Abstract

The invention relates to a foam metal fin with irregular disturbance holes for a parallel flow heat exchanger. The metal fin (4) is made of a foam metal; the metal fin (4) is further provided with through holes (5) which are distributed at intervals and used for enhancing the fluidity of a fluid in the fin, wherein the area ratio of the through holes (5) to the internal irregular disturbance holes (401) of the metal fin (4) ranges from 15 to 50 times. Due to the adoption of the technical scheme, the maximum advantage of the foam metal fin is that the heat exchange coefficient of the heat exchanger can be increased as the foam metal with the irregular disturbance holes is taken as the fin of the heat exchanger, and the through holes which are distributed at intervals and formed in the foam metal fin are capable of effectively reducing the flow resistance of the fluid and improving the heat exchange efficiency of the heat exchanger.

Description

A kind of for parallel-flow heat exchanger the foam metal fin with irregular disturbance hole
Technical field
The present invention relates to heat-exchange apparatus part technical field, refer more particularly to a kind of for parallel-flow heat exchanger the foam metal fin with irregular disturbance hole.
Background technology
Metal fin is as a kind of heat exchange element, conventionally by being sleeved on the heat exchange efficiency that improves heat exchanger on the heat exchanger tube surface in heat exchanger.But traditional fin that existing parallel-flow heat exchanger is used, is generally the combination that flake structure or thin slice add shutter, not only poor rigidity of this version, and also heat exchange area is limited, and the coefficient of heat transfer of whole heat exchanger is not high.
Foam metal is as the very large porous material of a kind of specific area (surface area in unit volume), due to foam metal complex structure, when cross-ventilation, can effectively utilize the 3 D complex of air-flow to flow, increase the disturbance of air current flow, increase turbulent flow, improve the coefficient of heat transfer, can effectively strengthen heat transfer effect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide foam metal that a kind of employing that improves heat exchange efficiency has through-hole structure spaced apart as the metal fin for parallel-flow heat exchanger.
For achieving the above object, technical scheme provided by the present invention is: a kind of for parallel-flow heat exchanger the foam metal fin with irregular disturbance hole, described metal fin is made by foam metal, and this metal fin is also provided with the through hole for increasing fin inner fluid mobility spaced apart, wherein the ratio of the irregular disturbance hole area of this through hole and metal fin inside is between 15~50 times.
Further, described foam metal is the one in foam copper or foamed aluminium.
Further, described via arrangement form is even spaced apart or staggered one in spaced apart.
Further, described through hole is the one in circle or regular polygon.
The present invention is adopting after such scheme, its great advantage is by adopting the fin as heat exchanger with the foam metal in irregular disturbance hole, can improve the coefficient of heat transfer of heat exchanger, and the through-hole structure spaced apart that is provided with of foam metal fin can effectively reduce the flow resistance of fluid, improve the heat exchange efficiency of heat exchanger.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention is provided with equally distributed circular hole.
Fig. 2 is that the present invention is arranged on the schematic perspective view on parallel-flow heat exchanger.
Fig. 3 is that the present invention is arranged on the structural representation on parallel-flow heat exchanger while being provided with the circular hole being interspersed.
Fig. 4 is the structural representation that the present invention is provided with the circular hole being interspersed.
Fig. 5 is the structural representation that the present invention is provided with the square hole being interspersed.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described:
Shown in accompanying drawing 1, described metal fin 4 is made by foam metal, this foam metal can be the one in foam copper or foamed aluminium, on described foam metal fin 4, be also provided with through hole 5, the arrangement form of this through hole 5 can be evenly spaced apart or staggered one in spaced apart, and this through hole 5 is the one in circle or Else Rule polygon, not to be limited, wherein the ratio of the area in the irregular disturbance hole 401 of through hole 5 and metal fin 4 inside is between 15~50 times.Wherein, the area of through hole 5 must be within a rational scope with the ratio of the area in flow-disturbing hole 401.When ratio between two shows more greatly that fluid flows through heat exchanger, resistance is less, and flow is larger, but the disturbance of fluid is less, and the coefficient of heat transfer diminishes; Ratio between two is less, and to show that fluid flows through the resistance of heat exchanger larger, and flow is less, but the disturbance of fluid increases, and it is large that the coefficient of heat transfer becomes; Therefore for balanced flow and the coefficient of heat transfer, must make the ratio of the area of through hole 5 and the area in flow-disturbing hole 401 change within a rational scope, comparatively reasonable when ratio between two is between 15-50 through experimental test and theory analysis.Accompanying drawing 4 and accompanying drawing 5 are respectively and are provided with the circular hole that is interspersed and the foam metal structural representation of square hole.
Embodiment mono-:
Shown in accompanying drawing 2, in figure, be that the foam metal fin 4 that is provided with circular hole evenly spaced apart is arranged on the structural representation on parallel-flow heat exchanger.The first header 1 and the second header 2, have the effect of set cold-producing medium, and side plate 7 is for supporting and protect the effect of whole heat exchanger structure, and blocking cap 10 is for sealing header.Wherein cold-producing medium is by entering in inlet tube 8, inflow heat exchanger, through the separation shunting action of dividing plate 6, cold-producing medium flows in flat tube 3 uniformly, air flows in flat tube 3 outside metal throuth hole foams, behind each position of the heat exchanger of flowing through, through the afflux effect of the first header 1 and the second header 2, cold-producing medium is through outlet 9 outflow heat exchangers.Due to the scrambling in foam metal inside configuration disturbance hole 401, increased the disturbance of gas flow, be conducive to fully contacting of the disturbance of gas flow and air and foam metal fin, increase heat exchange efficiency.And owing to offering equally distributed through hole 5 on foam metal fin 4, through hole 5 can effectively solve the flow resistance problem running into when air in heat exchanger flows in the disturbance hole 401 of metal fin 4 inside, by having through hole 5 in the centre position of foam metal fin 4, can reduce the flow resistance of air, suitably accelerate speed air flow, improve heat exchange efficiency.
Embodiment bis-:
Shown in accompanying drawing 3, in the present embodiment, be arranged on through hole 5 that the foam metal fin 4 on parallel-flow heat exchanger is provided with for staggered spaced apart, other structure is all consistent with the structure in embodiment mono-.Compare the through-hole foamed metal fin 4 even spaced apart being provided with in embodiment mono-, through hole 5 density in this embodiment on foam metal fin 4 are larger, and heat transfer effect is more obvious.
The examples of implementation of the above are only the present invention's preferred embodiment, not with this, limit practical range of the present invention, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
