Abstract

The invention discloses a kind of air cooling fin evaporator, it includes fin, and the upper-lower position of fin is correspondingly arranged on poling hole, be provided with airflow hole around fin poling hole, and the poling hole is shaped as geometry shape.The technical program is equipped with airflow hole on fin, accelerates the gaseous exchange between fin.The present invention has the following effects that:Stomata on fin accelerates the convection current between air between fin, makes temperature more uniform, and heat transference efficiency is improved, and accelerates refrigerating speed, improves refrigeration.

Description

A kind of air cooling fin evaporator
Technical field:
The present invention relates to air cooling fin evaporator, it is particularly well-suited to be used on household electrical appliances refrigerating field.
Background technology:
Air cooling fin evaporator, fin is arranged on pipe, wind is cooled down during evaporator refrigeration and is circulated from fin clearance, Carry out heat exchange.Fin used by current evaporator fin, more using sheet metal, punching, poling on sheet metal, refrigerant is in pipe Interior flowing, the hole on fin is only used for poling or wears heater strip use, and other positions do not have hole.This fin structure, causes air In circulation, convection current is not smooth between the air between fin of not going together, and non-uniform temperature, heat transference efficiency is low, in turn results in refrigerator Refrigerating speed is slower, and refrigerating capacity is poor, and power consumption is big.Existing evaporator fin, on fin except poling or wear heater strip use Hole, does not have hole.In evaporator operation, air-flow flows to the other end from one end by fin clearance, and air flow between fin Not smooth, non-uniform temperature, heat transference efficiency is low, in turn results in Refrigeration Speed for Refrigerator slower.
The content of the invention:
Task of the invention is to propose that one kind makes evaporator fin in refrigeration work, and air-flow is more readily formed turbulent flow, makes Temperature is more uniform, accelerates a kind of air cooling fin evaporator of refrigeration.
Task of the invention is done in such a way that a kind of air cooling fin evaporator, and the upper-lower position of its fin is correspondingly arranged There is poling hole, worn with fin by poling hole energy multi-disc thereon, fin poling is provided with airflow hole around hole, and its feature exists In:The surrounding in one poling hole of same fin is provided with airflow hole, and the surrounding in another poling hole is smooth metal, airless Hole, rotates 180 ° of sequences and installs when evaporator fin is assembled according to the airflow hole in adjacent fins.
The present invention has the following effects that:The technical program is equipped with airflow hole on fin, accelerates the gaseous exchange between fin. Stomata on fin accelerates the convection current between air between fin, and air-flow is more readily formed turbulent flow, makes temperature more uniform, and heat is passed Efficiency raising is passed, accelerates refrigerating speed, improve refrigeration.
Brief description of the drawings:
Fig. 1 is the structural representation of evaporator fin of the present invention;Fig. 2 is the structural representation that the fin first half is provided with airflow hole Figure;Fig. 3 is the structural representation that fin lower half is provided with airflow hole;Fig. 4 is evaporator fin mounting structure schematic diagram.
Drawing explanation:1st, evaporation tube, 2, fin, 3, airflow hole, 4, upper poling hole, 5, lower poling hole.
Specific embodiment:
Embodiment is described in detail with reference to the figures above, embodiment one, referring to shown in Fig. 1 and Fig. 2 is provided with fin 2 and wears The poling hole of evaporation tube 1, the arrangement in poling hole is to be correspondingly arranged up and down, and the shape in the poling hole can be arranged to geometric form Shape, such as circular, square or rhombus, furtherly:As a example by above poling hole 4 is for circle, gas is equipped with around upper poling hole Discharge orifice 3, the lower surrounding of poling hole 5 that fin is correspondingly arranged below is smooth metal covering, furtherly:Worn under below fin The surrounding of pore 5 is not provided with airflow hole.
As shown in figure 3, be equipped with airflow hole around the lower poling hole 5 that is provided below of fin 2, fin set above on wear The surrounding of pore 4 is smooth metal covering, that is to say, that:The surrounding in upper poling hole is not provided with airflow hole.
Above-described fin mounting structure schematic diagram is shown in Figure 4, and fin is installed with evaporation tube, wing in upper and lower poling hole Wearing with that can be assembled with multi-disc for piece, 180 ° of sequence installations can be rotated during assembling according to the airflow hole on every fin.After assembling Evaporator fin on airflow hole be the passage for interpenetrating and forming gaseous exchange, the stomata on fin accelerates empty between fin Convection current between gas, air-flow is more readily formed turbulent flow, the convection current between air between fin is accelerated, so as to improve refrigeration.
