Description

technical field

[0001] The invention belongs to the technical field of heat exchanger manufacturing, and relates to a general working condition applicable to petroleum, chemical industry, metallurgy, and electric power, especially applicable to the occasion of dual heat source compound heat pump technology in air source heat pump, realizing three kinds of media in the same heat pump A new type of three-medium compound heat exchanger for synchronous heat exchange in the exchanger. Background technique

[0002] Building energy consumption is a major item of energy consumption. It is an important way to save energy by converting low-grade heat energy that cannot be directly used into heat pump technology air conditioners that can use high-level energy. Most of the heat exchangers currently used in the field of refrigeration and air conditioning can only realize heat exchange between two media. The patent application "Fin-Tube Type Three-Medium Composite Heat Exchanger" (applic...

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 and figure 2 As shown, the three-medium composite heat exchanger of the present invention comprises an upper head 1 and a lower head 7, and a rectangular frame is arranged between the upper head 1 and the lower head 7, and the frame is composed of an upper partition 12, a lower partition Plate 11 and two side plates 4 are formed. In the frame, between the two side plates 4, multiple groups of heat exchange plate bundles are arranged in parallel. The plates 11 are fixed; a plurality of fins 8 are arranged horizontally between two adjacent groups of heat exchange plate bundles, and a plurality of fins are also arranged horizontally between the heat exchange plate bundles adjacent to the side plate 4 and the side plate 4 8. There is a gap between two adjacent fins 8; each group of heat exchange plate bundles is compos...
