Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an integrated internal circulation refrigeration and heat dissipation air conditioner. Background Art

[0002] An air conditioner, i.e., an air regulator, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air environment in a building or structure. An air conditioner generally includes a cold source / heat source device, a cold and hot medium distribution system, an end device, and several other auxiliary devices. It mainly includes: a refrigeration host, a water pump, a fan, and a pipeline system. The end device is responsible for using the cold and heat transferred to specifically process the air state so that the air parameters of the target environment meet certain requirements.

[0003] When the equipment is running, it will generate relatively high heat. For example, there are some cabinets in a computer room, and switches, routers, bridges, etc. are placed inside the cabinets. Therefore, the temperature inside the cabinets will rise due to the operation of the equipment. In a high-temperature environment, it is not only easy to affect the normal operation of the equipment but also its service life.

[0004] Therefore, fans are usually installed inside the cabinets to assist in heat dissipation. However, the heat dissipation capacity of the fans is limited. Especially in a computer room with densely distributed cabinets, the high temperature of the equipment will cause the temperature of the computer room to rise, resulting in the air blown by the fans being hot air, making it difficult to play a role in cooling. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an integrated internal circulation refrigeration and heat dissipation air conditioner.

[0006] The technical solution of the utility model is: an integrated internal circulation refrigeration and heat dissipation air conditioner, including: a placement cabinet in which several vertically distributed heat-generating devices are placed; a refrigeration air conditioner horizontally placed at the bottom of the placement cabinet, the refrigeration air conditioner including: a box body on which there are a heat absorption port facing the outside of the placement cabinet, a heat discharge port facing the outside of the placement cabinet, a heat inlet port facing the inside of the placement cabinet, and a refrigeration port facing the inside of the placement cabinet; a condensation component, an evaporation component, and a compressor component arranged inside the box body; wherein, the air extracted from the heat absorption port can be discharged from the heat discharge port, and the air entering from the heat inlet port can be discharged from the refrigeration port.

[0007] Further, the condensation component includes: a condenser fixed at the heat absorption port; a partition plate arranged inside the box body for separating the heat inlet port and the heat discharge port; a mounting plate arranged inside the box body near the heat absorption port; an air extraction fan mounted on the mounting plate, and the air extraction fan can extract air from the heat absorption port and discharge it from the heat discharge port.

[0008] Further, the evaporation component includes: an evaporator disposed inside the box body; a mounting rack fixed inside the box body and close to the evaporator; and an exhaust fan disposed on the mounting rack and close to the refrigerant outlet of the refrigeration port, and the exhaust fan can discharge the cold air around the evaporator from the refrigeration port into the storage cabinet.

[0009] Further, the compressor component includes: a compressor main body disposed inside the box body; a gas transmission pipe fixedly connected to the gas outlet of the compressor main body, and the other end of the gas transmission pipe is connected to the condensation component; an air inlet pipe fixedly connected to the gas inlet of the compressor main body, and the other end of the air inlet pipe is connected to the evaporation component; and a liquid delivery pipe for connecting the evaporation component and the condensation component.

[0010] Further, an expansion valve is provided on the liquid delivery pipe.

[0011] Further, the bottom of the storage cabinet is open, and a fixing rack for supporting the refrigeration air conditioner is provided at the bottom of the storage cabinet.

[0012] The beneficial technical effects of the present utility model are as follows: When the refrigerant at normal temperature and high pressure passes through the evaporation component, an evaporation reaction will occur, causing the refrigerant to absorb heat and turn into a gaseous state. Since the heat in the surrounding environment is absorbed, the temperature around the evaporation component will be lower than the normal temperature environment. Then, the cold air can be discharged through the refrigeration port. Because the refrigeration port faces the storage cabinet, the inside of the storage cabinet can be cooled. The cold air is blown by the fan and has a certain fluidity, so it can drive the air inside the storage cabinet to flow. Also, because the heat generated by the heat-generating equipment does not disappear, and when the air is flowing, the air with heat will enter the inside of the refrigeration air conditioner through the heat inlet and then pass through the evaporation component again for heat absorption and cooling treatment, so as to achieve internal circulation, effectively cool the heat-generating equipment inside the storage cabinet, maintain a constant temperature state, and will not be affected by high temperature during normal operation, improving the operation stability. And by adopting the internal circulation method, it can effectively avoid contact with the outside air, thereby reducing the impact of dust on the equipment. Moreover, the refrigeration air conditioner as a whole is an integrated air conditioner, without the need for pipeline settings for the indoor and outdoor units, which is more convenient for installation and saves floor space.

[0019] In order to more clearly understand the technical means of the present utility model and be able to implement it according to the content of the specification, the following further describes in detail the specific implementation manners of the present utility model in combination with the drawings and embodiments. The following embodiments are used to illustrate the present utility model but not to limit the scope of the present utility model.

[0020] Refer to the attached Figures 1-4 As shown in the figure, the integrated internal circulation refrigeration and heat dissipation air conditioner of Embodiment 1 includes: a placing cabinet 1, and a plurality of vertically distributed heat generating equipment 11 are placed in the placing cabinet 1.

[0021] The heat generating equipment 11 is equipment such as routers and switches that are widely distributed in the placing cabinet 1 and will generate heat during operation.

[0022] The refrigeration air conditioner is horizontally placed at the bottom of the placing cabinet 1. The refrigeration air conditioner includes: a box body 2, and the box body 2 is provided with a heat absorption port 21 facing the outside of the placing cabinet 1, a heat discharge port 22 facing the outside of the placing cabinet 1, a heat inlet 23 facing the inside of the placing cabinet 1, and a refrigeration port 24 facing the inside of the placing cabinet 1; a condensation component, an evaporation component, and a compressor component arranged inside the box body 2; wherein, the air extracted from the heat absorption port 21 can be discharged from the heat discharge port 22, and the air entering from the heat inlet 23 can be discharged from the refrigeration port 24.

[0023] When the refrigeration air conditioner is working, it can extract the outside air by using the heat absorption port 21, so that the outside air blows towards the condensation component, thereby changing the refrigerant from a high-temperature and high-pressure gas to a normal-temperature and high-pressure liquid. Since the air has a certain amount of heat after heat exchange, it can be discharged to the outside of the placing cabinet 1 through the heat discharge port 22, achieving the function of external circulation, so that the heat generated by the air conditioner will not affect the ambient temperature inside the placing cabinet 1.

[0024] When the refrigerant at normal temperature and high pressure passes through the evaporation component, an evaporation reaction will occur, causing the refrigerant to absorb heat and turn into a gas. Since the heat in the surrounding environment is absorbed, the temperature around the evaporation component will be lower than the normal temperature environment. Then, the cold air can be discharged through the refrigeration port 24. Because the refrigeration port 24 faces the storage cabinet 1, the inside of the storage cabinet 1 can be cooled. The cold air is blown by a fan and has a certain fluidity, so it can drive the air inside the storage cabinet 1 to flow. Also, because the heat generated by the heat-producing device 11 does not disappear, and when the air is circulating, the air with heat will enter the inside of the refrigeration air conditioner through the heat inlet 23 and be re-cooled by passing through the evaporation component, thus achieving an internal circulation. This enables the heat-producing device 11 inside the storage cabinet 1 to be effectively cooled and maintain a constant temperature state, without being affected by high temperature and ensuring normal operation, improving the stability of operation. Moreover, by adopting the internal circulation method, it can effectively avoid contact with the outside air, thereby reducing the impact of dust on the equipment. And the refrigeration air conditioner as a whole is an integrated air conditioner, without the need for pipeline settings for the indoor and outdoor units, which is more convenient for installation and saves floor space.

[0025] Further, the condensation component includes: a condenser 3 fixed at the heat absorption port 21; a partition plate 31 provided inside the box body 2 for separating the heat inlet 23 and the heat discharge port 22; a mounting plate 32 provided inside the box body 2 near the heat absorption port 21; and an air extraction fan 33 mounted on the mounting plate 32, which can extract air from the heat absorption port 21 and discharge it from the heat discharge port 22.

[0026] The air extraction fan 33 can extract the air outside the box body 2 through the heat absorption port 21, enabling the outside air to exchange heat with the refrigerant passing through the condenser 3, so that the high-temperature and high-pressure gaseous refrigerant becomes a normal-temperature and high-pressure liquid refrigerant. The hot air after heat exchange will be discharged through the heat discharge port 22, preventing the hot air from entering the inside of the storage cabinet 1 and avoiding the increase in the temperature inside the storage cabinet 1 due to the hot air.

[0027] The partition plate 31 can separate the air entering the refrigeration air conditioner through the heat inlet 23 from the air entering through the heat absorption port 21, enabling the hot air to achieve separate internal and external circulations without interference.

[0028] Further, the evaporation component includes: an evaporator 4 provided inside the box body 2; a mounting frame 41 fixed inside the box body 2 and close to the evaporator 4; and an exhaust fan 42 provided on the mounting frame 41 and close to the refrigeration port 24, which can discharge the cold air around the evaporator 4 from the refrigeration port 24 into the storage cabinet 1.

[0029] When the refrigerant passes through the evaporator 4, it absorbs heat and evaporates, turning the surrounding air into cold air. Then, the cold air can be discharged through the exhaust fan 42 through the refrigeration port 24, so that the cold air is blown into the inside of the storage cabinet 1.

[0030] Furthermore, the compressor assembly includes: a compressor main body 5 disposed inside the cabinet 2; an air delivery pipe 51 fixedly connected to the gas output port of the compressor main body 5, with the other end of the air delivery pipe 51 connected to the condensation assembly; an air inlet pipe 53 fixedly connected to the gas input port of the compressor main body 5, with the other end of the air inlet pipe 53 connected to the evaporation assembly; and a liquid delivery pipe 52 for connecting the evaporation assembly and the condensation assembly.

[0031] When the compressor main body 5 is working, it can change the low-pressure and low-temperature gaseous refrigerant into a high-temperature and high-pressure refrigerant. Then, the high-temperature and high-pressure refrigerant will enter the condensation assembly through the air delivery pipe 51. After passing through the condensation assembly and becoming a normal-temperature and high-pressure liquid, it will enter the liquid delivery pipe 52, and then enter the evaporation assembly through the liquid delivery pipe 52. After becoming a low-pressure gas through the evaporation assembly, it will finally enter the inside of the compressor main body 5 again through the air inlet pipe 53 to become a high-temperature and high-pressure gas, forming a cycle.

[0032] Furthermore, an expansion valve 54 is provided on the liquid delivery pipe 52. The expansion valve 54 is used to adjust the refrigerant flow rate on the liquid delivery pipe 52, turning the normal-temperature and high-pressure gas into a normal-temperature and low-pressure gas-liquid mixture.

[0033] Furthermore, the bottom of the placement cabinet 1 is open, and a fixing frame 12 for supporting the refrigeration air conditioner is provided at the bottom of the placement cabinet 1.

[0034] The open setting can distinguish the internal and external air circulation of the refrigeration air conditioner, and the fixing frame 12 can support the refrigeration air conditioner.

[0035] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
