[0002] In industries such as chemical engineering, medical treatment, scientific research, drilling, and manufacturing, many working environments are extremely hazardous, such as those containing large amounts of flammable gases. These hazardous environments are often accompanied by high temperatures, posing a significant threat to on-site personnel and electrical equipment. This is especially true for high-temperature areas such as control rooms, laboratories, operating rooms, and analytical rooms where on-site operation by personnel is essential. Cooling facilities are crucial to prevent serious injury to workers. Electrical equipment generating significant heat in hazardous environments must also be cooled to avoid damage. However, these hazardous locations are constrained by specific spatial conditions and technical requirements, necessitating high safety standards for cooling equipment.

[0003] Currently, explosion-proof air conditioners sold on the market are split-type air conditioners, which consist of an indoor unit and an outdoor unit. The outdoor unit needs to be placed outdoors for heat exchange. For buildings without an outdoor unit installation platform and some high-rise buildings, the installation and maintenance of the outdoor unit is difficult, the installation cost is high, and the project investment is large. The indoor unit needs to be placed indoors for cooling and air supply. In some special places, if the indoor environment does not have the conditions for installing air ducts, the installation requirements cannot be met. Therefore, we propose an explosion-proof water-cooled cabinet air conditioner to solve the above problems. Utility Model Content

The wiring between the explosion-proof compressor and the explosion-proof distribution box is connected by an explosion-proof flexible connecting pipe.

[0006] Furthermore, the jet assembly includes a static pressure chamber and a spherical nozzle, wherein the static pressure chamber and the spherical nozzle are sealed and fixedly connected.

[0007] Furthermore, an explosion-proof distribution box is installed inside the air conditioner housing. The explosion-proof distribution box has a sealed structure, uses an explosion-proof shell, and has threaded joints on the shell for cable wiring.

[0008] Furthermore, the outer shell of the explosion-proof motor is made of explosion-proof material, the explosion-proof motor has an external first sealed junction box, and the outer shell of the first sealed junction box has a threaded joint.

[0010] Furthermore, the explosion-proof compressor has a fully enclosed structure, with an external second sealed junction box, and a threaded joint is provided on the outer shell of the second sealed junction box.

[0011] Furthermore, the explosion-proof motor wiring adopts an explosion-proof flexible connector, with one end of the connector connected to the first junction box external to the explosion-proof motor and the other end connected to the explosion-proof distribution box.

[0012] Furthermore, the explosion-proof compressor wiring adopts an explosion-proof flexible connector, with one end of the connector connected to the external second sealed junction box of the explosion-proof compressor and the other end connected to the explosion-proof distribution box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

Inside the air conditioner housing 1, a filter screen 2, a heat exchange assembly 3, an explosion-proof fan 4, an explosion-proof motor 5, and a jet assembly 6 are arranged sequentially according to the airflow direction. The heat exchange assembly 3 includes an explosion-proof compressor 31, a shell-and-tube condenser 32, inlet and outlet water pipes 33, a capillary tube 34, and an evaporator 35. The explosion-proof compressor 31 is connected to the shell-and-tube condenser 32, the shell-and-tube condenser 32 is connected to the evaporator 35, and the evaporator 35 is connected to the explosion-proof compressor 31 to form a refrigeration circuit. The wiring between the explosion-proof compressor 31 and the explosion-proof distribution box 7 is connected by an explosion-proof flexible connecting pipe, which is a commercially available part. When air is driven by the explosion-proof fan 4, it passes through the filter screen 2 and the heat exchange component 3 in sequence to form cold air. After the air enters the static pressure box 61 in the jet component 6, the dynamic pressure of the air is converted into static pressure, and then it is ejected through the spherical nozzle 62. The explosion-proof water-cooled cabinet air conditioner of this application does not require an outdoor unit. It only needs to be connected to water as a cooling medium. When the corresponding project needs to be implemented, the above-mentioned air-cooled cabinet air conditioner only needs to be installed in the corner of the site. There is no need to install air ducts or outdoor unit installation platform, which reduces space occupation and reduces construction difficulty and project cost. In addition, this utility model uses an explosion-proof fan 4, an explosion-proof motor 5, an explosion-proof compressor 31 and an explosion-proof distribution box 7. The wiring method adopts explosion-proof and explosion-proof flexible connecting pipes, which can operate safely in flammable and explosive working environments and achieve stable air supply.

[0020] Example 2 like Figures 1-3 As shown, the jet assembly 6 includes a static pressure box 61 and a spherical nozzle 62, and the static pressure box 61 and the spherical nozzle 62 are sealed and fixedly connected. An explosion-proof distribution box 7 is installed inside the air conditioner housing 1. The explosion-proof distribution box 7 is a sealed structure with an explosion-proof shell, and the shell has threaded joints for cable wiring. The outer shell of the explosion-proof motor 5 is made of explosion-proof material. The explosion-proof motor 5 has an external first sealed junction box, and the outer shell of the first sealed junction box has a threaded joint. The explosion-proof fan 4 uses aluminum blades and iron inner walls, and is driven by an explosion-proof motor 5. The explosion-proof compressor 31 has a fully enclosed structure. The explosion-proof compressor 31 has an external second sealed junction box, and the outer shell of the second sealed junction box has a threaded joint. The explosion-proof motor 5 is connected to the explosion-proof flexible connector. One end of the explosion-proof flexible connector is connected to the first junction box outside the explosion-proof motor 5, and the other end is connected to the explosion-proof distribution box 7. The explosion-proof compressor 31 uses an explosion-proof flexible connection pipe for wiring. One end of the explosion-proof flexible connection pipe is connected to the external second sealed junction box of the explosion-proof compressor 31, and the other end is connected to the explosion-proof distribution box 7. The base assembly 14 is provided with a support structure, and the explosion-proof compressor 31, the sleeve condenser 32, and the inlet and outlet water pipes 33 are all arranged on the base assembly 14. The inlet and outlet water pipes 33 are connected to the sleeve condenser 32; Example 3 Furthermore, a copper filter is installed on the pipe connecting the shell-and-tube condenser 32 and the evaporator 35; Furthermore, a capillary tube 34 is installed at the inlet of the evaporator 35; Specifically, an explosion-proof distribution box 7 is provided on the lower side of the air conditioner housing 1. The explosion-proof distribution box 7 is equipped with control nodes for the explosion-proof motor 5 and the explosion-proof compressor 31. The explosion-proof distribution box 7 has a sealed design, which can effectively isolate dust and flammable and explosive gases. The interface of the explosion-proof distribution box 7 adopts a threaded connection. The wiring between the explosion-proof distribution box 7 and the external first sealed junction box of the explosion-proof motor 5 and the external second sealed junction box of the explosion-proof compressor 31 is run through an explosion-proof flexible connection pipe, which can effectively protect the cable and prevent external flames or sparks from entering the electrical equipment and causing an explosion. Furthermore, the explosion-proof distribution box 7 uses intrinsically safe circuits: Uo≤ 30V DC (typical value), Io≤ 100mA (Ex ia level), which controls the circuit energy below the minimum ignition energy of combustibles, ensuring that even if a short circuit, open circuit or other fault occurs, it will not ignite an explosive atmosphere; Specifically, the air conditioner housing 1 is provided with a partition 8, and the middle partition 8 is provided with an air outlet. The air outlet is connected to the explosion-proof fan 4. The partition 8 is located above the explosion-proof fan. The middle partition 8, the top plate 13, the front plate assembly 15, and the rear plate assembly 16 form a static pressure box 61, which converts the dynamic pressure of the air into static pressure and sends out the cold air through the spherical nozzle 62. Furthermore, to enhance the machine's explosion-proof capability, an explosion-proof fan 4 is used. The explosion-proof fan 4 has requirements for the impeller material and the corresponding material of the inner wall of the casing. It uses aluminum blades and iron inner walls, which are required to prevent sparks from being generated in the event of friction. An explosion-proof motor 5 is used, which uses non-combustible materials such as aluminum-magnesium alloy and stainless steel. These materials have high temperature resistance and corrosion resistance, which can effectively prevent sparks from being generated. Moreover, the explosion-proof motor 5 has a reasonable structural design, using explosion-proof shells and explosion-proof fillers to isolate the internal sparks of the motor from the external environment, ensuring that the motor will not cause an external explosion during operation. Specifically, the left side panel 11, right side panel 12, top panel 13, base assembly 14, front panel assembly 15, and rear panel assembly 16 are made of high-strength, corrosion-resistant stainless steel plates, which can be used for a long time in environments containing corrosive gases or liquids without easily rusting or corroding. This makes the explosion-proof air conditioner safer and more reliable in flammable and explosive environments. In addition, the stainless steel plate has high density and good strength, and can withstand greater pressure and impact, ensuring the stability and safety of the explosion-proof water-cooled cabinet unit in harsh environments.
