Bag and tube type vacuum attachment tube bundle and manufacturing method thereof

Abstract

The invention discloses a bag and tube type vacuum attachment tube bundle and a manufacturing method of the bag and tube type vacuum attachment tube bundle. The bag and tube type vacuum attachment tube bundle is characterized by comprising a heat exchange bag and an S-shaped heat exchange coiled tube, wherein the S-shaped heat exchange coiled tube is located on the same plane. The heat exchange coiled tube is arranged in the heat exchange bag, and a liquid inlet tube and a liquid outlet tube of the heat exchange coiled tube are exposed out of the heat exchange bag. The heat exchange bag comprises an air exhaust faucet. After the air in the heat exchange bag is extracted through the air exhaust faucet to form the vacuum, the front bag face and the rear bag face of the heat exchange bag areattached, and the front bag face and the rear bag face of the heat exchange bag and the outer side wall face of the heat exchange coiled tube are in close attachment. The bag and tube type vacuum attachment tube bundle has the beneficial effects that the heat exchange bag with high decay resistance covers the surface of the heat exchange coiled tube in a vacuum negative-pressure attachment mode when a tube material with high heat conductivity is adopted by the heat exchange coiled tube, and therefore the heat exchange coiled tube on a heat exchanger can keep high heat conductivity, and the decay resistance of the heat exchange surface is also enhanced. By the adoption of the vacuum negative-pressure attachment, the heat exchange coiled tube and the heat exchange bag can be completely attached with each other, no gaps exist between the heat exchange coiled tube and the heat exchange bag, a material which can conduct heat is adopted by the heat exchange bag, the heat dissipation area ofthe heat exchanger is increased, and therefore the service life of the heat exchanger can be prolonged, and the heat exchange efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of heat exchange equipment, in particular to a bag-tube vacuum-bonded tube row and a manufacturing method thereof. 【Background technique】 [0002] The main heat exchange components of some heat exchangers at this stage generally adopt the structure of heat exchange tubes for heat exchange. Because the heat exchanger is placed outdoors, it will be affected by the environment and reduce the service life of the equipment. In order to enhance the service life of the traditional heat exchange tube, it often uses high-corrosion-resistant tubes for heat exchange, and high-corrosion-resistant tubes generally Poor heat transfer performance, such as high-corrosion-resistant titanium alloy pipes, stainless steel pipes, galvanized pipes, etc., which results in low heat transfer efficiency of the heat exchanger, and if only high heat transfer performance pipes are used to improve The heat exchange efficiency of heat e...

Because the heat exchanger is placed outdoors, it will be affected by the environment and reduce the service life of the equipment. In order to enhance the service life of the traditional heat exchange tube, it often uses high-corrosion-resistant tubes for heat exchange, and high-corrosion-resistant tubes generally Poor heat transfer performance, such as high-corrosion-resistant titanium alloy pipes, stainless steel pipes, galvanized pipes, etc., which results in low heat transfer efficiency of the heat exchanger, and if only high heat transfer performance pipes are used to improve The heat transfer efficiency of heat exchangers, such as copper tubes, aluminum tubes, etc., is relatively short due to their poor corrosion resistance
