Embodiment 1

[0069] The present embodiment takes the header as an example to further illustrate the present invention:

[0070] The round tube header double-wall heat transfer pinch welding heat exchanger and its manufacturing process of the present invention include: two headers, two or more tap water connected to the outer pipe between the two headers; the characteristics are: : The tap water is connected to the outer pipe with a heating pipe, and the tap water heat-absorbing inner pipe is inserted into the heating pipe to form a double-row channel for heat transfer with double partitions. The heating pipe is connected. For heating outlet. The heating inlet and heating outlet are connected to the upper and lower parts of the side wall at one end of the header, and the tap water inlet and tap water outlet are connected to the upper and lower parts of the head blocking plate (end cover) of the same header.

[0071] The manufacturing process of the present invention (taking the circular tu...

Embodiment 2

[0081] In this embodiment, the present invention is described by taking the header as a D-shaped header as an example.

[0082] 1. The center hole of the orifice plate of the D-shaped header is punched inward according to the diameter of the outer pipe connected to the tap water, and the edge height of the hole is 2-2.5 mm, and the edge height of the two sides of the orifice plate is 2-3 mm, and the C-shaped plate is pressed and strengthened. There are 4 ribs, and the outer pipe connected to the tap water is inserted into the drawing hole of the orifice plate of the D-shaped header without gaps. The heating pipe, the straight pipe connected to the heat supply, and the tap water heat-absorbing inner pipe are connected, and the whole is movable, and can expand freely when heat expands and contracts, reducing the water leakage rate of the heating system. After the heating and heating pipe system is connected, it is qualified if there is no water leakage after the pressure test. T...

Abstract

Disclosed are a heat transfer side kneading welding heat exchanger with headers and double dividing walls and manufacturing process of the heat transfer side kneading welding heat exchanger. The heat transfer side kneading welding heat exchanger comprises two headers, and the headers are round tube headers or D-shaped headers. A warm air inlet, a warm air outlet, a tap water inlet and a tap water outlet are fixedly connected onto each header, two or more tap water through outer tubes are fixedly connected between the two headers and are communicated with each other via the headers, warm air heat supply tubes penetrate into the tap water through outer tubes and are through, one end of each warm air heat supply tube is connected to the corresponding warm air inlet while the other end of the warm air heat supply tube is connected with the corresponding warm air outlet, and tap water heat absorbing inner tubes are disposed in parts or all of the warm air heat supply tubes and communicated with the headers. Cold water tube channels are added in cavities of the heat supply tubes to form the double dividing walls to realize convection heat transfer, a cold fluid double-pass channel is formed to realize pure backflow, average temperature difference is increased, and heat efficiency is improved.
