The structure of the ventilation unit that the present invention relates to is identical with the structure of illustrated ventilation unit among Fig. 1, so here repeat no more.
Fig. 3 is a ventilation unit heat conductive exchanger oblique view of the present invention.
As shown in Figure 3, heat conductive exchanger for ventilator 40 of the present invention includes the gripper shoe 41 of closed on both sides face, stacked and be formed with the suction chamber outer air and discharge a plurality of unit heat exchange department 45 of the one-way flow passage 47,49 of room air between gripper shoe, the reinforcement 43 of the V-shaped groove that is suitable for four jiaos of installation unit heat exchange departments is set in order to support the said units heat exchange department.
Here, in the time of reinforcement 43 support unit heat exchange departments 45, be fixed on the shell that constitutes ventilation unit and and its partition wall on, support heat conductive exchanger 40 thus.
Unit heat exchange department 45 includes the heat exchanger plate 45a of two sides and form the fold plate 45b of the one-way flow passage of air between above-mentioned heat exchanger plate.Between the above-mentioned fold plate 45b certain spacing is arranged, form air flow passage 47,49 thus.Above-mentioned heat exchanger plate 45a is the both sides that the center is arranged on it with any fold plate 45b, so carry out heat exchange through the room air of above-mentioned fold plate 45b or the outdoor air or the room air of outdoor air and process adjacent pleats plate by the heat transmission.
Stacked for the mutual square crossing of air flow passage that makes fold plate 45b formation, in the adjacent air flow passage of unit heat exchange department 45, an inlet channel 47 that becomes the outdoor air that is communicated with air induction conduit, another becomes the exhaust passage 49 of the room air that is communicated with exhaust manifolds.As, in the accompanying drawing up and down longitudinally air flow passage be the inlet channel 47 of room air, about horizontal air flow passage be the exhaust passage 49 of room air.
Here, inlet channel 47 and exhaust passage 49 comprise a plurality of friction grooves that promising raising forms a plurality of embossing portions of air flow passage respectively through the convection effects of air and the friction campaign of air is enlivened.
Describe the structure of above-mentioned inlet channel and exhaust passage below in detail.
Fig. 4 a is a heat conductive exchanger part exploded perspective view according to an embodiment of the invention, and diagram forms the unit heat exchange department of inlet channel.Fig. 4 b is the I-I line profile of Fig. 4 a.
Shown in Fig. 4 a, unit heat exchange department 45 is made of fold plate 45b that forms the outdoor air inlet channel and the heat exchanger plate 45a that the room air that is arranged on the both sides up and down of above-mentioned fold plate and makes outdoor air the exhaust passage (omitting among the figure) adjacent with process carries out the square shape of heat exchange.
Above-mentioned fold plate 45b comprises by having certain depth for the spacing that keeps inlet channel and being parallel to the 45c of embossing portion that protrudes back separated by a distance on the outdoor air flow direction and producing the friction groove 45d that convection effects is arranged between the embossing portion and constitute for promoting the air friction.
Therefore, the above-mentioned embossing 45c of portion forms the flow channel of outdoor air, plays up and down the compartment function of mobile air outward in order to make the heat exchanger plate 45a of outdoor air by both sides up and down and room air carry out heat exchange simultaneously.
Above-mentioned friction groove 45d has small curvature on the inlet channel surface of outdoor air process, and playing increases the momental function of outdoor air.In order to realize above-mentioned functions, friction groove 45d can form variform.That is, the opposite direction that friction groove 45d protrudes to the 45c of embossing portion in order to have small camber forms, and perhaps also can form to the direction that the 45c of embossing portion protrudes.In addition, friction groove 45d is formed between two 45c of embossing portion, perhaps also can be formed on the surface of the 45c of embossing portion.Illustrated friction groove 45d is that the opposite direction of protruding to the 45c of embossing portion on the fold plate 45b that does not form the 45c of embossing portion forms in the accompanying drawing.
Though do not illustrate, the direction that above-mentioned friction groove protrudes to the 45c of embossing portion forms and also belongs to technical characterictic scope of the present invention.
In this state, above-mentioned friction groove 45d equally is parallel to the direction of outdoor air flow with the 45c of embossing portion.
In addition, the degree of depth of friction groove 45d becomes important factor for the amount of exercise of air and the pressure loss.That is, above-mentioned friction groove 45d is dark more, and the friction area between friction groove and the air is big more.Therefore, friction groove 45d increases the amount of exercise of air, but dwindles the flow path cross sectional area of above-mentioned inlet channel, loses at the front and back of inlet channel two side's initiation pressures.Especially, if friction groove 45d forms to the direction that the 45c of embossing portion protrudes, can ignore the pressure loss that above-mentioned friction groove causes.
Therefore, the present invention is shown in Fig. 4 b, and the degree of depth h2 of friction groove is the 1/10[1/10th of the degree of depth h1 of embossing portion] about.That is, it is about 10% of the 45c of embossing portion degree of depth h1 that friction groove 45d is provided with the degree of depth, and to the direction of the 45c of embossing portion protrusion or to forming in the other direction.Above-mentioned data are optimum values of considering that the friction amount of exercise of air and the pressure loss draw through test repeatedly.
In addition, because the inlet channel of heat conductive exchanger is identical structure with the exhaust passage, aforesaid unit heat exchange department 45 structures only are not limited in the inlet channel, are suitable for too on the exhaust passage.
The effect of the heat conductive exchanger of Gou Chenging is as follows like this.
According to the running of blowing fan and ventilating fan, outdoor air and room air enter 49 li of the inlet channel 47 of heat conductive exchanger and exhaust passages through the path of appointment respectively.At this moment, air collision reaction in the friction groove 45d on fold plate 45b surface of process inlet channel and exhaust passage.That is, air is after friction in the friction groove 45d, and it flows and becomes warm current and increase amount of exercise, the result to the convective heat transfer of the heat exchanger plate 45a of adjacency become active.
Therefore, outdoor air and room air carry out heat transmission glibly between above-mentioned heat exchanger plate 45a that is oppositely arranged up and down, so the heat exchanger effectiveness that is undertaken by above-mentioned heat conductive exchanger rises.
Fig. 5 is a heat conductive exchanger part exploded perspective view according to another embodiment of the present invention, illustrates the unit heat exchange department fold plate that forms inlet channel and exhaust passage.
The heat exchange department of unit according to another embodiment of the present invention as shown in Figure 5, fold plate 55b comprise that having certain depth and the 55c of embossing portion that protrudes in the direction that is parallel to outdoor air flow back separated by a distance and the friction groove 55d that is arranged between the embossing portion in order to promote the air friction to produce the effect of convection current for the spacing that keeps inlet channel constitutes.
The shape of above-mentioned embossing 55c of portion and friction groove 55d is identical with the friction groove with the embossing portion of above-mentioned Fig. 4 with function, the difference certain angle of the relative circulation of air direction inclination of groove 55d that only is to rub.
The reason that above-mentioned friction groove 55d forms certain inclined angle alpha is to allow the friction that the air here produces of flowing through increase convection effects.That is, the length direction from unit heat exchange department leaked-in air along the 55c of embossing portion flows, because friction groove 55d flows so friction groove 55 influences to a certain extent along the air of embossing portion to the 55c of embossing portion inclination certain angle α.At this moment, friction groove 55d is not the factor that the containment air flows, and applies elastic force and increases momental factor but become air flowed.Therefore, the air through above-mentioned friction groove 55d transmits heat (omitting among the figure) to the heat exchanger plate of adjacency better because of the amount of exercise increase.
At this moment, flow and the heat exchanger effectiveness consideration in conjunction with air, the inclined angle alpha of the relative circulation of air direction of above-mentioned friction groove should have suitable scope.Inclination angle among the present invention is 30 °.
More than be with preferred embodiment explanation the present invention.But those of ordinary skill in the art can propose different variant embodiment in basic fundamental thought range of the present invention.Here, basic fundamental scope of the present invention is narrated in patent claims, and is also included within the claim of the present invention with change shape in its same range as.
