Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to the structure of a plate heat exchange unit, in particular to a plate heat exchange unit with an elbow support. Background Art

[0002] The plate heat exchanger unit is a complete set of regional heating control equipment that integrates plate heat exchangers, circulation pumps, water supply pumps, thermometers, pressure gauges, various sensors, pipelines and valves (filters, butterfly valves, check valves, soft connections, etc.) and industrial control. Working principle of plate heat exchanger unit: steam or high-temperature water is sent to the plate heat exchanger unit according to the flow rate required by the heating system under the control of the temperature control valve. The heat exchanger heats the heating (air conditioning) return water of the heat user by indirect heat exchange; the heated water first flows through the filter, and then enters the heat exchanger through the circulation pump to be heated for the user to use, and repeats. The primary heat medium returns to the primary heating network after heat exchange in the plate heat exchanger unit. The water loss of the system is automatically supplemented by the water supply pump according to the set pressure to ensure the stable pressure and normal operation of the system. Plate heat exchanger units are widely used: used in HVAC, refrigeration, energy and electricity, metallurgy, medicine, chemical industry, food, electronics, shipbuilding and environmental treatment, seawater desalination and other fields. It is used for heating, air conditioning, bathing water, domestic water, winter water for swimming pools in civil buildings such as factories, offices, schools, residential quarters, villas, and commercial buildings such as shopping malls, hotels, restaurants, and resorts.
