Embodiment 1

[0069] In this embodiment, the header is a round tube header as an example to further illustrate the present invention:

[0070] The double-wall heat transfer kneading edge welding heat exchanger of the round tube header of the present invention and its manufacturing process include: two headers, two or more tap water communicating outer pipes are connected between the two headers; and the feature is :Tap water is connected to the outer pipe with a heating heating pipe, and the inner pipe is inserted into the heating heating pipe to form a double-row channel and double-walled heat transfer. The heating pipe is connected, and the beginning of the connecting is the heating inlet and the other end It is the heating outlet. The heating inlet and the heating outlet are connected to the upper and lower parts of the side wall of one end of the header, and the tap water inlet and the tap water outlet are connected to the upper and lower parts of the same header block (end cover).

Embodiment 2

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

[0082] 1. The center hole of the orifice plate of the D-shaped header is punched according to the diameter of the outer pipe connected to the tap water. The height of the hole is 2~2.5mm, and the height of the two sides of the orifice is 2~3mm. The C-shaped plate is strengthened by pressing There are 4 ribs, the tap water connecting outer pipe is inserted into the drawing hole of the D-shaped header orifice plate without gaps, and the drawing hole edge of the orifice plate is consistent with the tap water connecting outer pipe port edge, and the kneading edge self-fusion flat welding method is connected by circumferential seam welding. The heating pipe is connected to the straight pipe for heat supply. After the inner pipe of the tap water heat absorption is connected, the whole is movable. The heat expansion and contraction can expand freely, reducing the water leakage ...

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.
