Description
Technical field
The present invention relates to technical field of heat exchange equipment, more particularly to a kind of inserted sheet fin and heat exchanger.
Background technique
When micro-channel heat exchanger is applied to heat pump system at present, according to the needs that fin drains, fin structure is inserted sheet knot
Structure.
Due to needing to consider the heat exchange property of non-frozen condition, the spacing needs between two flat tubes are as small as possible, lead to wing
Piece efficiency is too high, and the fin temperature between frozen condition, two flat tubes is too low to lead to heat exchanger surface frosting quickly, and windage becomes
Greatly, heat exchange property sharply declines.
Summary of the invention
The object of the present invention is to provide a kind of inserted sheet fin and heat exchangers, can make fin along air inlet side under frozen condition
To formation temperature gradient, fin front end frosting degree is reduced, improves heat exchanger heat exchange property.
In order to solve the above technical problems, providing a kind of inserted sheet fin, including fin sheet as one aspect of the present invention
Body, fin body spaced first flat tube slot and the second flat tube slot along its length, the depth of the first flat tube slot is less than
The depth of two flat tube slots.
The depth of inserted sheet fin of the invention, the first flat tube slot and the second flat tube slot is different, therefore, can be along air inlet direction
Formation temperature gradient, when heat exchanger is in frozen condition, can reduce fin front end to reduce fin front end heat exchange amount
Heat exchange amount reduces the frosting velocity of heat exchanger surface, avoids windage problems of too caused by frosting, guarantees the heat-exchange performance of heat exchanger
Energy.
