Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and in particular to a heat exchanger which is easy to clean. Background Art

[0002] A heat exchanger, also known as a heat exchanger or heat exchange equipment, is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. The current heat exchanger mainly includes a first water inlet pipe, a heat exchange tube and a motor, and secondly includes a first water outlet pipe, a second water inlet pipe and a stirring blade. The specific process is that the first fluid enters the heat exchange tube through the first water inlet pipe, and the filter plate installed in the first water inlet pipe filters impurities in the fluid. The first fluid in the heat exchange tube is discharged through the first water outlet pipe, and the second fluid enters the cylinder through the second water inlet pipe, so that the heat of the first fluid in the heat exchange tube is transferred to the second fluid through the tube wall to heat the second fluid. The motor is running, and the stirring blade stirs the second fluid with the operation of the motor to accelerate the movement of molecules.

[0003] For example, a heat exchanger disclosed in publication number CN215909722U relates to the technical field of heat exchangers. The utility model includes a barrel box, wherein a bracket leg is fixedly connected to the bottom of the barrel box, a support seat is fixedly connected to the lower end of the bracket leg, a first water inlet pipe is fixedly connected to the upper end of the barrel box side surface, a first water outlet pipe is fixedly connected to the lower end of the barrel box side surface, a second water inlet pipe is fixedly connected to the upper end of the barrel box side surface, a spiral heat exchange pipe is fixedly connected to one end of the second water inlet pipe, a second water outlet pipe is fixedly connected to the other end of the spiral heat exchange pipe, a dome cover is fixedly connected to the upper end of the barrel box, and a stirring device is fixedly connected to the inside of the dome cover. The utility model removes impurities in the first fluid by filtering the first fluid through the filter net when the first fluid enters the second water inlet pipe, thereby improving the purity of the first fluid.

[0004] However, an existing heat exchanger cannot conveniently clean the filter plate. When the heat exchanger needs to be used, the first fluid enters the heat exchange tube through the first water inlet pipe, and the filter plate installed in the first water inlet pipe filters impurities in the fluid. The first fluid in the heat exchange tube is discharged through the first water outlet pipe, and the second fluid enters the cylinder through the second water inlet pipe, so that the heat of the first fluid in the heat exchange tube is transferred to the second fluid through the tube wall to heat the second fluid. Since the through holes on the filter plate will be blocked during long-term filtration, it is difficult for the first fluid to quickly pass through the filtration of the filter plate and enter the heat exchange tube, thereby reducing the working efficiency of the heat exchanger. Utility Model Content
