Abstract

The invention discloses a heat exchanger of a Stirling engine. The heat exchanger of the Stirling engine comprises a heat exchanger shell. The heat exchanger shell is of a cylindrical structure; globoids are arranged in the heat exchanger shell; the globoids are full of the interior of the heat exchanger shell; the globoids are pairwise contacted and connected mutually to form a heat exchanger body; the inner wall of the heat exchanger body is fixedly connected with the outer side face of the heat exchanger body; the globoids can be made of stainless steel or copper; the heat exchanger body is manufactured by performing hot press molding on the globoids. Therefore, the heat exchanger of the Stirling engine disclosed by the invention has the following beneficial effects: the heat exchanger body is very low in manufacturing and processing cost; the contact area between gas and the globoids in the heat exchanger body is very large, so that the heat exchange area is large, and the heat exchange efficiency is very high; when the gas passes the heat exchanger body, an edge effect does not exist, so that the edge heat loss is reduced, and the heat exchange efficiency is improved; gas flow flowing through the heat exchanger body is uniform and stable and is fully contacted with the surfaces of the globoids, so that the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to a Stirling engine, in particular to a Stirling engine heat exchanger. Background technique [0002] The heat exchanger is an important part of the Stirling engine. Heating, cooling, and heat recovery all need to pass through the heat exchanger. The Stirling engine has a high conversion efficiency between thermal energy and mechanical energy, and the heat exchange between thermal energy and mechanical energy The efficiency of the heat exchanger mainly depends on the heat exchange efficiency of the heat exchanger. At present, tube heat exchangers, fin heat exchangers or wire mesh heat exchangers are generally used for heating of Stirling engines, water-cooled heat exchangers are mainly used for cooling, and regenerative heat exchangers are used for heat recovery. Comprehensively balancing the contradiction between the flow volume of the heat exchanger, the flow resistance loss of the working fluid, and the heat exchange capacity...
