As shown in FIG. 1 , an embodiment of the present disclosure provides a device for removing condensation from a refrigerator. The refrigerator includes a box body and a door. The device includes an air supply system 100 for decondensation disposed on the box body and/or door. Side; the air supply system 100 includes an air suction box 10 and an air supply device 20 connected with the air suction box 10. The air supply device 20 has an air supply area 221, and the plane of the air supply area 221 is aligned with the side of the box or door. At a set angle; the air suction box 10 is used to suck air and send the inhaled air to the air supply device 20. The air supply device 20 supplies air around the refrigerator through the air supply area 221 to speed up the cooling of the refrigerator around the outer surface. Air flow rate.

Using the device for removing condensation in a refrigerator provided by the embodiment of the present disclosure, the air supply system 100 is disposed on the side of the refrigerator box and/or the door. In this way, the disturbance of the air supply system 100 accelerates the movement near the outer surface of the refrigerator. The air circulation increases the natural convection heat transfer coefficient on the outer surface of the refrigerator and avoids condensation on the outer surface of the refrigerator. Among them, the air supply system 100 includes an air suction box 10 and an air supply device 20 connected with the air suction box 10. The air supply device 20 has an air supply area 221, and the plane of the air supply area 221 is aligned with the side of the box or door. Set the angle; in this way, it not only accelerates the air circulation near the outer surface of the refrigerator through the wind disturbance at the set angle, but also optimizes the space occupied by the air duct; in addition, the air suction box is used to suck air and send the inhaled wind into As for the air supply device, the air supply device supplies air around the refrigerator through the air supply area. This improves the utilization of the air supply system, speeds up the air flow around the outer surface of the refrigerator, and further prevents condensation on the surface of the refrigerator.

In the embodiment of the present disclosure, as shown in FIG. 7 , the refrigerator includes a box body 300 and a box door 200 . Among them, through the joint calculation of the first law of thermodynamics, Fourier's law and Newton's cooling formula:

h ₁ (t ₁ -t ₂ )=λ (t ₂ -t ₃ )/L=h ₂ (t ₃ -t ₄ )

Among them, t ₁ is the ambient temperature; t ₂ is the outer surface temperature of the box door; t ₃ is the inner surface temperature of the box door; t ₄ is the internal temperature of the box; h ₁ is the convection coefficient between the air and the outer surface of the box door; λ is the box The thermal conductivity of the door foam material; h ₂ is the convection heat transfer coefficient of the inner surface of the door; L is the thickness of the door foam layer.

Here, take the ambient temperature as 32°C as an example. At this time, the measured outer surface temperature t ₂ of the box door is 29.5°C; the inner surface temperature t ₃ of the box door is -16°C; the internal temperature t ₄ of the box body is -18°C; the thermal conductivity coefficient λ of the door foam material is 0.020 [ W/(mK)]; the convection coefficient h ₁ between the air and the outer surface of the box door is 6[W/(m2.K)]; the convection heat transfer coefficient h ₂ on the inner surface of the box door is 25[W/(m2.K) ]; The thickness L of the foam layer of the door is 50mm.

When the thickness L of the door foam layer is 50 mm, it can be obtained from the above formula that h ₁ =λ(t ₂ -t ₃ )/(t ₁ -t ₂ )L. Among them, as shown in Figure 8, it is the change curve of the door outer surface temperature t ₂ with the door outer surface convection heat transfer coefficient h ₁ .

It can be seen from Figure 8 that there is a proportional relationship between the convection heat transfer coefficient h ₁ on the outer surface of the box door and the temperature t ₂ on the outer surface of the box door. Therefore, when the value of h ₁ is low, it means that the outer surface of the box door is less disturbed, the air flow velocity is lower, and the convection heat transfer intensity between the air and the outer surface of the box door is weak. Less cold energy is taken away from the door, making the outer surface temperature t ₂ of the door lower. When the temperature of the outer surface of the door is lower than the dew point, condensation is easy to occur on the outer surface of the door. When the value of h ₁ is higher, it means that the outer surface of the box door is more disturbed, the air flow velocity is higher, and the convection heat transfer intensity between the air and the outer surface of the box door is higher. More cold energy is taken away from the door, making the outer surface temperature t ₂ of the door higher. When the temperature of the outer surface of the door is higher than the dew point, the outer surface of the door is less likely to condense.

When the door outer surface temperature t ₂ is 29.5°C, it can be obtained from the above formula that L=λ(t ₂ -t ₃ )/h ₁ (t ₁ -t ₂ ). Among them, as shown in Figure 9, it is the change curve of the thickness L of the door foam layer with the convection heat transfer coefficient h ₁ of the door surface.

It can be seen from Figure 9 that when the value of h ₁ is low, it means that the outer surface of the door is less disturbed, the air flow rate is lower, and the convection heat transfer intensity between the air and the outer surface of the door is weak. In order to maintain the outer surface temperature of the door at 29.5°C, it is necessary to increase the thermal resistance of the door, such as increasing the thickness of the foam layer of the door. When the h ₁ value is higher, it means that the outer surface of the box door is more disturbed, the air flow velocity is higher, and the convection heat transfer intensity between the air and the outer surface of the box door is higher. In order to maintain the outer surface temperature of the door at 29.5°C, it is necessary to reduce the thermal resistance of the door, such as reducing the thickness of the foam layer of the door. Therefore, it can be seen from the above analysis that when the convection heat transfer coefficient h ₁ of the outer surface of the box door is increased, the temperature of the outer surface of the box door can be effectively increased to prevent condensation.

In the embodiment of the present disclosure, the door of the refrigerator includes, but is not limited to, the refrigeration door, the freezing door, and the variable temperature door; the box of the refrigerator includes, but is not limited to, the side panels, the top panel, and the back panel of the box.
