Detailed Description

The utility model will now be described in further detail with reference to the drawings and specific examples, which are not intended to limit the utility model thereto.

Referring to fig. 1 to 7, according to an embodiment of the present utility model, there is provided a refrigerator including a water tank 10 disposed inside a cabinet, a heat exchanger 20, and a centrifugal fan 30, the water tank 10 for receiving defrost water of the refrigerator; the heat exchanger 20 is arranged inside the water tank 10; the centrifugal fan 30 is arranged above the heat exchanger 20, and the heat exchanger 20 is positioned at the air inlet position of the centrifugal fan 30.

The refrigerator introduces the defrosting water in the water collector into the bottom of the water tank, the defrosting water flows into the water tank and then is accumulated at the bottom of the water tank, when the centrifugal fan rotates, accumulated water at the bottom of the water tank is upwards adsorbed, a water film is formed firstly, then the water film is broken and separated into liquid drops by fins on the heat exchanger, the liquid drops are distributed on the fins and the heat exchange tubes of the heat exchanger (condenser), and the defrosting water is used for efficiently cooling the heat exchanger (condenser). The defrosting water is partially evaporated after contacting with a heat exchanger (condenser) to form water vapor which is discharged by a centrifugal fan, so that a water mist heat dissipation effect is formed, and the water cooling efficiency is higher than that of air cooling, so that even if only a narrow bottom space exists, the heat dissipation effect is very outstanding. In conclusion, the refrigerator disclosed by the utility model can effectively dissipate heat, and even an embedded refrigerator can ensure heat dissipation and improve the running stability and energy efficiency of the refrigerator.

In the compressor cavity at refrigerator back, left side places the compressor, and the right side places the water tank, and heat exchanger (condenser) is placed and is fixed and upper strata is sealed with the sideboard in the water tank, and heat exchanger (condenser) only exposes the fin. And a centrifugal fan is arranged above the heat exchanger (condenser) at a distance d, and only an air inlet is exposed between the centrifugal fan and the condenser.

Preferably, the heat exchanger 20 has fins; a predetermined distance L0 (not shown) is provided between the bottom surface of the heat exchanger 20 and the bottom surface of the water tank 10; the maximum height of the defrost water collected inside the tank 10 is L1 (see fig. 3), L1 < L0.

Because defrosting water quantity is less, L1 is generally smaller than the distance L0 between the bottom surface of the condenser and the bottom surface of the water tank, only the soaking fins are not directly formed or partially soaked, the occurrence of the condition that the heat exchanger is damaged due to rust and the like caused by fin soaking is avoided, the service life of the heat exchanger can be prolonged, the long-term use stability of the refrigerator is ensured, and the service life of the refrigerator is prolonged.

Referring to fig. 3, when the rotation speed of the centrifugal fan is N0, the adsorption force is F1, so that the accumulated water at the bottom of the water tank can be adsorbed upwards, a water film is formed first, then the upward process is continued, the accumulated water is broken and separated into liquid drops by the fins and is distributed on the condenser fins and the heat exchange tube, and the overall adsorption height of the accumulated water is L2.

As shown in fig. 2 and fig. 4, the centrifugal fan 30 includes a first centrifugal fan 31 and a second centrifugal fan 32, and the rated rotation speed of the first centrifugal fan 31 is a first rotation speed N1; the rated rotation speed of the second centrifugal fan 32 is a second rotation speed N2, and the second centrifugal fan 32 and the first centrifugal fan 31 are arranged side by side; the first centrifugal fan 31 and the second centrifugal fan 32 can be independently operated, and N2 > N1.

Because defrosting water is not much, when the rotating speed of the centrifugal fan is high and the adsorption force is large, defrosting water is easy to quickly evaporate or part of defrosting water is directly discharged, so that accumulated water is not fully utilized, and meanwhile, the heat exchange temperature difference of the whole condenser is uneven, so that the whole performance is also influenced. Therefore, in order to maximize the utilization of the defrost water, the present utility model provides different rotational speeds of the left and right centrifugal fans (the first centrifugal fan 31 and the second centrifugal fan 32) and is matched with the condenser flow path arrangement.

The second centrifugal fan is positioned on the left side of the figure 4, the second centrifugal fan is controlled to perform partial heat exchange for the condenser, the condensation temperature is higher at the moment, the rotating speed N2 is more than N1, the adsorption force is large, and the adsorption height is L3. The first centrifugal fan is positioned on the right in fig. 4, the rotating speed N1 is low, the adsorption force is small, and the adsorption height of the first centrifugal fan is L4, and L4 is less than L3. The differential adsorption effect can ensure that the partial fins and the heat exchange tubes of the entered condenser exchange heat with the water film preferentially, are easier to evaporate and fully utilize. The heat exchange adsorption height of the outlet part of the condenser is low, and a water film and water drops are not easy to be directly sucked out and thrown out by the first centrifugal fan, so that waste is avoided. And the refrigerant in the condenser can be condensed into liquid state (condensation temperature) in a shorter stroke, and the refrigerant is cooled by the water film adsorbed by the first centrifugal fan for the second time when flowing out, so that the higher supercooling degree is achieved, and the whole performance is beneficial.

Of course, when the operation is particularly required, the first centrifugal fan 31 and the second centrifugal fan 32 can be controlled to operate respectively, and the first centrifugal fan 31 and the second centrifugal fan 32 can operate simultaneously or separately, and can be particularly blended according to the defrosting water and the actual requirement.

The heat exchange effect of the heat exchanger (condenser) of the present utility model is optimized in consideration of the selection of uniform heat exchange, and in this embodiment, the area of the first centrifugal fan 31 covering the heat exchanger 20 is the same as the area of the second centrifugal fan 32 covering the heat exchanger 20; the heat exchanger 20 covers the air inlet of the first centrifugal fan 31 and the air inlet of the second centrifugal fan 32. That is, the air entering from the bottom of the water tank must pass through the heat exchanger before entering the air inlet of the first centrifugal fan 31 and the air inlet of the second centrifugal fan 32. Moreover, the two centrifugal fans respectively cover the same heat exchanger area, so that air can exchange heat with fins and heat exchange tubes of the heat exchanger more uniformly, the heat exchange area of the heat exchanger is fully utilized, the heat exchange efficiency is improved, and the aim of improving heat dissipation is fulfilled.
