Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2-3, the present invention provides a novel integrated coaxial double-pipe heat exchanger, which comprises an inner pipe and an outer pipe 1 sleeved outside the inner pipe 4, wherein an interlayer for fluid circulation is formed between the outer pipe and the inner pipe, and the outer pipe is provided with an exhaust device 2 and a pressure relief device 3; the exhaust device is positioned at the top end of the novel integrated coaxial double-pipe heat exchanger. In the present application, the exhaust device may generally use an exhaust valve, the pressure relief device may generally use a pressure relief valve, and the installation of the exhaust valve and the pressure relief valve is well known to those skilled in the art.

The utility model provides a novel integrated coaxial double-pipe heat exchanger, through having installed exhaust apparatus 2 and pressure relief device 3 at the outer tube, exhaust apparatus 2 install in the heat exchanger topmost in order to do benefit to with the utility model discloses the gas of the system product that the product matches is got rid of to reduce the influence of gas accumulation in the system product to the system product, pressure relief device 3 installs on the heat exchanger pipeline, in order to do benefit to with the utility model discloses the pressure release of the system product that the product matches is with in order to protect this system product. In use, the interlayer is a passage through which liquid fluorine passes, and the inner tube is a passage through which water passes.
