Some mobile air conditioners also use refrigerant to dissipate heat from the electronic control box. However, due to the low temperature of the refrigerant and the large temperature difference between the refrigerant and the electronic control box, condensation can easily form inside the control box, compromising its safety.

[0050] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0051] like Figures 1 to 6 As shown, the heat dissipation system 10 of the present embodiment includes an air duct assembly 1, an electrical control box 2, an evaporator 3, and a water diversion assembly. The air duct assembly 1 includes a cold air duct 111 and a cold air blower 12. The cold air blower 12 is disposed within the cold air duct 111. A first inlet 121 communicating with the cold air duct 111 is provided above the cold air blower 12. The electrical control box 2 is disposed above the cold air duct 111, with a vertical gap between the electrical control box 2 and the first inlet 121. The evaporator 3 is disposed at the cold air inlet of the cold air duct 111.

[0052] When the heat dissipation system 10 of the disclosed embodiment is working, the air flow, driven by the cold air blower 12, enters the cold air duct 111 through the cold air inlet of the cold air duct 111, and exchanges heat with the evaporator 3 when passing through the evaporator 3, thereby cooling the air flow entering the cold air duct 111, so that the temperature of the air flow in the cold air duct 111 is relatively low; thereafter, the air flow enters the cold air blower 12 through the first inlet 121 of the cold air blower 12. Since the electrical control box 2 is arranged on the upper side of the cold air duct 111 and the temperature of the electrical control box 2 is higher than the temperature of the air flow in the cold air duct 111, the air flow in the cold air duct 111 will undergo heat exchange with the electrical control box 2 before entering the first inlet 121, thereby achieving air cooling and heat dissipation of the electrical control box 2; finally, the air flow in the cold air duct 111 is discharged to the outside through the cold air outlet 113 of the cold air duct 111, and the heat of the electrical control box 2 is discharged to the outside. Furthermore, the condensed water produced by the evaporator 3 is transported by the water diversion assembly to the electrical control box 2, achieving water cooling and heat dissipation of the electrical control box 2. Since the temperature difference between the condensed water and the electrical control box 2 is small, condensation in the electrical control box 2 can be effectively avoided, thereby improving the safety of the electrical control box 2.

[0053] Thus, the heat dissipation system 10 of the disclosed embodiment can not only cool the electric control box 2 with air, but also with water, effectively improving the heat dissipation effect of the electric control box 2. This avoids the need for fins on the electric control box 2 and reduces the overall size of the heat dissipation system 10. Furthermore, the use of condensed water to cool the electric control box 2 effectively prevents condensation within the electric control box 2, thereby improving the safety of the electric control box 2. Furthermore, a vertical gap is provided between the electric control box 2 and the first inlet 121, preventing the electric control box 2 from affecting the air intake area of the first inlet 121 and increasing the air volume of the cold air duct 111.

[0054] In some embodiments, as Figure 3 and Figure 4As shown, the distance between the electric control box 2 and the first inlet 121 in the vertical direction is 3 cm to 5 cm.

[0055] For example, Figure 3 and Figure 4 As shown, the distance between the electric control box 2 and the first inlet 121 in the vertical direction is H, and H is 4 cm.

[0056] It can be understood that the larger the distance between the electrical control box 2 and the first inlet 121 in the vertical direction, the smaller the influence of the electrical control box 2 on the air inlet area of the first inlet 121, the larger the air volume of the cold air duct 111, but the height of the heat dissipation system 10 is also larger; the smaller the distance between the electrical control box 2 and the first inlet 121 in the vertical direction, the smaller the height of the heat dissipation system 10, but the greater the influence of the electrical control box 2 on the air inlet area of the first inlet 121, and the smaller the air volume of the cold air duct 111.

[0057] By setting the vertical distance between the electric control box 2 and the first inlet 121 to 3 cm to 5 cm, the air volume of the cold air duct 111 can be increased while the height of the heat dissipation system 10 is not too large.

[0058] Alternatively, as Figures 1 to 3 As shown, the air duct assembly 1 includes an air duct housing 11 , and the air duct housing 11 encloses the above-mentioned cold air duct 111 .

[0059] Alternatively, as Figures 1 to 3 As shown, the cold air inlet is horizontally arranged on at least one side of the cold air duct 111, and the cold air outlet 113 of the cold air duct 111 is horizontally arranged on at least one side of the cold air duct 111. A second inlet 122 communicating with the cold air duct 111 is provided on the lower side of the cold air blower 12.

[0060] For example, Figure 3 As shown, the cold air inlet is located at the rear side of the cold air duct 111, and the cold air outlet 113 is located at the front side of the cold air duct 111. When the heat dissipation system 10 is in operation, the airflow, driven by the cold air blower 12, first flows through the evaporator 3 from back to front, then splits into two streams, entering the interior of the cold air blower 12 from a first inlet 121 located on the upper side of the cold air blower 12 and a second inlet 122 located on the lower side of the cold air blower 12, respectively, and finally flows out from the back to front through the cold air outlet 113.

[0061] By performing the above-mentioned design on the cold air duct 111 and the cold air blower 12 , the cold air duct 111 has a larger air intake volume, thereby further increasing the air volume of the cold air duct 111 .

[0062] Alternatively, as Figure 3As shown, the air duct assembly 1 includes a hot air duct 114, a hot air blower 13, and a condenser 30. The hot air duct 114 is arranged on the lower side of the cold air duct 111, and the hot air blower 13 is arranged in the hot air duct 114. The condenser 30 is arranged at the hot air inlet of the hot air duct 114. The hot air duct 114 can be surrounded by the air duct housing 11.

[0063] like Figure 3 As shown, when the heat dissipation system 10 of the embodiment of the present disclosure is working, the air flow enters the hot air duct 114 through the hot air inlet of the hot air duct 114 under the drive of the hot air blower 13, and exchanges heat with the condenser 30 when passing through the condenser 30; thereafter, the air flow enters the hot air blower 13 through the third inlet 131 of the hot air blower 13; finally, the air flow in the hot air duct 114 is discharged to the outside through the hot air outlet 115.

[0064] In some embodiments, as Figures 3 to 6 As shown, the electric control box 2 includes an electric control board 21 and a heat sink 22 . The heat sink 22 is disposed on the lower side of the electric control board 21 and contacts the electric control board 21 .

[0065] When the heat dissipation system 10 is working, the heat generated by the electronic control board 21 is transferred to the radiator 22 , and then the heat is transferred to the outside through the radiator 22 .

[0066] By providing the heat sink 22 in contact with the electric control board 21 , the heat dissipation area of the electric control box 2 can be increased, thereby further improving the heat dissipation effect of the electric control box 2 .

[0067] Alternatively, as Figures 8 to 10 As shown, a heat dissipation channel 221 is provided in the radiator 22, and the water guide assembly is connected to the heat dissipation channel 221. The heat dissipation channel 221 can be a U-shaped channel, a serpentine channel, a Z-shaped channel, etc.

[0068] By providing the heat dissipation channel 221 in the radiator 22 , condensed water can be introduced into the interior of the radiator 22 , thereby improving the heat dissipation effect of the radiator 22 , which is beneficial to further improving the heat dissipation effect of the electric control box 2 .

[0069] Alternatively, as Figure 5 and Figure 6 As shown, a mounting opening 1121 is provided on the upper side of the cold air duct 111 , and at least a portion of the radiator 22 extends into the cold air duct 111 through the mounting opening 1121 .

[0070] By extending at least a portion of the radiator 22 into the cold air duct 111, the airflow in the cold air duct 111 can dissipate heat from the radiator 22, thereby improving the heat dissipation effect of the radiator 22, thereby indirectly dissipating heat to the electronic control board 21, which is beneficial to further improve the heat dissipation effect of the electronic control box 2.

[0071] The heat sink 22 and the electronic control board 21 can be bonded together using thermally conductive adhesive, or connected using fasteners or snaps. A heat conducting member can be provided between the heat sink 22 and the electronic control board 21 to increase the contact area between the electronic control board 21 and the heat sink 22. The high thermal conductivity member can be a thermal pad or thermally conductive foam.

[0072] Alternatively, as Figure 5 and Figure 6 As shown, the air duct assembly 1 includes a mounting frame 112 , the mounting frame 112 is connected to the cooling air blower 12 , the electric control box 2 is connected to the mounting frame 112 , and a mounting port 1121 is provided on the mounting frame 112 .

[0073] For example, the mounting bracket 112 is connected to the volute of the cooling fan 12. The mounting bracket 112 and the volute of the cooling fan 12 can be connected by snapping or fasteners. The electrical control box 2 and the mounting bracket 112 can be connected by snapping or fasteners. The fasteners can be bolts, screws, rivets, etc.

[0074] By providing the mounting frame 112, the electric control box 2 can be first mounted on the mounting frame 112, and then the mounting frame 112 is connected to the cooling air blower 12 to achieve the connection between the electric control box 2 and the air duct assembly 1. Thus, the installation and fixation of the electric control box 2 is facilitated.

[0075] Optionally, the mounting frame 12 , the radiator 22 and the volute of the cold air blower 12 form a cold air duct 111 .

[0076] Alternatively, as Figures 3 to 6 As shown, the electric control box 2 includes a box body 23 , the electric control board 21 is arranged in the box body 23 , and an escape portion 231 is provided on the upper portion of the box body 23 .

[0077] For example, Figure 3 As shown, a portion of the box body 23 is arranged tilted so that an escape opening is formed at the upper portion of the box body 23 , and the escape opening forms an escape portion 231 .

[0078] By providing an avoidance portion 231 on the upper part of the box body 23, it is possible to avoid the upper components of the cooling system 10, thereby improving the compactness of the layout between the cooling system 10 and other components, and helping to reduce the overall height of electrical equipment (such as mobile air conditioners) having the cooling system 10.

[0079] like Figures 5 to 8 As shown, the water guide assembly includes a water receiving tray 4 and a water guide pipe 5. The water receiving tray 4 is arranged on the lower side of the evaporator 3 to receive the condensed water of the evaporator 3. The water in the water receiving tray 4 is transported to the electric control box 2 through the water guide pipe 5.

[0080] During operation, the condensed water generated by the evaporator 3 is collected by the water receiving pan 4 , and the water in the water receiving pan 4 is transported to the electric control box 2 through the water guide pipe 5 , thereby cooling and dissipating the heat of the electric control box 2 .

[0081] The water diversion component is configured as the above structure, which simplifies the structure of the water diversion component and helps reduce the cost of the heat dissipation system 100.

[0082] Alternatively, as Figure 5 、 Figure 7 and Figure 8 As shown, the water diversion assembly also includes a condensed water tank 6 and a water pump 7. The condensed water tank 6 is connected to the water receiving tray 4, and the water diversion pipe 5 is connected to the condensed water tank 6. The water pump 7 is used to drive the water in the condensed water tank 6 to flow into the water diversion pipe 5.

[0083] The water pump 7 may be a submersible pump and placed below the liquid level of the condensing water tank 6. One end of the water diversion pipe 5 is connected to the water pump 7, and the other end of the water diversion pipe 5 is connected to the heat dissipation channel 221.

[0084] By providing a condensed water tank 6, the condensed water in the water receiving pan 4 can be stored in the condensed water tank 6, which facilitates intermittent water cooling of the electronic control box 2. By providing a water pump 7, the flow rate of the condensed water in the water pipe 5 can be conveniently controlled to control the heat dissipation efficiency of the electronic control box 2 as needed.

[0085] Optionally, a temperature sensor is provided in the electric control box 2. When the temperature detected by the temperature sensor is lower than a preset temperature, the water pump 7 is not turned on, and only air cooling is performed on the electric control box 2. When the temperature detected by the temperature sensor is equal to or higher than the preset temperature, the water pump is turned on to direct the water in the condensation water tank 6 into the water diversion pipe 5, and the condensation water is guided to the electric control box 2 through the water diversion pipe 5. The electric control box 2 is cooled by both air and water, thereby improving the heat dissipation effect of the electric control box 2. The preset temperature may be 60°C.

[0086] Alternatively, as Figure 5 and Figure 7 As shown, the condensed water tank 6 is arranged on the lower side of the water receiving tray 4.

[0087] By setting the condensation water tank 6 on the lower side of the water receiving tray 4, the water in the water receiving tray 4 can flow into the condensation water tank 6 by its own gravity, avoiding the need to set other components between the water receiving tray 4 and the condensation water tank 6. In this way, the structure of the heat dissipation system 10 can be simplified and the cost of the heat dissipation system 10 can be reduced.

[0088] Alternatively, as Figure 5 、 Figure 7 and Figure 8As shown, the heat dissipation system 10 also includes a drainage box 8 and a drainage pipe 9. One end of the drainage pipe 9 is connected to the drainage box 8, and the other end of the drainage pipe 9 extends to the electric control box 2 so that water in the electric control box 2 flows into the drainage box 8.

[0089] For example, one end of the drain pipe 9 is connected to the heat dissipation channel 221 , and the other end of the drain pipe 9 is connected to the drain box 8 .

[0090] Therefore, after the condensed water cools and dissipates the heat of the electric control box 2, it can be discharged into the drainage box 8 through the drainage pipe 9, so as to realize the collection and subsequent treatment of the condensed water and avoid turbulent flow of the condensed water, which affects the user experience.

[0091] Optionally, the drainage box 8 is provided on the lower side of the electric control box 2 .

[0092] By placing the drain box 8 below the electrical box 2, water in the electrical box 2 can drain into the drain box 8 by gravity through the drain pipe 9, eliminating the need for a water flow driver (e.g., a water pump). This simplifies the structure of the heat dissipation system 10 and reduces its cost.

[0093] Optionally, the water inlet pipe 5 and the drainage pipe 9 are both flexible pipes.

[0094] As a result, the water diversion pipe 5 and the drainage pipe 9 can be bent, which facilitates the layout of the water diversion pipe 5 and the drainage pipe 9.

[0095] Optionally, the cold air blower 12 and the hot air blower 13 are driven by coaxial motors.

[0096] Therefore, the structure of the heat dissipation system 10 can be further simplified, and the cost of the heat dissipation system 10 can be reduced.

[0097] like Figures 1 to 12 As shown, the mobile air conditioner 100 of the embodiment of the present disclosure includes a housing 20 and a heat dissipation system 10 . The heat dissipation system 10 is the heat dissipation system 10 of any of the above embodiments, and the heat dissipation system 10 is disposed in the housing 20 .

[0098] The mobile air conditioner 100 further includes a compressor 40 .

[0099] When the mobile air conditioner 100 of the embodiment of the present disclosure is working, the airflow in the cold air duct 111 dissipates heat to the electric control box 2. After the mobile air conditioner 100 has been working for a period of time, the condensed water generated by the evaporator 3 is collected in the condensed water tank 6. When the temperature in the electric control box 2 is greater than or equal to the preset temperature, the water pump 7 is started, and the condensed water in the condensed water tank 6 is transported to the radiator 22 of the electric control box 2 through the water pipe 5, so as to water-cool the electric control box 2. By using the airflow in the cold air duct 111 to dissipate heat to the electric control box 2 by forced convection, and by using the condensed water to dissipate heat to the electric control box 2, dual cooling of the electric control box 2 is achieved, which can improve the operational reliability of the electric control box 2. Since the temperature of the condensed water is close to the temperature of the airflow in the cold air duct 111, compared with the refrigerant heat dissipation method in the related art, the condensation problem of the electric control box 2 can be avoided.

[0100] In the mobile air conditioner 100 of the disclosed embodiment, the airflow in the cold air duct 111 performs forced convection heat dissipation on the electric control box 2, and the electric control box 2 is water-cooled by condensed water, thereby improving the heat dissipation effect of the electric control box 2. This makes it possible to remove the heat dissipation fins of the electric control box 2, saving the internal space of the mobile air conditioner 100. The overall height of the mobile air conditioner 100 can be reduced by 3 cm to 5 cm, saving the material, packaging and transportation costs of the mobile air conditioner 100.

[0101] Although the embodiments of the present disclosure have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present disclosure. Any changes, modifications, substitutions and variations of the above embodiments by those skilled in the art are all within the scope of protection of the present disclosure.
