The invention relates to the technical field of micro gas turbines, and discloses a heat exchanger and a micro gas turbine. The heat exchanger includes: an outer shell, an inner shell, and a plurality of spiral fans enveloped between the outer shell and the inner shell. The outer end of the spiral fan is connected to the outer shell, and the other end is spirally connected to the inner shell inwardly, and two adjacent spiral fans are surrounded by a fluid channel forming a spiral shape. The micro gas engine includes the above-mentioned heat exchanger. The heat exchanger provided by the present invention adopts a plurality of spiral fans arranged between the outer casing and the inner casing as the main heat exchanging mechanism, and has smaller volume and higher heat exchanging efficiency. The micro gas engine provided by the present invention adopts the above-mentioned heat exchanger, and has smaller volume, lower cost and higher thermal efficiency.
Description
Technical field [0001] The present invention relates to the field of micro-combustion engines, and more particularly to a heat exchanger and a micro-combustion engine. Background technique [0002] Miniature combustion engines are turbine engines in the form of a reflow combustion chamber, and turbine engines generally include three parts: compressors, combustion chambers, and turbines. Typically, a heat exchanger is also disposed outside the combustion chamber of the micro-combustion engine, a heat exchanger for preheating intake and reducing exhaust gas, reducing the emission of nitrogen oxides of micro-combustion engine, while increasing the thermal efficiency of the turbine engine. [0003] The heat exchanger under the prior art is generally stacked by a plurality of intervals or nested heat exchange units, which are complex, large, and low heat transfer efficiency and difficulty in manufacturing and assembly. The heat exchanger is to achieve a large heat exchange power, gene...
