Stacking type heat exchanger

Abstract

Disclosed is a superposed heat exchanger, comprising multiple fins (1) superposed together, two opposing sides of each fin (1) bending upwards, fitting with the fin (1) above to form a ventilating air duct, and adjacent fins (1) being arranged in a longitudinally and transversely staggered way so as to create mutually independent transverse air ducts and longitudinal air ducts separated top to bottom. The heat exchanger is created of multiple superposed fins arranged in a longitudinally and transversely staggered way, uses a plastic material, is simple to shape, and the thickness thereof can be controlled so that the heat exchanger can be made very thin. The number of fins can be increased in an effective space, which can increase the heat-dissipation area and improve heat-exchange efficiency. Using an insert pin (4), an insert groove (5) and a curved turn-up edge (7) to position and connect, the longitudinally and transversely staggered arrangement can be directly superposed with no need for other connecting components, and the positioning thereof is simple and precise.

Description

technical field [0001] The invention relates to the field of clothes drying, in particular to a superimposed heat exchanger for condensing steam in a clothes dryer or an integrated washing and drying machine. Background technique [0002] With the continuous upgrading and optimization of energy efficiency standards in the household appliance industry, more and more users have begun to pay attention to the energy efficiency parameters of products, and energy conservation and environmental protection have become the development direction of the industry. [0003] Therefore, the drying capacity of the washer-dryer with three-in-one washing, washing and drying is also upgraded along with the upgrading of the industry. In the drum type washer dryer, during the drying process, the energy not only evaporates the water in the clothes into steam, but also continues to condense the evaporated steam into water vapor. [0004] At present, there are three forms of condensation methods i...

AI Technical Summary

Problems solved by technology

Disadvantages: The machine needs continuous water intake and cooling during operation, and the water consumption is large

Disadvantages: high cost, expensive, not conducive to promotion

Generally limited by the space of the washing machine, two sets of heat dissipation paths can be made at most. The production cost of aluminum alloy materials is high, and the heat dissipation effect is limited by the production process of aluminum alloy sheets. The contact area between steam and condenser is small, which is not conducive to steam condensation.
