Abstract
The utility model relates to a two direction ventilation heat exchanger for a ventilation machine. In order to provide a heat exchanger with high heat exchanger effectiveness and small air flow resistance for a ventilation machine, the utility model is composed of a plurality of heat exchanger plates and a plurality of spacing plates. The spacing plate presents a corrugation shape; the spacing plates are arranged between the two heat exchanger plates at intervals, and the corrugation directions of the spacing plates positioned on both sides of a same heat exchanger plate are caused to be vertical.
Description
The utility model belongs to heat exchanger, the bidirectional ventilated heat exchanger of particularly a kind of ventilator.
The heat exchanger of commonly using is generally heat convection and heat exchanger wall heat is conducted the heat exchanging process that heat exchange combines.This heat exchanger, its hot and cold air-flow is separated by heat exchanger wall, and along with flowing of hot and cold air, heat is finished from High Temperature Gas by heat exchanger wall and is spread transmittance process to low-temperature airflow.But air-flow is when flowing through heat exchanger wall, form along the heat exchanger wall and laminar boundary layer or the turbulent boundary layer vertical at its near surface with hot conduction orientation, and laminar boundary layer is hindered heat exchange and limits, and promptly this heat exchanger is that the heat convection by means of the turbulent boundary layer of conduction of the heat by heat exchanger wall and wall both sides thereof carries out heat exchange.For this reason, Chinese patent ZL96306227.1 discloses the interactive heat exchanger of ventilator as shown in Figure 1, this heat exchanger is when carrying out heat exchange, and outside air-flow is turned the heat exchange area about 25% being arranged approximately is the dead band, makes heat exchange area fail to make full use of; And because in heat exchanging process, air-flow need change 90 ° of angles, thereby the air-flow local resistance is increased.
The purpose of this utility model provides a kind of heat exchanger effectiveness height, the bidirectional ventilated heat exchanger of the little ventilator of gas-flow resistance.
The utility model is made up of plural piece heat exchanger plate and plural interblock dividing plate, and space bar is corrugated.Space bar is disposed between two heat exchanger plates, and makes the ripple direction of the space bar that is positioned at same heat exchanger plate both sides perpendicular.
Wherein:
The ripple of space bar is curved ripple.
The ripple of space bar is the indention ripple.
The ripple of space bar is for being the pectination ripple, and it constitutes with parallel interval plural spacer bar disposed thereon.
Be on the corrugated space bar direction vertical and be fluctuating curved surface shape with the ripple direction.Space bar is disposed between two heat exchanger plates, and makes the ripple direction of the space bar that is positioned at same heat exchanger plate both sides perpendicular.During use, be connected with the gas outlet perpendicular to the ripple direction of ripple direction identical distance plate respectively, make air-flow pass through the heat exchanger plate both sides, stopped to increase because of air-flow turns to the air-flow local resistance because of causing with streamlined flow with two centrifugal blowers.Plural number piece heat exchanger plate has increased heat exchange area, improve heat conducting heat exchanger effectiveness, be the turbulivity that the corrugated space bar makes the air-flow layering and changes air-flow with the roughness that increases gas channel, to improve the heat exchanger effectiveness of heat convection, not only gas-flow resistance is little, and the heat exchanger effectiveness height, thereby reach the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 2, the utility model is made up of plural piece heat exchanger plate 1 and plural interblock dividing plate 2.Heat exchanger plate 1 is for being that the dull and stereotyped aluminium foil of 0.05mm is made by thickness.Space bar 2 is also for being that the dull and stereotyped aluminium foil of 0.05mm is made by thickness, and is corrugated.As shown in Figure 3, the ripple 21 of space bar 2 is curved ripple.Also can be as shown in Figure 4, the ripple 22 of space bar 2 is the indention ripple.Also can be as shown in Figure 5, the ripple 23 of space bar 2 is for being the pectination ripple, and it constitutes with parallel interval plural spacer bar 231 disposed thereon.As shown in Figure 6, also can make and be corrugated space bar 2 and on the direction vertical, be fluctuating curved surface shape 24 with ripple 21 (22,23) direction.Space bar 2 is disposed between two heat exchanger plates 1, so that keep certain (spacing of 2mm～5mm) and between adjacent two heat exchanger plates 1 with (changing the turbulivity of ripple cycle in the 2mm～10mm), improve the effect of heat exchange with the change air-flow at certain ripple periodic regime.And order to be positioned at the direction of ripple 21 (22,23) of space bar 2 of same heat exchanger plate 1 both sides perpendicular.
The utility model is when carrying out heat exchange, as shown in Figure 7, be connected with give vent to anger side 2A, the 2B perpendicular to ripple 21 (22,23) direction of ripple 21 (22,23) direction identical distance plate 2 respectively with two centrifugal blowers 3,4, and the outlet wind speed of centrifugal blower 3,4 is guaranteed more than 3m/sec, so that enter reynolds number Re 〉=2000 of air-flow in the utility model, to realize convective heat exchange.
As shown in Figure 8, the utility model is placed in the ventilator 5 with two air inlet 51A, 51B and two gas outlet 52A, 52B, and make air-supply centrifugal blower 3 and air draft centrifugal blower 4 place the side of giving vent to anger perpendicular to ripple 21 (22,23) direction of ripple 21 (22,23) direction identical distance plate 2 respectively, and order air-supply centrifugal blower 3 is positioned at its nearly air-supply and gives vent to anger outside the side, and is connected with the gas outlet 52A of ventilator 5.Air draft centrifugal blower 4 is positioned at its nearly air draft gives vent to anger outside the side, and is connected with the gas outlet 52B of ventilator 5.Start air-supply centrifugal blower 3 and air draft centrifugal blower 4, outdoor new wind A entered through the air inlet 51A of ventilator 5, flow through the utility model, carry out heat exchange after, send into indoor by the gas outlet 52A of ventilator 5.Indoor dirty wind B enters through the air inlet 51B of ventilator 5, flows through the utility model, carry out heat exchange after, discharge outdoor by the gas outlet 52B of ventilator 5.Just finish bidirectional ventilated heat exchange.
