As shown in fig. 1, the heat exchanger 10 is disposed in the air supply duct, and the heat exchanger 10 defines a closed heat exchange channel, and the heat exchange channel is used for accommodating a heat exchange medium. That is, the heat exchanger 10 is internally provided with a heat exchange channel for accommodating a heat exchange medium, and the heat exchange medium flows in the heat exchange channel, so that when external air enters the air supply duct, the heat exchange medium in the heat exchanger 10 can be utilized to exchange heat with the air entering the air supply duct, so that the temperature of the air in the air supply duct is increased, the air with higher temperature is convenient to process the clothes in the clothes processing cavity, the processing quality of the clothes processing device 1000 and the efficiency of processing the clothes are improved, and the user experience is improved.

Meanwhile, the heat exchange channel in the heat exchanger 10 is formed to define a closed heat exchange channel, and the closed heat exchange channel can be convenient to form a vacuum environment, so that the heat exchanger 10 can also realize the flow of a heat exchange medium in the heat exchange channel on the premise of not arranging a liquid suction core.

That is, the heat exchanger 10 of the present application does not need to provide a wick, thereby reducing the heat transfer resistance of the heat exchanger 10 in the heat transfer process, thereby improving the heat exchange efficiency of the heat exchanger 10, and omitting the wick can also reduce the production cost of the heat exchanger 10, and make the structure of the heat exchanger 10 simple.

Furthermore, the overall size of the heat exchanger 10, i.e. the space occupied by the heat exchanger 10, can be reduced without the need for a wick.

As shown in fig. 1, 2 and 3, the heat exchanger 10 includes a first pipe section 141, a second pipe section 142 and a connecting pipe section 143, both ends of the connecting pipe section 143 are respectively communicated with one end of the first pipe section 141 and one end of the second pipe section 142, the connecting pipe section 143 forms a curved pipe section, and at least one side surface of the connecting pipe section 143 is a plane.

It is also understood herein that the first tube segment 141, the second tube segment 142 and the connecting tube segment 143 cooperate such that the heat exchanger 10 itself defines a closed heat exchange channel.

As can be seen from the above structure, in the laundry treating apparatus 1000 according to the embodiment of the present utility model, the occupied space of the connecting pipe section 143 can be reduced by making at least one side surface of the connecting pipe section 143 planar, so as to reduce the occupied space of the heat exchanger 10, that is, the volume of the heat exchanger 10, thereby reducing the difficulty in arrangement of the heat exchanger 10 and improving the space utilization of the laundry treating apparatus 1000 when the heat exchanger 10 is disposed in the laundry treating apparatus 1000.

In addition, the structure of the connection pipe section 143, that is, the structure of the heat exchanger 10 is simplified by making at least one side surface of the connection pipe section 143 planar, so that the structure of the heat exchanger 10 is simplified, and thus the structure of the fixing member is also simplified when the fixing member for fixing the heat exchanger 10 is manufactured, and thus the structure of the laundry treating apparatus 1000 is simplified when the heat exchanger 10 is disposed in the laundry treating apparatus 1000.

It can be appreciated that, compared with the prior art, the present application provides the heat exchanger 10 with the surface of at least one side of the connection pipe 143 being planar, and the heat exchanger 10 being disposed in the laundry treating device 1000, so that the laundry treating device 1000 has the advantages of simple structure, convenient assembly, etc.

In some examples, the surfaces of the opposite sides of the connecting pipe section 143 in the up-down direction are formed to be flat, where the connecting pipe section 143 may be formed to be substantially flat, and the opposite sides of the connecting pipe section 143 in the up-down direction may not have a bending phenomenon.

In some examples, as shown in fig. 2 and 3, the same side surfaces of the first tube segment 141, the second tube segment 142, and the connecting tube segment 143 are coplanar. While the surface of the connection pipe section 143 can be formed to be planar, the difficulty in manufacturing the first pipe section 141, the second pipe section 142, and the connection pipe section 143, that is, the difficulty in manufacturing the heat exchanger 10 can be reduced, thereby improving the heat exchange efficiency of the heat exchanger 10.

In addition, by arranging the same side surfaces of the first pipe section 141, the second pipe section 142 and the connecting pipe section 143 to be coplanar, the volume of the heat exchanger 10 can be further reduced, that is, the occupied space of the heat exchanger 10 can be reduced, and the heat exchanger 10 can be conveniently fixed and installed.

In some examples, as shown in fig. 2 and 3, the first tube segment 141, the second tube segment 142, and the connecting tube segment 143 each form a flat tube. The flat tube can ensure that the surface of the connecting tube section 143 can be formed into a plane, and simultaneously the overall structure of the heat exchanger 10 is compact, so that the volume of the heat exchanger 10 is reduced, that is, the occupied space of the heat exchanger 10 is reduced, and thus, when the heat exchanger 10 is arranged in the clothes treating apparatus 1000, the difficulty in arranging the heat exchanger 10 can be reduced, and meanwhile, the space utilization rate of the clothes treating apparatus 1000 can be improved.

Alternatively, as shown in fig. 4 and 5, a cavity 144 is formed in the flat tube, and a plurality of spaced baffles 145 are provided in the cavity 144 to form a plurality of micro-channels 1441 in the cavity 144. The cooperation of many micro-channels 1441 can make the heat transfer medium distribute evenly in flat pipe, makes the heat transfer medium distribute evenly in heat exchanger 10 promptly to realize promoting the heat transfer effect of heat exchanger 10, thereby make the heat exchanger 10 of this application have advantages such as heat transfer is even, the heat transfer is effectual. When setting up heat exchanger 10 in the air supply wind channel of clothing processing apparatus 1000 like this, heat exchanger 10 can be effectively to getting into in the air supply wind channel and exchange heat, and the air after the heat transfer reentrant clothing processing intracavity to realize carrying out drying treatment to the clothing in the clothing processing chamber, and then realize promoting the processingquality of clothing processing apparatus 1000, promote user's use experience.

In addition, by providing a plurality of baffles 145 within the cavity 144 of the heat exchanger 10, the plurality of baffles 145 may also be utilized to support the side walls of the heat exchanger 10 to stabilize the overall structure of the heat exchanger 10.

Alternatively, as shown in connection with fig. 4 and 5, a plurality of micro-channels 1441 in the flat tube are arranged at intervals along the width direction of the flat tube. The width direction is herein understood to be the front-rear direction shown in fig. 1, that is, the plurality of micro channels 1441 in the heat exchanger 10 are arranged at intervals in the front-rear direction of the heat exchanger 10, so that when the heat exchange medium flows along the micro channels 1441, the heat exchange medium can cover the cavity 144 in the whole heat exchanger 10, and smooth flow of the heat exchange medium in the micro channels 1441 is ensured, so as to improve uniformity of heat exchange of the heat exchanger 10.

In summary, the heat exchanger 10 of the present application has no wick, simple structure, lower cost, higher reliability, and higher heat transfer capability than conventional heat pipes, without the heat transfer limit specific to conventional heat pipes.

Optionally, a plurality of micro-channels 1441 in the flat tube are arranged at intervals along the width direction of the flat tube and extend along the length direction of the flat tube, so as to ensure that the heat exchange medium can flow smoothly in the micro-channels 1441.

It should be further noted that, because the heat exchange efficiency of the heat exchange assembly is very high in the laundry treatment apparatus 1000, the conventional tubular pulsating heat pipe is difficult to be applied to a large-sized device such as the laundry treatment apparatus 1000 because the pipe diameter is only about 2mm, and the tubular pulsating heat pipe about 2mm is not beneficial to improving the heat exchange efficiency of the laundry treatment apparatus 1000 because the heat exchange area of the heat exchange assembly has a large influence on the heat exchange efficiency. Therefore, by arranging the micro-channels 1441 in the flat tube of the heat exchanger 10, each micro-channel 1441 can form an independent pulsating heat pipe to improve the heat exchange efficiency of the heat exchanger 10, and thus, when the heat exchanger 10 is arranged in the clothes treatment device 1000, the requirement of high-performance heat exchange of the clothes treatment device 1000 can be effectively met.

In some examples, as shown in fig. 2 and 3, the heat exchanger 10 includes a plurality of first heat exchange tubes 14 and a plurality of second heat exchange tubes 15, the plurality of first heat exchange tubes 14 being arranged at intervals in a first direction and the plurality of first heat exchange tubes 14 being in end-to-end communication in the first direction by the plurality of second heat exchange tubes 15 such that the heat exchanger 10 itself defines a closed heat exchange channel. The first direction is herein understood to be the up-down direction shown in fig. 2, that is, the plurality of first heat exchange tubes 14 are arranged at intervals in the up-down direction, and the plurality of first heat exchange tubes 14 are sequentially connected end-to-end through the plurality of second heat exchange tubes 15 in the up-down direction, so that the heat exchange medium contained in the heat exchange channel can flow between the plurality of first heat exchange tubes 14.

That is, the heat exchanger 10 comprising the plurality of first heat exchange tubes 14 and the plurality of second heat exchange tubes 15 is arranged in the clothes treating apparatus 1000, the heat exchange efficiency of the heat exchanger 10 is improved, meanwhile, the production cost of the heat exchanger 10 can be reduced, the occupied space of the heat exchanger 10 is further reduced, the production cost of the clothes treating apparatus 1000 can be reduced when the heat exchanger 10 is applied to the clothes treating apparatus 1000, the structure of the clothes treating apparatus 1000 is simple, meanwhile, the temperature of air in an air supply duct can be effectively improved, and clothes in a clothes treating cavity can be conveniently treated by utilizing air with higher temperature, so that the treatment quality of the clothes treating apparatus 1000 and the efficiency of clothes treatment are improved, and the user experience is improved.

It should be noted that, because the heat exchanger 10 is disposed in the air supply duct and the heat exchanger 10 defines a closed heat exchange channel for accommodating the heat exchange medium, when air flows in the air supply duct, the air can contact the heat exchanger 10 and exchange heat with the heat exchange medium in the heat exchanger 10, so as to raise the temperature of the air in the air supply duct, and then the air with higher temperature enters the clothes treatment cavity and acts on the clothes to be treated, so as to dry the clothes, that is, achieve the purpose of treating the clothes, thereby the clothes treatment device 1000 of the present application has the capability of treating the clothes.

To sum up, the heat exchanger 10 is configured to include a flat tube and the heat exchanger 10 is configured to be formed by combining a plurality of first heat exchange tubes 14 and a plurality of second heat exchange tubes 15, so as to effectively improve the heat exchange efficiency of the heat exchanger 10, simplify the structure of the heat exchanger 10, and reduce the production cost of the heat exchanger 10.

Alternatively, the plurality of first heat exchange tubes 14 and the plurality of second heat exchange tubes 15 are each formed in a separate structure, and the plurality of second heat exchange tubes 15 are connected to the plurality of first heat exchange tubes 14 during the production of the heat exchanger 10 to form the heat exchanger 10.

The connection may be welding, bonding, or the like. That is, the plurality of second heat exchange tubes 15 are welded or bonded to the plurality of first heat exchange tubes 14 to form the integral heat exchanger 10.

Of course, in other examples, the heat exchanger 10 may be formed as an integral piece, that is, the first heat exchange tube 14 and the second heat exchange tube 15 are formed as an integral piece, so that connection between the first heat exchange tube 14 and the second heat exchange tube 15 can be omitted in the process of processing the heat exchanger 10, so as to reduce manufacturing difficulty of the heat exchanger 10, improve manufacturing efficiency of the heat exchanger 10, and meanwhile, improve connection strength of the first heat exchange tube 14 and the second heat exchange tube 15, avoid leakage of heat exchange medium in a heat exchange channel at a connection position of the first heat exchange tube 14 and the second heat exchange tube 15, and improve use safety of the heat exchanger 10 while guaranteeing heat exchange efficiency of the heat exchanger 10.

Alternatively, the closed heat exchange channels may be connected end to end, so that the heat exchanger 10 forms a closed ring structure (as shown in fig. 2 and 3); alternatively, the heat exchange channels may be spaced end-to-end such that the heat exchanger 10 forms an open serpentine configuration (not shown in this example). The present application is not particularly limited.

In some examples, the heat exchanger 10 is formed as a pulsating heat pipe. The pulsating heat pipe can work without external energy supply, compared with the traditional heat pipe, the heat exchanger 10 has the advantages of simple structure, lower cost, smaller volume, higher reliability, no special heat transfer limit of the traditional heat pipe, higher heat transfer capacity, higher heat flux density in the pulsating heat pipe, no drying out, random bending, contribution to miniaturization design, further simple structure, low production cost, small volume, high reliability, higher heat transfer capacity and the like.

In addition, after the pulsating heat pipe is selected as the heat exchanger 10, the operation performance of the heat exchanger 10 is not basically affected by the action of gravity, so that the heat exchanger 10 can operate under the environments of gravity field inversion, gravity field change and the like.

That is, the heat exchanger 10 of the present application has a simple structure, low production cost, small volume, high reliability, high heat exchange efficiency, convenient cleaning, and can operate in multiple environments such as gravity field inversion, gravity field change, etc.

Alternatively, the heat exchange medium may be cooling water or a refrigerant. Cooling water or refrigerant is filled in the heat exchange channels to ensure that the heat exchanger 10 is able to exchange heat effectively with air flowing therethrough.

In a specific example, the heat exchange medium is a refrigerant, so as to improve the heat exchange performance of the heat exchanger 10.

Optionally, each of the first heat exchange tube 14 and the second heat exchange tube 15 is a flat tube, and a plurality of spaced separators 145 are disposed in the cavities 144 of the first heat exchange tube 14 and the second heat exchange tube 15, so that a plurality of micro-channels 1441 can be formed in the first heat exchange tube 14 and the second heat exchange tube 15 respectively, and the micro-channels 1441 cooperate to uniformly distribute the heat exchange medium in the first heat exchange tube 14 and the second heat exchange tube 15, so as to improve the heat exchange effect of the first heat exchange tube 14 and the second heat exchange tube 15, that is, to improve the heat exchange effect of the heat exchanger 10, so that the heat exchanger 10 of the application has the advantages of uniform heat exchange, good heat exchange effect and the like.

Optionally, after the plurality of first heat exchange tubes 14 are sequentially connected end to end through the plurality of second heat exchange tubes 15, the separator 145 in the first heat exchange tube 14 is opposite to the separator 145 in the second heat exchange tube 15, so that the micro-channel 1441 in the first heat exchange tube 14 is opposite to the micro-channel 1441 in the second heat exchange tube 15, and the heat exchange medium can conveniently circulate in the first heat exchange tube 14 and the second heat exchange tube 15.

Alternatively, as shown in fig. 3, each first heat exchange tube 14 includes a first tube segment 141, a second tube segment 142, and a connection tube segment 143, the other end of the first tube segment 141 of each first heat exchange tube 14 communicates with one of the second heat exchange tubes 15, and the other end of the second tube segment 142 communicates with the other of the second heat exchange tubes 15. The heat exchange medium can flow circularly among the plurality of first heat exchange pipes 14, namely, the heat exchange medium in the heat exchanger 10 can flow into the other first heat exchange pipe 14 from one first heat exchange pipe 14, and the heat exchange medium can flow through the plurality of first heat exchange pipes 14 in sequence in the heat exchanger 10, so that the heat exchange area of the heat exchange medium is increased, the heat exchange of the heat exchange medium in the heat exchanger 10 is more sufficient, and the heat exchange efficiency of the heat exchanger 10 is improved.

Alternatively, as shown in fig. 1, 2 and 8, the heat exchanger 10 has an evaporation portion 11, a condensation portion 12 and a connection portion 13, the connection portion 13 being communicated between the evaporation portion 11 and the condensation portion 12, the evaporation portion 11 including a plurality of first pipe sections 141, the condensation portion 12 including a plurality of second pipe sections 142, the connection portion 13 including a plurality of connection pipe sections 143. By providing the connection portion 13 formed of the plurality of connection pipe sections 143, it is ensured that the plurality of first pipe sections 141 of the evaporation portion 11 and the plurality of second pipe sections 142 of the condensation portion 12 can be communicated in one-to-one correspondence, thereby ensuring that the heat exchange medium in the evaporation portion 11 and the heat exchange medium in the condensation portion 12 can flow each other, thereby enabling the heat exchanger 10 to have the ability of exchanging heat, so as to effectively ensure the processing quality of the laundry treating apparatus 1000.

The connection portion 13 mainly communicates the evaporation portion 11 and the condensation portion 12. It will also be appreciated that the connection 13 only serves as a transitional connection and does not take part in the heat exchange process.

In addition, since the evaporation portion 11 includes the plurality of first tube segments 141 and the condensation portion 12 includes the plurality of second tube segments 142, it can be understood that the evaporation portion 11 and the condensation portion 12 are each composed of a plurality of flat tubes, and each flat tube is formed with a plurality of micro-channels, due to the micro-channel size effect, the plurality of micro-channels can make the heat exchange medium form a plunger with a gas-liquid interval in the heat exchanger 10, the heat exchange medium forms bubbles after the flat tubes of the evaporation portion 11 are heated and evaporated, rapidly expands and boosts, and pushes the heat exchange medium to flow into the flat tubes of the condensation portion 12 with low temperature, in the flat tubes of the condensation portion 12 with low temperature, the bubbles shrink and break due to cooling, the pressure is reduced, and due to the pressure imbalance between the two ends and the pressure imbalance between the adjacent micro-channels, the heat exchange medium oscillates between the evaporation portion 11 and the condensation portion 12, thereby realizing heat transfer, and in the whole process, no external mechanical work and electric work are consumed, the self-oscillation under the driving of the pressure of the condensation portion 12 is completely, and the purpose of using the heat exchanger 10 to perform heat exchange is achieved.

In some examples, as shown in fig. 1, the evaporator 11 is facing the intake 220 of the supply air duct. That is, an air inlet 220 is formed at one side of the air supply duct, and during the specific operation of the laundry treatment apparatus 1000, the air entering the air supply duct through the air inlet 220 may be pre-cooled by the evaporation portion 11 of the heat exchanger 10, the condensation portion 12 of the heat exchanger 10 re-heats the sub-cooled air, and the heat is automatically transferred from the evaporation portion 11 to the condensation portion 12 by using the temperature difference of the system, thereby achieving the purpose of heat exchange.

Alternatively, as shown in fig. 1, the laundry treating apparatus 1000 further includes an evaporator 20, the evaporator 20 and the heat exchanger 10 being disposed at an opposite interval in a second direction, the second direction and the first direction being perpendicular to each other. Wherein the second direction is understood herein to be the front-to-back direction as shown in fig. 6. That is, the evaporator 20 and the heat exchanger 10 are disposed at intervals in the front-rear direction of the laundry treating apparatus 1000, so that when the external air flows along the front-rear direction of the laundry treating apparatus 1000, the heat exchange between the evaporator 20 and the heat exchanger 10 can be realized without changing the flowing direction of the external air, and the heat exchange efficiency can be further improved by using the cooperation of the evaporator 20 and the heat exchanger 10 to exchange heat with the air entering the air supply duct while simplifying the difficulty of the passage arrangement of the external air.

In a specific example, as shown in fig. 1, the heat exchanger 10 and the evaporator 20 are combined to form the evaporator assembly 100, that is, the evaporator assembly 100 formed by combining the heat exchanger 10 and the evaporator 20 is arranged in the clothes treating apparatus 1000, and the heat exchanger 10 and the evaporator 20 are matched to maximally improve the heat exchange performance of the evaporator assembly 100, and meanwhile, the performance of the evaporator assembly 100 can be improved by fully utilizing the advantages of the heat exchanger 10, so that the evaporator assembly 100 has the advantages of compact structure, small occupied space, good heat exchange effect, high heat exchange efficiency and low cleaning difficulty, and the working performance of the clothes treating apparatus 1000 is improved.

It is further emphasized that, because the heat exchanger 10 of the present application has good heat exchange performance, compared with the conventional tube-fin heat exchanger, the volume of the evaporator 20 of the present application can be greatly reduced on the premise of requiring the same heat exchange performance, so as to reduce the layout space required by the evaporator 20 and reduce the installation difficulty of the evaporator 20.

Alternatively, the evaporator 20 is a microchannel evaporator. The microchannel evaporator has the advantages of compact structure, light weight, high heat exchange efficiency, corrosion resistance and the like, so that the evaporator 20 is set into the microchannel evaporator, so that the heat exchange efficiency of the evaporator 20 is effectively improved, the volume of the evaporator 20 is reduced, the service life of the evaporator 20 is prolonged, namely, the heat exchange efficiency of the evaporator assembly 100 is improved, the volume of the evaporator assembly 100 is reduced, and the service life of the evaporator assembly 100 is effectively prolonged.

Alternatively, the length directions of the first and second pipe sections 141 and 142 extend along the third direction, respectively, and are spaced apart from each other in the second direction, and the third direction, the second direction, and the first direction are perpendicular to each other. The third direction is understood to be the left-right direction shown in fig. 6, that is, the first pipe section 141 and the second pipe section 142 are arranged at intervals in the front-rear direction under the action of the connecting pipe section 143, and the length directions of the first pipe section 141 and the second pipe section 142 extend along the left-right direction of the heat exchanger 10, so that the evaporating portion 11 and the condensing portion 12 can be further ensured to be arranged at intervals relatively in the front-rear direction of the heat exchanger 10, and thus when the external air flows along the front-rear direction of the heat exchanger 10, the flow direction of the external air can exchange heat with the evaporating portion 11 and the condensing portion 12 respectively without changing, and the heat exchange efficiency can be improved and the heat exchange difficulty can be reduced while the channel arrangement difficulty of the external air is simplified.

Alternatively, the evaporator 20 is provided at a side of the evaporation portion 11 remote from the condensation portion 12 (not shown in this example drawing). That is, the evaporator 20 is disposed at one side of the heat exchanger 10 and close to the air inlet 220, so that when the evaporator assembly 100 is used to exchange heat with the external air, the external air passes through the evaporator 20 to exchange heat with the heat exchanger 10, and then the heat exchange performance of the evaporator assembly 100 is improved.

Alternatively, as shown in conjunction with fig. 1 and 6, the evaporator 20 is provided between the evaporation portion 11 and the condensation portion 12. That is, the evaporator 20 is not limited to be disposed on the side of the evaporation portion 11 away from the condensation portion 12, but may be disposed between the evaporation portion 11 and the condensation portion 12, so that the heat exchange performance of the evaporator assembly 100 can be improved while the evaporator 20 is protected and the service life of the evaporator 20 is prolonged by the cooperation of the evaporation portion 11 and the condensation portion 12.

The method comprises the following steps: through the above arrangement, during the actual operation of the evaporator assembly 100, the external air firstly exchanges heat through the evaporation portion 11 of the heat exchanger 10 and transfers the absorbed heat to the condensation portion 12, so as to improve the condensation efficiency of the evaporator 20, that is, the heat exchange performance of the evaporator assembly 100.

Alternatively, the evaporator 20 and the heat exchanger 10 are provided independently of each other. It is understood herein that the evaporator 20 and the heat exchanger 10 are not connected to each other, and form a system independent of each other, so as to avoid circulating the heat exchange medium in the heat exchanger 10 between the heat exchanger 10 and the evaporator 20. That is, the heat exchange medium of the heat exchanger 10 is limited to move in a sealed channel after being filled into the heat exchanger 10, so that when the heat exchanger 10 and the evaporator 20 are installed in the clothes treating apparatus 1000, the heat exchanger 10 is used as a complete heat exchange element to realize a heat exchange process, and the heat exchange medium does not need to be connected with other elements to realize heat exchange, thereby reducing the layout difficulty of the heat exchanger 10 and improving the practicability of the heat exchanger 10.

Alternatively, as shown in fig. 6 and 8, the height direction of the evaporator 20 extends in a first direction extending in an up-down direction, and the evaporation portion 11 extends obliquely in the first direction from bottom to top toward a direction away from the evaporator 20. Wherein, the height direction of the evaporator 20 is set to extend in the up-down direction so that the evaporator 20 has a certain area, facilitating the heat exchange of the external air by the evaporator 20.

Further, the evaporation portion 11 is provided to extend obliquely in the first direction from bottom to top toward a direction away from the evaporator 20. In this way, in the heat exchange process of the heat exchanger 10, the condensed water generated on the evaporation part 11 can automatically flow into the water accumulation tray arranged below the heat exchanger 10 under the action of gravity, so that on one hand, the drainage capacity of the heat exchanger 10 is enhanced, and further, the heat exchange performance of the evaporator assembly 100 is improved; on the other hand, condensed water on the evaporation portion 11 is prevented from being blown onto the evaporator 20 of the evaporator assembly 100 to ensure heat exchange performance of the evaporator 20.

It should be emphasized that part of the burrs on the evaporation portion 11 can be washed away during the flowing process of the condensed water, so as to achieve the purpose of cleaning the heat exchanger 10, further enhance the chip removing capability of the heat exchanger 10, and reduce the cleaning difficulty of the heat exchanger 10.

That is, the inclined evaporation portion 11 enhances the drainage and chip removal capability of the heat exchanger 10, improves the heat exchange performance of the evaporator assembly 100, and reduces the difficulty of cleaning the heat exchanger 10.

To sum up, the evaporator assembly 100 of the present application not only improves the heat exchange performance of the heat exchanger 10, but also arranges the evaporation portion 11 of the heat exchanger 10 to extend obliquely along the first direction from bottom to top toward a direction away from the evaporator 20, so as to improve the heat exchange performance of the evaporator assembly 100 to the maximum.

It should be noted that, by providing the evaporation portion 11 of the heat exchanger 10 to extend obliquely from bottom to top in the first direction toward the direction away from the evaporator 20, a portion of the filth may be carried away, and in some specific examples, in order to further improve the cleanliness of the evaporator assembly 100, the filth may be cleaned by a brush.

It should be further noted that, because the evaporation portion 11 is disposed opposite to the air inlet 220, the above arrangement can also ensure that the condensation water generated by the heat exchanger 10 is discharged at the front end of the heat exchanger 10 during the heat exchange process, so as to avoid the condensation water from being blown onto the evaporator 20, thereby ensuring the heat exchange performance of the evaporator 20.

Alternatively, the condensation portion 12 extends obliquely in the first direction from the bottom to the top toward the direction approaching the evaporator 20. That is, not only the evaporation portion 11 but also the condensation portion 12 are provided to extend obliquely.

The method comprises the following steps: the evaporation portion 11 of the heat exchanger 10 is arranged to extend obliquely along the first direction from bottom to top towards a direction far away from the evaporator 20, the condensation portion 12 of the heat exchanger 10 is arranged to extend obliquely along the first direction from bottom to top towards a direction close to the evaporator 20, so that the inclination directions of the evaporation portion 11 and the condensation portion 12 positioned at two sides of the evaporator 20 are consistent, the whole heat exchanger 10 is arranged to incline relative to the evaporator 20 in the process of arranging the heat exchanger 10, the arrangement difficulty of the heat exchanger 10 is reduced, and the assembly difficulty of the evaporator assembly 100 is reduced while the drainage capacity of the evaporator assembly 100 is improved.

Alternatively, the heat exchanger 10 is adapted to be mounted on a horizontal mounting surface, the first direction being perpendicular to the horizontal mounting surface, the mounting angle of the heat exchanger 10 being acute with respect to the horizontal mounting surface. Here, the horizontal installation surface is understood to be a plane parallel to the third direction and the second direction, and when the installation angle of the heat exchanger 10 with respect to the plane is an acute angle, it is possible to achieve oblique installation of the heat exchanger 10 on the horizontal installation surface, thereby making the heat exchanger 10 be disposed obliquely.

Alternatively, the mounting angle of the evaporator 20 is a right angle with respect to the horizontal mounting surface. That is, the evaporator 20 is vertically installed on the horizontal installation surface, so that when the evaporator 20 is disposed between the evaporation portion 11 and the condensation portion 12, it is possible to dispose the evaporation portion 11 of the heat exchanger 10 to extend obliquely in the first direction from the bottom to the top toward the direction away from the evaporator 20, so as to utilize the drainage capacity of the heat exchanger 10.

Alternatively, as shown in fig. 8, the distance between the upper end of the evaporation part 11 and the evaporator 20 in the second direction is larger than the distance between the lower end of the evaporation part 11 and the evaporator 20 in the second direction, and the distance between the upper end of the condensation part 12 and the evaporator 20 in the second direction is smaller than the distance between the lower end of the condensation part 12 and the evaporator 20 in the second direction. Through the arrangement, the evaporation part 11 can extend obliquely along the first direction from bottom to top towards the direction far away from the evaporator 20, and the condensation part 12 extends obliquely along the first direction from bottom to top towards the direction close to the evaporator 20, so that the heat exchanger 10 can be arranged obliquely relative to the vertically extending evaporator 20, and the drainage and chip removal capacities of the heat exchanger 10 are improved.

In summary, it will be understood that the overall structure of the heat exchanger 10 is inclined with respect to the evaporator 20, rather than just the upper surface of the heat exchanger 10 being inclined with respect to the evaporator 20, such that the existing heat exchanger 10 can be directly used without separately producing the heat exchanger 10, and in the process of assembling the evaporator assembly 100, only the installation angle of the heat exchanger 10 needs to be correspondingly adjusted when the heat exchanger 10 is installed, so as to reduce the manufacturing difficulty of the heat exchanger 10.

Alternatively, as shown in conjunction with fig. 6 and 7, the evaporation portion 11 includes a plurality of first fins 111, and the plurality of first fins 111 are provided on the first tube segments 141 of the plurality of first heat exchange tubes 14.

Alternatively, as shown in fig. 6 and 7, a plurality of first fins 111 are provided at intervals along the length direction of the first tube segment 141, and the side of the first fins 111 remote from the evaporator 20 exceeds the side of the first tube segment 141 remote from the evaporator 20. That is, when the evaporator 20 is disposed between the evaporation portion 11 and the condensation portion 12, a side, away from the evaporator 20, of the first fin 111 on the evaporation portion 11 extends in a direction away from the evaporator 20, so that a side, away from the evaporator 20, of the first fin 111 can exceed the first tube segment 141, and thus, the first fins 111 disposed on the plurality of first tube segments 141 can be communicated in a first direction at a side, away from the evaporator 20, at this time, condensed water flowing downward due to gravity can flow along the first direction extending direction of the first fin 111, thereby facilitating drainage of the condensed water, and at the same time, a vertical penetrating channel for cleaning the burrs is provided, thereby facilitating cleaning of the burrs, and further reducing cleaning difficulty of the heat exchanger 10.

That is, the present application, by providing the plurality of first fins 111 on the first pipe section 141, can improve the heat exchange performance of the first pipe section 141, and simultaneously facilitate the drainage of condensed water and reduce the cleaning difficulty of the heat exchanger 10.

In addition, by arranging the plurality of first fins 111 and the plurality of heat exchange fins 21 to be staggered in the third direction, it is also understood that the projections of the plurality of first fins 111 and the plurality of heat exchange fins 21 on the second plane are staggered, and the second plane is parallel to the third direction and the first direction, so that when air flows through the evaporator assembly 100, turbulence in the air flow can be increased, and the heat exchange capacity of the evaporator assembly 100 can be improved.

Alternatively, as shown in fig. 9, the plurality of second fins 121 are staggered with the plurality of heat exchange fins 21 in the third direction. Here, the arrangement positions of the plurality of second fins 121 and the plurality of heat exchange fins 21 in the third direction are staggered, where the staggered arrangement is also understood as that the projections of the plurality of second fins 121 and the plurality of heat exchange fins 21 on the second plane are staggered, so that when the air flows through the evaporator assembly 100, the disturbance of the air flow can be further increased, and the heat exchange capability of the evaporator assembly 100 is improved.

In some examples, as shown in connection with fig. 3 and 9, both sides of the second fin 121 in the width direction are flush with both sides of the second tube segment 142 in the width direction, i.e., the second fin 121 is divided into a plurality of parts by the plurality of second tube segments 142, and during the actual installation of the second fin 121, the plurality of parts of the second fin 121 may be inserted between the plurality of second tube segments 142 and welded with the plurality of second tube segments 142 to achieve the connection of the second fin 121 with the plurality of second tube segments 142.

That is, the upper surfaces of the first heat exchange tube 14 and the second heat exchange tube 15 are inclined with respect to a plane parallel to the third direction and the second direction, so that when the heat exchanger 10 is installed in place, the condensed water on the upper surfaces of the first heat exchange tube 14 and the second heat exchange tube 15 automatically flows into the water collecting tray disposed below the heat exchanger 10 under the action of gravity.

Alternatively, the thickness direction of the first heat exchange tube 14 is disposed obliquely with respect to the second plane and parallel to the third plane, the second plane is parallel to the third direction and the first direction, the third plane is parallel to the second direction and the first direction, and the width direction of the first heat exchange tube 14 is disposed obliquely with respect to the first plane and parallel to the third plane.
