The cooling medium introduced into the cooling channel 212 from the cooling medium inlet 14 of the housing 10 exchanges heat with the hot and humid air in the cavity 11 contacting the cooling portion 21, so that the cooling medium in the cooling channel 212 absorbs the heat of the hot and humid air in the cavity 11, is discharged into the cavity 11 from the cooling medium outlet 213, and is discharged from the water discharge port 15 of the housing 10 together with the condensed water generated during the cooling process 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, the casing 10 is provided with an air inlet 12 and an air outlet 13, the air inlet 12 is communicated with the clothes drying cylinder, and the air outlet 13 is communicated with the external environment of the clothes drying machine body. After a drying program of the clothes dryer body is started, the heater of the clothes dryer body heats air entering the clothes drying cylinder, the heated air enables moisture contained in clothes contained in the clothes drying cylinder to be heated and evaporated to form air flow containing water molecules, the air flow containing the water molecules is mixed into hot air in the clothes drying cylinder under the guidance of a fan of the clothes dryer body to form damp and hot air with higher temperature and humidity, the damp and hot air generated by the clothes drying cylinder enters the cavity 11 through the air inlet 12 and contacts the cooling part 21 of the heat exchange part body 20 positioned in the cavity 11 to be cooled, the damp and hot air forms condensed water in the cooling process to be dehumidified, the air after being cooled and dehumidified is discharged into the external environment of the clothes dryer body, the influence on the temperature and the humidity of the environment where the clothes dryer body is positioned is reduced, and environmental pollution is avoided; and the damp and hot air in the clothes drying cylinder is discharged in time, so that the drying procedure of the clothes dryer body is accelerated. Further, the temperature and humidity of the air exhausted into the external environment of the dryer body after being processed by the device body 1 can be controlled by limiting the heat absorption performance of the cooling portion 21, for example, the temperature of the air exhausted by the dryer body can be controlled to be slightly lower than the room temperature, the humidity is a humidity standard for comfortable life, and when the temperature is in a hot season, the temperature of the environment around the dryer body can be properly adjusted, so as to improve the user experience. The cooling medium inlet 14 of the casing 10 communicates with the cooling passage 212 to introduce the cooling medium.

In one embodiment, as shown in FIG. 2, the cooling medium outlet 213 corresponds to the position of the drain 15 of the housing 10. The drain 15 of casing 10 is located the diapire of casing 10, and the comdenstion water that damp and hot air formed in the cooling process in the air passage 22 drops to the inside diapire of casing 10 on, discharges from drain 15, is favorable to the discharge of comdenstion water to avoid the comdenstion water to be kept over in cavity 11, and influence the inside humidity of cavity 11, and then influenced the cooling effect of cooling portion 21. After the cooling medium absorbing the heat of the hot and humid air is discharged from the cooling medium outlet 213, the cooling medium can reach the water discharge port 15 to be discharged as soon as possible under the self-gravity, so that the cooling medium cannot be discharged in time in the cavity 11 and is accumulated in the cavity 11, the humidity of the cavity 11 is not affected, and the dehumidification of the hot and humid air is not facilitated.

In one embodiment, as shown in fig. 2, 3, and 5, the cooling medium outlet 213 is close to the air inlet 12 of the housing 10. The damp and hot air generated by the clothes drying cylinder enters the cavity 11 from the air inlet 12, at this time, the humidity of the damp and hot air is high, that is, the humidity and the temperature of the air in the cavity 11 near the air inlet 12 are the highest, and the cooling medium outlet 213 is arranged near the air inlet 12, so that the temperature and the humidity of the damp and hot air at the air inlet 12 are not greatly influenced by the cooling medium discharged from the cooling medium outlet 213. Furthermore, the cooling medium outlet 213 corresponds to the position of the water outlet 15, when the cooling medium and the condensed water formed in the cooling process of the hot and humid air flow toward the water outlet 15, the humidity in a certain space around the water outlet 15 is affected to a certain extent, the temperature and humidity of the hot and humid air at the air inlet 12 are not greatly affected by the temperature and humidity in a certain space around the water outlet 15, and even if the temperature and humidity of the hot and humid air at the air inlet 12 are affected to increase, the hot and humid air at the air inlet 12 exchanges heat with the cooling medium to reduce the temperature and dehumidify in the process of flowing toward the air outlet 13 of the housing 10, so as to ensure that the temperature and humidity of the air discharged from the air outlet 13 meet the limited requirement.

If a small part of the hot and humid air contacts the cooling medium, the part of the hot and humid air has a small amount of air, and thus can exchange heat with the cooling medium in the cooling part 21 to remove moisture when passing through the air passage 22.

In one embodiment, the apparatus body 1 is provided with a partition for dividing the cavity 11 into two regions; the cooling portion 21 and the hot and humid air are respectively located in the two separating members, so that the cooling portion 21 and the hot and humid air entering the cavity 11 are respectively located in two relatively independent spaces, and the hot and humid air is prevented from forming condensed water in the cooling process to cause the outer wall of the cooling portion 21 to contact with more moisture, which is not beneficial for the cooling portion 21 to absorb heat of the hot and humid air. Further, in an embodiment, the heat exchanger body 20 includes an air channel 22 for receiving hot and humid air, and the cooling portion 21 and the air channel 22 are respectively located at two sides of the partition, so that the cooling portion 21 and the air channel 22 are respectively located in two relatively independent spaces. Specifically, the condensed water formed by cooling and condensing the damp-heat air in the air channel 22 may increase the humidity of the space where the air channel 22 is located to a certain extent, and separate the cooling portion 21 from the air channel 22, and the increase of the humidity of the air channel 22 may not affect the humidity of the environment where the cooling portion 21 is located, so as to prevent the increase of the humidity of the environment where the cooling portion 21 is located from causing the outer wall of the cooling portion 21 to contact with more water molecules, and the cooling portion 21 may absorb the heat of the water molecules contacted by the outer wall thereof, thereby affecting the cooling effect of the cooling portion 21.

Specifically, the cooling portion 21 abuts against the contour of the cavity 11 toward the circumferential side of the first wall 214 of the air passage 22 to form a partition, and occupies the space inside the cavity 11 without providing an additional partition. Further, two sides of the first wall 214 respectively contact the cooling medium in the cooling channel 212 and the hot and humid air in the air channel 22, and the first wall 214 is a heat conducting fin to increase the speed of transferring the heat of the hot and humid air to the cooling medium in the cooling channel 212, and increase the heat exchange efficiency. Further, the first wall 214 is provided with a plurality of mounting holes 2141, and a plurality of mounting portions 111 are disposed in the cavity 11 and correspond to the plurality of mounting holes 2141, respectively, so as to fix the heat exchange element body 20 in the cavity 11 by a fastening member.

In one embodiment, as shown in FIG. 2, a distance is provided between the cooling medium outlet 213 and the end of the cooling channel 212. When the cooling medium flows to the cooling medium outlet 213 in the cooling channel 212, part of the cooling medium flows from the cooling medium outlet 213 to the water outlet 15 after flowing into the cavity 11, and part of the cooling medium continues to flow to the end of the cooling channel 212 in order to achieve a certain flow splitting effect, so as to avoid that the cooling medium flowing to the end of the cooling channel 212 cannot be discharged from the cooling medium outlet 213 in time to form turbulence and cause noise when the cooling medium outlet 213 is arranged at the end of the cooling channel 212.

In one embodiment, as shown in fig. 2, the cooling portion 21 includes a cavity, a plurality of partitions 211; the 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; the plurality of partition plates 211 and the inner contour of the cavity jointly form the cooling channel 212 for the cooling medium to pass through, the traditional scheme that a bent pipeline structure is adopted as the cooling channel is replaced, the space occupied by the space between two adjacent pipeline sections due to the bending of the traditional pipeline structure is reduced, namely, the space size of the cooling channel 212 corresponding to the same cavity space is increased, the amount of the cooling medium contained in the cooling part 21 is increased, and the heat exchange is accelerated.

In one embodiment, the plurality of partition plates 211 are disposed 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 consistent, 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. 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.

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 baffles 211 is equal to the distance between the end of the baffle 211 and the inner wall of the cavity, so as to reduce the influence of the cooling medium flowing to the curve in the cooling channel 212 on the velocity of the cooling medium, thereby avoiding turbulence.

In one embodiment, the cooling portion 21 is provided with an opening; opening into the curved cooling channel 212.
