Figures 1 to 8 shown.

[0050] The traditional refrigerator door is only used to open or close the refrigerator compartment. At most, a bottle holder is provided at the door lining of the refrigerator compartment to place bottles or other small items.

[0051] The composite door refrigerator improves the door 200 of the refrigerator, and is provided with a door compartment 201 with a refrigeration function on the door 200. The door 200 includes a main door 210 and a sub-door 220, wherein the sub-door 220 is used to open the door compartment 201 provided on the door 200. In this way, the door compartment 201 can be used to place items that need to be stored separately, such as cosmetics. When taking or placing, only the sub-door 220 needs to be opened, thereby avoiding the problem of cooling loss caused by frequent opening of the main door 210.

[0052] The refrigeration device provided in the embodiment of the present disclosure includes a box compartment 101 enclosed by a box body 100 and a door body 200, and a door compartment 201 arranged on the door body 200. The box compartment 101 may include a box refrigeration compartment and a box freezing compartment. The door compartment 201 may be a box refrigeration compartment.

[0053] The refrigeration system for cooling the box compartment 101 includes a refrigerant circulation system composed of a compressor 11, a condenser 12, a throttle valve 13 and an evaporator 14. Further, the box compartment 101 can be cooled by air cooling or direct cooling.

[0054] Optionally, the cabinet compartment 101 includes a cabinet refrigeration compartment arranged at the upper part and a cabinet freezer compartment arranged at the lower part, and the cabinet refrigeration compartment is close to the door compartment 201, and the cold transfer system is arranged between the cabinet refrigeration compartment and the door compartment 201, and the cold capacity of the cabinet refrigeration compartment is used to cool the door compartment 201.

[0055] Optionally, the cold transfer system includes a cold absorption end 21 and a cold release end 22. The cold absorption end 21 is arranged in the box compartment 101, and the cold release end 22 is arranged in the door compartment 201. The cold absorption end 21 absorbs cold energy from the box compartment 101, and the cold release end 22 releases cold energy to the door compartment 201, thereby realizing refrigeration of the door compartment 201. Optionally, the cold absorption end 21 is arranged in the box refrigeration compartment of the box 100.

[0056] The refrigeration system provided by the embodiment of the present disclosure adopts a cold transfer system to transfer the coldness of the box compartment 101 to the door compartment 201, so that the box compartment 101 and the door compartment 201 can be completely separated, thereby avoiding the problem of odor transfer between the two and bacteria entering the door compartment 201 through the air duct, thereby improving the storage quality of the door compartment 201 for items.

[0057] Optionally, the door body 200 includes a foaming layer 202 disposed between the door body compartment 201 and the box body compartment 101. The foaming layer 202 completely separates the door body compartment 201 from the box body compartment 101. Figure 4 shown.

[0058] Optionally, the cooling system further includes a first connecting pipe 23 and a second connecting pipe 24. The first connecting pipe 23 is connected to the outlet 212 of the cold absorption end and the inlet 221 of the cold release end; the second connecting pipe 24 is connected to the outlet 222 of the cold release end and the inlet 211 of the cold absorption end, wherein the cold absorption end 21, the first connecting pipe 23, the cold release end 22 and the second connecting pipe 24 form a closed loop. Figure 2 and Figure 3 shown.

[0059] The cold absorption end 21, the first connecting pipe 23, the cold release end 22 and the second connecting pipe 24 form a closed loop, and the closed loop is filled with a coolant. In this way, the cold absorption end 21 is arranged in the box compartment 101, and absorbs cold in the box compartment 101. After absorbing the cold, the temperature of the coolant decreases, and the low-temperature coolant transfers the cold to the cold release end 22 through the first connecting pipe 23. The cold release end 22 arranged in the door compartment 201 releases the cold, thereby realizing the refrigeration of the door compartment 201. After the cold is released, the temperature of the coolant rises, and the high-temperature coolant flows to the cold absorption end 21 through the second connecting pipe 24. In this way, a cold transfer cycle is realized.

[0060] Optionally, the first connecting pipeline 23 is provided with a first pump body 232; and / or the second connecting pipeline 24 is provided with a second pump body 242. Figure 3 shown.

[0061] The first connecting line 23 is provided with a first pump body 232, and the first pump body 232 can drive the coolant to flow from the outlet 212 of the cold suction end to the inlet 221 of the cold discharge end, thereby improving the fluidity of the coolant in the first connecting line 23. Similarly, the second connecting line 24 is provided with a second pump body 242, and the second pump body 242 can drive the coolant to flow from the outlet 222 of the cold discharge end to the inlet 211 of the cold suction end, thereby improving the fluidity of the coolant in the second connecting line 24.

[0062] Optionally, the start and stop of the cooling system can be controlled by controlling the opening or closing of the first pump body 232 or the second pump body 242. For example, when the temperature in the door body compartment 201 is greater than or equal to the first preset temperature, the first pump body 232 and the second pump body 242 are controlled to be turned on, and the cooling system is controlled to be turned on, and the cold in the box compartment 101 is transferred to the door compartment 201, thereby realizing the refrigeration of the door compartment 201. When the temperature in the door compartment 201 is less than or equal to the second preset temperature, the first pump body 232 and the second pump body 242 are controlled to be turned off, that is, the cooling system is controlled to be turned off, and the cooling from the box compartment 101 to the door compartment 201 is stopped. In this way, the effect of the traditional system in transferring cooling to the door compartment 201 is improved, the frequent start and stop of the first pump body 232 and the second pump body 242 is avoided, the stability of the temperature in the door compartment 201 is improved, and at the same time, the efficiency of the traditional system in unidirectional cooling is improved.

[0063] Optionally, the first connecting pipeline 23 is provided with a first valve component 231, wherein the first valve component 231 includes a first valve conduction inlet end and a first valve conduction outflow end, and the cold absorption end 21 is arranged on the side of the first valve conduction inlet end, and the cold release end 22 is arranged on the side of the second valve conduction outflow end.

[0064] The first connecting pipeline 23 is provided with a first valve component 231, which can be a one-way valve, including a first valve conduction inlet end and a first valve conduction outlet end, so as to control the one-way flow of the coolant from the outlet 212 of the cold absorption end to the inlet 221 of the cold release end.

[0065] Optionally, the second connecting pipe 24 is provided with a second valve component 241, wherein the second valve component 241 includes a second valve conduction inlet end and a second valve conduction outflow end, and the cold release end 22 is arranged on the side of the second valve conduction inlet end, and the cold absorption end 21 is arranged on the side of the second valve conduction outflow end.

[0066] Similarly, the second connecting pipeline 24 is provided with a second valve component 241, which can be a one-way valve, including a second valve conductive inlet end and a second valve conductive outflow end. In this way, it is helpful to control the one-way flow of the coolant from the outlet 222 of the cold release end to the inlet 211 of the cold absorption end.

[0067] Optionally, the cold absorption end 21 includes a first heat exchanger, and the cold discharge end 22 includes a second heat exchanger, wherein the cold transfer system is filled with a coolant. Figures 1 to 4 shown.

[0068] The cold absorption end 21 includes a first heat exchanger, and the cold release end 22 includes a second heat exchanger. A refrigerant flow pipeline is provided in the first heat exchanger, and a refrigerant flow pipeline is also provided in the second heat exchanger. Optionally, the first heat exchanger includes a tube-fin heat exchanger, a microchannel heat exchanger, etc., and similarly, the second heat exchanger includes a tube-fin heat exchanger, a microchannel heat exchanger, etc. In this way, the cold absorption effect of the first heat exchanger on the box compartment 101 is improved, and at the same time, the cold release effect of the second heat exchanger to the door compartment 201 is improved.

[0069] Optionally, the cooling system further includes a liquid storage tank for storing a coolant.

[0070] The liquid storage tank is used to temporarily store the refrigerant in the cooling system. Optionally, the liquid storage tank is a cavity structure with a storage inner cavity disposed therein. The liquid storage tank is disposed in the first connecting pipeline 23 or the second connecting pipeline 24. Taking the liquid storage tank disposed in the first connecting pipeline 23 as an example, the liquid storage tank includes a liquid inlet and a liquid outlet. At the same time, the liquid storage tank is provided with a liquid storage inlet pipe connected to the first connecting pipeline 23 and the liquid inlet, and a liquid storage outlet pipe connected to the first connecting pipeline 23 and the liquid outlet. In addition, the liquid storage inlet pipe is provided with a third pump body, and the liquid storage outlet pipe is provided with a fourth pump body.

[0071] Optionally, when the temperature in the door body chamber 201 is greater than or equal to the first preset temperature, and the difference between the temperature in the door body chamber 201 and the set temperature is less than or equal to the first preset temperature difference, it is considered that the cooling capacity required by the current door body chamber 201 is not large. At this time, the third pump body and the fourth pump body can be controlled to open, so that part of the refrigerant in the first connecting pipe 23 flows into the liquid storage tank for temporary storage, thereby reducing the amount of refrigerant actually participating in the cooling cycle.

[0072] Optionally, when the temperature in the door body chamber 201 is greater than or equal to the first preset temperature, and the difference between the temperature in the door body chamber 201 and the set temperature is greater than or equal to the second preset temperature difference, it is considered that the cooling capacity required by the current door body chamber 201 is large. At this time, the third pump body and the fourth pump body can be controlled to open, so that the refrigerant in the liquid storage tank flows into the first connecting pipeline 23 to participate in the cold transfer cycle. In this way, the amount of refrigerant actually participating in the cold transfer cycle is increased.

[0073] Optionally, when the temperature in the box compartment 101 is less than or equal to the third preset temperature, and the temperature in the door compartment 201 is also less than or equal to the set temperature, it is considered that the box compartment 101 has excess cold capacity to be transferred to the door compartment 201. However, when the door compartment 201 does not need to be refrigerated, the third pump body can be controlled to be turned on and the fourth pump body can be turned off to temporarily store the low-temperature coolant after the cold absorption end 21 absorbs the cold in the liquid storage tank. When the temperature in the door compartment 201 rises and needs to be refrigerated, the fourth pump body is controlled to be turned on to use the low-temperature coolant stored in the liquid storage tank to refrigerate the door compartment 201. In this way, the cooling effect of the cooling system is improved.

[0074] The cold absorption end 21 includes a heat pipe condensation end, and the cold release end 22 includes a heat pipe evaporation end, wherein the heat pipe condensation end is set at a first height, the heat pipe evaporation end is set at a second height, and the first height is greater than the second height. Figure 5 shown.

[0075] The heat pipe condensing end and the heat pipe evaporating end constitute a heat pipe cooling system. The heat pipe cooling system can be a loop heat pipe or a pulsating heat pipe.

[0076] The loop heat pipe is a highly efficient heat transfer device that can be used in various high-temperature, high-density, high-energy, and high-precision thermal management fields. It has the characteristics of simple structure, high efficiency, good reliability, large heat transfer distance, and anti-gravity operation. The heat pipe cooling circulation pipeline adopts a loop heat pipe, which can greatly improve the cooling efficiency.

[0077] Pulsating heat pipe is also a closed loop in structure. It can ensure that the fluid flows in one direction in the loop by setting at least one flow control valve. Pulsating heat pipe is composed of a series of serpentine-arranged and interconnected capillaries. It does not require a wick, has a simple structure and low cost. The driving force for the pulsation and annular flow of the working fluid in the pipe comes from the pulsating heat pipe itself, and no external driving equipment is required. Pulsating heat pipe has the advantages of efficient heat transfer, long life, safety and reliability.

[0078] The heat pipe condensation end and the heat pipe evaporation end constitute a heat pipe cooling system. The heat pipe condensation end is arranged in the box compartment 101, so that the heat pipe condensation end can receive the coldness of the box compartment 101. Optionally, the heat pipe condensation end is close to the air outlet of the box compartment 101, for example, the heat pipe condensation end is arranged below the air outlet of the box compartment 101, so that the heat pipe condensation end improves the coldness receiving effect.

[0079] Optionally, the door body 200 includes a foam insulation layer 202 arranged between the box body chamber 101 and the door body chamber 201, wherein the first connecting pipe 23 is provided with a first heat pipe insulation section 2311, and at least a portion of the first heat pipe insulation section 2311 is arranged in the foam insulation layer 202; and / or the second connecting pipe 24 is provided with a second heat pipe insulation section 2411, and at least a portion of the second heat pipe insulation section 2411 is arranged in the foam insulation layer 202.

[0080] An insulating section is provided in the heat pipe cooling system. The setting of the insulating section avoids the influence of the external environment of the cooling system on the cold transfer, improves the cold transfer efficiency between the heat pipe condensing end and the heat pipe evaporating end, and further improves the cooling efficiency of the heat pipe evaporating end to the door chamber 201.

[0081] A foam interlayer 202 is arranged between the box compartment 101 and the door compartment 201, at least a portion of the first heat pipe insulation section 2311 is penetrated through the foam interlayer 202, and at least a portion of the second heat pipe insulation section 2411 is penetrated through the foam interlayer 202. The foam interlayer 202 of the refrigerator is used for insulation, and the length of the insulation section is greater than or equal to the thickness of the foam interlayer 202. In this way, the temperature isolation effect between the box compartment 101 and the door compartment 201 is improved, and the accuracy of the temperature control of the door compartment 201 by the heat pipe cooling system is further improved.

[0082] Optionally, the evaporation end of the heat pipe further includes an evaporation end radiator 223 .

[0083] Optionally, the evaporation end radiator 223 includes an aluminum extrusion radiator, a temperature balancing plate radiator, etc. The provision of the evaporation end radiator 223 improves the cooling efficiency and cooling uniformity of the heat pipe type cooling end 22 to the door body compartment 201 .
