Abstract
A metal special pipe for heat exchangers comprises a pipe body, and is characterized in that concave pits are arranged on the pipe wall of the pipe body at intervals. The metal special pipe for heat exchangers is scientific in design and simple and reasonable in structure, the concave pits arranged on the pipe body at intervals can form symmetrical reinforcing ribs which can not only increase strength of the pipe body but enlarge radiating area of the pipe wall. The metal special pipe is applied to exchanging heat, and laminar flows are changed into turbulent flows when heat conducting fluid flows through the metal special pipe, thereby increasing the radiating efficiency by 15% on conditions of identical area. From another perspective, the metal special pipe can directly reduce material usage by 15% on the condition of having identical radiating efficiency, thereby greatly reducing product cost.
Description
Technical field
The heat exchanger that the utility model relates to, especially a kind of heat exchanger metal shaped tube that is used for.
Background technology
The traditional heat-dissipating device is made of the multilayer heat exchanger tube usually, and the heat exchanger tube that is adopted is generally the copper pipe of good heat conductivity.But copper pipe price height, the radiator manufacturing cost is also higher.For reducing the radiator manufacturing cost, a lot of radiators have adopted cheap aluminium matter pipe to substitute the high copper pipe of price.Yet common aluminum pipe will reach the sink-efficiency that design needs, the essential area of dissipation that increases, and the long axis direction width that so just needs to increase aluminum pipe quantity or radiator tube guarantees required radiating efficiency.Increasing the major axis width can be because of the lower radiator intensity that weakens of the intensity of aluminum pipe own, if increase the number of plies of radiating tube, the relatively poor brazing characteristics difference of aluminium then can cause its leakage weldering phenomenon to increase and influence quality.Therefore the application of common aluminum pipe on radiator is subjected to certain limitation.
The utility model content
Technical problem to be solved in the utility model is to remedy the defective that above-mentioned prior art exists, and proposing a kind ofly both can increase tubing unit's area of dissipation, can increase the heat exchanger metal shaped tube of tubing intensity again.
Technical problem of the present utility model is solved by the following technical programs.
This heat exchanger metal shaped tube comprises: body.
The characteristics of this heat exchanger metal shaped tube are: be interval with the pit that caves on the tube wall of described body.
Technical problem of the present utility model is solved by following further technical scheme.
Pipe face around body is provided with some linearly spaced apart pits along axis.
Described body is flat type pipe or round tube.
Be provided with two linearly spaced apart pits along axis respectively on the two pipe faces up and down of described flat type pipe.
Be distributed on the spacer L 〉=5mm of each pit on the body tube wall.
Described pit is circular pit or oblong pits.
Described body is aluminum pipe or aluminium-alloy pipe.
The beneficial effect that the utility model is compared with the prior art is:
This heat exchanger metal shaped tube design science, simple and reasonable for structure, the pit that is provided with at interval on the body can form the reinforcement of symmetry, and it not only can increase the intensity of body, can increase the area of dissipation of tube wall simultaneously.This metal shaped tube is applied to heat exchange, when heat-transfer fluid passes through, can make original laminar flow become turbulent flow, under situation with homalographic, can make radiating efficiency improve 15%, from another angle, in the situation of same radiating efficiency, directly can reduce the use of material 15%, lower the cost of product greatly.And under the situation for single use, can under the situation that does not increase the material wall thickness, improve the intensity of body, can make wideer that tubing does, enlarge the scope of application of aluminum pipe, thereby make aluminium in the heat exchange industry, obtain using more widely.
Description of drawings
Fig. 1 is the structural representation of heat exchanger metal shaped tube.
Fig. 2 is that the A-A of heat exchanger metal shaped tube shown in Figure 1 is to cross-sectional view.
The specific embodiment
Embodiment: can be clear that from Fig. 1 and Fig. 2 this is a kind of heat exchanger metal shaped tube of flat type, it is made of aluminium alloy flat type pipe 1, be provided with two linearly spaced apart pits 2 along axis respectively on two tube walls up and down of aluminium alloy flat type pipe 1, the spacer L of each pit 2 is 5mm.
This heat exchanger metal shaped tube can adopt welding fabrication, and its method is: before product forms welding, form twice pit 2 on the surface of raw material aluminium strip by mold high speed earlier, form aluminum pipe by HFI welding again.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; and performance or purposes are identical, then should be considered as belonging to the protection domain that the utility model is determined by claims of being submitted to.
