Description
Technical field
The present invention relates to technical field of refrigeration equipment, particularly to the direct-cooled plate-condenser in a kind of new high-efficiency back.
Background technology
At present, plate-condenser with its preferable heat dispersion and simple mounting process at a lot of refrigerators, quilt on refrigerator
It is widely used.Plate-condenser, is typically secured on the back of refrigerator, is connected with press, and the high-temperature exhaust air of compressor is through supercool
Condenser dispels the heat.Traditional plate-condenser, primary structure be secure in the both sides of condensing tube many heat radiation steel wires, on the one hand this
The heat radiation limitation planting structure is big, and the heat dissipation capacity in the unit interval is little, and temperature is high, easy impaired user；On the other hand steel wire master
If being fixed by the way of welding, thus causing and there is on condensing tube multiple solder joint, easily causing and condensing tube is made
Become damage, can be leaky on condensing tube time serious, thus condenser itself is caused serious quality problems.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide the direct-cooled plate-condenser in a kind of new high-efficiency back, at this knot
Not having any solder joint in structure, area of dissipation is big, good refrigeration effect.
Realize technical scheme as follows:
The direct-cooled plate-condenser in new high-efficiency back, including S type coil pipe, and the spiral fin being wrapped on coil pipe,
The radius bend of described coil pipe is 7.5-60mm, and the pitch on fin is 2-12mm, between root and the end of fin of fin
A length of 1-20mm.
Further, described coil pipe is made up of a continuous roundabout bending of straight tube.
Further, described fin is L-type structure.
Further, described fin is aluminium strip fin or sheet iron strip fin or copper strips fin.
Further, head end and the end of described fin is fixedly clamped on coil pipe by fixture.
Further, described fin or be planar configuration or for wave structure or for plane and the hybrid knot of wave
Structure.
The present invention also provides for a kind of refrigeration plant, including the above-mentioned direct-cooled plate-condenser in new high-efficiency back.
Have employed above-mentioned scheme, the fin of the present invention is spirally wound on pipe fitting by a metal tape, it is not necessary to appoint
What fixed form (such as welding) fin just firmly can be connected with pipe fitting, prevents pipe fitting and fin from sustaining damage, it is ensured that pipe fitting
Normal use with fin；Certain area of helical fin but do not take up space, which adds the area of dissipation of condenser,
Condenser compared to existing technology, the area of dissipation of the present invention can improve 20%-60%, is effectively improved its refrigeration effect
Really.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is the attachment structure schematic diagram of fin and coil pipe；
Fig. 3 is the another kind of structure of fin；
Detailed description of the invention
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1 and Fig. 2, the direct-cooled plate-condenser in new high-efficiency back, make including by a continuous roundabout bending of straight tube
S type coil pipe, and the spiral fin being wrapped on coil pipe, fin can be perpendicular with coil pipe, it is also possible to is formed certain
Angle, such as 90 °, 85 °, 80 ° etc., in order to ensure that fin can firmly be clamped on coil pipe, by head end and the end of fin
It is fixedly clamped on coil pipe by fixture.In order to ensure that on condenser, result of ventilating heat dissipation is appropriate unaffected, on fin
Pitch D is set to 2-12mm；Originally experiencing due to fin, rate and fin distance, difficulty of processing are stretched in material edge, product space volume will
The impact asked etc., fin height L is set to 1-20mm；Coil pipe radius bend 7.5-30mm.The area of dissipation of the present invention is than biography
The area of dissipation of the steel wire of system improves 20%-60%, and radiating effect significantly improves.The monomer volume reducing condenser is had significantly
Effect, improves the safety of product.
Certainly, fin is possible not only to as vertical bar shaped structure, it is also possible to for L-type structure (such as Fig. 3).
The form of fin can have multiple, or be planar configuration or for wave structure or for plane and wave hybrid
Structure.
The present invention also provides for a kind of refrigeration plant, including the above-mentioned direct-cooled plate-condenser in new high-efficiency back.
In order to obtain good refrigeration and be easily installed, as a example by sheet iron strip fin, it is provided that following three kinds of shapes
The condenser of formula:
Embodiment 1, radius bend R of coil pipe is 30mm, and pitch D on fin is 5mm, the root of fin and the end of fin
Length L between portion is 8mm.
Embodiment 2, radius bend R of coil pipe is 30mm, and pitch D on fin is 8mm, the root of fin and the end of fin
Length L between portion is 12mm.
Embodiment 3, radius bend R of coil pipe is 30mm, and pitch D on fin is 10mm, the root of fin and fin
Length L between end is 17mm.
As a example by aluminium strip fin, it is provided that the condenser of following two form:
Embodiment 4, radius bend R of coil pipe is 30mm, and pitch D on fin is 6mm, the root of fin and the end of fin
Length L between portion is 10mm.
Embodiment 5, radius bend R of coil pipe is 30mm, and pitch D on fin is 9mm, the root of fin and the end of fin
Length L between portion is 14mm.
Certainly, fin also can be selected for copper strips fin.
In the present invention pitch on fin can not excessive can not be too small, when pitch is too small, the heat between fin cannot and
Time disperse, heat is concentrated and is gathered, and condenser can cause time serious the effect made a false countercharge, cause condenser to lose the work of refrigeration
With；When pitch is excessive, its area of dissipation does not become big relative to existing wire tube condenser, diminishes on the contrary, its effect of freezing
Fruit does not the most get a promotion, and not having is practicality.
In the present invention, the length between fin upper fin root and fin end portion first has to ensure at 1-20mm, such condenser
Radiating effect is the most effective, if less than 1mm, its area of dissipation is the least, and effect is the most inconspicuous；Owing to fin is to be spirally wound on
On coil pipe, it is contemplated that the ductility of fin, being found through experiments, when the L of ferrum fin is arranged on 20mm, its surface has produced
Crackle, i.e. product have been scrapped, so L is impossible (aluminium strip fin cracks when 15mm) more than 20mm.
