Water collection box heat exchanger

Abstract

The invention provides a water-collecting-box type heat exchanger, and belongs to the technical field of heat exchanging. The water-collecting-box type heat exchanger solves the problem that an existing heat exchanger is not reasonable in design and inconvenient to install. The water-collecting-box type heat exchanger comprises a water inlet pipe, a water outlet pipe, a cylindrical shell, a first straight pipe and a heat exchange body, wherein a smoke channel is formed inside the cylindrical shell, the first straight pipe is transversely arranged inside the smoke channel in a penetrated mode, the heat exchange body is arranged on the first straight pipe in a sleeved mode, a plurality of second straight pipes are transversely arranged on the heat exchange body in a penetrated mode, a first inner lateral plate and a second inner lateral plate are attached to the two opposite sides of the shell respectively and both provided with first through holes and second through holes, the outer side of the shell is provided with a plurality of third straight pipes, the first inner lateral plate and the second inner lateral plate are both provided with a plurality of third through holes, the outer side of the first inner lateral plate is provided with a first outer lateral plate, and the first outer lateral plate is provided with a first connecting body, a second connecting body and a third connecting body; the outer side of the second inner lateral plate is provided with a second outer lateral plate, and the second outer lateral plate is provided with a fourth connecting body, a fifth connecting body, a sixth connecting body, a seventh connecting body and an eighth connecting body. The water-collecting-box type heat exchanger has the advantages of being convenient to install, saving materials and the like.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and relates to a heat exchanger, in particular to a water collection box type heat exchanger. Background technique [0002] When the existing heat exchanger is working, cold water enters through the water inlet pipe, and then flows through the coil coiled on the water tank shell. To the water outlet of the heat exchanger, use a U-shaped pipe at the water outlet of the heat exchanger to turn the water back to the heat exchange section, pass through the second straight pipe, and flow back to the water inlet of the heat exchanger, and then use the U-shaped pipe to flow the water through the The straight pipe is folded back to the heat exchange section, and this is repeated several times, and the water after heat exchange flows out through the outlet pipe. In the existing heat exchanger, two heat exchange straight pipes are connected by U-shaped pipes. The more the number of heat exchange stra...

AI Technical Summary

Problems solved by technology

In the existing heat exchanger, two heat exchange straight pipes are connected by U-shaped pipes. The more the number of heat exchange straight pipes, the more U-shaped pipes are needed, which leads to the complex structure of the whole heat exchanger. The U-shaped pipes need to be connected separately, which is time-consuming and laborious. The connection is inconvenient and the connection effect is poor. If there is leakage after the connection is completed, it is inconvenient to maintain and will increase the manufacturing cost.

Moreover, the existing heat exchanger is made of copper material. With the prolongation of service time, the material itself will be corroded by a small amount of nitrogen oxide aqueous solution condensed in the flue gas during normal use, thereby greatly reducing the main heat exchange rate. Due to the performance of the heat exchanger, quality problems such as reduced thermal efficiency, excessive flue gas emissions, perforated water leakage of the heat exchanger, etc., not only greatly reduce the service life of the heat exchanger, but also seriously affect the safety of the product.
