Combined quick-heating heat exchanger

Abstract

The invention relates to a combined quick-heating heat exchanger, which comprises an inner container and an electric heater. A heating portion of the electric heater is positioned in the inner container, an electricity inlet portion of the electric heater is arranged outside the inner container, and a hot water outlet is arranged on the upper portion of the inner container. The combined quick-heated heat exchanger is characterized by further comprising an outer container and a heat-exchange coiled pipe, the outer container is sleeved outside the inner container and mutually sealed with the inner container, a closed sandwich space is arranged between the outer container and the inner container, a refrigerant inlet communicated with the sandwich space is arranged on one side of the outer container, and a refrigerant outlet communicated with the sandwich space is arranged on the other side of the outer container. The heat-exchange coiled pipe is coiled outside the inner container and positioned in the sandwich space, a water inlet of the heat-exchange coiled pipe is communicated with tap water, and a water outlet of the heat-exchange coiled pipe is communicated with a water inlet at the bottom of the inner container. The combined quick-heating heat exchanger has the advantages that the combined quick-heating heat exchanger is high in heat exchange efficiency, easy in load adjustment, quick in fluid heating start and stable in outputted fluid temperature, and a heating system is more efficient, safer and more comfortable.

Description

technical field [0001] The invention relates to a compound rapid heat exchanger, which belongs to the field of fluid heating. Background technique [0002] Existing fluid heating equipment usually only has one heat source, and cannot be connected to use multiple heat sources at the same time. Existing fluid heating equipment usually has a small inner volume, and when the fluid needs to be heated rapidly, there is a long start-up time, and the temperature fluctuation of the fluid flowing out during the start-up period is large. When the heated fluid needs to be output intermittently, due to the small internal volume, the heat storage cannot be buffered, and it is easy to cause frequent start and stop of the heat source equipment, causing damage to the heat source equipment. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a composite rapid heat exchanger with fast heating start-up speed, stable ...
