Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, for example, to a reinforced iron component for refrigeration equipment and refrigeration equipment. Background Art

[0002] At present, with the improvement of people's living standards, the freshness of food storage has received more and more attention, especially the freshness storage of high-end ingredients. Low-temperature storage, especially storage in a temperature zone below -50℃, can greatly improve the quality and storage period of food. For example, the taste of wild yellow croaker will obviously decrease after being stored in a regular refrigerator for one month, but it will still taste fresh after being stored at -60℃ for half a year.

[0003] Existing refrigerators or freezers can use cascade refrigeration technology to achieve low-temperature storage. Cascade refrigeration technology generally requires two compressors. Related technology discloses a refrigerator compressor compartment foam layer reinforced iron structure, including U-shaped reinforcement iron, vertical reinforcement iron and L-shaped reinforcement iron. The first end of the vertical reinforcement iron is arranged at the two end corners of the U-shaped reinforcement iron, the first end of the L-shaped reinforcement iron is clamped with the end of the U-shaped reinforcement iron, and the second end of the L-shaped reinforcement iron is welded to the second end of the vertical reinforcement iron.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The reinforcing iron in the related technology is suitable for conventional compressor cabins. When two or more compressors are installed in the compressor cabin, the compressor cabin needs to bear the weight of the two or more compressors, which increases the strength requirements of the reinforcing iron. The reinforcing iron in the related technology is not strong enough, which can easily cause damage to the refrigeration equipment during transportation and cause losses.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0010] An embodiment of the present disclosure provides a refrigeration device, and the refrigeration device includes a reinforcing iron component for the refrigeration device as described in any one of the above embodiments.

[0011] The reinforced iron assembly for refrigeration equipment and the refrigeration equipment provided in the embodiments of the present disclosure can achieve the following technical effects:

[0012] The frame of the disclosed embodiment can play a role in reinforcing the foam layer and the compressor cabin.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] Combination Figures 1 to 20 As shown, the embodiment of the present disclosure provides a refrigeration device, which can provide a low-temperature environment to store food, medicine or other items at low temperatures. For example, the refrigeration device can be a refrigerator, a freezer, a freezer, a biomedical refrigeration device or other refrigeration device.

[0045] The refrigeration equipment includes a cascade refrigeration system, which may be a two-stage cascade cycle system, a three-stage cascade cycle system, or a four-stage cascade cycle system, and the number of cascade stages is not specifically limited. This embodiment is only exemplified by a cascade refrigeration system with a two-stage cascade cycle system, and those skilled in the art should be fully capable of expanding on this basis.

[0046] like Figures 1 to 4As shown, the embodiment of the present disclosure provides a cascade refrigeration system, which includes a high-temperature refrigeration cycle 10 and a low-temperature refrigeration cycle 20. A first refrigerant circulates in the high-temperature refrigeration cycle 10, and a second refrigerant circulates in the low-temperature refrigeration cycle 20. The high-temperature refrigeration cycle 10 includes an evaporation portion 101, a high-temperature compressor 102, a first pipeline 103, a high-temperature condenser 104, a high-temperature throttling device 105, and a second pipeline 106. The first pipeline 103 is connected between the outlet of the evaporation portion 101 and the inlet of the high-temperature compressor 102; the high-temperature condenser 104 is connected to the outlet of the high-temperature compressor 102; the inlet of the high-temperature throttling device 105 is connected to the outlet of the high-temperature condenser 104, and the outlet of the high-temperature throttling device 105 is connected to the inlet of the evaporation portion 101; the second pipeline 106 is connected between the outlet of the high-temperature condenser 104 and the inlet of the high-temperature throttling device 105.

[0047] The low temperature refrigeration cycle 20 includes a condensing part 201, a low temperature compressor 202, a third pipeline 203, a low temperature evaporator 204, a fourth pipeline 205 and a low temperature throttling device 206. The condensing part 201 and the evaporating part 101 form an evaporative condenser 30, and the second refrigerant in the condensing part 201 can exchange heat with the first refrigerant in the evaporating part 101; the third pipeline 203 is connected between the outlet of the low temperature compressor 202 and the inlet of the condensing part 201; the inlet of the low temperature evaporator 204 is connected to the outlet of the condensing part 201; the fourth pipeline 205 is connected between the outlet of the low temperature evaporator 204 and the inlet of the low temperature compressor 202; the inlet of the low temperature throttling device 206 is connected to the outlet of the condensing part 201, and the outlet of the low temperature throttling device 206 is connected to the low temperature evaporator 204.

[0048] In the disclosed embodiment, the evaporation part 101 in the high-temperature refrigeration cycle 10 can exchange heat with the evaporation part 101 of the low-temperature refrigeration system, so that the first refrigerant in the high-temperature refrigeration cycle 10 can be used to cool the second refrigerant in the low-temperature refrigeration cycle 20, that is, the first refrigerant in the evaporation part 101 absorbs the heat of the second refrigerant in the condensation part 201 to achieve the cooling of the second refrigerant, and then the cooled second refrigerant is further cooled by the low-temperature refrigeration cycle 20, thereby achieving the low temperature of the refrigeration equipment. The low-temperature throttling part 206 and the high-temperature throttling part 105 can both be capillaries or electronic expansion valves.

[0049] Optionally, the evaporation part 101 includes an evaporation tube, and the condensation part 201 includes a condensation tube, and the evaporation tube and the condensation tube are close to each other (fitted or close to each other) to achieve heat exchange between the evaporation tube and the condensation tube. Optionally, the evaporation part 101 and the condensation part 201 can also be in the form of a sleeve to achieve heat exchange.

[0050] Optionally, the high temperature refrigeration cycle 10 further includes a third filter dryer 307, which is located between the high temperature condenser 104 and the high temperature throttling member 105. The low temperature refrigeration cycle 20 further includes a second filter dryer 306, which is located between the condensing portion 201 and the low temperature throttling member 206.

[0051] Alternatively, if Figure 1 As shown, the high-temperature stage throttling element 105 is connected or in contact with the first pipeline 103 to form a return air pipe group 304, and the return air pipe group 304 is used to exchange heat between the first refrigerant in the high-temperature stage throttling element 105 and the first refrigerant in the first pipeline 103. In this way, after the first refrigerant after heat exchange between the evaporation part 101 and the condensation part 201 flows along the first pipeline 103 to the return air pipe group 304, the first refrigerant in the first pipeline 103 exchanges heat with the high-temperature stage throttling element 105 to become a low-pressure and normal-temperature gaseous refrigerant, and then enters the high-temperature stage compressor 102 to complete the cycle. Here, the return air pipe group 304 can cool down the first refrigerant flowing through the high-temperature stage throttling element 105, thereby reducing the temperature of the first refrigerant flowing into the evaporation part 101, and improving the heat exchange efficiency in the evaporative condenser 30.

[0052] The first refrigerant in the high-temperature refrigeration cycle loop 10 is pressurized by the high-temperature compressor 102 to form a high-temperature and high-pressure superheated gas. After entering the high-temperature condenser 104, it is condensed into a supercooled liquid or a saturated liquid or a gas-liquid two-phase. Then, after passing through the third drying filter 307 to filter out moisture and impurities, it enters the high-temperature throttling device 105 of the return air pipe group 304 for throttling and cooling. After throttling by the high-temperature throttling device 105, the first refrigerant becomes a low-temperature and low-pressure state and enters the cold end pipe of the evaporative condenser 30 to release the cold. After that, it returns to the return air pipe group 304 along the first pipeline 103, and after heat exchange with the high-temperature throttling device 105, it becomes a low-pressure and normal-temperature refrigerant gas, and enters the high-temperature compressor 102 to complete the cycle.

[0053] The second refrigerant in the low-temperature refrigerant circulation loop is compressed and pressurized by the low-temperature compressor 202 to form a high-temperature and high-pressure superheated gas. After passing through the third pipeline 203, it enters the condenser of the evaporative condenser 30 to dissipate heat and become a supercooled liquid or a saturated liquid or a gas-liquid two-phase. Then, it enters the low-temperature throttling device 206 to throttle to a low-temperature and low-pressure state and enters the low-temperature evaporator 204 for refrigeration, so that low-temperature storage below -45°C can be achieved. After the second refrigerant absorbs heat in the low-temperature evaporator 204 and becomes a superheated gas, it is sucked into the low-temperature compressor 202 to complete the refrigeration cycle. Optionally, the high-temperature throttling device 105 and the first pipeline 103 use close contact heat exchange or sleeve heat exchange to exchange heat.

[0054] In some optional embodiments, such as Figure 2As shown, the third pipeline 203 and the fourth pipeline 205 are connected or in contact with each other and form a first regenerator 301 , and the first regenerator 301 is used to exchange heat between the second refrigerant in the third pipeline 203 and the second refrigerant in the fourth pipeline 205 .

[0055] In the disclosed embodiment, the third pipe 203 in the first regenerator 301 can be regarded as the hot end of the first regenerator 301, and the fourth pipe 205 in the first regenerator 301 can be regarded as the cold end of the first regenerator 301. The second refrigerant in the low-temperature refrigeration cycle is compressed and pressurized by the low-temperature compressor 202 to form a high-temperature and high-pressure superheated gas. After flowing into the first regenerator 301 through the third pipe 203, it dissipates heat in the first regenerator 301, and part of the second refrigerant becomes a gas-liquid two-phase state. Then, the second refrigerant after heat dissipation enters the condenser of the evaporative condenser 30, dissipates heat, and becomes a supercooled liquid or a saturated liquid or a gas-liquid two-phase state. Then, it enters the low-temperature throttling device 206 to throttle to a low-temperature and low-pressure state and enters the low-temperature evaporator 204 for refrigeration, so that low-temperature storage below -45°C can be achieved. After the second refrigerant absorbs heat in the low-temperature evaporator 204, it flows into the cold end of the first regenerator 301 through the fourth pipeline 205, absorbs the heat of the hot end to become superheated gas, and is sucked into the low-temperature compressor 202 to complete the refrigeration cycle. Here, the setting of the first regenerator 301 can reduce the temperature difference between the fourth pipeline 205 and the ambient temperature, thereby solving the problem that the fourth pipeline 205 of the low-temperature refrigeration cycle 20 is easy to frost, especially the problem that the fourth pipeline 205 is easy to frost in the compressor cabin 403.

[0056] Optionally, the third pipeline 203 and the fourth pipeline 205 perform heat exchange by contact heat exchange or in the form of sleeve heat exchange.

[0057] Optionally, the cascade refrigeration system further includes a first filter dryer 305, which is disposed in the third pipeline 203 and is located between the outlet of the first regenerator 301 and the inlet of the evaporative condenser 30. Here, the first filter dryer 305 can filter the second refrigerant flowing out of the first regenerator 301 after heat exchange before flowing into the evaporative condenser 30, thereby reducing impurities flowing into the condensation part 201 and improving the heat exchange efficiency of the evaporative condenser 30.

[0058] like Figure 3 As shown, optionally, the low-temperature refrigeration cycle loop 20 also includes a precooling pipe 308 , and the precooling pipe 308 is arranged in the third pipeline 203 .

[0059] In the disclosed embodiment, the precooling pipe 308 is used as a "condenser", which can be used to cool the low-temperature refrigerant output by the low-temperature compressor 202, thereby reducing the heat load of the low-temperature refrigerant subsequently output to the evaporative condenser 30, so that the low-temperature refrigerant output from the evaporative condenser 30 can reach a lower temperature. The second refrigerant in the low-temperature refrigerant circulation loop is compressed and pressurized by the low-temperature compressor 202 to form a high-temperature and high-pressure superheated gas, which flows into the precooling pipe 308 along the third pipeline 203 for precooling, so that the temperature of the high-temperature and high-pressure superheated gas is reduced to close to the ambient temperature, thereby improving the subsequent heat exchange efficiency of the second refrigerant.

[0060] Alternatively, if Figure 3 As shown, the low-temperature refrigeration cycle 20 includes a precooling pipe 308, a hot end of the first regenerator 301 and a first filter dryer 305 arranged in sequence along the flow direction of the second refrigerant, and the cold pipe 308 is located upstream of the first regenerator 301. After the second refrigerant flowing through the cold pipe 308 flows into the first regenerator 301 through the third pipe 203, it dissipates heat in the first regenerator 301, and part of the second refrigerant becomes a gas-liquid two-phase state. Then, the second refrigerant after heat dissipation is filtered by the first filter dryer 305 and flows into the condenser of the evaporative condenser 30. After heat dissipation, it becomes a supercooled liquid or a saturated liquid or a gas-liquid two-phase state, and then enters the low-temperature throttling device 206 to throttle to a low temperature and low pressure state and enter the low-temperature evaporator 204 for refrigeration, so that low-temperature storage below -45°C can be achieved. After absorbing heat in the low-temperature evaporator 204, the second refrigerant flows into the cold end of the first regenerator 301 through the fourth pipe 205, absorbs the heat of the hot end and becomes a superheated gas, and is sucked into the low-temperature compressor 202 to complete the refrigeration cycle.

[0061] like Figure 4 As shown, in some other optional embodiments, the second pipeline 106 is in contact with or connected to the fourth pipeline 205 to form a second regenerator 302, and the second regenerator 302 is used to exchange heat between the first refrigerant in the second pipeline 106 and the second refrigerant in the fourth pipeline 205.

[0062] In the disclosed embodiment, the second pipe 106 in the second regenerator 302 is equivalent to the hot end of the second regenerator 302, and the fourth pipe 205 in the second regenerator 302 is equivalent to the cold end of the second regenerator 302. In this way, the second refrigerant in the high-temperature refrigeration cycle 10 flows through the high-temperature condenser 104 to become a supercooled liquid or a saturated liquid or a gas-liquid two-phase, and then enters the second regenerator 302, and after heat exchange with the second refrigerant in the fourth pipe 205 of the low-temperature refrigeration cycle 20, it flows to the high-temperature throttling device 105. In this way, the condensation temperature of the second refrigerant can be further reduced or the degree of supercooling can be increased. The second refrigerant after cooling down in the second regenerator 302 flows through the return air pipe group 304, and then exchanges heat with the high-temperature throttling device 105 to become a low-pressure and normal-temperature refrigerant gas, and enters the high-temperature compressor 102 to complete the cycle.

[0063] Optionally, the second pipeline 106 and the fourth pipeline 205 perform heat exchange by contact heat exchange or in the form of sleeve heat exchange.

[0064] Alternatively, if Figure 4 As shown, the low-temperature refrigeration cycle 20 includes a second regenerator 302, a precooling pipe 308 and a second drying filter 306. The precooling pipe 308 is arranged in the third pipeline 203, and the second drying filter 306 is located between the condensation part 201 and the low-temperature throttling device 206.

[0065] In the disclosed embodiment, the second refrigerant in the low-temperature refrigeration cycle is compressed and pressurized by the low-temperature compressor 202 to form a high-temperature and high-pressure superheated gas, which flows into the precooling pipe 308 along the third pipeline 203 for precooling, so that the temperature of the high-temperature and high-pressure superheated gas is reduced to close to the ambient temperature. After the heat dissipation, the second refrigerant enters the condenser of the evaporative condenser 30 and dissipates heat to become a supercooled liquid or a saturated liquid or a gas-liquid two-phase, and then enters the second drying filter 306 for filtration and enters the low-temperature throttling device 206 to throttle to a low-temperature and low-pressure state and enters the low-temperature evaporator 204 for refrigeration. The second drying filter 306 can avoid the blockage of the low-temperature throttling device 206. In this way, low-temperature storage below -45°C can be achieved. After the second refrigerant absorbs heat from the low-temperature evaporator 204, it flows into the cold end of the second regenerator 302 through the fourth pipeline 205. After absorbing the heat of the hot end and becoming a superheated gas, the problem of frost on the fourth pipeline 205 in the compressor cabin 403 can be solved, and then the second refrigerant is sucked into the low-temperature compressor 202 to complete the refrigeration cycle.

[0066] An embodiment of the present disclosure further provides a refrigeration device, which includes the cascade refrigeration system as described in any of the above embodiments.

[0067] The refrigeration device provided in the embodiment of the present disclosure includes the cascade refrigeration system described in any of the above embodiments, and thus has the beneficial effects of the cascade refrigeration system of any of the above embodiments, which will not be described in detail here.

[0068] The following description is based on the refrigeration equipment being a refrigerator, particularly a horizontal refrigerator:

[0069] The refrigeration equipment includes a box, such as Figure 6 As shown, the box body defines a compressor cabin 403, and the box body includes an inner liner 402 and an outer shell 401. The outer shell 401 is located outside the inner liner 402, and the outer shell 401 and the inner liner 402 enclose the compressor cabin 403. The inner liner 402 includes a plurality of enclosing panels, and the plurality of enclosing panels enclose an internal space. The plurality of enclosing panels include a bottom wall and a side wall. The side wall is connected to the end of the bottom wall and extends upward. The side walls are sequentially arranged along the circumference of the bottom wall. The side wall and the bottom wall enclose an internal space. The bottom wall portion of the inner liner 402 protrudes upward to form a step. The outer shell 401 and the step enclose the compressor cabin 403.

[0070] Optionally, the high temperature stage compressor 102 and the low temperature stage compressor 202 are both located in the same compressor cabin 403. This can reduce the space of the inner tank 402 occupied by the compressor cabin 403 and increase the storage capacity of the inner tank 402.

When the area of ​​reinforcing rib 80 accounts for more than 30% of the area of ​​compressor base plate 60, the first placement position 809 and the second placement position 810 are occupied, so that compressor base plate 60 loses effective loading space.
