However, in daily life, there are some scenes in which a small-sized refrigerator is required, such as storing cosmetics or temporarily storing things on an automobile. Therefore, it is required to reduce the size of the refrigerator to increase the convenience of the refrigerator.

After the volume of the refrigerator is reduced, the storage space of the small-sized refrigerator is also reduced.

Detailed Description

For the purposes of making the objects, technical solutions and advantages of the exemplary embodiments of the present application more apparent, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is apparent that the described exemplary embodiments are only some embodiments of the present application, but not all embodiments.

The semiconductor refrigerator is an electronic refrigerator which is cooled by a semiconductor chip, and the volume of the semiconductor chip is far smaller than that of a compressor, so that the semiconductor refrigerator is often applied to the field of small-sized refrigerators. The semiconductor chip is also called a thermoelectric refrigeration piece, and is a heat pump. The Peltier effect of the semiconductor material can be utilized, when direct current passes through a couple formed by connecting two different semiconductor materials in series, heat can be absorbed and released at two ends of the couple respectively, and the purpose of refrigeration is realized. The semiconductor chip has the advantage of no sliding parts and is often applied to occasions with limited space, high reliability requirement and incapability of being polluted by the refrigerant.

However, since the semiconductor chip is cooled by absorbing heat in the vicinity thereof, a certain diffusion time is required to lower the temperature in the entire refrigerator compartment, resulting in a decrease in the cooling efficiency of the refrigerator. In the process of refrigerating the semiconductor chip, condensed water is also generated by the air in the refrigerator due to the reduction of the temperature, and the refrigerating effect of the semiconductor chip is affected.

Based on the above application scenario, in order to alleviate the problem of low refrigeration efficiency of a small-sized refrigerator, some embodiments of the present application provide a refrigeration system, as shown in fig. 1, which includes a refrigeration module 100, an air cooling assembly 200, and a drainage assembly 300.

The refrigeration module 100 is used for absorbing heat and generating cool air to reduce the temperature of compartments in the refrigerator, i.e. the refrigeration module 100 is used for realizing a refrigeration function. In some embodiments, the refrigeration module 100 employs semiconductor refrigeration in order to reduce the overall size of the refrigerator. As shown in fig. 2, the refrigeration module 100 includes a cooling fin 110, a cooling block 120, a semiconductor chip 130 and a heat sink 140. The cold guide block 120 is fixedly connected with the semiconductor chip 130 to form a refrigerating mechanism. One end of the refrigerating mechanism is fixedly connected with the refrigerating plate 110, and the other end of the refrigerating mechanism is fixedly connected with the radiating fin 140.

In the embodiment of the present application, the temperature of one end of the semiconductor chip 130 absorbing heat gradually decreases, which is called cold end; the end of the semiconductor chip that emits heat gradually increases in temperature, referred to as the hot end. Then, the refrigeration module 100 composed of the semiconductor chips 130 is provided with the refrigeration sheet 110, the cold guide block 120, the semiconductor chips 130, and the heat sink 140, respectively, in order from the cold side to the hot side. The cold guide block 120 contacts with one end of the semiconductor chip 130 that absorbs heat to enhance the heat absorbing effect of the semiconductor chip 130 by increasing the contact area. The cold guide block 120 may be an aluminum block, which has high heat conduction efficiency and can quickly cool the semiconductor chip 130. Similarly, the cooling fins 110 and the heat sink 140 increase the heat absorption and dissipation effects of the semiconductor chip 130 by increasing the contact area.

In some embodiments, as shown in fig. 3, the refrigeration module 100 further includes a bolt 141 and a fixing buckle 142 adapted thereto, where the bolt 141 and the fixing buckle 142 may be fixedly connected by threads. The cooling plate 110 and the cooling plate 140 are fixedly connected by bolts 141 and fixing buckles 142, and the cooling block 120 and the semiconductor chip 130 are clamped therebetween to form a cooling module.

The air cooling assembly 200 is used for increasing the diffusion speed of cool air produced by the refrigeration module 100 to improve the refrigeration efficiency of the refrigeration system. As shown in fig. 4 and 5, the air cooling assembly 200 includes a cooling fan 210, a cooling air duct 220, a blowing port 221, and a return air port 222. The air blowing port 221 and the air returning port 222 are arranged on the refrigerating air duct 220, the refrigerating sheet 110 is arranged in the refrigerating air duct 220, and the refrigerating fan 210 is arranged at one end of the refrigerating air duct 220 close to the air blowing port 221. The cooling fan 210 may be a centrifugal fan, and when the cooling fan 210 operates, the centrifugal fan may achieve an axial air inlet and lateral air outlet effect. Thus, after the operation of the semiconductor chip 130, heat in the vicinity of the cooling fin 110 is absorbed, and cool air is generated. At this time, the cooling fan 210 provided in the same cooling duct 220 as the cooling fin 110 is operated, and cool air can be blown into the refrigerating compartment or the freezing compartment of the refrigerator through the air blowing port 221, thereby increasing the diffusion rate of the cool air. The air in the refrigerator compartment can be continuously circulated through the air blowing port 221 and the air return port 222 through the rotating refrigerating fan 210 to form a flowing wind field so as to improve the refrigerating effect of the refrigerating system.

In addition, the temperature in the refrigerator is reduced by the refrigerating module 100 during the refrigerating process, so that the temperature difference between the refrigerating sheet 110 and the air in the refrigerator compartment is generated. The temperature difference causes water molecules in the air to condense into liquid, and condensed water is generated. The condensed water is easy to have oxidation reaction with some elements of the refrigerator, and the service life of each element is shortened. And, the condensed water also affects the refrigerating effect of the refrigerating system. Therefore, the refrigerating system also discharges condensed water in time by arranging the drainage assembly 300 so as to ensure the refrigerating effect of the refrigerating system.

As shown in fig. 6, the drain assembly 300 includes a water receiving tray 310, a water guide groove 320, and an evaporation pan 330. The water pan 310 is disposed below the cooling plate 110 in the vertical direction to receive condensed water generated on the surface of the cooling plate 110. The water guide groove 320 is inclined in a vertical direction, and one end of the water guide groove 320 is connected to the water receiving tray 310, and the other end of the water guide groove 320 is connected to the evaporation pan 330. In this way, the condensed water can drip into the water receiving tray 310 under the action of gravity, and after the condensed water generated by the refrigeration module 100 is received by the water receiving tray 310, the condensed water can be guided into the evaporating dish 330 from the water receiving tray 310 by the water guiding groove 320. The evaporation pan 330 is used for evaporating the condensed water, i.e., evaporating the condensed water introduced from the water guide 320. For example, a vessel element with a heating wire may be employed.

To improve the water guiding efficiency of the water guiding groove 320, in some embodiments, as shown in fig. 6, the water draining assembly 300 further includes a water draining pipe 321, the water draining pipe 321 is disposed at the bottom of the water guiding groove 320, and an end of the water draining pipe 321 is fixed in the evaporating dish 330. In this way, the drain pipe 321 can better connect the water guide tank 320 with the evaporation pan 330, so as to reduce the problem of condensed water dripping from the connection part of the water guide tank 320 and the evaporation pan 330.

However, cold air in the refrigerator may be leaked due to the drain pipe 321 communicating with the evaporating dish 330. Thus, to reduce leakage of cold air, in some embodiments, drain assembly 300 further includes a choke post 3211, which choke post 3211 is disposed in drain 321 proximate evaporation pan 330. The air blocking column 3211 is made of a material with high water absorbability and low air permeability, such as sponge and silica gel. Thus, the condensed water can be smoothly discharged, and the leakage of the cold air in the refrigerator can be reduced through the obstruction of the air blocking column 3211.

As can be seen from the above embodiments, the water pan 310 can receive the condensed water dropped from the refrigeration module 100, but cannot drain the condensed water attached to the heat sink 140 in time. Accordingly, in order to timely drain the condensed water on the heat sink 140, the life span of the heat sink 140 is extended, and in some embodiments, the drain assembly 300 further includes a water absorbing string 340. One end of the water absorbing rope 340 is fixedly connected with the heat sink 140, and the other end of the water absorbing rope 340 is fixedly connected with the evaporating dish 330. The condensed water generated on the surface of the heat sink 140 is sucked into the water suction rope 340 by the water suction rope 340, and is introduced into the evaporation pan 330 by itself to be evaporated. Therefore, the water absorbing rope 340 should be made of a material having high water absorbability and mold and moisture resistance, such as cotton threads.

In addition, since the refrigeration module 100 absorbs heat, a large amount of heat is emitted. If more heat is accumulated in the refrigerating system, the environment in the periphery of the refrigerator is influenced, and the experience of a user is reduced. Accordingly, in some embodiments, heat dissipation of the refrigeration module is also enhanced by the heat dissipation assembly 400. As shown in fig. 4 and 7, the heat dissipation assembly 400 includes a heat dissipation fan 410, a heat dissipation air duct 420, an air suction inlet 421 and an air outlet 422. The air inlet 421 and the air outlet 422 are disposed on the heat dissipation air duct 420, so as to circulate the air of the heat dissipation air duct 420. The heat sink 140 is disposed in the heat dissipation air duct 420, and the heat dissipation fan 410 is disposed in the heat dissipation air duct 420 near the air suction port 421. Thus, when the cooling fan 410 is operated, air can be driven to rapidly dissipate heat generated by the cooling fins 140, and the heat generated by the cooling fins 140 is communicated with external air, so that the influence of the refrigeration system on the surrounding environment is reduced.

It is understood that the heat dissipation fan 410 and the refrigeration fan 210 may be of the same type, for example, centrifugal fans are used for both the heat dissipation fan and the refrigeration fan; alternatively, different types of fans may be employed. The present application is not limited in this regard.

Because each tuyere needs to circulate air, and the tuyere is of a regular or irregular through hole structure, dust is easy to bring into the refrigerator. Therefore, in some embodiments, the refrigeration system further includes a dust screen 500, and the air blowing port 221, the air return port 222, the air suction port 421 and the air outlet 422 are all through hole structures. The dust-proof net 500 covers the air blowing opening 221, the air return opening 222, the air suction opening 421, and the air outlet 422 to reduce the entry of dust.

According to the technical scheme, the refrigerating system provided by some embodiments of the application comprises a refrigerating module, an air cooling assembly and a drainage assembly. The refrigerating module comprises a refrigerating sheet, a cold guide block, a semiconductor chip and a radiating fin; the cold guide block is fixedly connected with the semiconductor chip to form a refrigerating mechanism. One end of the refrigerating mechanism is fixedly connected with the refrigerating sheet, and the other end is fixedly connected with the radiating sheet. The air cooling assembly comprises a refrigerating fan, a refrigerating air duct, an air blowing port and an air return port. The air blowing port and the air return port are arranged at two ends of the refrigerating air duct, the refrigerating sheet is arranged in the refrigerating air duct, and the refrigerating fan is arranged in the refrigerating air duct close to the air blowing port. The drainage component comprises a water receiving disc, a water guide groove and an evaporation dish; the water collector sets up in the below of refrigeration piece vertical direction, and the guiding gutter inclines in the vertical direction to set up. One end of the water guide groove is connected with the water receiving disc, and the other end is connected with the evaporating dish. The refrigerating system can accelerate the refrigerating rate of the refrigerating module through the air cooling assembly, timely discharges condensed water generated in the refrigerating process through the water draining assembly, and improves the refrigerating efficiency of the refrigerating system.
