Header cold water pipe open communication heat absorption heat exchanger and manufacturing process thereof

Abstract

The invention discloses a header cold water pipe open communication heat absorption heat exchanger and a manufacturing process of the header cold water pipe open communication heat absorption heat exchanger. The header cold water pipe open communication heat absorption heat exchanger at least comprises two heat supply pipes, wherein two ends of the heat supply heats are respectively welded with a header, at least one cold water channel is arranged inside a heat supply pipe cavity, ports at two ends of the cold water pipe channel are communicated in open cavity mode, and deposited scales in a cold water pipe can be conveniently cleaned by poured acid liquor. The cold water pipe stores water and absorbs heat, effective heat sources can be fully utilized, the heat is quickly absorbed through multiple dividing walls, the heat is transmitted in step mode, a heat absorption area is enlarged, and due to the fact that water is stored in the headers, the length of flow path of cold liquor is increased, the time of heat exchange is prolonged, heat loss is reduced, and heat exchange efficiency is improved. Longitudinal or transverse flexible installation is achieved by reasonable utilization of space, requirements of users can be met, materials are saved, and production cost is reduced. Product quality is stable and reliable, and service life is prolonged. The same kind of metal material is adopted, the weight is light, transportation is convenient, and logistics transportation cost is saved.

Description

technical field [0001] The invention relates to a heat exchanger for household heat supply, in particular to a heat-absorbing heat exchanger connected with a header cold water pipe with an open opening and its manufacturing process. Water heat exchanger. Background technique [0002] At present, the home heating method has changed from the original wall-mounted type to floor heating, that is, a heating pipe network with a diameter of 20mm and a pipe spacing of 200mm is laid under the floor, and the floor dissipates heat in a large area, and the temperature of the heating water is reduced from above 70 degrees to Only 45 degrees of heating is required, and the indoor temperature can reach a temperature of more than 20 degrees. The existing heat exchanger technology is no longer suitable for the current low water temperature requirements for heating, not only the design is unreasonable but also there are obvious deficiencies: the cold water heat-absorbing pipe in the existing...

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing heat exchangers such as small heat transfer area, low heat exchange efficiency, poor heat absorption effect of the single-channel closed reciprocating coil of the cold water pipe, easy fouling and blockage in the cold water pipe, cannot be poured into acid solution for cleaning, and short service life, etc., the present invention Provided is a heat-absorbing heat exchanger made of the same metal material as the two ends of the header cold water pipe are open and connected, and its manufacturing process. The heat exchanger has a compact structure and a simple manufacturing process. At least one The cold water pipe channel, both ends of the cold water pipe channel are connected by open cavities, which is convenient for pouring acid solution to clean the dirt deposited in the cold water pipe; the cold water pipe stores water and absorbs heat, which can make full use of effective heat sources, and the multiple partitions quickly absorb heat, and the heat is stepped Transfer, increase the heat absorption area, extend the time of heat exchange, reduce heat loss, improve heat exchange efficiency, and reduce production costs
