Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] Such as figure 1 As shown, an aluminum ice storage coil includes aluminum heat exchange tubes 3 , diverting headers 1 , converging headers 2 , and spacers 4 .

[0022] The heat exchange tubes 3 and headers are made of pure aluminum or aluminum alloy, and the headers are divided into diverting headers 1 and confluence headers 2 . The two headers are equidistantly crossed with small holes, half of the holes are located under the header, and half of the holes are located on the side of the header; each small hole is connected to one heat exchange tube 3, and the side of the diversion header 1 is connected to the hole The heat exchange tubes run from top to bottom in a serpentine manner, and finally flow into the confluence header 2 through the opening at the lower part of the confluence header. The heat exchange tubes connected to the openings at the lower part of...

Abstract

The invention discloses an aluminum ice storage coiler. Heat exchange tubes and headers of the ice storage coiler are made of pure aluminum or aluminum alloy. The heat exchange tubes are S-shaped and formed by bending of a whole extrusion formed aluminum tube by 180 degrees. The whole coiler is free of welding seams except the heat exchange tubes and header connection positions, which are welded. The outer diameter of the aluminum tube is in a range of 15mm to 35mm, and the wall thickness of the aluminum tube is in a range of 1.5mm to 3mm. The outer diameters of the headers are in a range of 100mm to 250mm. The heat exchange tubes are arranged into a quincunx or a # shape. Each of the heat exchange tubes is equidistant from the peripheral heat exchange tubes, and space is between 40mm and 200mm. The coiler is outstanding in ice storage and ice melting performances, high in corrosion resistance and low in weight.

Description

technical field [0001] The invention belongs to the field of energy storage equipment, in particular to an aluminum ice storage coil. Background technique [0002] As the core equipment of the ice storage system, the ice storage coil can store the cooling capacity produced by the main unit of the ice maker in the form of ice at night, and melt the ice when the air conditioner needs to cool during the day, so as to obtain the required cooling capacity. Therefore, the performance of the ice storage coil largely determines the energy efficiency ratio of the ice storage air conditioning system and whether the system can operate reliably. The main factors affecting the performance of the ice storage coil are the structure and layout of the heat exchange tubes inside the ice storage coil, the thermal conductivity and corrosion rate of the materials used for the heat exchange tubes, etc. [0003] At present, the heat exchange tubes of ice storage coils on the market are made of hi...
