High-efficiency module back-stroke displacement heat exchanger

Abstract

The invention relates to a heater exchanger, in particular to a high-efficiency module back-stroke displacement heat exchanger which is characterized by also comprising a cylinder. One side of the cylinder is provided with an open hole which enables chamber cylinders to horizontally extend into the cavity of the cylinder. Back stroke partition plates are vertically and horizontally arranged at intervals above the chamber cylinder in the cavity of the cylinder to form a plurality of back stroke mixing chambers, and horizontal chamber cylinders and vertical cylinders are communicated with each other through porous radiant tubes. When in working, primary fluid enters an end socket from a primary fluid inlet flange, flows through a horizontal heat exchange tube extending into the end socket, and flows out from the outlet of the heat exchange tube extending into the end socket and the primary fluid outlet flange through back strokes partitioned by a U-shaped heat exchange tube and an end socket partition plate. Secondary fluid flows through a secondary fluid inlet flange at the lower end of the chamber cylinder at the outer side of the cylinder, and is sufficiently mixed and stirred through a back stroke mixing chamber, back stroke is carried out, and the secondary fluid subjected to the treatment is discharged from a secondary fluid outlet flange on the upper end of the cylinder. The invention provides the high-efficiency module back-stroke displacement heat exchanger which can improve the thermal efficiency, the energy utilization rate and the water yield, reduce the cost andreduce the architectural space, is convenient to maintain and clean, and has simple manufacturing process.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a high-efficiency module return volume heat exchanger. Background technique [0002] In the prior art, volumetric heat exchangers mainly include: RV series volumetric heat exchangers, which are divided into two types: vertical and horizontal. The existing vertical and horizontal volumetric heat exchangers combine heat exchange tubes with The tube plate is connected, and then inserted into the shell of the volumetric heat exchanger by welding; the stroke of the primary heat medium and the secondary heat medium is too short, and the secondary heat medium is basically in the static heating in the volume tank, so heat transfer cannot be realized Convective heat transfer in science, so the utilization rate of heat medium is extremely low, only about 50%, which wastes a lot of available heat and increases the cost. The volume utilization rate is not high, and there are dead water areas, the water ou...
