Embodiment 1

[0026] Embodiment 1: It can be clearly seen from Fig. 1 that the heat exchange stainless steel alloy foil coil tube is composed of six stainless steel alloy foil straight tubes 1 with a tube wall thickness of 0.15 mm and five stainless steel alloy foil U-shaped tubes 2 with a tube wall thickness of 0.3 mm. Both pipe ends of the stainless steel alloy foil straight pipe 1 are provided with cup mouths 11 for connecting pipes to be inserted into, and the mouth ends of the cup mouths 11 are provided with bell mouths 12 . The stainless steel alloy foil U-shaped tubes 2 are respectively inserted into the cup openings 11 and bell mouths 12 at both ends of the arranged stainless steel alloy foil straight tubes 1, and the six arranged stainless steel alloy foil straight tubes 1 are connected to form a coiled tube.

[0027] The manufacturing method of the heat exchange stainless steel alloy foil coil of the present invention comprises the following steps:

Embodiment 2

[0040] Embodiment 2: It can be clearly seen from Fig. 2 that this is another structure of stainless steel alloy foil coil for heat exchange. A cup mouth 21 for inserting the straight pipe 1 is provided, and a bell mouth 22 is provided at the mouth end of the cup mouth 21 . The two ends of the arranged stainless steel alloy foil straight pipes 1 are respectively inserted into the cup mouth 21 and bell mouth 22 of the stainless steel alloy foil U-shaped pipe 2, and the six arranged stainless steel alloy foil straight pipes 1 are connected to form a coil pipe.

[0041] The manufacturing method of the heat exchange stainless steel alloy foil coil in this embodiment is the same as that in Embodiment 1.

Abstract

This invention is a heat transferring stainless steel alloy foil coil and its production method. The coil is welded by stainless alloy foil straight pipe and bended pipe. The thickness of the straight pipe wall is 0.02mm-0.3mm, while the thickness of the bended pipe wall is 0.15-0.45mm. The production method includes: material prepare, bended pipe production, bended pipe or straight pipe end making and welding. This invention has reasonable structure and easy technique. The chlorine anion resistant capability of the said coil is higher than 100ppm and increases more than 50% times than that of the copper materials. The strength increases one time. The ductility is nearly the same as that of the copper materials. The heat power is higher than that of the existing heat transferring copper coil. All of its heat superconductivity is suitable for various kinds of condensers and evaporators. This invention can be used on various kinds of air conditioners and refrigerating equipments.

Description

technical field [0001] The invention relates to a heat exchange coil, in particular to a heat exchange stainless steel alloy foil coil which can replace common copper heat exchange tubes and is suitable for air conditioning, refrigeration, and high heat dissipation and a manufacturing method thereof. Background technique [0002] Existing evaporators or condensers used in air-conditioning, refrigeration, refrigerators, and heat dissipation are usually made of copper tubes with good processing performance, heat dissipation performance and certain anti-corrosion ability. As we all know, copper resources are not only scarce, but also expensive. The lack and high cost of copper resources have caused a bottleneck in the supply of materials to the entire industry. Contents of the invention [0003] The object of the present invention is to solve the above existing problems and provide a heat exchange stainless steel alloy foil coil tube which can replace copper material, has be...
