Embodiment Construction

[0009] like figure 1 As shown, the heat exchanger with a compensation coil includes a shell 1, and a partition plate 7 and a cold water pipe 2 are arranged inside the shell 1. The shell 1 is provided with a hot water inlet pipe 6, a hot water outlet pipe 3, and a cold water inlet pipe. The pipe 4 and the cold water outlet pipe 5, the cold water inlet pipe 4 and the cold water outlet pipe 5 are separated in the middle, the cold water inlet pipe 4 is connected to the cold water pipe 2, and the cold water pipe 2 is a segmented water pipe, and the two segmented water pipes communicate with each other through a closed space One end of the cold water pipe 2 is fixed on the shell 1, and the other end is freely supported by the shell 1; the heat exchanger shell 1 has a compensation ring 8.

[0010] The shape of the compensation ring 8 is arched, distributed on the upper and lower sides of the housing 1 , and the arched space of the compensation ring 8 communicates with the inner space...

Abstract

The invention provides a heat exchanger with a compensating ring. The heat exchanger with the compensating ring comprises a shell; the shell is internally provided with a baffle plate and cold water tube; the shell is provided with a hot water inlet tube, a hot water outlet tube, a cold water inlet tube and a cold water outlet tube; the cold water inlet tube and the cold water outlet tube are separated from the middle; the cold water inlet tube is communicated with the cold water tube which is a sectional-type water tube; two sectional-type water tubes are communicated through an enclosed space; one end of the cold water tube is fixed on the shell, and the other end of the cold water tube is supported freely by the shell; and the shell of the heat exchanger is provided with a compensating ring. The heat exchanger with the compensating ring related to the invention is simple in structure; and in order to overcome the mutual force of the shell and the cold water tube caused by different thermal expansion degrees, the compensating ring is designed to release the mutual acting force.

Description

technical field [0001] The invention relates to a heat exchanger with a compensation coil. technical background [0002] The heat exchange tube is one of the components of the heat exchanger, which is placed inside the cylinder and used for heat exchange between two media. In addition to bare tubes, heat exchangers can also use a variety of enhanced heat transfer tubes, such as finned tubes, threaded tubes, spiral grooved tubes, etc. When the heat transfer coefficient on both sides of the inner diameter of the tube differs greatly, the fins of the finned tube should be arranged on the side with the lower heat transfer coefficient. Commonly used materials are carbon steel, low alloy steel, stainless steel, copper, copper-nickel alloy, aluminum alloy, titanium, etc. In addition, there are some non-metallic materials, such as graphite, ceramics, polytetrafluoroethylene and so on. In the existing heat exchanger, both ends of the heat exchange pipeline are generally fixed on t...
