[0036] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0037] As Figures 1 to 3 shown, the air duct assembly 10 of the embodiment of the present disclosure includes an air duct housing 1 and an electric control box 2. The air duct housing 1 has a cold air duct 11 and a hot air duct 12. The cold air duct 11 is arranged on one side of the hot air duct 12 in the up-down direction, and the electric control box 2 is arranged on the side of the cold air duct 11 away from the hot air duct 12. Among them, the electric control box 2 can be a main electric control box or a variable-frequency electric control box.

[0038] For the air duct assembly 10 of the embodiment of the present disclosure, by arranging the electric control box 2 on the side of the cold air duct 11 away from the hot air duct 12, since the temperature at the cold air duct 11 is lower than that at the hot air duct 12, the temperature outside the electric control box 2 is relatively low, so that the heat of the electric control box 2 can be transferred to the outside, improving the heat dissipation effect of the electric control box 2 and the reliability of the electric control box 2.

[0039] In some embodiments, as Figure 3 shown, the cold air duct 11 is arranged parallel to the hot air duct 12, and the electric control box 2 is arranged parallel to the cold air duct 11.

[0040] For example, as Figure 3 shown, the cold air duct 11 is arranged on the upper side of the hot air duct 12, and the electric control box 2 is arranged on the upper side of the cold air duct 11.

[0041] By arranging the cold air duct 11 parallel to the hot air duct 12 and the electric control box 2 parallel to the cold air duct 11, a relatively large contact area can be formed between the electric control box 2 and the cold air duct 11, further improving the heat dissipation effect of the electric control box 2 and enhancing the reliability of the electric control box 2.

[0042] In some embodiments, as Figure 3 and Figure 4 shown, the air duct assembly 10 further includes a radiator 3, and the radiator 3 is connected to the electric control box 2. The air duct housing 1 has a first opening 13 communicating with the cold air duct 11, and at least a part of the radiator 3 extends into the cold air duct 11 through the first opening 13. Among them, the electric control box 2 and the radiator 3 can be snap-connected or connected by fasteners.

[0043] By providing the radiator 3, the heat of the electric control box 2 can be transferred to the radiator 3, and then the heat is transferred into the cold air duct 11 through the radiator 3, realizing the cooling and heat dissipation of the electric control box 2.

[0044] It can be understood that the temperature in the cold air duct 11 is not only relatively low, but also when the air duct assembly 10 is operating, the air flow in the cold air duct 11 will flow, thereby improving the heat exchange efficiency between the radiator 3 and the cold air duct 11, further enhancing the heat dissipation efficiency of the electric control box 2 and the reliability of the electric control box 2.

[0045] Optionally, as Figure 4 shown, the air duct housing 1 is provided with a first sealing portion 14, and the electric control box 2 is provided with a second sealing portion 22. Both the first sealing portion 14 and the second sealing portion 22 are arranged around the first opening 13, and the second sealing portion 22 is in contact with the first sealing portion 14.

[0046] It can be understood that the temperature inside the cold air duct 11 is relatively low, and the temperature inside the electric control box 2 is relatively high, with a large temperature difference between the inside of the electric control box 2 and the inside of the cold air duct 11. If the air flow in the cold air duct 11 directly exchanges heat with the electric control box 2, it is likely to cause condensation problems inside the electric control box 2, affecting the safety of the electric control box 2.

[0047] By making the second sealing portion 22 in contact with the first sealing portion 14, the sealing between the electric control box 2 and the air duct housing 1 can be achieved, preventing the air flow in the cold air duct 11 from entering the gap between the electric control box 2 and the air duct housing 1 and directly contacting the electric control box 2. Thus, the risk of condensation problems inside the electric control box 2 is reduced, and the safety of the electric control box 2 is enhanced.

[0048] Optionally, as Figure 4 and Figure 5 shown, the air duct housing 1 is provided with a first folded edge, and the electric control box 2 is provided with a second folded edge. The second folded edge is in contact with the first folded edge, and the first folded edge forms the first sealing portion 14, and the second folded edge forms the second sealing portion 22.

[0049] For example, as Figure 4 shown, the first folding edge extends in the up - and - down direction, the second folding edge extends in the up - and - down direction, the second folding edge is inserted inside the first folding edge, and the outer peripheral surface of the second folding edge fits with the inner peripheral surface of the first folding edge, realizing the seal between the air duct housing 1 and the electronic control box 2.

[0050] By forming the first sealing portion 14 on the first folding edge and the second sealing portion 22 on the second folding edge, the sealing area between the electronic control box 2 and the air duct housing 1 can be increased, the sealing performance between the electronic control box 2 and the air duct housing 1 can be improved, the risk of condensation problems occurring inside the electronic control box 2 can be further reduced, and the safety of the electronic control box 2 can be improved.

[0051] Optionally, a first sealing member is provided between the first sealing portion 14 and the second sealing portion 22. Among them, the first sealing member can be a sealing foam, a sealing ring, etc.

[0052] By providing a first sealing member between the first sealing portion 14 and the second sealing portion 22, the sealing performance between the electronic control box 2 and the air duct housing 1 can be improved, the risk of condensation problems occurring inside the electronic control box 2 can be further reduced, and the safety of the electronic control box 2 can be improved.

[0053] In some embodiments, as Figure 4 shown, the electronic control box 2 includes a box body 21, the box body 21 is provided with a second opening 211, and a part of the radiator 3 extends into the box body 21 through the second opening 211.

[0054] By extending a part of the radiator 3 into the box body 21, the distance between the radiator 3 and the electrical components inside the electronic control box 2 is relatively close, and even can be in direct contact with the electrical components of the electronic control box 2, so that the heat dissipation effect of the electronic control box 2 can be further improved, and the reliability of the electronic control box 2 can be improved.

[0055] Optionally, as Figure 4 , Figure 6 and Figure 7 shown, the box body 21 is provided with a third sealing portion 212, the radiator 3 is provided with a fourth sealing portion 31, and the fourth sealing portion 31 fits with the third sealing portion 212.

[0056] It can be understood that the temperature inside the cold air duct 11 is relatively low, the temperature inside the electronic control box 2 is relatively high, and the temperature difference between the inside of the electronic control box 2 and the inside of the cold air duct 11 is relatively large. If the air flow inside the cold air duct 11 directly exchanges heat with the electronic control box 2, it is easy to cause condensation problems inside the electronic control box 2, affecting the safety of the electronic control box 2.

[0057] By attaching the fourth sealing portion 31 to the third sealing portion 212, the sealing between the electronic control box 2 and the radiator 3 can be achieved, preventing the air flow in the cold air duct 11 from entering the gap between the electronic control box 2 and the radiator 3 and directly contacting the electronic control box 2. Thereby, the risk of condensation problems occurring inside the electronic control box 2 is reduced, and the safety of the electronic control box 2 is improved.

[0058] Optionally, as Figure 4 and Figure 7 shown, the third sealing portion 212 is disposed around the second opening 211, and the third sealing portion 212 is disposed around the second opening 211. <m

[0059] Thereby, the air flow in the cold air duct 11 can be prevented from entering the interior of the box body 21 through the second opening 211, the risk of condensation problems occurring inside the electronic control box 2 is reduced, and the safety of the electronic control box 2 is improved.

[0060] Optionally, as Figure 4 and Figure 7 shown, the electronic control box 2 is provided with a third flanging, the outer peripheral surface of the radiator 3 is attached to the third flanging, the third flanging forms the third sealing portion 212, and the outer peripheral surface of the radiator 3 forms the fourth sealing portion 31.

[0061] For example, as Figure 4 shown, the second flanging is used as the third flanging, the third flanging extends in the up and down direction, a part of the radiator 3 is inserted into the opening surrounded by the third flanging, and the outer peripheral surface of the radiator 3 is attached to the inner peripheral surface of the third flanging to achieve the sealing between the radiator 3 and the electronic control box 2.

[0062] By forming the third sealing portion 212 with the third flanging and forming the fourth sealing portion 31 with the outer peripheral surface of the radiator 3, the sealing area between the electronic control box 2 and the radiator 3 can be increased, the sealing performance between the electronic control box 2 and the radiator 3 can be improved, the risk of condensation problems occurring inside the electronic control box 2 can be further reduced, and the safety of the electronic control box 2 can be improved.

[0063] Optionally, a second sealing member is provided between the third sealing portion 212 and the fourth sealing portion 31. Among them, the second sealing member can be a sealing foam, a sealing ring, etc.

[0064] By providing a second sealing member between the third sealing portion 212 and the fourth sealing portion 31, the sealing performance between the electronic control box 2 and the radiator 3 can be improved, the risk of condensation problems occurring inside the electronic control box 2 can be further reduced, and the safety of the electronic control box 2 can be improved.

[0065] As Figures 1 to 3 、 Figure 8 shown, the mobile air conditioner 100 of the embodiment of the present disclosure includes a housing 20 and a duct assembly 10. The duct assembly 10 is the duct assembly 10 described in any of the above embodiments, and the duct assembly 10 is disposed inside the housing 20.

[0068] When the mobile air conditioner 100 operates in a refrigeration mode, indoor air enters the cold air duct 11 through the cold air inlet, exchanges heat with the evaporator assembly 30, and then flows into the room through the cold air outlet. At the same time, indoor air enters the hot air duct 12 through the hot air inlet, exchanges heat with the condenser assembly 40, and then flows out of the room through the hot air outlet, thus achieving refrigeration. When the mobile air conditioner 100 operates in a heating mode, indoor air enters the cold air duct 11 through the cold air inlet, exchanges heat with the evaporator assembly 30, and then flows out of the room through the cold air outlet. At the same time, indoor air enters the hot air duct 12 through the hot air inlet, exchanges heat with the condenser assembly 40, and then flows into the room through the hot air outlet, thus achieving heating.
