Description

Technical Field

[0001] The present invention relates to a refrigeration device, and particularly to a compact refrigeration device applicable to a small space.

Background Art

[0002] Refrigeration devices (air conditioners) have become an indispensable part of modern life. They can effectively adjust the indoor temperature and humidity, providing a comfortable living and working environment, whether in hot summers or high-humidity environments. In residential, office, commercial facilities or vehicles, the presence of refrigeration devices has significantly improved people's quality of life. Especially in particularly hot regions, refrigeration devices are important facilities for maintaining physical and mental health. Furthermore, since many industrial or medical environments rely on refrigeration systems to operate equipment normally or maintain predetermined temperature conditions, refrigeration devices have become one of the essential electrical appliances in modern society.

[0003] As shown in FIG. 1, a general refrigeration device 1 mainly consists of a compressor 11, a condenser 12, an expansion valve 13 (or throttle device), an evaporator 14, and a refrigerant (not shown in the figure). Its operating principle is to absorb or release heat through the transition process of the refrigerant. First, the compressor 11 compresses the low-pressure gaseous refrigerant into a high-pressure and high-temperature gaseous state and sends it to the condenser 12 for heat dissipation, thereby converting the refrigerant into a high-pressure liquid. Subsequently, the liquid refrigerant is depressurized through the expansion valve 13 and quickly evaporates after entering the evaporator 14 to absorb the indoor heat, thereby lowering the air temperature. Finally, the gaseous refrigerant returns to the compressor 11 again for circulation. By continuously performing such a circulation operation, the indoor coolness is maintained.

[0004] As can be seen from the above, the applications and technologies of air conditioning systems are already widespread and mature. However, with changes in lifestyles in recent years, the number of people living alone or with nuclear families is gradually increasing, and homes are also becoming more compact. Furthermore, with the growing camping boom, more and more people are converting their cars into camper vans. However, whether compact homes or camper vans, most have an area of less than 10 tsubo (approx. 33 m2), and most camper vans in particular are less than 10 tsubo (approx. 9 m2). Summary of the Invention [Problem to be solved by the invention]

[0005] For these reasons, the size of conventional air conditioners, especially for camper vans, is not suitable for small spaces. In other words, the volume of conventional air conditioners is too large to be installed in small spaces. Therefore, it is a very important task to provide a compact air conditioner that can be used in small spaces.

[0006] The object of the present invention is to provide a compact cooling device that can be used in small spaces. [Means for solving the problem]

[0007] To achieve the above objectives, the present invention provides a cooling device comprising a compressor, a condenser, an expansion valve, and an evaporator. The compressor delivers high-pressure gaseous refrigerant. The condenser includes a heat-rejecting refrigerant pipe, through which the high-pressure gaseous refrigerant is transferred to dissipate heat and become high-pressure liquid refrigerant. The expansion valve is connected to the condenser's heat-rejecting refrigerant pipe, reducing the pressure of the high-pressure liquid refrigerant to low-pressure refrigerant. The evaporator includes at least a cooling refrigerant pipe, through which the low-pressure refrigerant delivered by the expansion valve is transferred. The volume of the refrigerant contained in the cooling refrigerant pipe is 300 cm. 3 From 1000cm 3 is.

[0008] In one embodiment, the cooling device of the present invention further includes a high-pressure refrigerant pipe. One end of the high-pressure refrigerant pipe is connected to the compressor, and the other end is connected to the heat-radiating refrigerant pipe, so that high-pressure gaseous refrigerant is sent into the heat-radiating refrigerant pipe.

[0009] In one embodiment, the cooling device of the present invention further includes a first throttle pipe. One end of the first throttle pipe is connected to the heat-radiating refrigerant pipe of the condenser, and the other end is connected to the expansion valve, so that high-pressure gaseous refrigerant is sent into the expansion valve.

[0010] In one embodiment, the accommodation volume of the heat-radiating refrigerant pipe is 1.2 to 1.5 times that of the cooling refrigerant pipe.

[0011] In one embodiment, the pipe diameter of the cooling refrigerant pipe is 1 cm to 2.5 cm, and the pipe diameter of the heat-radiating refrigerant pipe is 0.5 cm to 1.5 cm.

[0012] Also, to achieve the above object, the present invention provides a cooling device, which includes a compressor, a condenser, an expansion valve, and an evaporator. The compressor sends out high-pressure gaseous refrigerant. The condenser includes a heat-radiating refrigerant pipe, and sends the high-pressure gaseous refrigerant sent out from the compressor into the heat-radiating refrigerant pipe to dissipate heat, so as to become high-pressure liquid refrigerant. The expansion valve is connected to the heat-radiating refrigerant pipe of the condenser and reduces the pressure of the high-pressure liquid refrigerant to low-pressure refrigerant. The evaporator includes a first cooling refrigerant pipe and a second cooling refrigerant pipe, and the expansion valve sends the low-pressure refrigerant into the first cooling refrigerant pipe and the second cooling refrigerant pipe respectively.

[0013] In one embodiment, the evaporator further includes a refrigerant inlet pipe and a refrigerant outlet pipe. One end of the first cooling refrigerant pipe and one end of the second cooling refrigerant pipe are respectively connected to the refrigerant inlet pipe, and the other end of the first cooling refrigerant pipe and the other end of the second cooling refrigerant pipe are respectively connected to the refrigerant outlet pipe.

[0014] In one embodiment, the cooling device of the present invention further includes a high-pressure refrigerant pipe. One end of the high-pressure refrigerant pipe is connected to the compressor, and the other end is connected to the heat-radiating refrigerant pipe, so that high-pressure gaseous refrigerant is sent into the heat-radiating refrigerant pipe.

[0015] In one embodiment, the cooling device of the present invention further includes a first throttle pipe, one end of which is connected to the heat-dissipating refrigerant pipe of the condenser, and the other end of which is connected to the expansion valve, so that high-pressure liquid refrigerant is delivered to the expansion valve.

[0016] In one embodiment, the volume of the refrigerant contained in the first cooling refrigerant pipe or the second cooling refrigerant pipe is 300 cm 3 From 500cm 3 is.

[0017] In one embodiment, the accommodating volume of the heat dissipating refrigerant pipe is 1.2 to 1.5 times the combined accommodating volume of the first cooling refrigerant pipe and the second cooling refrigerant pipe.

[0018] In one embodiment, the diameter of the first or second cooling refrigerant pipe is 1 cm to 2.5 cm, and the diameter of the heat dissipating refrigerant pipe is 0.5 cm to 1.5 cm.

[0019] To summarize the above, the volume of the refrigerant contained in the first or second cooling refrigerant pipe of the cooling device of this invention is 300 cm 3 From 500cm 3 The diameter of the first or second cooling refrigerant pipe is 1cm to 2.5cm. Therefore, the length of the first or second cooling refrigerant pipe of this invention is limited to a certain length and is installed in a reciprocating manner, so the size of the evaporator of this invention can be small. Furthermore, the volume of the heat dissipation refrigerant pipe of this invention is 1.2 to 1.5 times the combined volume of the first and second cooling refrigerant pipes, so the condenser of this invention is correspondingly small. Because both the condenser and evaporator of this invention are small, the entire air conditioning unit can be made small, making it suitable for installation and use in small spaces.

[0020] Furthermore, since the evaporator of the air conditioning device of this invention includes a first cooling refrigerant pipe and a second cooling refrigerant pipe, the low-pressure refrigerant can be quickly introduced and discharged from the two cooling refrigerant pipes, and heat exchange can be carried out quickly, resulting in an immediate cooling effect. [Effects of the Invention]

[0021] Since the cooling device of the present invention can be made smaller, it is suitable for installation and use in a small space.

Embodiments for Carrying Out the Invention

[0023] The following specifically describes the present invention with reference to the drawings.

[0024] As shown in FIG. 2, the cooling device 2 of the present invention includes a compressor 21, a condenser 22, an expansion valve 23, and an evaporator 24.

[0025] The compressor 21 sends out high-pressure gaseous refrigerant through the high-pressure refrigerant pipe 211. The condenser 22 includes a heat-radiating refrigerant pipe 221 and a plurality of heat-radiating fins 222. The high-pressure gaseous refrigerant sent out from the compressor 21 is sent into the heat-radiating refrigerant pipe 221 and is radiated by these heat-radiating fins 222 to become high-pressure liquid refrigerant. The expansion valve 23 is connected to the heat-radiating refrigerant pipe 221 of the condenser 22 by the first throttle pipe 231 to reduce the pressure of the high-pressure liquid refrigerant to low-pressure refrigerant.

[0026] Furthermore, please refer to FIGS. 2 and 3. The evaporator 24 includes a first cooling refrigerant pipe 241, a second cooling refrigerant pipe 242, and a plurality of heat exchange fins 243. The low-pressure refrigerant sent out by the expansion valve 23 flows into the second throttle pipe 232 and is respectively sent into the first cooling refrigerant pipe 241 and the second cooling refrigerant pipe 242 by the refrigerant introduction pipe 244. It should be noted that in another embodiment, the first cooling refrigerant pipe 241 and the second cooling refrigerant pipe 242 can communicate with each other so as to become a single cooling refrigerant pipe. In this case, the refrigerant introduction pipe 244 is directly connected to one end of the cooling refrigerant pipe (not shown in the figure).

[0027] Furthermore, as shown in FIGS. 2 and 3, the low-pressure refrigerant flows into the second throttle pipe 232, and after being respectively fed into the first cooling refrigerant pipe 241 and the second cooling refrigerant pipe 242 by the refrigerant introduction pipe 244, the refrigerant after heat exchange is sent out through the refrigerant outlet pipe 245, and then is fed into the compressor 21 through the low-pressure refrigerant pipe 212. It should be noted that in another embodiment, the first cooling refrigerant pipe 241 and the second cooling refrigerant pipe 242 can communicate with each other so as to form a single cooling refrigerant pipe. In this case, the refrigerant outlet pipe 245 is directly connected to the other end of the cooling refrigerant pipe (not shown in the figure).

[0028] As described above, the evaporator 24 of the present invention includes the first cooling refrigerant pipe 241 and the second cooling refrigerant pipe 242, but in another embodiment, it is also possible to configure it using a single cooling refrigerant pipe. In the case of two cooling refrigerant pipes or a single cooling refrigerant pipe, the volume of the refrigerant accommodated in the single cooling refrigerant pipe can be limited to 300 cm 3 to 1000 cm 3 ; when using two cooling refrigerant pipes, the volume of the refrigerant accommodated in any one of the cooling refrigerant pipes can be limited to 300 cm 3 to 500 cm 3 .

[0029] Furthermore, in order to accelerate the heat dissipation rate, the accommodation volume of the heat dissipation refrigerant pipe 221 of the condenser 22 of the present invention is 1.2 times to 1.5 times the total accommodation volume of the cooling refrigerant pipes 241 and 242. And the pipe diameters of the cooling refrigerant pipes 241 and 242 are 1 cm to 2.5 cm, and the pipe diameter of the heat dissipation refrigerant pipe 221 is 0.5 cm to 1.5 cm.

[0030] It should be noted that as shown in FIG. 4, in actual applications, when the low-pressure refrigerant pipe 212 and the second throttle pipe 232 of the present invention are extended and lengthened, the cooling device 2 of the present invention can be in a form having an indoor unit and an outdoor unit. That is, the condenser 22 and the compressor 21 can be placed outdoors, and the evaporator 24 can be placed indoors.

[0031] To sum up, the volume of the refrigerant contained in the first cooling refrigerant pipe 241 or the second cooling refrigerant pipe 242 of the cooling device of the present invention is 300 cm 3 to 500 cm 3 , and the pipe diameters of the first and second cooling refrigerant pipes 241 and 242 are 1 cm to 2.5 cm. Therefore, the length of the first cooling refrigerant pipe 241 or the second cooling refrigerant pipe 242 of the present invention is limited to a certain length and is installed to reciprocate, so the size of the evaporator of the present invention can be reduced. In addition, since the accommodation volume of the heat dissipation refrigerant pipe 221 of the present invention is 1.2 times to 1.5 times the total accommodation volume of the first cooling refrigerant pipe 241 and the second cooling refrigerant pipe 242, the condenser of the present invention is relatively small. Since both the condenser 22 and the evaporator 24 of the present invention are small, the entire cooling device can be made small, which is suitable for installation and use in a small space.

Industrial Applicability

[0032] Since the evaporator 24 of the cooling device 2 of the present invention includes the first cooling refrigerant pipe 241 and the second cooling refrigerant pipe 242, the low-pressure refrigerant can be quickly introduced or led out from the two cooling refrigerant pipes, and heat exchange is performed quickly, so the cooling effect is immediately achieved.
