Problems solved by technology

[0002] At present, the structure of the heat source part of the heat exchanger commonly used for heat exchange generally adopts a circular straight tube or a spiral tube. The contact area between the heat source tube wall and the heated fluid is small, and the heat load is low; the heat source tube wall is thicker, and the inner wall and the heated fluid Large temperature difference on the outer wall, low heat transfer rate, large heat loss, low heat exchange rate, and large demand for heat sources, resulting in bulky heat exchangers, high manufacturing costs, and limited application range

Embodiment Construction

[0011] The new core tube heat exchanger shown in Figure 1 includes a casing 1, an end cover 2, a heat source end tube 3 and a heat exchange tube 4 are respectively arranged on the end cover 2, and a closed body composed of the casing 1 and the end cover 2 is arranged. The heat source core tube 5 is composed of flat tubes 6 arranged in parallel at a certain interval, the heat source core tube 5 communicates with the heat source end tube 3, and the heat exchange tube 4 communicates with the gap between the heat source core tube 5, forming the flat tube of the heat source core tube 5 6 is welded by more than one U-shaped hollow flat tube and the longitudinal section of the end is semicircular. The heat source core tube 5 is connected to the summary tube 8 at the end 7 of the flat tube 6 forming the heat source core tube 5 and the heat source end tube 3 connected.

Abstract

The heat exchanger as one accessory for boiler or steam condensating equipment includes casing, end caps with heat source end pipe and heat exchanger pipes, and flat heat source core pipes arranged in certain intervals inside the enclosure comprising the casing and the end caps. The heat source core pipes are connected to the heat exchange pipes and they are produced with metal section and through welding and punching. The heat exchanger has high heat load, high heat exchange rate, small volume, low cost and wide application range.

Description

technical field [0001] The invention relates to a heat exchange device and a manufacturing process thereof. Background technique [0002] At present, the structure of the heat source part of the heat exchanger commonly used for heat exchange generally adopts a circular straight tube or a spiral tube. The contact area between the heat source tube wall and the heated fluid is small, and the heat load is low; the heat source tube wall is thicker, and the inner wall and the heated fluid The temperature difference of the outer wall is large, the heat transfer rate is low, the heat loss is large, the heat exchange rate is not high, and the demand for the heat source is large, resulting in a bulky heat exchanger, high manufacturing cost, and limited application range. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a new core tube heat exchang...
