Description
Technical field
The utility model relates to a kind of overlaying structures of heat exchange core fin.Belong to air-conditioning technical field.
Background technique
The working principle of sensible heat exchanger is: when product works, orthogonal thereto fork mode is flowed through respectively for indoor exhaust wind and fresh air
When heat exchange core, since two sidewind of splitter plate is there is the temperature difference, two strands of air-flows are presented phenomenon of Heat when passing through demarcation plate, draw
Play Exchange of apparent heat process.When summer operation, fresh air obtains cooling capacity from air conditioning air exhaust, reduces temperature；When winter operation, fresh air from
Air conditioning chamber's air draft obtains heat, and temperature increases.In this way, passing through the sensible heat transfer process of heat exchange core, allow fresh air from air conditioning air exhaust
It recovers energy.
Each fins set of existing heat exchange core is superimposed using two panels fin, a piece of to face directly, a piece of to have 45 ° of inclination angles,
Such overlaying structure has the following problems: air draught is when entering two adjacent fins group, a piece of fin only with angle
Guiding role is played, the resistance that air is subject to is big, and the air inlet air quantity that is averaged is small, to affect heat exchanger effectiveness.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of overlaying structures of heat exchange core fin.
Purpose of the utility model is realized as follows:
A kind of overlaying structure of heat exchange core fin, its main feature is that: it includes multiple fins sets being arranged side by side, and adjacent two
There is certain interval, each fins set includes the first fin and the second fin, and the first fin includes top between a fins set
Bending segment, the first straight section of the oblique section of the first of middle part and lower part, the second fin include second straight section on top, and the second of middle part is tiltedly
The third straight section of section and lower part；The bending angle of bending segment is 180 °, is formed after bending segment bending is protruded at the top of the second straight section
Opening in it is fixed；First oblique section and the second oblique section are inclined outwardly, and the two inclination angle is consistent and forms inverted V-shaped；First straight section with
Third straight section is parallel to each other.
Further, the first oblique section and the outside inclination angle of the second oblique section are 45 °.
Further, the distance between the first straight section and third straight section are equal to adjacent the distance between two fins sets.
Compared with prior art, the utility model has the beneficial effects that
A kind of overlaying structure of heat exchange core fin of the utility model, there are two the tilting sections of flare for a fins set tool, no
The size of air inlet is increased only, and each fin all has guiding role, i.e. a fins set is oriented to two sides, is reduced
Air drag, under the conditions of identical rotation speed of the fan, the air quantity of the utility model can at least improve 10%, improve heat exchange effect
Rate.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of the overlaying structure of heat exchange core fin of the utility model.
In figure:
First fin 1, bending segment 1.1, the first oblique section 1.2, the first straight section 1.3, the second fin 2, the second straight section 2.1, the
Two oblique sections 2.2, third straight section 2.3, air draught region 3, indoor air flow region 4.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
Referring to Fig. 1, the utility model relates to a kind of overlaying structures of heat exchange core fin, it includes multiple wings being arranged side by side
Piece group, has certain interval between two adjacent fins sets, and each fins set includes the first fin 1 and the second fin 2, and first
Fin 1 includes the bending segment 1.1 on top, and the first straight section 1.3 of the oblique section 1.2 of the first of middle part and lower part, the second fin 2 includes upper
Second straight section 2.1 in portion, the third straight section 2.3 of the second of middle part oblique section 2.2 and lower part.
The bending angle of bending segment 1.1 is 180 °, and the top of the second straight section 2.1 is protruded into after bending segment 1.1 is bent and formed
In opening, the two is fixed；
First oblique section 1.2 and the second oblique section 2.2 are inclined outwardly, and inclination angle is 45 °, and the two forms inverted V-shaped；
First straight section 1.3 is parallel to each other with third straight section 2.3.
The distance between first straight section 1.3 and third straight section 2.3 are equal to adjacent the distance between two fins sets.
Working principle:
Wherein, air draught region 3 is formed between two adjacent fins group；The first straight section 1.3 in the same fins set
Indoor air flow region 4 is formed between third straight section 2.3.
When summer operation, air obtains cooling capacity from air conditioning air exhaust and enters air draught region 3, and indoor exhaust wind enters the room gas
Region 4 is flowed, orthogonal thereto fork mode flows through heat exchange core progress heat exchange to the two respectively, so that indoor air temperature reduces；Winter fortune
When row, air obtains heat from air conditioning air exhaust and enters air draught region 3, and indoor exhaust wind enters the room flow area 4, the two point
Not orthogonal thereto fork mode flows through heat exchange core and carries out heat exchange, so that indoor air temperature increases.
The utility model, a fins set tool not only increase the size of air inlet there are two the tilting section of flare, and
Each fin all has guiding role, i.e. a fins set is oriented to two sides, reduces air drag, turns in identical fan
Under the conditions of speed, the air quantity of the utility model can at least improve 10%, improve heat exchange efficiency.
Test is compared with 120W heat exchange, under identical fans speed conditions, the air inlet of existing heat exchange core is flat
Equal air quantity is 800M3/ H, the air inlet of the utility model are averaged air quantity as 920M3/H。
In the above-described embodiments, exemplary description only is carried out to the utility model, but those skilled in the art are reading
Various repair can be carried out to the utility model in the case where not departing from the spirit and scope of the utility model after present patent application
Change.
