Example 1

The utility model provides a heat exchange piece for a moisture discharging device, as shown in figures 1 to 4, 6 and 7, comprising a heat exchange piece body 20 arranged in a device body 1 for discharging moisture, wherein the heat exchange piece body 20 is provided with a cooling part 21; the cooling portion 21 is provided with a cooling passage 212 for accommodating a cooling medium; wherein the content of the first and second substances,

the cooling channel 212 is provided with a plurality of holes 2121, and the holes 2121 are communicated with the cavity 11 of the device body 1; during the flowing of the cooling medium in the cooling channel 212, part of the cooling medium flows from the holes 2121 to the cavity 11; specifically, part of the cooling medium contacts the hot and humid air in the cavity 11 during flowing in the process of flowing out from the holes 2121, and can also contact part of the hot and humid air in the cavity 11 when flowing to the inner wall of the cavity 11 and being accumulated on the inner wall of the cavity 11, so as to exchange heat with the hot and humid air in the cavity 11;

the moist hot air in the cavity 11 contacts the outer wall of the cooling portion 21 and/or the cooling medium in the cavity 11 for cooling and dehumidification. The damp and hot air generated by the drying drum of the clothes dryer body enters the cavity 11 and contacts the outer wall of the cooling part 21 and/or the cooling medium in the cavity 11, so that the cooling medium absorbs the heat of the damp and hot air, the damp and hot air is cooled and condensed to be dehumidified, and the dehumidified air is discharged out of the clothes dryer body from the air outlet 13 of the device body 1.

In one embodiment, as shown in fig. 2, 3, 6, and 7, the cooling channel 212 is curved to extend the length of the cooling channel 212 and to reasonably control the space occupied by the cooling channel 212 in the cooling portion 21.

In one embodiment, as shown in fig. 2 and 4, the heat exchanger body 20 further includes a plurality of air passages 22 for receiving hot and humid air, and the hot and humid air generated from the drying drum enters the air passages 22 after entering the cavity 11 from the air inlet 12, so as to prolong the time for the hot and humid air to pass through the cavity 11. The air passage 22 is used to guide the flow of hot and humid air, so that the hot and humid air entering the air passage 22 contacts the cooling part 21 for cooling. Further, the air channel 22 is formed by a plurality of fins 23 or a plurality of ejector pins, and the fins 23 have certain thermal conductivity and function to assist heat dissipation of the hot and humid air in the air channel 22. When the cooling portion 21 is located above or beside the air channel 22, the opening below the air channel 22 formed by the fins 23 or the ejector pins is beneficial to removing condensed water formed by condensation of damp and hot air in the air channel 22 in the cooling process, and the condensed water falls onto the inner wall of the casing 10 from the opening below the air channel 22 and is discharged out of the device body 1 from the corresponding water discharge port 15 on the casing 10.

In one embodiment, as shown in fig. 5, the space occupied by the cooling portion 21 in the cavity 11 is one third to one half of the space occupied by the air channel 22 in the cavity 11, so as to increase the height of the air channel 22 and increase the amount of the hot and humid air contained in the air channel 22, and the hot and humid air can be dispersed in the air channel 22, so as to prevent the hot and humid air from being gathered in the air channel 22 due to too small space of the air channel 22, which is not beneficial to the heat transfer of the hot and humid air.

In one embodiment, as shown in fig. 2 and 5, the cooling part 21 is located above the hot humid air. The condensed water formed by the damp and hot air in the cooling process falls under the self gravity and does not contact the outer wall of the cooling part 21, so that the condensed water is prevented from accumulating on the outer wall of the cooling part 21 and influencing the heat absorption of the damp and hot air. Further, the heat exchange member body 20 includes an air passage 22 for receiving hot and humid air, and the cooling part 21 is located above the air passage 22.

In one embodiment, as shown in fig. 2 to 4, a plurality of holes 2121 are disposed on the bottom wall of the cooling channel 212, and the cooling medium falls under its own weight when flowing out of the holes 2121, so as to reduce the adhesion of the cooling medium to the outer wall of the cooling portion 21 during the downward flow process, and prevent the heat exchange between the outer wall of the cooling portion 21 and the hot and humid air.

In one embodiment, as shown in FIG. 4, the holes 2121 correspond to the air passages 22, so that the holes 2121 correspond to the side walls of the air passages 22, thereby preventing the cooling medium from flowing out of the holes 2121. Further, by limiting the aperture size of the holes 2121, the flow rate of the cooling medium flowing out of the holes 2121 is limited, so as to prevent the cooling medium from flowing out of the holes 2121 too fast and falling onto the bottom wall of the cavity 11, thereby reducing the contact time between the cooling medium flowing out of the holes 2121 and the hot and humid air in the cavity 11, reducing the utilization rate of the cooling medium, and causing waste of the cooling medium; in addition, the holes 2121 are controlled to have a diameter so as to prevent the cooling medium from flowing out of the holes 2121 too slowly, so that the cooling effect of cooling by direct contact between the cooling medium and the hot and humid air is not good. It should be understood that the shape of the holes 2121 includes, but is not limited to, circular, square, and bar. By "aperture" is meant a cross-sectional area equivalent to the area of the holes 2121.

In one embodiment, as shown in fig. 2 to 4, the cooling portion 21 includes a cavity, a plurality of partitions 211; the plurality of clapboards 211 are sequentially arranged in the cavity, and two adjacent clapboards 211 are respectively connected to two opposite inner side walls of the cavity in a staggered manner; a number of baffles 211 together with the inner contour of the chamber form cooling channels 212 for the passage of a cooling medium. Replace traditional adoption curved shape pipeline structure as cooling channel's scheme, reduced the space that traditional pipeline structure is crooked and the interval between two adjacent pipeline sections that cause occupies, improved the space size of the cooling channel 212 that same appearance chamber space corresponds promptly, improve the quantity of the coolant that cooling portion 21 held for the heat transfer.

In one embodiment, as shown in fig. 6, the plurality of partition plates 211 are disposed in an inclined manner, so as to increase a contact area between the obliquely disposed partition plates 211 and the cooling medium accommodated in the cooling channel 212, improve heat exchange efficiency between the partition plates 211 and the cooling medium, and accelerate heat absorption of the cooling medium to the hot and humid air. Further, the length of the partition 211 which can be accommodated by the cavity is ensured by defining the included angle between the partition 211 and the inner side wall corresponding to the position of the cavity. The partition 211 is a heat conductive sheet to increase the speed at which the cooling portion 21 absorbs heat of the hot and humid air. In another embodiment, as shown in fig. 1, a plurality of partitions 211 are arranged perpendicular to a profile of one side of the cavity, so as to increase the number of partitions 211 that can be accommodated by the cavity.

In one embodiment, as shown in fig. 2 to 4, 6 and 7, the plurality of partition plates 211 are arranged in parallel, and the cross-sectional profiles of the portions of the channels formed by two adjacent partition plates 211 for accommodating the cooling medium in the same direction are uniform, so that the cooling medium flows smoothly in the channels formed by two adjacent partition plates 211, and the generation of noise due to the turbulence caused by the change of the internal size of the cooling channel is not easy.

Further, the plurality of partitions 211 are arranged at equal intervals in the hot and humid air flowing direction. That is, the cross-sectional profiles of the channels formed between any two adjacent partition plates 211 in the same direction are uniform in size, so that when the cooling medium flows in the cooling channel 212, the flow velocity is uniform or the difference between the flow velocities is not large when the cooling medium passes through a curve and enters the channel formed by the next two adjacent partition plates 211, and the noise caused by unstable flow of the cooling medium is reduced.

Further, the partition 211 is a heat conductive sheet to improve the cooling effect of the cooling portion 21. Specifically, the back on the damp and hot air in cavity 11 transmits heat to cooling portion 21 outer wall, and the heat part on the cooling portion 21 outer wall directly transmits the coolant in cooling channel 212, and the part is passed to earlier and is given baffle 211, and the rethread baffle 211 transmits for coolant for the heat dissipation of the damp and hot air of cooling portion 21 absorption, and then accelerates the absorption of cooling portion 21 outer wall to damp and hot air heat in cavity 11. In addition, the baffle 211 is obliquely arranged in the cavity of the cooling part 21, the length of the baffle 211 is increased to a certain extent, the contact area between the baffle 211 and the cooling medium is increased, the heat exchange efficiency between the cooling medium and the baffle 211 is improved, and the heat absorption of the cooling medium to the damp and hot air is accelerated.

In an embodiment, two adjacent partition boards 211 are respectively connected to two inner walls of the cavity at opposite positions in a staggered manner. Further, the cooling medium inlet end (corresponding to the cooling medium inlet 14 of the housing 10) and the cooling medium outlet of the cooling channel 212 are respectively located at the outer sides of the two partition plates 211 arranged at the outermost side, so as to fully utilize the space of the cavity, so that the space of the cavity is used for accommodating the cooling medium and the partition plates 211, and the amount of the cooling medium accommodated by the cavity is increased.

In one embodiment, the ends of two adjacent partition plates 211 are staggered in a direction perpendicular to the partition plates 211 to form a cooling channel 212 having a curved shape, so as to form a flow path having a curved shape, so that the flow of the cooling medium is stable and the residence time of the cooling medium in the cooling channel 212 is ensured. The cooling medium entering the cavity firstly flows into a first channel connected with the cooling medium inlet end of the cooling channel 212, then flows into a second channel adjacent to the first channel, and then flows into a third channel adjacent to the second channel, and so on, and the plurality of partition plates 211 are reasonably arranged to ensure that the cooling medium flows stably. The adjacent two channels formed by the plurality of partition plates 211 are in a U shape, so that the flowing stability of the cooling medium is further improved.

Further, the vertical distance between two adjacent partitions 211 is equal to the distance between the end of the partition 211 and the inner wall of the casing 10, so as to reduce the influence of the cooling medium flowing to the curve in the cooling passage 212 on the flow speed of the cooling medium, thereby preventing turbulence.

In one embodiment, as shown in fig. 2 and 5, the plane of the partition 211 intersects the plane of the air channel 22. Specifically, the number of the air passages 22 is several, and the plane of the partition 211 intersects the plane of the air passages 22, so that the number of the cooling passages 212 corresponding to each air passage 22 is increased, and the heat exchange efficiency between the cooling medium in the passages of the cooling passages 212 and the hot and humid air in each air passage 22 is improved.

In one embodiment, as shown in fig. 2 to 7, the cooling portion 21 is provided with a cooling medium outlet 213; the cooling medium outlet 213 communicates with the cooling passage 212 and the cavity 11, respectively. The cooling medium introduced into the cooling channel 212 from the cooling medium inlet 14 of the housing 10 flows out from the holes 2121 during the flowing process of the cooling channel 212, and directly contacts with the hot and humid air in the cavity 11 for heat exchange, and finally the cooling medium falls onto the bottom wall of the cavity 11 and is discharged from the water outlet 15 of the housing 10 together with the condensed water generated during the cooling process of the hot and humid air; part of the cooling medium flows into the cavity 11 from the cooling medium outlet 213, is discharged into the cavity 11 from the cooling medium outlet 213 after exchanging heat with the hot and humid air in the cavity 11 contacting the cooling part 21, and is discharged from the drain port 15 of the housing 10 together with the condensed water generated during the cooling of the hot and humid air. The cooling medium outlet 213 is provided on the cooling part 21 but not on the casing 10 to reduce the number of pipes connected to the casing 10 and simplify a pipe arrangement structure when the apparatus body 1 is installed in the dryer body.

Specifically, in one embodiment, the outer wall of the cooling channel 212 contacting the hot and humid air in the cavity 11 is a heat conducting plate structure to ensure the heat exchange effect between the cooling medium in the cooling channel 212 and the hot and humid air. In another embodiment, the heat exchanger body 20 is a heat conducting structure to improve the heat exchange effect with the hot and humid air in the cavity 11.

In an embodiment, as shown in fig. 4 and 5, a stopping portion 2131 is disposed on a back surface of the cooling medium outlet 213 for blocking the cooling medium in the cooling channel 212 from contacting the hot and humid air during flowing out of the cooling medium outlet 213. Since the temperature of the cooling medium after absorbing the heat of the hot humid air is increased, the stopper 2131 is provided to block the contact area between the cooling medium discharged from the cooling medium outlet 213 into the cavity 11 and the hot humid air, so as to prevent the cooling medium after absorbing the heat from being detrimental to the cooling of the hot humid air. In one embodiment, the heat exchange element body 20 includes a plurality of air channels 22 for receiving hot and humid air. The stopper 2131 is arranged to block the cooling medium flowing out from the cooling medium outlet 213 from entering the air passage 22, that is, to prevent the cooling medium absorbing heat of the hot and humid air from flowing into the air passage 22 when the cooling medium is discharged from the cooling passage 212, so as to reduce a contact area between the cooling medium and the hot and humid air, which is increased in temperature due to the absorption of the heat of the hot and humid air, and to prevent the cooling medium absorbing heat from being detrimental to the cooling of the hot and humid air. Further, the stopping portion 2131 is bent to form a surrounding wall structure surrounding the cooling medium flowing out from the cooling medium outlet 213 together with the inner walls of the two sides of the cavity 11, and the surrounding wall structure can be completely or partially closed at the surrounding side to guide the cooling medium to flow to the water outlet 15 and simultaneously separate the air passage 22 from the cooling medium flowing out from the cooling medium outlet 213.

Further, the height of the stopper 2131 is greater than the height of the side wall of the air passage 22 to further ensure that the cooling medium flowing out of the cooling medium outlet 213 does not enter the air passage 22.

Furthermore, the stopping portion 2131 is a heat conducting sheet, the cooling medium discharged from the cooling medium outlet 213 is left along the inner wall of the stopping portion 2131, the hot and humid air in the cavity 11 contacts the outer wall of the stopping portion 2131, and the cooling medium discharged from the cooling medium inlet 14 absorbs part of the heat of the hot and humid air contacting the outer wall of the stopping portion 2131 through the heat transfer function of the stopping portion 2131 which is a heat conducting sheet structure, so that the cooling medium is fully utilized, and the cooling speed of the hot and humid air in the cavity 11 is increased.

In one embodiment, as shown in fig. 3, 6, and 7, a plurality of holes 2121 are distributed on the way to the cooling medium outlet 213. After the cooling medium enters the cooling passage 212 from the cooling medium inlet 14 of the casing 10, the cooling medium flows toward the cooling medium outlet 213, as the cooling medium absorbs more heat from the hot and humid air in the cavity 11, the cooling medium temperature becomes higher and higher until the cooling medium reaches the cooling medium outlet 213, the holes 2121 are distributed on the path leading to the cooling medium outlet 213, i.e. no holes 2121 are provided between the cooling medium outlet 213 and the end of the cooling channel 213, when the cooling medium flows to a position between the cooling medium outlet 213 and the end of the cooling channel 213, the cooling medium is blocked by the contour of the end of the cooling channel 213 and then flows back to the cooling medium outlet 213, so as to prevent the cooling medium from flowing into the cavity 11 to a position between the cooling medium outlet 213 and the end of the cooling passage 213, and the temperature of the cooling medium is high at this time, which is not favorable for cooling the hot and humid air in the cavity 11. Further, the holes 2121 are uniformly distributed on the path leading to the cooling medium outlet 213, so that the cooling medium in the cooling channel 212 is uniformly sprayed to the hot and humid air in the cavity 11 through the holes 2121, thereby improving the heat exchange effect.

In one embodiment, as shown in FIG. 7, the interior profile of the plurality of holes 2121 tapers in size in the direction of the flow of the cooling medium within the cooling passage 212. The cooling medium in the cooling channel 212 gradually increases in temperature during the flowing process, and the temperature is highest when the cooling medium flows to the cooling medium outlet 213, so that the cooling medium with high temperature in the cooling channel 212 flows into the cavity 11 from the holes 2121 less by limiting the size of the inner contour of the holes 2121, and the influence of the temperature difference of the cooling medium flowing into the cavity 11 from the holes 2121 on the cooling effect of the hot and humid air in the cavity 11 is reduced.

Further, as shown in fig. 2 and 5, the height of the partition 211 is smaller than the height of the peripheral side contour of the receiving cavity, so as to facilitate the processing of the cooling portion 21 and reduce the requirement for the processing accuracy of the partition 211, so as to prevent the height of the partition 211 being higher than the height of the peripheral side contour of the receiving cavity during the processing from affecting that the outer contour of the opening of the cooling portion 21 abuts against the inner wall of the housing 10, and further the cooling channel 212 cannot be closed, and when the cooling medium in the cooling channel 212 is more or flows more rapidly, the cooling medium in the cooling channel 212 is likely to leak from the gap between the outer contour of the opening of the cooling portion 21 and the inner wall of the housing 10.

In an embodiment, as shown in fig. 2 and 5, the cooling medium outlet 213 provided in the cooling portion 21 is disposed on the bottom wall of the receiving cavity. The cooling medium can directly fall to the inner bottom wall of the cavity 11 after flowing out from the cooling medium outlet 213 under the self gravity, so as to reduce the probability of the contact between the cooling medium and the peripheral side contour of the cavity 11, and avoid the increase of the humidity in the cavity 11 caused by the accumulation of the cooling medium on the peripheral side contour surface of the cavity 11, which is not beneficial to the dehumidification of the damp and hot air.

In one embodiment, as shown in fig. 2 and 3, a distance is provided between the cooling medium outlet 213 and the end of the cooling channel 212.
