Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] The heat exchanger with anti-blocking function of the present invention includes a shell 1, and a heat exchange coil 2 is arranged in the shell 1. One end of the heat exchange coil 2 is connected to a water inlet pipe 3, and the other end is connected to a water outlet pipe 4. The water inlet pipe 3 and the water outlet pipe 4 all extend out of the housing 1, and the outer walls of the water inlet pipe 3 and the water outlet pipe 4 are uniform. It is in sealing fit with the shell wall of the shell 1. The water inlet pipe 3 is provided with a first valve 5, and the water outlet pipe 4 is provided with a second valve 6. The water inlet pipe 3 on the outside of the first valve 5 passes through the first reversing pipe 7 and the water outlet pipe 4 on the inside of the second valve 6. connected, and there is a third valve 8 on the first reversing pipe 7, ...

The invention relates to a heat exchanger with a blockage prevention function. The heat exchanger with the blockage prevention function comprises a shell, wherein a heat exchange coil pipe is arranged in the shell, one end of the heat exchange coil pipe is connected with a water inlet pipe, the other end of heat exchange coil pipe is connected with a water outlet pipe, the water inlet pipe and the water outlet pipe both extends out of the shell, and the outer walls of the water inlet pipe and the water outlet pipe are both matched with the wall of the shell in a sealed mode. The heat exchanger with the blockage prevention function is characterized in that the water inlet pipe is provided with a first valve, the water outlet pipe is provided with a second valve, the part, on the outer side of the first valve, of the water inlet pipe is connected with the part, on the inner side of the second valve, of the water outlet pipe through a first reversing pipe, the first reversing pipe is provided with a third valve, the part, on the inner side of the first valve, of the water inlet pipe is connected with the part, on the outer side of the second valve, of the water outlet pipe through a second reversing pipe, and the second reversing pipe is provided with a fourth valve. The heat exchanger is high in work efficiency and will not damage a water pump.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to a heat exchanger with an anti-blocking function. Background technique [0002] As a heat transfer device, heat exchanger is widely used in agriculture, chemical industry, construction and other industries. [0003] At present, the heat exchanger used in the industry includes a shell with a water inlet and a water outlet on the side wall of the shell, and a heat exchange coil inside the shell. One end of the heat exchange coil is connected to a water inlet pipe, and the other end is connected to a water outlet pipe. Both the water inlet and outlet pipes protrude outside the shell, and the outer walls of the water inlet and outlet pipes are in a sealed fit with the shell wall of the shell. When in use, use a water pump to pour hot water from the water inlet pipe into the heat exchange coil, and at the same time pour cold water into the shell from the water inlet of the shell, and the hot water ...
