Embodiment 1

[0053] Such as figure 1 and figure 2 As shown, the air heat exchanger 100 of this embodiment includes a plurality of heat exchange channels 1, and each heat exchange channel 1 has an inlet and an outlet, so that the air enters the heat exchange channel 1 through the inlet, and the air after heat exchange passes through the outlet. flow out.

[0054] The plurality of heat exchange channels 1 include first heat exchange channels 11 and second heat exchange channels 12 distributed alternately, and the air in adjacent first heat exchange channels 11 and second heat exchange channels 12 performs heat exchange. Such as figure 1 and figure 2 As shown, each first heat exchange channel 11 is provided with a heat exchange fin 111 , and the heat exchange fin 111 is fixed on the side wall of the first heat exchange channel 11 . Specifically, the front and rear side walls of the first heat exchange channel 11 are respectively provided with a plurality of protrusions 112, and each pro...

Embodiment 2

[0058] The air heat exchanger 100 of this embodiment includes a plurality of heat exchange channels 1, each heat exchange channel 1 has an inlet and an outlet, so that air enters the heat exchange channel 1 through the inlet, and the air after heat exchange flows out from the outlet.

[0059] The plurality of heat exchange channels 1 include first heat exchange channels 11 and second heat exchange channels 12 distributed alternately, and the air in adjacent first heat exchange channels 11 and second heat exchange channels 12 performs heat exchange. Each heat exchange channel 1 is defined by a metal plate which is folded and fixed. Fold the metal plate and then fix it to form a heat exchange chamber with an opening on one side, and then set a through hole on the side wall of the heat exchange chamber facing the opening to process and form the heat exchange channel 1, the opening and the through hole Separately define entrances and exits.

[0060] Each first heat exchange chann...

Abstract

The invention discloses an air heat exchanger and a clothes dryer. The air heat exchanger comprises a plurality of heat exchange channels; each heat exchange channel is equipped with an inlet and an outlet; the heat exchange channels comprise first heat exchange channels and second heat exchange channels which are distributed in a staggered mode; air in every first heat exchange channel exchanges heat with air in the adjacent second heat exchange channel; and at least one heat exchange channel is defined by folding and folding one metal plate. According to the air heat exchanger disclosed by the invention, sealing property of heat exchange channels is favorably improved, the problem that air moves between every two adjacent heat exchange channels due to the fact that a glue bonding and fixing mode is adopted in the prior art is avoided, and heat exchange efficiency of the air heat exchanger is favorably improved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an air heat exchanger and a clothes dryer. Background technique [0002] Air heat exchangers are often used to cool and dry air to remove water vapor in humid air. They are widely used in air conditioning. The main principle is condensation dehumidification. The principle of condensation dehumidification is to cool the humid air below the dew point temperature. , to condense the water vapor in it, remove the condensed water and then heat to maintain the required relative humidity. The performance of the heat exchanger directly affects the treatment effect of the humid air. In the related art, the air heat exchanger includes multi-layer heat exchange channels, and the multi-layer heat exchange channels are bonded with glue, and the glue joints are poorly sealed, which easily leads to cross-air flow between two adjacent heat exchange channels, reducing air flow. hea...
