Please refer to FIGS. 1-3. As shown in the figures, the heat exchange device for a portable refrigeration appliance provided by the embodiment of the present invention includes a bottom plate 20 with an air outlet 21 and an air inlet 22 in the housing 10, and is fixedly arranged at the The support member 30 of the air inlet 22 , the air induction mechanism 40 disposed between the air inlet 22 and the support member 30 , and the first microchannel condenser 50 disposed on the other side of the support member 30 .

In this embodiment, the shell and the bottom plate cooperate to form a closed heat exchange space, and the heat exchange space is divided into a cold area and a hot area. The cold area and the hot area of the heat exchange compartment are completely separated, and the air in the cold area is sucked into the hot area through the micro-channel condenser by an axial flow fan, so as to carry out efficient heat exchange. Since the micro-channel condenser is used, the entire heat exchange device has a compact structure, which is suitable for installation and use in portable refrigeration appliances.

In some embodiments, the air induction mechanism 40 is an axial flow fan, and the axial flow fan has three blades made of plastic material. Using the blades made of plastic material can reduce the overall weight of the fan, reduce motor load and input power consumption . Through the rotation of the axial flow fan, the cooling energy generated by the first microchannel condenser is blown to the part to be cooled. Due to the rotation of the axial flow fan, the pressure in the heat exchange device shell is greater than the external pressure, and the heat exchanged gas passes through Outlet exhaust.

Further, the axial flow fan 40 and the first microchannel condenser 50 are coaxially disposed on both sides of the support member. By arranging the axial flow fan 40 coaxially with the first microchannel condenser 50 , the cold air generated by the first microchannel condenser 50 can be better drawn out.

In some embodiments, as shown in FIG. 3 , the support 30 includes a body 31 , a first folded edge 310 provided on the body 31 , and a first folded edge 310 provided on the body 31 . The second folded edge 320 perpendicular to 310 and the third folded edge 330 arranged on the main body 31 and parallel to the edge of the first folded 310 are provided with a cold air outlet 340 in the middle of the main body 31 .

Specifically, the support member 30 is a metal square bracket, and a cold air port 340 is opened in the middle of the metal square bracket for the passage of cold air generated by the micro-channel condenser. The first folded edge 310 is provided with a fixing position for fixing with the bottom plate, and usually the first folded edge 310 faces the direction of the air outlet. The third folded edge 330 faces the first microchannel condenser, and when installed, the third folded edge 330 covers the top of the first microchannel condenser to protect the first microchannel condenser 50 . A screw hole 321 for fixing with the casing 10 is provided on one end of the second folded edge 320 away from the bottom plate 20 . The support bracket can be firmly fixed on the casing by screws.

In some embodiments, the bottom plate 20 may be a quadrilateral design, such as a rectangle or a square. The air outlet 21 and the air inlet 22 are respectively arranged at both ends of the quadrilateral bottom plate, and the shape of the air outlet 21 and the air inlet 22 may be a plurality of square openings arranged in parallel, or a circular opening.

In some embodiments, the air outlet 21 and the air inlet 22 on the illustrated bottom plate 20 may be located on the same plane, that is, the bottom plate 20 is a flat plate, and the air outlet 21 and the air inlet 22 are located at two ends of the flat plate . Of course, the plane where the air inlet is located and the plane where the air outlet is located can also be located on different planes according to actual needs. For example, the plane where the air outlet is located can be set at a certain inclination angle to the plane where the air inlet is located. By setting the plane where the air inlet and the air outlet are located at a certain angle, different usage spaces can be satisfied.

In some embodiments, the air inlet 22 is provided with a filter screen for filtering. By arranging the filter screen, dust can be prevented from entering the first microchannel condenser 50 , which affects the normal operation of the first microchannel condenser 50 .

In some embodiments, the heat exchange device for portable refrigeration appliances further includes a second microchannel condenser 60 (not shown in the figure), the second microchannel condenser 60 is disposed in the axial flow The air outlet side of the fan 40 .

Specifically, in order to enhance heat exchange, two microchannel condensers can be arranged to work together to increase the cooling capacity. By arranging the second microchannel condenser on the air outlet side of the axial flow fan, the cold air generated by the second microchannel condenser can be taken away by the wind blown by the fan, thereby enhancing heat exchange. It should be noted that the first microchannel condenser 50 and the second microchannel condenser 60 are identical in structure.

Further, the illustrated first microchannel condenser 50 is connected in series with the second microchannel condenser 60 . Space can be saved by connecting in series, and it is suitable for applications with relatively narrow width and long length. Of course, the connection mode of the two micro-channel condensers can also be changed according to the actual use environment, such as parallel connection.

As shown in Figure 4-5, the direction of the arrow in the figure is the direction of air flow. It is a heat exchange room of a refrigeration appliance with embedded installation requirements. The fan sucks the cold air from the air inlet and enters the hot zone through the condenser, cools the compressor and the control box, and discharges it out of the room through the air outlet.

In summary, the present invention provides a heat exchange device for a portable refrigeration appliance, the heat exchange device for a portable refrigeration appliance includes a casing, a bottom plate with an air outlet and an air inlet, and is fixedly arranged at the The support piece of the air inlet, the air induction mechanism arranged between the air inlet and the support piece, and the first micro-channel condenser arranged on the other side of the support piece. The heat exchange compartment is designed in a closed type, and the heat exchange space is divided into a cold area and a hot area. The air inlet and air outlet are reserved in the cold area and the hot area respectively. The hot zone is completely separated, and the air in the cold zone is sucked into the hot zone through the micro-channel condenser with an axial flow fan, so as to conduct efficient heat exchange. Because the micro-channel condenser is used, the volume of the whole heat exchange device is small and does not take up too much space.

It should be understood that the application of the present invention is not limited to the above-mentioned examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above descriptions. All these improvements and transformations should belong to the protection of the appended claims of the present invention. scope.
