A metal heat exchanger for carrying out heat exchange with surrounding air. The present invention relates to a metal heat exchanger made of metal radiating fins made of non lead alloy material on the surface of a lead alloy tube nested or connected with the surrounding air for heat exchange. Lead alloy heat exchanger than the existing Aluminum Alloy, copper, iron or steel and other metal heat exchanger in air and heat energy, but the density and quality of lead alloy, there are heavy and hot issues for technology area is not big enough. The invention solves the technical scheme of lead alloy heat exchanger for their heavy and technical problems in the area of heat is not big enough is: in the metal heat radiating tube outer surface of nested lead alloy tubes or welding properties of lead alloy to produce with the surrounding air heat exchanger. Its main purpose is: with the nature of non lead alloy metal sink lead alloy heat exchanger, the heat transfer process in its surrounding air, which can significantly reduce their weight and energy saving, the heat exchanger and increase the heat transfer area.
【技术实现步骤摘要】
一种用于与周围空气进行热交换的金属热交换器所属
-本专利技术涉及一种用于与周围空气进行热交换的金属热交换器,尤 其是在与周围空气进行热交换的过程中能够显著增大换热面积,从而 达到提高换热效果的金属热交换器。
技术介绍
目前,公知的用于与周围空气进行热交换的金属热交换器,如空 气调节器、冰箱、冷气机及用于室内供暖的蒸发器、冷凝器、散热器 等热交换器,普遍采用铜质、铝合金、钢质或铁质等金属材料进行制 造热交换器,或者在铜管的身上嵌套铝合金散热片。尚没有出现在铅 合金管的身上嵌套或连接非铅合金的金属散热片。
技术实现思路
为了克服采用铜质、铝合金、钢或铁质等金属热交换器在与周围 空气进行热交换时存在的热量消耗大的现象,已有人提供一种铅合金 的金属热交换器。由于铅合金的密度、质量大,为了减轻铅合金热交 换器自身重量并且增大铅合金管的散热面积,现在提供一种在铅合金 管的管体外表上嵌套或连接非铅合金的金属散热片的新的技术方案。本专利技术解决其技术问题所采用的技术方案是采用铅合金材料所 制成的铅合金管作为本专利技术的热交换器的主体。当该铅合金热交换器在与其周围空气进行热交换时,不论是放热或是吸热,在达到同量温度要求时,因铅的比热容小,所以在与空气换热时消耗的热量可明显减少。了为减轻铅合金热交换器自身重量并且增大铅合金管的散热面积,本专利技术在这种换热器的铅合金管体外部嵌套或者连接非铅合金性质的金属散热片。本专利技术的有益效果是,既能确保铅合金热交换器在与其周围的空气进行热交换时显著节能,又可以大大减轻其自身重量并且增大其换热面积,从而显著提高其换热效果。具体实施例方式在 ...
