Abstract
The invention discloses a heat exchanger made by full stainless steel. The heat exchanger comprises a stainless steel shell, a stainless steel main heat exchanger arranged at the top of the stainless steel shell and stainless steel coil pipes connected with the stainless steel main heat exchanger and is characterized in that the heat exchanger comprises a straight pipe and flow channels; the straight pipe is embedded into the stainless steel shell; and the flow channels are integrally formed onto the stainless steel shell for series connection of the straight pipe. Compared with a conventional heat exchanger, the heat exchanger made by full stainless steel has following beneficial effects: fine corrosion resistance is obtained; due to the fact that the coil pipes are composed of the straight pipe embedded into the stainless steel shell and the flow channels formed in the stainless steel shell, welding joints between the coil pipes and the stainless steel shell are reduced, thereby efficiently decreasing water-leakage probability arising from poor welding. In the meantime, a heat exchange area is enlarged. Smoke and water-flow resistance are small. High heat exchange efficiency is obtained.

Detailed description of the invention
Understand essence of the present invention better for convenience of those skilled in the art, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As Figure 1-Figure 4, a kind of all steel heat exchanger, comprising: Stainless Steel Shell 1, is arranged on the primary stainless steel heat exchanger 2 at Stainless Steel Shell 1 top, and the Stainless Steel Coil 3 be connected with primary stainless steel heat exchanger 2; It is characterized in that, comprise straight tube and runner 4, described straight tube is embedded in Stainless Steel Shell, and described runner 4 is one-body molded connects straight tube in Stainless Steel Shell.
In the present embodiment, preferred Stainless Steel Shell 1 comprises the header board 1-1 fitted together, rear plate, left installing plate 1-2 and right installing plate 1-3.Described straight tube comprises the front coil pipe 3-1 be embedded in header board 1-1 and the rear coil pipe be embedded in rear plate.Described runner 4 comprises the left runner 4-1 be positioned on left installing plate 1-2 and the right runner 4-2 be positioned on right installing plate 1-3.Described front coil pipe 3-1 is communicated with right runner 4-2 respectively by left runner 4-1 with the two ends of rear coil pipe.
