An expansion heat exchanger

Abstract

The invention provides an expansion type heat exchanger based on mixed heat exchange. The expansion type heat exchanger comprises an expansion section, a water supply section, a partition, a water supplement port, an inlet, an outlet, a direct mixing heat exchanger, a water distribution mechanism, a filler, an annular weir plate, an automatic exhaust valve and a liquid level sensor. The heat exchanger and an expansion water tank are organically combined, the structure is reasonable and compact, the utilization rate of equipment is increased, the manufacturing cost is lowered, and the occupiedspace is reduced. By the adoption of the expansion type heat exchanger, the mixed cold and hot compensation heat exchange of cold and hot water is realized, the environmental heat exchange load is reduced, and meanwhile water supplement, constant pressure and elimination of system gas or over-filled water are realized. The expansion type heat exchanger is flexible and convenient to use, compact instructure and environmentally-friendly, saves water, saves energy and is widely applicable to cold and hot water supply occasions with different temperature regions and different heat loads.

Description

technical field [0001] The invention relates to an expansion heat exchanger, in particular to an expansion heat exchanger based on mixing heat exchange. Background technique [0002] At present, the shortage of laboratory space and the aging of equipment are common phenomena in colleges and universities. Even if the laboratory is recycled and the public arrangement is very crowded, the relevant water and sewage facilities are unsustainable, which has become a luxury. [0003] When water operation is involved, the upper and lower water configuration is required. At present, tap water is often used as a cooling medium, and tap water is directly discharged into the sewer through pipelines after use. If heat source water is required, a separate heating device is often required. This method of operation has at least the following disadvantages: it needs to configure the upper and lower water, which increases the cost and safety hazards; it needs to be operated near the place wh...

AI Technical Summary

Problems solved by technology

This method of operation has at least the following disadvantages: it needs to configure the upper and lower water, which increases the cost and safety hazards; it needs to be operated near the place where there is an upper and lower water channel, which is inconvenient to operate; the tap water used as the cooling medium is used for one-time use, resulting in a huge waste of water resources. Waste; the direct discharge of cold and heat sources causes great energy waste and environmental heat pollution

If the heat exchanger and the expansion tank are set up separately and the functions are scattered, the utilization rate of the equipment cannot be improved, the manufacturing cost is high, and the space occupied is large

[0004] The current surface water-water heat exchange equipment has low heat exchange efficiency and high energy consumption
