions is small, and the heat conduction efficiency is improved. In addition, the contact area between the flow cavity and the solid elastic clamping material is large, and the heat conduction efficiency of the heat conduction fluid is further improved.
