Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
An air conditioning system 1 according to an embodiment of the first aspect of the present invention is described below with reference to the drawings.
As shown in fig. 1 to 14, an air conditioning system 1 according to an embodiment of the present invention includes: the air conditioner comprises a compressor 10, an outdoor heat exchanger 20, a throttling element 30, an indoor heat exchanger 40, an electronic control box 50 and a refrigerant heat dissipation module 60.
Specifically, the compressor 10, the outdoor heat exchanger 20, the throttling element 30, and the indoor heat exchanger 40 are sequentially connected by refrigerant pipes to form a closed circuit. The electric control box 50 comprises a closed cavity and an electric control component arranged in the cavity, and the electric control component is electrically connected with the compressor 10. The refrigerant heat dissipation module 60 is used for cooling the electronic control component, and the refrigerant heat dissipation module 60 is connected in series between the compressor 10 and the indoor heat exchanger 40.
Therefore, the electric control component is radiated by using the outlet refrigerant of the indoor heat exchanger 40, so that the cooling effect is good; and the electronic control component is arranged in the closed space, so that the air in the closed space is limited, the cooling effect is better, more condensed water cannot be generated at the accessory of the electronic control component, and the reliability of the electronic control component is ensured.

It is to be understood that the air conditioning system 1 may be applied to a single chiller, as shown in fig. 1; further, as shown in fig. 2, the air conditioning system 1 may also be applied to a cooling and heating machine, for example, the air conditioning system 1 further includes: the reversing device 70 is switchable between a first state and a second state, the reversing device 70 has a first connection 71, a second connection 72, a third connection 73, and a fourth connection 74, for example, the reversing device 70 is a four-way valve, and the four-way valve is electrically connected to the electronic control component. The first port 71 and the third port 73 are respectively communicated with the compressor 10, for example, the compressor 10 has an exhaust port and a suction port, the suction port is formed on the accumulator 11 of the compressor 10, the first port 71 is communicated with the exhaust port, and the third port 73 is communicated with the suction port. The outdoor heat exchanger 20 communicates with the second port 72, and the indoor heat exchanger 40 communicates with the fourth port 74. Here, the refrigerant heat-dissipating module 60 is connected in series between the accumulator 11 and the third port 73 of the compressor 10.
When the reversing device 70 is in the first state, the first port 71 is communicated with the second port 72, and the third port 73 is communicated with the fourth port 74, so that the refrigerant discharged from the compressor 10 enters the four-way valve, the four-way valve is in a refrigeration condition, the refrigerant enters the outdoor heat exchanger 20 through the four-way valve to be condensed, and the temperature of the refrigerant is reduced. Next, the refrigerant with the reduced temperature enters the throttling element 30, and enters the indoor heat exchanger 40 after being throttled and cooled by the throttling element 30. The low-temperature refrigerant enters the indoor heat exchanger 40 to evaporate and absorb heat, and the indoor heat exchanger 40 cools the indoor air to complete the refrigeration function. The refrigerant coming out of the indoor heat exchanger 40 passes through the four-way valve and then enters the refrigerant heat dissipation module 60, the refrigerant with lower temperature in the refrigerant heat dissipation module 60 takes away the heat productivity of the electric control component to complete the cooling of the electric control component, finally the refrigerant returns to the compressor 10 through the liquid storage device 11 to complete the compression process in the compressor 10, and the compressed refrigerant is discharged from the exhaust port of the compressor 10 to complete a cycle of the refrigeration process.
When the reversing device 70 is in the second state, the first port 71 communicates with the fourth port 74 and the second port 72 communicates with the third port 73. In this way, the refrigerant discharged from the compressor 10 enters the four-way valve, the four-way valve is in the heating mode, and the refrigerant enters the indoor heat exchanger 40 through the four-way valve, is condensed in the indoor heat exchanger 40, and completes heating of the indoor air. The temperature of the refrigerant passing through the indoor heat exchanger 40 is lowered, and the refrigerant having the lowered temperature enters the throttling element 30, is throttled by the throttling element 30, and then enters the outdoor heat exchanger 20. The refrigerant evaporates and absorbs heat in the outdoor heat exchanger 20, the refrigerant coming out of the outdoor heat exchanger 20 passes through the four-way valve and then enters the refrigerant heat dissipation module 60, the refrigerant with lower temperature in the refrigerant heat dissipation module 60 takes away heat generated in the electronic control component to complete cooling of the electronic control component, finally returns to the compressor 10 through the liquid storage device 11, the compression process is completed in the compressor 10, the compressed refrigerant is discharged from the exhaust port of the compressor 10, and thus a cycle of the heating process is completed.
According to some embodiments of the present invention, as shown in fig. 3, the cooling medium heat dissipation module 60 includes a heat dissipation tube 61, the heat dissipation tube 61 is connected to the cooling medium tube, and the cooling medium can flow into the heat dissipation tube 61 from the cooling medium tube. For example, the heat radiating pipe 61 may be a copper pipe, so that the heat conductivity is good. The cross section of the heat dissipation pipe 61 may be circular or rectangular, and the present invention is not limited thereto.
Optionally, the heat dissipation pipe 61 and the refrigerant pipe may be connected by a heat conduction member, and the heat conduction member is an aluminum member, a copper member, or a semiconductor refrigeration sheet.
Alternatively, the radiating pipe 61 may be formed of a portion of the refrigerant pipe, so that the structure is simple and the assembly is simplified.
The utility model discloses an in some embodiments, refrigerant heat dissipation module 60 can be located outside the cavity, and like this, cooling tube 61 is through cooling down to automatically controlled box 50 outside to cool down the inside automatically controlled components and parts of cavity.
Further, the cavity may be made of a heat conductive material, and the heat dissipation pipe 61 is attached to the outer surface of the cavity, so that the heat dissipation effect to the cavity may be enhanced. For example, the heat dissipation pipe 61 may be in contact with one surface of the electrical control box 50, may be in contact with multiple surfaces of the electrical control box 50, or the heat dissipation pipe 61 may be surrounded on the outer surface of the electrical control box 50.
It can be understood that, as shown in fig. 3 and 12, at least a portion of the cooling medium heat dissipation module 60 is disposed in the cavity, and the heat dissipation pipe 61 is connected to the cooling medium pipe through a through hole formed in the cavity. For example, the heat dissipation tube 61 may be partially embedded in the electrical control box 50, or may be entirely disposed inside the electrical control box 50. The heat dissipation pipe 61 penetrates into the sealed cavity to be in contact with the gas sealed in the cavity, the sealed gas is cooled, and the cooled gas cools the heated electric control component. That is to say, the heat pipe 61 penetrates the sealed electric control box 50 and then penetrates the electric control box 50, so as to take away the heat of the electric control component, reduce the temperature of the electric control component, and ensure the reliability of the electric control component and the normal use of the air conditioner in an extremely hot environment.
In some embodiments of the present invention, the heat dissipation tube 61 can be attached to the electronic control component. That is to say, the cooling tube 61 penetrates the sealed electronic control box 50 and then directly contacts the electronic control component with large heat productivity, so that the flowing low-temperature refrigerant directly cools the electronic control component, and meanwhile, the sealed air can be cooled, and then other components can be cooled, and the reliability of the electronic control component at high temperature can be ensured.
Optionally, as shown in fig. 12, a heat dissipation plate 51 may be disposed on the electronic control component, and the heat dissipation pipe 61 is attached to the heat dissipation plate 51, for example, the heat dissipation plate 51 may be an aluminum substrate, so as to increase a heat dissipation area and enhance a heat dissipation effect.
Of course, the radiating pipe 61 may be in contact with the inner wall of the cavity. For example, the electrical control box 50 has two layers, the outer layer is made of thermal insulation material, the inner layer is made of heat conductive material, and the heat dissipation pipe 61 is tightly attached to the inner layer of the electrical control box 50 after penetrating into the electrical control box 50, so as to cool the inner layer and the sealed air, and the cooled inner layer and the air cool the electrical control components which generate heat. Here, the radiating pipe 61 may be partially embedded in the inner layer, partially contacted with the air inside the electric control box 50; alternatively, the heat dissipating pipe 61 may be disposed inside the inner layer to be completely in contact with the inner layer, for example, as shown in fig. 3 and 6, the chamber includes a lower case 52 and an upper cover 53, the upper cover 53 covers the lower case 52, and the heat dissipating pipe 61 is embedded in the upper cover 53.
Wherein the radiating pipe 61 may run through one surface or multiple surfaces of the inner layer. It can be understood that the heat dissipation tube 61 should be close to the surface of the electrically controlled component where the heat generation is larger when passing through the surface of the inner layer.
Alternatively, as shown in fig. 9, the heat dissipation pipe 61 is configured in a "U" shape, for example, the heat dissipation pipe 61 penetrates into the closed electronic control box 50 and directly contacts with the electronic control component with a large heat generation amount, and the low-temperature refrigerant in the pipeline absorbs the heat of the electronic control component, so that the temperature of the electronic control component is reduced, passes through a U-shaped path, and then passes out of the electronic control box 50. The heat dissipation pipe 61 inside the electric control box 50 may have various orientations, for example, the heat dissipation pipe 61 may also have a straight line shape or a serpentine shape extending in a serpentine shape. It can be understood that, along with the increase of the length of the refrigerant pipeline inside the electronic control box 50, the more the heat of the electronic control components is taken away by the refrigerant, the better the cooling effect is, and the length and the trend of the pipeline can be set according to the actual conditions.
In some embodiments of the present invention, as shown in fig. 7-9, the cooling medium heat dissipation module 60 further includes heat dissipation fins 62, and the heat dissipation fins 62 are sleeved on the heat dissipation tube 61. That is, the cooling medium heat dissipation module 60 may be composed of the heat dissipation tube 61 and the heat dissipation fins 62, so as to increase the heat transfer area of the heat dissipation tube 61 and increase the heat transfer amount. For example, the heat dissipating pipe 61 has a "U" shape, the heat dissipating pipe 61 penetrates the heat dissipating fins 62, and the heat dissipating fins 62 may be plural, and the plural heat dissipating fins 62 are arranged along the axial direction of the heat dissipating pipe 61.
In some embodiments of the present invention, as shown in fig. 10 and 11, the cooling medium heat dissipation module 60 further includes a rotatable heat dissipation fan 63 to enhance the heat dissipation effect. For example, the heat dissipation fan 63 can be installed on the inner bottom wall of the cavity, and when the heat dissipation fan 63 rotates, the air in the electronic control box 50 can be driven to flow, so that the heat exchange among the heat dissipation pipe 61, the sealing gas and the electronic control component is enhanced, the temperature of the electronic control component is reduced more quickly, and the heat dissipation effect of the electronic control component is improved. Of course, when the cooling medium heat dissipation module 60 is disposed outside the cavity, the heat dissipation fan 63 may be disposed outside the cavity.
In some embodiments of the present invention, the cavity may be filled with an insulating heat-conducting member. For example, the cavity may be evacuated and filled with the insulating and thermally conductive member. That is, the air in the sealed electronic control box 50 can be pumped out and the material with good insulation and heat conduction performance can be refilled. Thus, after the heat dissipation pipe 61 penetrates the sealed electric control box 50, the heat dissipation pipe can contact with the insulating heat conduction material filled in the electric control box 50 and cool the electric control box, and further, the electric control components are cooled.
According to some embodiments of the utility model, refrigerant heat dissipation module 60 can also be including the temperature sensor who is used for detecting the refrigerant temperature that gets into refrigerant heat dissipation module 60, for example, temperature sensor can establish on the pipe wall of cooling tube 61, and temperature sensor and throttling element 30 are connected with automatically controlled components and parts electricity respectively. Thus, the temperature of the electric control components can be reduced by the refrigerant with proper temperature flowing out of the indoor heat exchanger 40, so that the temperature of the electric control components does not exceed the use temperature of the electric control components; according to the temperature detected by the temperature sensor, the temperature detected by the temperature sensor can be within the preset interval by adjusting the flow of the throttling element 30, namely, the temperature of the refrigerant passing through the refrigerant heat dissipation module 60 is within the preset interval by the throttling element 30 with adjustable flow, so that the heat dissipation effect of the electric control component is ensured, the normal heat dissipation of the electric control component in a high-temperature environment is ensured, and the reliability is ensured.
According to the utility model discloses air conditioning equipment of second aspect embodiment includes: according to the utility model discloses air conditioning system 1, off-premises station and indoor set of first aspect embodiment.
