Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration technology, and in particular to an energy-saving and high-efficiency refrigeration machine. Background Technology
[0002] Energy-efficient and high-performance refrigeration units are refrigeration devices that achieve high efficiency and significantly reduce energy consumption during operation through optimized design and the use of advanced technologies and materials. These units are widely used in industrial, commercial, and residential applications, especially in environments with high energy efficiency requirements.
[0003] Most existing refrigeration machines work by injecting refrigerant into the compressor, which then forces the high-pressure liquid refrigerant through an expansion valve or throttling device into the evaporator. The expansion valve restricts the flow of liquid, causing the pressure of the liquid refrigerant to drop rapidly. This process also causes the refrigerant temperature to drop significantly, becoming a low-temperature, low-pressure liquid refrigerant, which is then transported to the inside of the refrigeration machine through copper pipes to cool the interior. However, traditional copper pipe designs are mostly exposed, causing cold air to form water droplets on the copper pipe surface during operation, resulting in cold air leakage and increasing the compressor's energy consumption. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an energy-saving and high-efficiency refrigeration machine.
[0005] This utility model is achieved by the following technical solution: an energy-saving and high-efficiency refrigeration machine, including a refrigeration machine shell, an energy-saving component inside the refrigeration machine shell, and a heat-insulating component inside the refrigeration machine shell.
[0006] The energy-saving component includes a refrigeration unit, which is fixedly connected to the inner wall of the refrigeration unit housing. A transmission copper pipe is connected to the output end of the refrigeration unit. Energy-saving heat insulation cotton is disposed in contact with the surface of the transmission copper pipe. A limiting shell is disposed in contact with the surface of the energy-saving heat insulation cotton away from the transmission copper pipe. A rotating rod is rotatably connected to the inner wall of the limiting shell. A second limiting shell is rotatably connected to the outer wall of the rotating rod. The outer wall of the second limiting shell is in contact with the outer wall of the energy-saving heat insulation cotton. A limiting connection groove is formed on the outer wall of the limiting shell. A connecting block is slidably connected to the inner wall of the limiting connection groove.
[0007] As a further improvement to the above solution, two limiting connection slots are provided, and the two limiting connection slots are symmetrically arranged with the transmission copper pipe as the center. The symmetrically provided limiting connection slots are provided on the second surface of the limiting shell.
[0008] As a further improvement to the above solution, two energy-saving heat insulation cottons are provided, and the two energy-saving heat insulation cottons are symmetrically arranged with the transmission copper pipe as the center. Several limiting shells are provided, several rotating rods are provided, several limiting shells are provided, and several connecting blocks are provided.
[0009] Through the above technical solution, by installing energy-saving heat insulation cotton on the surface of the transmission copper pipe, and then driving the rotating rod through the limiting shell, the rotating rod drives the second limiting shell, so that the limiting shell and the second limiting shell rotate around the rotating rod, thereby making the limiting shell and the second limiting shell adhere to the surface of the energy-saving heat insulation cotton.
[0010] As a further improvement to the above solution, the insulation component includes a refrigeration pipe, with one end of the transmission copper pipe away from the refrigeration unit connected to the inside of the refrigeration pipe, and a refrigeration pipe fixing block fixedly connected to the outer wall of the refrigeration pipe, the outer wall of the refrigeration pipe fixing block being fixedly connected to the inner wall of the refrigeration unit's outer casing.
[0011] As a further improvement to the above solution, a plurality of refrigeration pipe fixing blocks are provided, and the plurality of refrigeration pipe fixing blocks are evenly arranged on the surface of the refrigeration pipe.
[0012] As a further improvement to the above solution, an installation limiting groove is provided on the inner wall of the refrigeration unit housing, a heat transfer plate is fixedly connected to the inner wall of the refrigeration unit housing, and a refrigeration unit door is hinged to the outer wall of the refrigeration unit housing.
[0013] As a further improvement to the above solution, a buffer sleeve is fixedly connected to the outer wall of the refrigeration unit door, and the end of the buffer sleeve away from the refrigeration unit door contacts the surface of the refrigeration unit outer shell. An aluminum foil insulation board is fixedly connected to the inner wall of the refrigeration unit door.
[0014] Through the above technical solution, the transmission copper pipe is transmitted through the refrigeration pipe inside the refrigeration unit casing. Then, the refrigeration pipe transmits cold air through the transmission temperature guide plate to the inside of the refrigeration unit casing. The shelf is then placed inside the installation limiting groove, which is designed with an inclination to effectively prevent the shelf inside the installation limiting groove from sliding outward when the refrigeration unit door is opened.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention involves installing energy-saving insulation cotton on the surface of a transmission copper pipe. A limiting outer shell drives a rotating rod, which in turn rotates a second limiting outer shell around the rotating rod. This causes the second and third limiting outer shells to adhere to the surface of the energy-saving insulation cotton, thus ensuring its contact with the transmission copper pipe surface. A connecting block is then installed inside the limiting connecting groove, connecting the second and third limiting outer shells and preventing them from detaching from the energy-saving insulation cotton surface. The transmission copper pipe transfers heat during operation, especially during condensation and evaporation, where the surface temperature difference is significant. The energy-saving insulation cotton effectively reduces heat transfer from the pipe surface to the external environment, preventing excessive heat loss from components such as the condenser and evaporator. This improves the energy efficiency of the refrigeration unit, allowing the refrigeration system to operate more efficiently at the same power output and saving energy.
[0017] This invention uses a copper transmission pipe to transfer cold air into the refrigerator casing via a cooling pipe. The cold air is then transferred through the cooling pipe and a temperature-conducting plate into the refrigerator casing. A shelf is then placed inside a mounting groove with an inclined design to effectively prevent the shelf from sliding outwards when the refrigerator door is opened. Furthermore, a buffer sleeve is fixedly connected to the surface of the refrigerator door, providing effective cushioning and sealing when the door is opened and closed, preventing gas leakage from inside the refrigerator casing.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0029] Example:
[0030] Please combine Figure 1-8 This embodiment provides an energy-saving and high-efficiency refrigeration unit, including a refrigeration unit housing 1, an energy-saving component 2 disposed inside the refrigeration unit housing 1, and a heat-insulating component 3 disposed inside the refrigeration unit housing 1.
[0031] The energy-saving component 2 includes a refrigerator 201, which is fixedly connected to the inner wall of the refrigerator housing 1. A transmission copper pipe 202 is connected to the output end of the refrigerator 201. An energy-saving heat insulation cotton 203 is provided in contact with the surface of the transmission copper pipe 202. A limiting shell 204 is provided in contact with the surface of the energy-saving heat insulation cotton 203 away from the transmission copper pipe 202. A rotating rod 205 is rotatably connected to the inner wall of the limiting shell 204. A second limiting shell 206 is rotatably connected to the outer wall of the rotating rod 205. The outer wall of the second limiting shell 206 is in contact with the outer wall of the energy-saving heat insulation cotton 203. A limiting connection groove 207 is opened on the outer wall of the limiting shell 204. A connecting block 208 is slidably connected to the inner wall of the limiting connection groove 207.
[0032] Two limiting connection slots 207 are provided, and the two limiting connection slots 207 are symmetrically arranged with the transmission copper pipe 202 as the center. The symmetrically provided limiting connection slots 207 are provided on the surface of the limiting outer shell 206.
[0033] There are two energy-saving heat insulation cotton 203s, which are symmetrically arranged with the transmission copper pipe 202 as the center. There are several limiting shells 204, several rotating rods 205, several limiting shells 206, and several connecting blocks 208.
[0034] The insulation component 3 includes a refrigeration pipe 301. One end of the transmission copper pipe 202 away from the refrigeration unit 201 is connected to the inside of the refrigeration pipe 301. A refrigeration pipe fixing block 302 is fixedly connected to the outer wall of the refrigeration pipe 301. The outer wall of the refrigeration pipe fixing block 302 is fixedly connected to the inner wall of the refrigeration unit housing 1.
[0035] Several cooling pipe fixing blocks 302 are provided, and the several cooling pipe fixing blocks 302 are evenly distributed on the surface of the cooling pipe 301.
[0036] The inner wall of the refrigeration unit housing 1 is provided with an installation limiting groove 303, a transmission temperature guiding plate 304 is fixedly connected to the inner wall of the refrigeration unit housing 1, and a refrigeration unit door 305 is hinged to the outer wall of the refrigeration unit housing 1.
[0037] A buffer sleeve 306 is fixedly connected to the outer wall of the refrigeration unit door 305. The end of the buffer sleeve 306 away from the refrigeration unit door 305 contacts the surface of the refrigeration unit outer casing 1. An aluminum foil insulation board 307 is fixedly connected to the inner wall of the refrigeration unit door 305.
[0038] The implementation principle of an energy-saving and high-efficiency refrigeration machine in this application embodiment is as follows: Energy-saving insulation cotton 203 is installed on the surface of the transmission copper pipe 202. Then, the limiting shell 204 drives the rotating rod 205, which in turn drives the limiting shell 206. This causes the limiting shells 204 and 206 to rotate around the rotating rod 205, thereby bringing them into contact with the surface of the energy-saving insulation cotton 203, which in turn adheres to the surface of the transmission copper pipe 202. Then, the connecting block... 208 is installed inside the limiting connection groove 207, thereby connecting the limiting outer shell 206 and the limiting outer shell 204 through the connecting block 208, preventing the limiting outer shell 204 and the limiting outer shell 206 from detaching from the surface of the energy-saving insulation cotton 203. The copper pipe 202 will transfer a certain amount of heat during operation, especially during the condensation and evaporation processes, when the surface temperature of the copper pipe is large. Therefore, the energy-saving insulation cotton 203 can effectively reduce the heat transfer from the pipe surface to the external environment, avoiding excessive heat loss from components such as the condenser and evaporator. This improves the energy efficiency of the refrigeration unit, allowing the refrigeration system to work more effectively at the same power level and saving energy. The cold air is then transmitted through the copper pipe 202 and the refrigeration pipe 301 into the refrigeration unit casing 1. The cold air is then transferred through the refrigeration pipe 301 and the heat-conducting plate 304 into the refrigeration unit casing 1. The shelf is then placed inside the mounting limiting groove 303, which is designed to be inclined to prevent the shelf from sliding outwards when the refrigeration unit door 305 is opened. A buffer sleeve 306 is fixedly connected to the surface of the refrigeration unit door 305, effectively buffering and sealing the door when it is opened and closed, preventing gas leakage from the refrigeration unit casing 1. Finally, the aluminum foil insulation plate 307 inside the refrigeration unit door 305, with its high reflectivity, effectively reflects heat. By using aluminum foil to create insulation panels, heat transfer can be reduced, whether keeping the environment cool in high temperatures or warm in low temperatures. This insulating property of aluminum foil helps reduce energy waste and improve system efficiency.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
