[0034] Compared with traditional vertical or hanging air conditioners, mobile air conditioners are smaller in size, more portable and do not require installation, and are chosen by more and more users. In the related art, mobile air conditioners are provided with a condensing chamber and an evaporating chamber, which are generally arranged up and down, wherein both the condensing chamber and the evaporating chamber are provided with an air inlet. The air inlet of the evaporating chamber of the existing mobile air conditioner has a small air intake, resulting in low heat exchange efficiency of the evaporating chamber of the mobile air conditioner.

[0035] In view of the technical problems existing in the prior art, the utility model proposes a heat exchange structure, which improves the heat exchange efficiency of the condensing chamber by improving the structure of the evaporator and the air supply volute. Specifically, the evaporator is designed to be an L-shaped structure, and the outer shell of the air conditioner is provided with two air inlets, which increases the air impact volume of the evaporator. At the same time, the air supply volute is designed to have upper and lower air inlets, which increases the air output.

[0036] Reference Figure 1 and Figure 2The heat exchange structure of the first embodiment of the utility model includes a housing 100, a first volute 200 and an evaporator 310. Specifically, the inner cavity of the housing 100 is formed with a first heat exchange area 400 and a second heat exchange area 410. The first heat exchange area 400 is an evaporation chamber, and the evaporation chamber is provided with an evaporator 310 assembly. The second heat exchange area 410 is a condensation chamber, and the condensation chamber is provided with a condenser assembly. The housing 100 is provided with a first air inlet 110, a second air inlet 120 and an air outlet 130 at the first heat exchange area 400. The first air inlet 110, the second air inlet 120 and the air outlet 130 are all connected to the inner cavity of the housing 100. The first volute 200 is disposed in the first heat exchange area 400. The first volute 200 is provided with a mounting portion 210 and an air supply portion 220. The air supply cavity 221 is located inside the air supply portion 220. The air supply portion 220 is provided with air inlets above and below. The air supply portion 220 is provided with an air outlet 222 on the side thereof. The air inlet and the air outlet 222 are both connected to the air supply cavity 221. The air outlet 222 is connected to the air outlet portion 130. The evaporator 310 is disposed in the first heat exchange area 400 and is located between the first air inlet 110 and the first volute 200, and between the second air inlet 120 and the first volute 200.

[0037] It should be noted that the mounting portion 210 and the evaporator 310 form a heat exchange air chamber 230, and the air inlet is connected to the heat exchange air chamber 230. Air can enter the inner chamber from the first air inlet 110 and the second air inlet 120. The air in the inner chamber can pass through the evaporator 310 for heat exchange and reach the heat exchange air chamber 230. The cold air in the heat exchange air chamber 230 can enter the air supply chamber 221 from the air inlet and flow to the outside from the air outlet 222.

[0038] Reference Figure 3 The evaporator 310 is provided with a first turning portion 311 and a second turning portion 312. The length direction of the first turning portion 311 is perpendicular to the length direction of the second turning portion 312. The first turning portion 311 corresponds to the position of the first air inlet portion 110, and the second turning portion 312 corresponds to the position of the second air inlet portion 120. Figure 1 As shown, the structure of the evaporator 310 is an L-shaped structure, and is installed after the first heat exchange area 400 . The evaporator 310 can cover the first air inlet 110 and the second air inlet 120 .

[0039] It should be noted that, in other embodiments, the evaporator 310 may be designed as a rectangular structure, with two evaporators 310 being located at the first air inlet 110 and the second air inlet 120 , respectively.

[0040] It can be understood that under the action of the fan, external air enters the heat exchange air chamber 230 from two air inlets at the same time, effectively increasing the amount of air entering the evaporation chamber. At the same time, the two air inlets of the first volute 200 further increase the air flow rate, thereby improving the heat exchange efficiency of the first heat exchange zone 400.

[0041] Reference Figure 2 A filter 320 is provided between the evaporator 310 and the housing 100 . The filter 320 can effectively reduce the insects and other debris that enter the heat exchange air chamber 230 , reduce the attachments on the surface of the evaporator 310 , and increase the contact amount between the air and the evaporator 310 .

[0042] It should be noted that the first air inlet 110 and the second air inlet 120 are both grid-like hollow structures, and the grid-like hollow structure has a certain guiding effect on the air, making the airflow more stable and reducing turbulence.

[0043] Reference Figure 4 and Figure 5 In order to facilitate the disassembly and assembly of the first volute 200, the first volute 200 is designed as a detachable splicing structure. Specifically, the first volute 200 is provided with a first part 240 and a second part 250, and the first part 240 and the second part 250 are spliced ​​up and down to form the first volute 200. The first part 240 and the second part 250 can be connected by screws or clamped by a splicing structure. In order to improve the sealing effect between the first part 240 and the second part 250, the first part 240 is provided with a first splicing portion 241, and the second part 250 is provided with a second splicing portion 251, and the first splicing portion 241 is inserted into the second splicing portion 251. A first groove is provided on the side of the first splicing portion 241 away from the air supply chamber 221, and a second groove is provided on the side of the second splicing portion 251 close to the air supply chamber 221, and the first splicing portion 241 can be clamped into the second groove, and the second splicing portion 251 can be clamped into the first groove.

[0044] Reference Figures 2 to 5 In order to make the air vertically enter the evaporator 310, the area of ​​the evaporator 310 projected onto the housing 100 is equal to the area of ​​the side of the evaporator 310 close to the housing 100. In some embodiments provided by the utility model, the evaporator 310 is arranged parallel to the side wall of the housing 100, wherein, when the evaporator 310 is an L-shaped structure, the first turning portion 311 is parallel to one side of the housing 100, and the second turning portion 312 is parallel to the other side of the housing 100. In order to prevent the air from directly entering the heat exchange air chamber 230 without passing through the evaporator 310, the areas of the first air inlet 110 and the second air inlet 120 are smaller than the area of ​​the evaporator 310 projected onto the housing 100.

[0045] Reference Figure 1 and Figure 2 The air conditioner provided in the second embodiment of the utility model includes the above-mentioned heat exchange structure, and the air conditioner can be a mobile air conditioner or a wall-mounted air conditioner, etc. Below the first heat exchange area 400 is the second heat exchange area 410, and the second heat exchange area 410 is equipped with a condenser assembly and a second volute 300, and the second volute 300 is used to supply air to the second heat exchange area 410.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
