[0002] An integrated air conditioning unit typically contains a condenser chamber and an evaporator chamber, separated by a partition. The condenser chamber usually integrates the condenser, compressor, and condenser fan; the evaporator chamber contains the evaporator fan and evaporator.

[0003] The control box is usually installed in the condenser chamber, and it is cooled by outdoor air drawn in by the condenser fan. However, when the outdoor temperature is high, the cooling effect of the outdoor air on the control box will be significantly reduced. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an integrated air conditioner that facilitates heat dissipation of the control box. It can utilize the cold air in the evaporator cavity to dissipate heat from the control box, thereby improving the heat dissipation effect of the control box, while also reducing the space occupied by the control box in the evaporator cavity and preventing the cold air in the evaporator cavity from entering the control box.

[0005] An integrated air conditioner according to an embodiment of the present invention, which facilitates heat dissipation of the control box, includes a chassis and a control box. The chassis has a partition, a condensing chamber, and an evaporating chamber inside, and the condensing chamber and the evaporating chamber are separated by the partition. The control box includes a body, a circuit system, and a heat dissipation module. The body passes through the partition, with a first end of the body located in the evaporating chamber and a second end of the body located in the condensing chamber. The circuit system includes a first circuit board and at least one second circuit board. The first circuit board integrates a power supply circuit, and the power of the second circuit board is less than that of the first circuit board.

[0006] The integrated air conditioner for heat dissipation of the control box according to the embodiments of the present invention has at least the following beneficial effects: The integrated air conditioner provided by the present invention places the heat dissipation module of the control box inside the evaporation chamber, thereby utilizing the cold air inside the evaporation chamber to dissipate heat from the first circuit board of the control box, improving the heat dissipation effect of the control box. Placing one end of the control box in the evaporation chamber and the other end in the condensation chamber reduces the space occupied by the control box inside the evaporation chamber and reduces the impact of the control box on the airflow inside the evaporation chamber. Secondly, the heat dissipation module seals the first mounting hole of the box body, thus sealing the first end of the box body and preventing cold air from the evaporation chamber from entering the control box, causing the first or second circuit board to become damp or frosted. Furthermore, the circuit system of the control box includes a high-power first circuit board and a low-power second circuit board, with the low-power second circuit board placed inside the second end of the box body. This prevents the heat dissipation module from transferring cold energy to the low-power second circuit board, thus avoiding excessively low circuit temperatures for the low-power second circuit board and ensuring its normal operation.

The base plate is located inside the first end of the housing. The base plate is sealed to the side wall of the first mounting hole. The heat dissipation fin is inserted into the evaporation chamber through the first mounting hole.

[0008] According to some embodiments of this utility model, the condensation chamber and the evaporation chamber are arranged side by side, and the control box is disposed at the upper end of the partition.

[0009] According to some embodiments of the present invention, an evaporation fan and an evaporator are provided inside the evaporation chamber, the evaporator and the evaporation fan are arranged in a front-to-back manner, and the evaporation fan is located on the lower side of the control box.

[0010] According to some embodiments of the present invention, the upper outer wall of the chassis is at least partially configured as a detachable or closable top cover, the box body includes a bottom shell and a cover, the cover is detachably or removably installed on the upper end of the bottom shell, the first circuit board and the second circuit board are disposed inside the bottom shell, the first mounting hole is disposed in the bottom shell, and the cover is located between the bottom shell and the top cover.

[0023] Reference Figures 1 to 3 An integrated air conditioner according to an embodiment of the present invention, which facilitates heat dissipation of the control box, includes a chassis 100 and a control box. The chassis 100 has a partition 110, a condensing chamber 120, and an evaporating chamber 130 inside, separated by the partition 110. The control box includes a body 210, a circuit system 220, and a heat dissipation module 230. The body 210 passes through the partition 110, with its first end located inside the evaporating chamber 130 and its second end located inside the condensing chamber 120. The circuit system 220 includes a first circuit board 221 and at least one second circuit board. 222, The first circuit board 221 integrates a power supply circuit, the power of the second circuit board 222 is less than the power of the first circuit board 221, the first circuit board 221 is located inside the first end of the housing 210, the second circuit board 222 is located inside the second end of the housing 210, the second circuit board 222 is electrically connected to the first circuit board 221, the heat dissipation module 230 is installed on the first circuit board 221, wherein the first end of the housing 210 is provided with a first mounting hole 211, the heat dissipation module 230 is inserted into the evaporation chamber 130 through the first mounting hole 211, and the heat dissipation module 230 closes the first mounting hole 211.

[0024] The main components and principles of the air conditioner's circuit system 220 are conventional technologies in this field. Its circuit components include a power supply circuit, a main control circuit, a detection circuit, a communication circuit, etc. The specific circuit settings will not be described in detail here.

[0025] The first circuit board 221 mainly integrates the power supply circuit. The main components of the power supply circuit include the AC input interface, fuse, filter capacitor, mutual inductance filter, rectifier diode, and bridge rectifier. The entire power supply circuit has high power and generates a lot of heat, so a heat dissipation module 230 is required to dissipate it.

[0026] In practice, the main control circuit can also be integrated onto the first circuit board 221.

[0027] The second circuit board 222 can integrate low-power circuits such as detection circuits and communication circuits. Therefore, the second circuit board 222 has low power and generates less heat, so it does not require heat dissipation module 230 for heat dissipation.

[0028] The integrated air conditioner provided by this utility model places the heat dissipation module 230 of the control box inside the evaporation chamber 130, thereby utilizing the cold air inside the evaporation chamber 130 to dissipate heat from the first circuit board 221 of the control box, improving the heat dissipation effect of the control box. Placing one end of the control box in the evaporation chamber 130 and the other end in the condensation chamber 120 reduces the space occupied by the control box inside the evaporation chamber 130 and minimizes its impact on airflow within the evaporation chamber 130. Furthermore, the heat dissipation module 230 seals the first mounting hole 211 of the housing 210, thus sealing the first end of the housing 210 and preventing cold air from the evaporation chamber 130 from entering the control box and causing damage to the first circuit board 221 or... The second circuit board 222 is susceptible to moisture and frost. In addition, the circuit system 220 of the control box includes a high-power first circuit board 221 and a low-power second circuit board 222. The low-power second circuit board 222 is placed inside the second end of the box body 210. This can prevent the heat dissipation module 230 from transferring cold energy to the low-power second circuit board 222, which would cause the circuit temperature of the low-power second circuit board 222 to be too low. This ensures that the second circuit board 222 can work normally. At the same time, it also avoids the situation where the temperature difference between the high-power circuit and the low-power circuit in a single circuit board is too large, reducing the probability of circuit system 220 failure and ensuring the service life of the entire circuit system 220.

[0029] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the heat dissipation module 230 includes a base plate 231 and heat sinks 232 disposed on the base plate 231. The base plate 231 is located inside the first end of the housing 210, and the base plate 231 is sealed to the side wall of the first mounting hole 211. The heat sinks 232 are inserted into the evaporation chamber 130 through the first mounting hole 211. With the above arrangement, the heat dissipation module 230 can seal the first mounting hole 211, thereby preventing humid and cold air in the evaporation chamber 130 from entering the first end of the housing 210 through the first mounting hole 211. The heat dissipation module 230 has a simple structure and is easy to install.

[0030] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the condensation chamber 120 and the evaporation chamber 130 are arranged side by side, and the control box is installed at the upper end of the partition 110. This effectively prevents condensate from entering the control box from the evaporation chamber 130, protecting the circuit system 220 within the control box.

[0031] Reference Figure 3 According to some embodiments of the present invention, an evaporator fan 600 and an evaporator 500 are provided in the evaporation chamber 130. The evaporator 500 and the evaporator fan 600 are arranged in a front-to-back manner. The evaporator fan 600 is located below the control box. Thus, the control box is far away from the evaporator 500 and avoids the evaporator fan 600, thereby reducing the influence of the control box on the flow of cold air inside the evaporation chamber 130.

[0032] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, at least part of the upper outer wall of the chassis 100 is configured as a detachable or closable top cover 140. The box body 210 includes a bottom shell 210a and a cover 210b. The cover 210b is detachably or closably mounted on the upper end of the bottom shell 210a. A first circuit board 221 and a second circuit board 222 are disposed inside the bottom shell 210a. A first mounting hole 211 is disposed in the bottom shell 210a. The cover 210b is located between the bottom shell 210a and the top cover 140. With the above configuration, the circuit system 220 inside the control box can be maintained simply by disassembling or opening the top cover 140 and the cover 210b in sequence, making maintenance convenient and simple.

[0033] Reference Figure 3 According to some embodiments of this utility model, at least one wire passage hole 212 is provided at the second end of the housing 210. A cable is electrically connected to the first circuit board 221 or the second circuit board 222, and the cable passes through the wire passage hole 212. By setting the wire passage hole 212 at the second end of the housing 210, it is unnecessary to consider the problem of cold air in the evaporation chamber 130 entering the interior of the housing 210 through the wire passage hole 212, thus eliminating the need for a sealing design between the wire passage hole 212 and the cable.

[0034] Reference Figure 3 According to some embodiments of this utility model, the partition 110 has a second mounting hole 112, and the side wall of the second mounting hole 112 is provided with a flange 111. The box body 210 passes through the second mounting hole 112, and the flange 111 is attached to and fixedly connected to the box body 210. With the above configuration, the control box can be stably and reliably installed on the partition 110.

[0035] Reference Figure 1 According to some embodiments of the present invention, a compressor 300 and a condenser 400 are provided inside the condensing chamber 120.

[0036] Reference Figure 1 According to some embodiments of this utility model, the aforementioned integrated air conditioner is a ground source heat pump air conditioner, which is a highly efficient and energy-saving system that utilizes shallow geothermal resources such as soil, groundwater, or surface water to achieve cooling, heating, and domestic hot water supply. Its core principle is to use heat pump technology to upgrade low-temperature geothermal energy to high-temperature heat energy. In the ground source heat pump air conditioner, the condenser 400 is a coil-type heat exchanger to facilitate heat exchange between the refrigerant and the hot water formed by the geothermal resources.

[0037] In the specific implementation process, the coil heat exchanger is installed on the compressor 300, thereby achieving a compact layout and reducing the required size of the condensing chamber 120.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
