Problems solved by technology

[0005] The present invention proposes a radiator coil for a closed cooling tower and a manufacturing method thereof. The purpose of the invention is to solve the problems that the existing cooling tower radiator coil is not easy to produce, consumes a lot of resources, and is easy to freeze and crack. It is manufactured in a molded manner, and the coil produced has no joints and no welding points, thus providing a coil for radiators that is easy to produce, saves costs, and has high heat dissipation efficiency

Embodiment Construction

[0019] As attached Figure 1-2 As shown, the coil for a closed cooling tower radiator is characterized by an integrally formed continuous curved pipe structure. The cross-section of the flattened coil is in an olive shape, with a width of 13mm and a height of 35mm. The coil tube uses T2 copper tube, 304, 316 stainless steel or alloy tube and other materials, the diameter of the coil tube is 19mm, and the wall thickness is 0.6mm.

[0020] The manufacturing method of coils for closed cooling tower radiators includes the following steps:

[0021] (1) It is flattened into an olive shape by mechanical clamping, which is relatively straight. The feeding length is determined according to the product specifications, and finally into an olive shape with a width of 13mm and a height of 28mm;

[0022] (2) Continuously bend into one piece from a length of 90 meters by a pipe bender to achieve no joints and no solder joints; figure 2 Shown

[0023] (3) After the coils are bent into pieces, they ...

Abstract

The invention relates to a coil for a closed cooling tower heat radiator, which is characterized by being of a continuously-bent pipeline structure which is integrally molded, the cross section of a flattened coil is shaped like an olive with the width of 13mm and the height of 35mm. A manufacturing method of the coil comprises the following steps of (1) flattening the coil to be shaped like an olive with the width of 13mm and the height of 35mm by using a machine; (2) continuously bending the coil into a piece from the length of 90m by using a pipe bending machine to achieve the aims of having no joints and welding spots; and (3) forming a coil group, and then, assembling the coil group into a cooling tower. The coil has the advantages that 1, the problems of short life, low heat exchange efficiency, material waste and the like existing in traditional elbow pipes are solved; 2, due to the adoption of the olive-shaped coil, the condensation area is increased, the transportation width is reduced, spray water can be uniformly sprayed, and saturation exchange reaches the optimal cooling effect (100%); and 3, the coil is convenient to manufacture and low in market price and can be largely purchased for standby application.

Description

Technical field [0001] The invention relates to a coil for a closed cooling tower radiator and a manufacturing method, and belongs to the technical field of radiators. Background technique [0002] The coil tubes used in the traditional closed cooling tower radiator need to be ordered and produced according to the specified size, and the delivery cycle is long; and in the production, the method of welding the straight tube and the elbow will waste a lot of copper welding rod and Oxygen acetylene. [0003] At the same time, the coil becomes soft after high-temperature welding, resulting in a large number of welded joints. During pressure test, leaks often occur, which requires repeated repairs and pressure test to 10-15kg, resulting in complicated procedures. [0004] In addition, after the product was delivered to the user, there were a few user management errors in winter, which caused a series of problems such as the urgent need to purchase a new one after the product was frozen a...
