Abstract
Provided is an air cooler. The air cooler comprises a shell (5), wherein baseplates (3) are respectively installed on both sides of the shell in sealed mode, a plurality of pieces of heat exchange tubes (6) stretch out from the space between the baseplates, heat exchange tubes (6) is connected with baseplates in sealed mode, a water inlet (4) and a water outlet (9) are installed on the wall of the shell, a front end cap (2) and a rear end cap (7) are respectively connected with the two ends of the shell, an air inlet (1) is arranged in the front end cap (2), an air outlet (8) is installed in the rear end cap. The air cooler is characterized in that the tube wall of the heat exchange tube is corrugated structure along the axial direction. Due to the fact that the tube wall of the heat exchange tube is corrugated structure along the axial direction, and the gas is in a state of turbulence while flowing. The gas in a state of turbulence while flowing is beneficial for heat changing between the gas in the heat exchange tube and the fluid in the outer of the heat exchange tube, and improves the heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of aerial cooler, relates to specifically a kind of cooler that reduces air themperature with cooling fluid.
Background technology
Existing aerial cooler comprises that housing, housing two ends are provided with support plate, be installed with the heat exchanger tube that gas passes through on the support plate, housing and support plate consist of a water tank, in housing, inject cooling fluid during use, need the gas of cooling from heat exchanger tube, to flow through, the heat of gas carries out heat exchange by heat exchanger tube and cooling fluid, and the temperature of gas is reduced.Existing heat exchanger tube is generally cylindrical conduit, gas wherein flows with the form of laminar flow, radial direction gas at pipeline does not flow, the temperature of heat exchanger tube center is different from the temperature at tube wall place during heat exchange, the temperature at tube wall place is lower, because gas does not flow at the radial direction of pipeline, so that the efficient of heat exchange is lower.
The utility model content
For the deficiencies in the prior art, the technical problems to be solved in the utility model provides the high aerial cooler of a kind of heat exchange efficiency.
The technical scheme of the technical problem that the utility model solves is: this aerial cooler comprises housing 5, two ends in the housing seal respectively is equipped with support plate 3, some heat exchanger tubes 6 stretch out between the support plate, heat exchanger tube 6 is tightly connected with support plate, be provided with water inlet pipe 4 and outlet pipe 9 on the wall of housing 5, the two ends of housing 5 are connected with respectively drive end bearing bracket 2 and rear end cap 7, be provided with air inlet 1 on the drive end bearing bracket 2, be provided with gas outlet 8 on the rear end cap 7, it is characterized in that the tube wall of described heat exchanger tube 6 axially is wave structure along it.
The tube wall of heat exchanger tube axially is undulatory structure along it, so that gas is turbulence state when flowing in pipeline, the gas at pipeline center place can roll to the tube wall place, the gas at tube wall place can roll to pipeline center and locate, the radial temperature of gas in heat exchanger tube is substantially equal like this, be conducive to the heat exchange between the outer liquid of gas in the heat exchanger tube and heat exchanger tube, thereby improve heat exchange efficiency.Because tube wall is corrugated, compare with the heat exchanger tube of straight tube shape simultaneously, its contact area increase with gas also helps heat exchange.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The existing accompanying drawings specific embodiment of the present utility model.
Aerial cooler of the present utility model, comprise housing 5, two ends in the housing seal respectively is equipped with support plate 3, some heat exchanger tubes 6 stretch out between the support plate, and heat exchanger tube 6 is tightly connected with support plate, is provided with water inlet pipe 4 and outlet pipe 9 on the wall of housing 5, the two ends of housing 5 are connected with respectively drive end bearing bracket 2 and rear end cap 7, be provided with air inlet 1 on the drive end bearing bracket 2, be provided with gas outlet 8 on the rear end cap 7, it is characterized in that the tube wall of described heat exchanger tube 6 axially is wave structure along it.
Ripple can inwardly concave at straight tube on the tube wall of described heat exchanger tube, also can be outwardly on straight tube, for ripple on the tube wall of in the present embodiment heat exchanger tube easy to process adopts structure outwardly on straight tube, the height of ripple evagination is the wall thickness of straight tube, the spacing between the ripple be straight tube diameter 0.5-1.5 doubly.
The radical of heat exchanger tube is more than 2, can be according to specifically being determined by the flow of recuperated gas.
By test, in the situation that diameter is identical with length, the heat exchanger tube of wave structure with the heat exchanger tube of straight tube shape compare, its heat exchange efficiency can improve about 30%.
The course of work is, needs the gas of cooling to enter from the air inlet 1 on the drive end bearing bracket 2, and through heat exchanger tube, flow out the gas outlet 8 from rear end cap 7; Cooling fluid enters gas converting heat in housing and the heat exchanger tube by the water inlet pipe 4 on the housing 5, discharges through outlet pipe 9 again.
Claims (1)
1. an aerial cooler comprises housing (5), two ends in the housing seal respectively is equipped with support plate (3), some heat exchanger tubes (6) stretch out between the support plate, heat exchanger tube (6) is tightly connected with support plate, be provided with water inlet pipe (4) and outlet pipe (9) on the wall of housing (5), the two ends of housing (5) are connected with respectively drive end bearing bracket (2) and rear end cap (7), be provided with air inlet (1) on the drive end bearing bracket (2), be provided with gas outlet (8) on the rear end cap (7), it is characterized in that the tube wall of described heat exchanger tube (6) axially is wave structure along it.
