Description

Technical Field

[0001] The utility model relates to the field of heat exchange units, in particular to a hybrid energy-saving heat exchange unit. Background Art

[0002] The heat exchanger unit is composed of a heat exchanger, a temperature control valve group, a steam trap group (when the heat medium is steam), a circulating pump, an electric control cabinet, a base, pipelines, valves, instruments, etc., and can be equipped with an expansion tank, water treatment equipment, a water pump frequency conversion control, a temperature control valve, remote communication control, etc., to form a complete heat exchange station. The heat exchanger unit has a standardized and modular design, complete configuration, easy installation, and high efficiency and energy saving. The heat exchanger unit has the advantages of compact structure, reliable operation, simple and intuitive operation, and is the preferred high-efficiency and energy-saving product. This product is suitable for sanitary hot water in residences, offices, factories, mines, hospitals, hotels, schools and other occasions. The integral heat exchanger unit can be used for both water-water exchange and steam-water exchange. The hybrid heat exchanger unit belongs to a type of heat exchanger unit. When the hybrid energy-saving heat exchanger units on the market are in use, the impact force generated during the rapid circulation of liquid will be transmitted to the flange connection end. At the same time, the flange connection end is extremely prone to loosening after being subjected to multiple impact forces. In addition, when performing heat exchange operations, the accumulation of scale in the heat exchange pipeline is too thick, which will directly affect the work efficiency during the heat exchange operation.

[0003] For example, in a patent for a hybrid energy-saving heat exchanger unit (announcement number: CN217716060U), it includes a positioning base, a plate heat exchanger body is fixed with screws at a position on one side of the top of the positioning base, and the liquid inlet end of the plate heat exchanger body is flange-sealed and connected with a liquid inlet pipe, and a threaded collar is spirally installed on the outside of one side of the liquid inlet pipe. Through the arranged liquid inlet pipe, spring, movable clamping ring, combined cover, plate heat exchanger body and threaded collar, after the movable clamping ring realizes lateral stretching from right to left and pre-closes the end faces with multiple bolts fixing a group of flange plates, when the liquid circulates rapidly, the movable clamping ring will use the rebound force generated by the deformation of the spring to buffer the impact force on the flange connection end during the rapid circulation of the liquid, and effectively avoid the flange connection end from being loosened due to the impact generated during the long-term circulation of the liquid.

[0004] The above patent uses a movable clamp and a spring to effectively prevent the flange connection end from loosening due to the impact caused by the long-term circulation of liquid. In daily use, the data of liquid circulation and heat exchange in the device cannot be monitored, making it difficult for the staff to understand the use of the device, thereby reducing the staff's sense of use and reducing the scope of application of the device. Therefore, it is necessary to propose a hybrid energy-saving heat exchanger unit to solve the above problem. Utility Model Content
