In a specific embodiment, the air conditioning device may be any device that can perform air conditioning by ventilation or air circulation, and the air conditioning may be, for example, the adjustment of the temperature of air, and may also be, for example, the adjustment of components in air. For example, the air conditioning device may be an air purification device capable of reducing suspended particles in air; for example, the air conditioning device may also be an air conditioner, which may adjust the temperature of the air; alternatively, the air conditioning device may be a bathroom heater. For convenience of explanation, the following description will exemplify the structure of the air conditioning apparatus by taking the air conditioning apparatus as an example and taking the air conditioning apparatus as an example for adjusting the temperature of air.

In some embodiments, as shown in fig. 1, the air conditioning device 1 includes: a housing 10, a fan assembly 20 and an electronic control box 30. The housing 10 is formed with a containing cavity 11, and the containing cavity 11 is opened with an air outlet 12. The fan assembly 20 is disposed in the accommodating cavity 11 and connected to the air outlet 12 to drive the air in the housing 10 to flow to the air outlet 12. Referring to fig. 2, the air conditioner 1 is taken as an example of an air conditioner, and the process of flowing air into and out of the accommodating chamber 11 will be described in an exemplary manner. The housing 10 is further provided with an air inlet 13, and a temperature adjusting system for adjusting the temperature of air is further arranged in the accommodating cavity 11. The fan assembly 20 sucks air into the accommodating cavity 11 through the air inlet 13, the temperature adjusting system can change the temperature of the air entering the accommodating cavity 11, and the fan assembly 20 can blow out the air with the changed temperature from the air outlet 12. The temperature adjusting system may be any device capable of changing the temperature of the air, and for example, the temperature adjusting system may absorb heat of the air through evaporation of the cooling medium, thereby reducing the temperature of the air; the temperature regulating system can also be a heating element which heats the air in a heat conduction mode. Alternatively, the fan assembly 20 can also suck air from the air outlet and blow the air out from the air inlet 13. In the case where the air conditioner 1 is used in a toilet, the blower assembly 20 can blow outdoor air into the toilet after temperature change, and can also guide air with odor or water vapor in the toilet out of the toilet.

The electronic control box 30 is connected to the housing 10 for controlling the operation state of the air conditioner 1.

The electronic control box 30 has a heat sink 31, and the heat sink 31 is at least partially located in an air duct adjacent to the air outlet 12, and the air flow in the air duct flows through the heat sink 31. The air duct may be any space communicating with the air outlet 12, for example, the air duct may be at least part of the accommodating cavity 11, and the air duct may also be an external space of the housing 10 near the air outlet 12. The heat sink of the related air conditioner is disposed on the outer surface of the housing of the air conditioner, and the cooling of the electronic control box is achieved by heat exchange between the external air and the heat sink, but in the case where the external air does not flow, the heat sink can only exchange heat with the air near the heat sink, and the heat dissipation capability is weak. In the air conditioning device 1 provided by the utility model, in the operation process of the air conditioning device 1, the fan assembly 20 sucks air into the accommodating cavity 11 and forms airflow in the air duct communicated with the accommodating cavity 11, at least part of the radiating element 31 is arranged in the accommodating cavity 11, so that the radiating element 31 can exchange heat with the airflow in the accommodating cavity 11 on the premise of not additionally arranging a cooling fan, the heat of the radiating element 31 is quickly taken away by the flowing air, the cooling effect of the radiating element 31 on the electronic control box 30 is improved, the possibility of damage of the electronic control box 30 due to overheating is further reduced, the possibility of thermal fatigue of the electronic control box 30 is further reduced, and the service life of the electronic control box 30 is prolonged.

The heat dissipation member 31 may be any structure capable of dissipating heat through thermal convection, for example, the heat dissipation member 31 is a heat dissipation fin made of a material with high thermal conductivity, and the heat dissipation fin exchanges heat with air flowing through the air duct, so that heat generated in the electronic control box 30 can be quickly taken away by the air, thereby cooling the electronic control box 30; for example, the heat dissipation member 31 may also be fins arranged at intervals, the contact area between the fins and the air is increased by an uneven structure, and heat exchange is performed between the fins and the air flowing through the air duct, so that heat generated in the electronic control box 30 can be quickly taken away by the air, and thus the electronic control box 30 is cooled. Optionally, the heat sink 31 is fixedly connected to the housing 10. Optionally, the housing 10 is further provided with a mounting hole through which the heat sink 31 enters the air duct.

An embodiment of the present invention provides an air conditioning apparatus, including: the fan assembly comprises a shell with an accommodating cavity, a fan assembly arranged in the accommodating cavity, and an electric control box connected with the shell. The air outlet is arranged in the accommodating cavity, and the fan assembly is connected with the air outlet so as to drive the gas in the shell to flow to the air outlet. Wherein, automatically controlled box is provided with the radiating piece, and at least part of radiating piece is located the wind channel with the air outlet intercommunication to make the radiating piece can hold the mobile air contact of intracavity with the inflow, make the heat that the radiating piece was taken away fast to the air that flows, thereby improve the radiating effect of radiating piece to automatically controlled box, and then reduce the overheated possibility of damaging of automatically controlled box, or reduce the possibility that automatically controlled box produced thermal fatigue, prolonged the life of automatically controlled box.

In some embodiments, as shown in fig. 3, the housing 10 is further provided with a fitting opening 14 communicating with the accommodating chamber 11, and at least a portion of the heat sink 31 is inserted into the fitting opening 14, so that at least a portion of the heat sink 31 can be located in the accommodating chamber 11 and can be detachably connected to the housing 10 to facilitate replacement and cleaning of the heat sink 31. Alternatively, the size of the inner edge of the fitting opening 14 is the same as the size of the inner edge of the heat sink 31, so that the gap between the heat sink 31 and the inner edge of the fitting opening 14 is reduced, thereby reducing noise generated by collision of the heat sink 31 with the inner edge of the fitting opening 14 during operation of the air-conditioning apparatus 1.

In some embodiments, as shown in fig. 3, the electronic control box 30 further has an electronic control body 32, which is used for implementing the control function of the air conditioner 1, and at the same time, a large amount of heat is generated during the operation of the electronic control body 32. The heat sink 31 is at least partially located outside the electronic control body 32 and connected to the electronic control body 32, so as to cool the electronic control body 32 by heat exchange between the heat sink 31 and the external airflow of the electronic control body 32. The electric control body 32 is disposed outside the housing 10, that is, a part of the electric control body 32 is disposed outside the accommodating chamber 11, and another part of the electric control body 32 is disposed inside the accommodating chamber 11 and on the surface of the electric control body 32 inside the accommodating chamber 11, and the heat dissipation member 31 is disposed, so that the electric control body 32 is conveniently maintained and replaced while the electric control body 32 is cooled by the air flowing in the accommodating chamber 11.

Optionally, as shown in fig. 4, the electronic control body 32 includes an electronic control housing 321, a control cavity 322 is formed inside the electronic control housing 321, and the control cavity 322 is used for accommodating an electronic component 323 for implementing a control function. The heat sink 31 is disposed on the outer surface of the electronic control housing 321, and the heat sink 31 exchanges heat with the flowing air by contacting the flowing air in the accommodating chamber 11, thereby reducing the temperature of the portion of the electronic control housing 321 where the heat sink 31 is disposed. At this time, a temperature difference is formed in the electronic control housing 321, and the temperature of the position close to the heat sink 31 is lower than the temperature of the position far from the heat sink 31, so that heat exchange is formed in the electronic control housing 321, and the heat of the portion far from the heat sink 31 is conducted to the heat sink 31, so that the heat sink 31 can integrally cool the space in the electronic control housing 321. Wherein the heat exchange in the electrically controlled housing 321 can be realized in any form. For example, as shown in fig. 4, the electric control housing 321 is filled with a heat-conducting gas, which may be air, and heat exchange between different positions in the electric control housing 321 is realized through heat convection and heat radiation of the air. For example, as shown in fig. 5, a cooling pipe 324 is provided in the control chamber 322, a part of the cooling pipe 324 is attached to a surface of the electronic component 323 for implementing a control function, and another part of the cooling pipe 324 is in contact with the heat sink 31. The cooling line 324 is filled with a cooling liquid that circulates in the cooling line 324 between a position near the electronic component 323 and a position near the heat sink 31, so that heat exchange between different positions in the control chamber 322 is achieved by the flow of the cooling liquid.

In some embodiments, the heat sink 31 is disposed inside the electronic control body 32, and the heat sink 31 concentrates heat in the electronic control body 32 on the surface of the electronic control body 32 by exchanging heat with air in the electronic control body 32, and cools the electronic control body 32 by exchanging heat between the electronic control body 32 and air outside the electronic control body 32. For convenience of description, the structure of the heat sink 31 will be described below by way of example, with at least part of the heat sink 31 being disposed outside the electronic control body 32.

In some embodiments, as shown in fig. 6, the housing 10 has a surrounding portion 141 surrounding the mounting opening 14, and the surrounding portion 141 opens a vent hole 142 communicating with the accommodating chamber 11. Specifically, ventilation hole 142 is the through-hole, can communicate and hold chamber 11 and the exterior space who holds chamber 11, at the in-process of air conditioning equipment 1 operation, the air that holds the chamber outside can be held in chamber 11 by ventilation hole 142 entering, simultaneously, set up ventilation hole 142 on the fender portion 141 that encloses with the assembly opening 14 is adjacent, can make ventilation hole 142 be located near inserting the radiating piece 31 of assembly opening 14, thereby can make more air current flow through radiating piece 31, the radiating effect of radiating piece 31 to automatically controlled box 30 has further been improved, the life of automatically controlled box 30 has been prolonged.

Alternatively, as shown in fig. 7, the housing 10 is provided with both the air inlet 13 and the vent hole 142, and in a state where the air conditioner 1 needs to suck air from the outside, the air conditioner 1 can respectively suck air from the air inlet 13 and the vent hole 142, that is, through the vent hole 142 and the air inlet 13, so that the heat dissipation effect of the heat dissipation member 31 on the electronic control box 30 is improved, the air inlet amount of the air conditioner 1 is increased, and the air outlet amount of the air conditioner 1 per unit time is increased. Optionally, as shown in fig. 6, the housing 10 is provided with the ventilation hole 142, and an air inlet is not provided, that is, the ventilation hole 142 simultaneously achieves the function of the air inlet, so that the structure of the housing 10 is more compact, and meanwhile, the flow rate of air entering the accommodating cavity 11 from the ventilation hole 142 can be increased by only sucking air through the ventilation hole 142, so that the air flows through the heat sink 31 at a faster speed, and the heat dissipation effect of the heat sink 31 on the electronic control box 30 is further improved.

In some embodiments, as shown in fig. 6, the fence 141 is provided around the inner edge of the mounting opening 14 so that the fence 141 can be provided around the heat sink 31 after the heat sink 31 is inserted into the mounting opening 14. Meanwhile, the plurality of ventilation holes 142 are arranged at intervals along the direction surrounding the heat dissipation member 31, so that air can vertically flow into the heat dissipation member 31 from different directions, and the heat dissipation effect of the heat dissipation member 31 on the electronic control box 30 is further improved.

In some embodiments, the vent holes 142 are multiple, and the multiple vent holes 142 are spaced apart from each other and distributed in a rectangular array. That is, the vent holes 142 are arranged at intervals in one direction to form a row of vent holes, and then the row of vent holes is arranged at intervals in a direction perpendicular to the one direction, so that a vent hole array is formed in a rectangular area, and thus more air can be blown to the heat dissipation member 31 by the vent holes 142, and the heat dissipation effect of the heat dissipation member 31 on the electrical control box 30 is further improved.

In some embodiments, as shown in fig. 8, the heat sink 31 has a plurality of fins 311, and the fins 311 are spaced apart and parallel to each other, and a heat dissipation air duct 312 is formed between the fins 311. By arranging the heat sink 31 as a plurality of fins 311 arranged at intervals, the surface area of the heat sink 31 is increased, and the contact area between the heat sink 31 and the air is increased, so that the heat sink 31 can exchange heat with the air at a higher speed, and the heat dissipation effect of the heat sink 31 on the electronic control box 30 is further improved. Optionally, as shown in fig. 9, the heat sink 311 includes a plurality of sub-heat sinks 313, each sub-heat sink 313 is disposed at an interval in the extending direction perpendicular to the heat sink 311, so that an auxiliary heat dissipation air duct 314 perpendicular to the heat dissipation air duct 312 is formed between the sub-heat sinks 313, and each auxiliary heat dissipation air duct 314 is communicated with the heat dissipation air duct 312, so that while the surface area of the heat sink 31 is further increased, air can flow through the heat dissipation air duct 312 and the auxiliary heat dissipation air duct 314 from different directions, and the heat dissipation effect of the heat sink 31 on the electronic control box 30 is further increased.

In some embodiments, as shown in fig. 10, at least a portion of the vent holes 142 extend in a direction parallel to the surface of the heat sink 311. Specifically, the extending direction of at least some of the ventilation holes 142 is parallel to the extending direction of the cooling fins 311, so that the air flowing in from the ventilation holes 142 can flow through the surface of the cooling member 31 along the cooling air duct 312, and the air can be sufficiently contacted with the surface of each cooling fin 311. The arrangement of the ventilation holes 142 and the flow direction of air at the heat sink 31 after entering the ventilation holes 142 will be exemplified below by taking as an example that each of the cooling fins 311 extends in the vertical direction. As shown in fig. 11, the ventilation holes 142 are provided at portions above and below the heat dissipation member 31, and the extension direction of the ventilation holes 142 is a numerical direction, and air flows from the ventilation holes 142 above and below the heat dissipation member 31 to the heat dissipation member 31, respectively, and flows into the heat dissipation air duct 312 between the respective heat dissipation fins 311 shown in fig. 8. After the air flows into the heat dissipation air duct 312, the air flows horizontally along the heat dissipation air duct 312 and flows out of the heat dissipation air duct 312 under the suction of the fan assembly 20 shown in fig. 1, so as to take away the heat of the heat dissipation member 31.

Alternatively, as shown in fig. 12, the extending direction of a part of the ventilation holes 142 is parallel to the surface of the heat sink 311, and the extending direction of another part of the ventilation holes 142 is perpendicular to the surface of the heat sink 311, and in the case where the heat sink 311 includes a plurality of sub-fins 313 arranged at intervals, the air flowing in from the ventilation holes 142 can be respectively perpendicular to the heat sink 31 from the direction parallel to the surface of the heat sink 311 and the direction perpendicular to the surface of the heat sink 311. The arrangement of the ventilation holes 142 and the flow direction of air at the heat sink 31 after entering the ventilation holes 142 are exemplified by the following arrangement in which the cooling fins 311 extend in the vertical direction and the respective sub-cooling fins are provided at intervals in the vertical direction as an example. As shown in fig. 13, the ventilation holes 142 are provided around the heat sink 31, the portions of the shielding part 141 above and below the heat sink 31 are provided with first ventilation holes 143, and the extending direction of the first ventilation holes 143 is parallel to the extending direction of the heat dissipation fins 311; the side surface of the surrounding portion 141 in the horizontal direction of the heat sink 31 is provided with a second ventilation hole 144, and the extending direction of the second ventilation hole 144 is perpendicular to the extending direction of the heat sink 311. The air flowing in through the first ventilation holes 143 flows into the heat dissipation air path 312 between the respective fins 311 shown in fig. 9 from above and below, and the air flowing in through the second ventilation holes 144 flows into the auxiliary heat dissipation air path 314 between the respective sub-fins 313 shown in fig. 9 from the side surfaces of the fins 311, and flows into the heat dissipation air path 312 through the auxiliary heat dissipation air path 314. After the air flows into the heat dissipation air duct 312, the air flows horizontally along the heat dissipation air duct 312 and flows out of the heat dissipation air duct 312 under the suction of the fan assembly 20 shown in fig. 1, so as to take away the heat of the heat dissipation member 31.

In some embodiments, as shown in fig. 14, the length of the heat sink 311 extending into the space surrounded by the enclosure 141 is greater than the maximum distance from the through hole to the outer edge of the enclosure 141. It is understood that the heat sink 31 is inserted into the fitting opening 14 in fig. 3 in a direction perpendicular to the extending direction of the heat sink 311 (the extending direction of the heat sink 311 is shown by a solid line joint in fig. 14). In the insertion direction of the heat sink 31 (the insertion direction is shown by a dotted arrow in fig. 14), one end of the heat sink 311 is connected to the electronic control housing 321 to form a connection end of the heat sink 311, and the other end of the heat sink 311 extends in the insertion direction to form a free end of the heat sink 311; one end of the surrounding portion 141 is connected to the housing 10 to form a connection end of the surrounding portion 141, the other end of the surrounding portion 141 extends along the insertion direction to form a free end of the surrounding portion 141, and the free end of the surrounding portion 141 is an outer edge of the surrounding portion 141. At least one ventilation hole 142 is provided between the connection end of the surrounding barrier portion 141 and the free end of the surrounding barrier portion 141. In the inserting direction, the distance between the vent hole 142 farthest from the free end of the surrounding portion 141 and the free end of the surrounding portion 141 is smaller than the distance between the free end of the cooling fin 311 and the connecting end of the cooling fin 311, so that the distance between at least one vent hole 142 and the connecting end of the cooling fin 311 is smaller than a preset threshold value, and therefore air flowing in from the vent hole 142 can flow into the cooling air duct between the cooling fins 311 from the connecting portion of the cooling fin 311 and flow out after flowing through the whole cooling air duct along the inserting direction, the contact area and the contact time between the air flowing in from the vent hole 142 and the cooling fin 311 are further increased, heat exchange between the air and the cooling fin 311 is more sufficient, and the heat dissipation effect of the cooling fin 31 on electronic control and 30 is further improved.

In some embodiments, as shown in fig. 14, adjacent cooling fins 311 are spaced apart by a distance greater than or equal to the distance between adjacent ventilation holes 142, so as to increase the surface area of the cooling member 31 and allow more airflow to flow through the cooling air duct 314, thereby further improving the cooling effect of the cooling member 31 on the electrical control box 30.

In some embodiments, the fan assembly 20 includes an indoor fan assembly and an outdoor fan assembly, the housing 10 of FIG. 1 is formed with an indoor region within which the indoor fan assembly and the evaporator are disposed and an outdoor region within which the outdoor fan assembly and the condenser are disposed, and the heat sink 31 of FIG. 1 is at least partially located within a duct that communicates with the outdoor region.
