A kind of fin and condenser
Technical field
The present invention relates to a kind of fin and condenser, be used for the exchange heat of condensing type laundry dryer circulating current and extraneous air-flow.Adopt the venetian blind type fin, on air-flow direction, effectively increased the air side coefficient of heat transfer, and increased the air side heat exchange area, thereby improved heat exchange efficiency.
Background technology
Publication number is that the application for a patent for invention prospectus of CN1637204A (application number is 200410104991.4) discloses the technical scheme of a kind of " dryer and condenser assembly thereof " by name, describes prerequisite structure of condenser and function thereof in this scheme in detail.In order to strengthen, be built-in with fin at the room air circulation passage, to increase heat exchange area in the exchange heat between circulating air inlet hole and the room air circulation passage (the heat exchange air channel that corresponding the present invention hereinafter addresses); This fin is wavy extension on the direction vertical with heat exchange air channel airflow direction, form some air-flows slit.Yet the sidewall in the air-flow slit of existing fin is continuous, room air is limited in each air-flow slit flows the heat exchange weak effect.And the technical scheme of and the relevant heat exchange fin that relate to disclosed as ZL03218964.8 Chinese invention patent specification (Granted publication number for CN2624158Y), strengthened the effect of heat exchange from different angles, but these schemes are used for poling formula condenser and evaporimeter more, being circulatory mediator (as various refrigerants) flows in the vertical poling of the heat exchange fin that be arranged in parallel with multi-disc, room air can be subjected to stopping of poling during fluid interchange between heat exchange fin, the pressure loss is bigger, and since the flow area of the circulation air path of this condenser and evaporimeter much smaller than the flow area in heat exchange air channel, substantially the requirement that equates with the flow area of the condenser heat exchanging air channel of above-mentioned dryer and circulation air path differs very big, so they are difficult to be applied on the condenser of dryer.In addition, existing fin, peak, the paddy of bridge shape bar chip architecture partly are the plane, and this kind structure needs punching out to form, and not only heat exchange efficiency is low, and simultaneously, inconvenience is made; And the structure of cracking on fin individually then distributes in a jumble because of the slit, and same inconvenience is made.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome heat exchange weak effect, the inconvenient defective of making that prior art exists, and a kind of new fin and condenser are provided.For this reason, the present invention is by the following technical solutions:
A kind of fin is wavy some air-flows slit that extends to form, and it is characterized in that offering some groups of joint-cuttings on the sidewall in described air-flow slit, and the edge perk that every group of joint-cutting is positioned at airflow downstream forms the air port towards updrift side in the surface of place sidewall; Face mutually on the same sidewall between two groups of joint-cuttings and maintain the group spacing, the size of this group spacing be the air-flow slit 2-5 doubly.Can make an air-flow part change direction like this, a part flows to the place ahead, makes the resistance of air-flow moderate, and Uniform Ventilation improves heat exchange efficiency.
As the further of above-mentioned fin technical scheme improved and replenish, the present invention also comprises following additional technical feature:
