Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
An air conditioning apparatus 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
An air conditioning apparatus 100 according to an embodiment of the present invention, as shown in fig. 1, includes: the outdoor heat exchanger comprises a compressor 1, an outdoor heat exchanger 2, a throttling element 3, an electric control box assembly 5 and a refrigerant heat dissipation module 6 for cooling the electric control box assembly 5.

The specific construction and operation of such components as compressors, heat exchangers, etc. are known to those of ordinary skill in the art and will not be described in detail herein.
The electric control box assembly 5 is electrically connected with the compressor 1, the electric control box assembly 5 is used for controlling the working state of the compressor 1, and the electric control box assembly 5 comprises a closed box body and components arranged in the box body. The box body is a closed box body, so that external air can be prevented from entering the box body, and particularly, external hot and humid air can be reduced from entering the box body, so that excessive condensed water in the box can be prevented from being generated, and further, the damage of components caused by water dipping is avoided. The refrigerant heat dissipation module 6 is used for cooling the electric control box assembly 5, the refrigerant heat dissipation module 6 comprises a refrigerant heat dissipation pipe 61, the refrigerant heat dissipation pipe 61 is connected in series in a refrigerant circulation system, and at least part of the refrigerant heat dissipation pipe 61 is located in the box body.
It will be appreciated that the portion of the air conditioning apparatus 100 where the compressor 1, the outdoor heat exchanger 2, and the electronic control box assembly 5 are installed is typically located outdoors, while the air conditioning apparatus 100 typically operates a cooling function on a hot day. Because of the high-speed operation of the air conditioning apparatus 100 in a high-temperature environment, the heat generation amount of the electric control box assembly 5 is large, and the ventilation property of the electric control box assembly 5 is not strong, so that the temperature of the electric control box assembly 5 is much higher than the outdoor temperature. Sometimes extremely hot high-temperature and high-humidity weather occurs, and the temperature of the electric control box assembly 5 may even exceed 60 ℃ or higher, and the weather is extremely high in consideration of not only the electric control box assembly 5 but also the refrigerant circulation system itself. Especially in the high temperature electronic control box assembly 5, local high temperature may cause softening of the pipe wall, cracking of the pipe joint due to deformation, etc.
The improvement of the embodiment of the present invention is to further improve the structure and control manner of the air conditioning device 100 for these severe cases.
Specifically, the air conditioning apparatus 100 further includes a concentration detecting member (not shown in the drawings) for detecting a concentration of the refrigerant in the electronic control box assembly 5, and the concentration detecting member is electrically connected to the electronic control box assembly 5 to transmit detected concentration information in the electronic control box assembly 5 to the electronic control box assembly 5. As shown in fig. 11, when the detected concentration is greater than or equal to the set value, it indicates that the refrigerant circulation system may leak refrigerant in the electronic control box assembly 5, and at this time, the electronic control box assembly 5 controls the air conditioning device 100 to stop, so as to avoid aggravation of the leakage condition.
According to the air conditioning device 100 provided by the embodiment of the invention, the electric control box assembly 5 is radiated by arranging the refrigerant radiating module 6, so that the electric control box assembly 5 can be quickly cooled, and stable and durable operation of electronic components is ensured. The box body of the electric control box assembly 5 is arranged to be a closed box body, so that external water flow and sundries can be prevented from entering the electric control box assembly 5 to interfere with the work of components, and external moisture can be prevented from entering the box body to generate condensed water to erode the components. By arranging the concentration detection part to monitor the concentration of the refrigerant in the electric control box assembly 5, whether the refrigerant leakage fault occurs in the device can be monitored, so that the operation reliability of the device is improved.
In some embodiments, the air conditioning device 100 further comprises: and an alarm (not shown) which sends out alarm information when the concentration is detected to be greater than or equal to a set value. Thus, the user can be timely informed of the maintenance operation.
In the embodiment of the present invention, in order to improve the heat dissipation capability of the electronic control box assembly 5, the structure of the electronic control box assembly 5 may be further improved.
For example, the case may be provided as a heat-conducting member, i.e., the case itself is capable of conducting out internal heat, thereby improving heat dissipation capability.
Specifically, the box body of the electric control box assembly 5 is a vacuum box, so that the air in the box body can be greatly reduced, and condensed water is difficult to generate in the box.
Optionally, the electric control box assembly 5 is filled with the insulating heat conducting member after being vacuumized, that is, air in the airtight box body of the electric control box assembly 5 can be pumped out, and materials with good insulating heat conducting performance are refilled. Thus, when the insulating heat conducting member is used, the heat of the component can be guided to the box body, and then the heat is dissipated from the box body to the outside air.
In the embodiment of the present invention, the refrigerant heat dissipation module 6 has various structural forms.
In some embodiments, the coolant heat dissipation module 6 includes at least one of a heat dissipation plate, a heat dissipation fin, and a heat dissipation fan. That is, the refrigerant heat-dissipating module 6 may include a heat-dissipating plate, the refrigerant heat-dissipating module 6 may include a heat-dissipating fin, the refrigerant heat-dissipating module 6 may include a heat-dissipating fan, the refrigerant heat-dissipating module 6 may include a heat-dissipating plate, a heat-dissipating fin, and a heat-dissipating fan, or the refrigerant heat-dissipating module 6 may include both of the above components.
In some embodiments, the coolant heat dissipation module 6 includes a semiconductor refrigeration sheet having a cold end for dissipating heat from the electronic control box assembly 5, and a hot end of the semiconductor refrigeration sheet dissipates heat to the outside, thereby improving heat transfer efficiency.

When the refrigerant cooling tube 61 is adopted, the refrigerant cooling tube 61 and the electric control box assembly 5 can be connected through heat dissipation plate structures such as aluminum plates and copper plates, the refrigerant cooling tube 61 can also be in direct contact with the electric control box assembly 5, and can also be connected through other components such as semiconductor refrigerating sheets, and the like, and the heat dissipation device is not limited.
In addition, in the refrigeration cycle path of the refrigerant cycle system, the position of the refrigerant heat dissipating tube 61 is also very flexible, for example, the refrigerant heat dissipating tube 61 may be installed upstream of the throttling element 3 (i.e. connected between the outdoor heat exchanger 2 and the throttling element 3), may be installed downstream of the throttling element 3 (i.e. connected between the indoor heat exchanger 4 and the throttling element 3), and the number of the throttling elements 3 may be set to be plural, so that the refrigerant heat dissipating tube 61 is connected in series between the two throttling elements 3, and thus the concentration of the refrigerant heat dissipating tube 61 may be flexibly adjusted.
In some embodiments, the refrigerant heat-dissipating pipe 61 is connected in series or parallel to the return air pipe 11 of the compressor 1, so that the return air concentration of the compressor 1 can be increased.
In the embodiment of the invention, the improvement and control mode aiming at the severe condition is applicable to a single cooling machine and a single heating machine and is also applicable to cooling and heating machines. In the following, a number of possible connection situations of the coolant heat dissipation module 6 are described in connection with different embodiments.
