Abstract
The utility model relates to the technical field of heat exchangers for mechanical equipment, in particular to an efficient air-air heat exchanger. The efficient air-air heat exchanger is provided with an air housing, wherein a left tube plate and a right tube plate are mounted at two ends of the air housing; an air inlet is formed at the bottom center of the air housing; a left air outlet and a right air outlet are formed on two sides of the bottom of the air housing; a plurality of cooling tubes are arranged in the air housing; two ends of each cooling tube are supported on the left and the right tube plates; and a plurality of support plates for supporting the cooling tubes are arranged in the air housing. The efficient air-air heat exchanger is characterized in that the cooling tubes in the air housing are arranged in the shapes of a plurality of Vs in the cross section direction, each bevel edge of each V shape consists of at least 3-8 rows of cooling tubes which are stacked together, and a space is reserved between the downmost cooling tube and the baseplate of the air housing to form an air duct. According to the utility model, the area of the air flow windward side is enlarged and the flow rate on the windward side is reduced, so that the air side resistance is lowered, and the heat exchange efficiency is improved. The efficient air-air heat exchanger is mainly used in the wind power generation industry.
Description
(1). technical field: the utility model relates to the technical field of heat exchangers in the plant equipment, in particular for a kind of highly effective air-air heat exchanger in the wind-power electricity generation industry.
(2). background technology: in wind-power electricity generation, the little cabin null device compact conformation that requires in space, cabin, because the cabin is positioned at the high-altitude, inconvenient maintenance requires the heat exchanger reliability high.Thereby, mainly adopt air-to-air heat exchanger for the small-power wind power plant.Cooling tube in the air-to-air heat exchanger that uses in the sector at present is to be " one " font stringing; And cooling tube is arranged in the fan housing, and bigger air channel, space is left on top, so heat exchanger volume is big; The hot-air collateral resistance is bigger simultaneously, has influenced the heat exchange efficiency of complete machine.
The (3) summary of the invention: the purpose of the utility model is exactly will overcome existing air-to-air heat exchanger to use the problem that the air collateral resistance is big, influence the heat exchanger heat exchange efficiency, and a kind of highly effective air-air heat exchanger is provided.
The concrete scheme of the utility model is: improve to existing air-to-air heat exchanger, it has fan housing, and left and right sides tube sheet is equipped with at the fan housing two ends; The bottom of fan housing is positioned at the center and is provided with air inlet; The both sides of bottom are provided with left and right sides air outlet, are furnished with some cooling tubes in the fan housing, and the two end supports of all cooling tubes is on the tube sheet of the left and right sides; And in fan housing, being provided with plurality of support supports cooling tube; It is characterized in that: the cooling tube in the fan housing is some " V " font on cross-sectional direction arranges, and each hypotenuse of " V " font is made up of 3-6 row cooling tube stack at least, and the cooling tube of below and the base plate of fan housing have spacing formation lower air duct.
" V " font that cooling tube is arranged described in the utility model can horizontally constitute " W " shape or be arranged above and below formation " X " type.
(4). description of drawings:
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of the utility model.
Among the figure: 1-left tube sheet, 2-cooling tube, 3-gripper shoe, 4-fan housing, 5-right tube sheet, 6-right air outlet, 7-air inlet, 8-left air outlet, 9-lower air duct.
(5). the specific embodiment:
Referring to Fig. 1,2; The utlity model has fan housing 4; Left and right sides tube sheet 1 and 5 are equipped with in fan housing 4 two ends, and the bottom of fan housing 4 is positioned at the center and is provided with air inlet 7, and the both sides of bottom are provided with left and right sides air outlet 6 and 8; Be furnished with some cooling tubes 2 in the fan housing; The two end supports of all cooling tubes 2 and is provided with 3 pairs of cooling tubes 2 of plurality of support and supports on left and right sides tube sheet 1 and 5 in fan housing, it is characterized in that: the cooling tube 2 in the fan housing is two V word one side of something on three " V " fonts and both sides and arranges on cross-sectional direction; Each hypotenuse of " V " font is made up of 2 stacks of 5 row's (can be designed to as required 3-8 row) cooling tubes, and the cooling tube 2 of below has spacing formation lower air duct 9 with the base plate of fan housing 4; The cooling tube 2 mutual placed close together of adjacent two " V " words upper end, and in the junction employing cooling tube 2 is tightly connected; " V " font that cooling tube 2 is arranged in the present embodiment has horizontally constituted " W " shape structure, cooling tube 2 formation " X " the type structure that can also be arranged above and below.
Claims (2)
1. a highly effective air-air heat exchanger has fan housing, and left and right sides tube sheet is equipped with at the fan housing two ends; The bottom of fan housing is positioned at the center and is provided with air inlet; The both sides of bottom are provided with left and right sides air outlet, are furnished with some cooling tubes in the fan housing, and the two end supports of all cooling tubes is on the tube sheet of the left and right sides; And in fan housing, being provided with plurality of support supports cooling tube; It is characterized in that: the cooling tube in the fan housing is some " V " font on cross-sectional direction arranges, and each hypotenuse of " V " font is made up of 3-6 row cooling tube stack at least, and the cooling tube of below and the base plate of fan housing have spacing formation lower air duct.
2. a kind of highly effective air-air heat exchanger according to claim 1 is characterized in that: " V " font that said cooling tube is arranged can horizontally constitute " W " shape or be arranged above and below formation " X " type.
