As shown in Figure 8, compared with prior art, heat-exchange device of the present invention has removed the dividing plate between first internal partition 3 and the top board 23, make second space 33 extend to top board 23 from first internal partition 3, therefore increase the volume in second space 33, thereby can reduce crushing, increased air quantity.And, compared with prior art, suitably improved the position of first internal partition 3, namely increased the distance L 2 between first internal partition 3 and the base plate 22, therefore increase the volume in first space 32, thereby can reduce crushing, increase air quantity.Certainly, if keep air quantity constant, can reduce L2, and the distance L 1 between first internal partition 3 and the top board 23, thereby reduce the volume of thermic devices.
As shown in Figure 8, first internal partition 3 of heat-exchange device and the distance L 1 between the top board 23 are less than the distance L 2 between first internal partition 3 and the base plate 22.Thereby make the pressure balance in first space 32 and second space 33.Can adjust the numerical value of L1: L2 according to the size of intake and air output, thereby realize pressure balance.
As shown in Figure 8, the central axis in the 4th air port 48 is positioned at the below of the horizontal center line on side plate 21 planes.It is close as far as possible that thereby the central axis and the 4th that makes the 4th air port 48 is crossed the center in wind hole 8, even overlap, so that more wind energy is enough directly crossed wind hole 8 to entering the 4th, thereby reduces windage, improves air quantity.Equally, also can make the central axis in first air port 45 be positioned at the below of the horizontal center line on side plate 21 planes.It is close as far as possible that thereby the central axis and first that makes first air port 45 is crossed the center in wind hole 5, even overlap, so that more wind energy is enough directly crossed wind hole 5 to entering first, thereby reduces windage, improves air quantity.
In four heat exchange elements 14, have at least one to be the pore heat exchange elements, namely the aperture is the heat exchange elements below 1.0 millimeters.In this manual, the aperture refers to the width H of the air inlet road 4A shown in Fig. 3 or exhaust line 4B.The heat exchange elements 14 that can be the centre of three heat exchange elements 14 that are arranged in the 4th side plate 214 inboards that power pack 41 is installed as shown in Figure 7 adopts the pore heat exchange elements, also can be that the heat exchange elements 14 at two ends that is arranged in three heat exchange elements 14 of the 4th side plate 214 inboards that power pack 41 is installed adopts the pore heat exchange elements, also can be that other heat exchange elements 14 adopts the pore heat exchange elements.Aforementioned " two ends " refer to, near the position of first side plate 211 or the 3rd side plate 213.Because in heat-exchange device of the present invention, the quantity of heat exchange elements 14 only is half of heat-exchange device of prior art, so, if still all adopt the gross porosity heat exchange elements, that is, the aperture is the heat exchange elements more than 1.5 millimeters, and then heat exchanger effectiveness may not satisfied the demand.
Therefore, can improve the heat exchanger effectiveness in the unit volume, to satisfy actual needs by adopting the pore heat exchange elements.Therefore, heat-exchange device of the present invention can obtain heat exchanger effectiveness same as the prior art under the prerequisite of the quantity that reduces heat exchange elements 14.Be appreciated that according to actual needs both all heat exchange elements 14 all adopted the gross porosity heat exchange elements, also can adopt the pore heat exchange elements by polylith heat exchange elements 14, even all heat exchange elements 14 all adopt the pore heat exchange elements.
Because adopt the pore heat exchange elements, so reduced the cross-sectional area of air feed road and exhaust line, therefore can increase windage.And, because reduced the quantity of heat exchange elements 14, so reduced the quantity of air feed road and exhaust line, therefore also can increase windage.Like this, if still adopt prior art constructions, then air quantity may not satisfied the demand.But, because the present invention has adopted structures such as above-mentioned L shaped guiding space 34, reduced windage, so still can obtain required air quantity.
In the outside of the 4th side plate 214, be provided be used to the power pack 41 of taking in circuit board.During maintenance, the heat exchange elements 14 that will be arranged in the 4th side plate 214 from the heat-exchange device below vertically takes out earlier, at this moment, can stay next bigger space between the 4th side plate 214 and second volute 16, via this space, the maintainer can dismantle power pack 41 and take out easily, thereby overhauls.
