Heat exchangers (also known as heat exchangers or heat exchange equipment) are devices used to transfer heat from hot fluids to cold fluids to meet specified process requirements, and are an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to its operation process, it can be divided into three categories: inter-wall type, mixed type, regenerative type (or regenerative type); According to the compactness of its surface, it can be divided into two categories: compact type and non-compact type.
Household category
Domestic heat exchangers solve the problem of collective heating of homes and hot water in winter. It works on the same principle as a heat exchanger for collective heating. It's just a different size and style.
Can be divided into cast iron type, cylinder type, steel type, water storage type, plate.
The results are good.
Cast iron type
Cast iron type of large volume, heavy weight. However, the copper pipe inside can be opened and checked before buying, it is not easy to be cheated by merchants, and the copper pipe can be replaced after a few years.
Cylinder type
The cylindrical type has small volume and high exchange efficiency. However, the user cannot check the length of the copper tube inside, nor can the copper tube be replaced, and it is not very beautiful.
Steel system
Steel type sizes are large and small. The user can not check the length of the copper pipe inside, and can not replace the copper pipe. But it's more beautiful.
plate-type
Plate type, small size, small weight. High heat exchange efficiency. There is no copper pipe inside. The heat exchange capacity depends on the number of layers. The number of layers can be seen and touched.
scale
All of the above exchangers will produce scale during use. After a few years of use, there will be small water flow and the water is not too hot. But companies specializing in descaling have also sprung up in places like Shijiazhuang. Professional descaling will make it as good as new.
