Abstract
The utility model relates to a CMI threading cooling fin heat exchange component between gases and liquid, in particular to a heat exchange component for an air and water cooler on an alternating current-direct current motor, which belongs to the technical field of a heat exchange component. The CMI threading cooling fin heat exchange component is characterized in that pore flanged edges, an annular window, a bridge-shaped window and corrugated trimmed edges are arranged on an entire cooling fin. The CMI threading cooling fin heat exchange component can effectively reduce the influence of thermal resistance at the edges of laminar flow, improve the utilization ratio of space and reduce the wind resistance and the pressure drop. By comparing the CMI threading cooling fin heat exchange component with the copper and aluminium compound finned tube heat exchange component, the coefficient of thermal transmission is improved by 30.2 percent; the wind resistance and the pressure drop are reduced by 10.3 percent.
Description
Technical field
The utility model relates to the heat exchange element between a kind of CMI sheet assemble fin gas and the liquid, specifically as the heat exchange element of air/water cooler on the AC/DC motor, belongs to the heat exchange element technical field.
Background technology
In prior art, the heat exchange element of air/water cooler adopted pipe with wound fin, around reed pipe and copper aluminum composite fin tube etc.Before using the sheet assemble heat exchange mode, employing be the copper aluminum composite fin tube.Be by behind aluminum pipe and the copper pipe fit, on special milling train, make aluminum pipe shut out the screw-type fin, with the copper pipe at center tight the contact arranged simultaneously.Copper aluminum composite fin tube thermal transmission coefficient is 1.5m/s in water speed, and wind speed is 54W/ (m during for 4m/s
2* ℃).The windage pressure drop is for 40Pa (single).
Summary of the invention
The purpose of this utility model is to design seeks a kind of CMI sheet assemble fin, both can improve thermal transmission coefficient, can reduce the requirement of windage pressure drop again.
According to the technical scheme that the utility model provides, it mainly on the cooling fin of integral body, is provided with pore flange, ring-like window, bridge shape window and ripple respectively continuously and cuts edge, and is the circulating direction of air.
Compared with the prior art the utility model has the following advantages:
The utility model can effectively reduce the thermal resistance influence of wake boundary owing to adopted novel structure, has improved space availability ratio, has reduced the windage pressure drop.Compare with copper aluminum composite fin tube heat exchange element, thermal transmission coefficient is 1.5m/s in water speed, and wind speed is 70.3W/ (m during for 4m/s
2* ℃); The windage pressure drop is for 35.9Pa (single); Thermal transmission coefficient can improve 30.2%, and the windage pressure drop can reduce by 10.3%.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure A～A cross section view.
Fig. 3 is the utility model structure B～B cross section view.
Fig. 4 is the utility model ripple side cut structural representation.
Embodiment
Following the utility model will be further described in conjunction with the accompanying drawings:
As shown in Figure 1: on the cooling fin of integral body, be provided with pore flange 1, ring-like window 2, bridge shape window 3 and ripple continuously and cut edge 4.Be 8 rounds among the figure, row's number can be adjusted when the punching press by designing requirement and change.Be the length direction of cooling fin laterally, cooling fin length is with the requirement of cooler preseting length shearing when the punching out.
The effect of pore flange 1, the first plays the role of positioning to the spacing of cooling fin, and it two is joint faces as cooling fin and cooling water pipe expanded joint; The effect of ring-like window 2, bridge shape window 3 mainly is the action of turbulent flow to air-flow, reduces the thermal resistance influence of wake boundary, and the effect that increases heat exchange area is also arranged in addition.Ripple cuts edge 4, to the edge of cooling fin is smooth repair is arranged, and has guaranteed to install that there is identical regular spacing at the edge between the cooling fin of back.
The direction of arrow is the circulation of air direction among the figure, and air communication is crossed the clearance space of adjacent two cooling fins.
The utility model is installed: adopt the mode of heat exchanger fin and heat exchanger tube expanded joint, the quantity of cooling fin is by the design decision of cooler.Expanded joint carries out on specialized apparatus.
Claims (1)
1, a kind of CMI sheet assemble fin comprises whole cooling fin, it is characterized in that the cooling fin of integral body is provided with pore flange (1), ring-like window (2), bridge shape window (3) and ripple side cut (4).
