[0018] The following is further described in detail through specific implementation methods:
[0019] The figure marks in the drawings of the specification include: mainboard waterproof box 1, waterproof box 2, DC variable frequency compressor 3, spray cooling solenoid valve 4, high-efficiency parallel flow heat exchanger 5, thermal expansion valve 6, internal threaded tube-type evaporator core 7, (ball bearing) evaporator fan 8, unit frame 9, pipeline 10, vertical drying bottle 11, vertical oil separator 12, (ball bearing) condensing fan 13, defrost solenoid valve 14, waterproof shell 15.
[0020] Example:
[0021] A structure for improving the waterproof performance of a refrigeration unit, such as Figure 1-Figure 3 As shown, the refrigeration unit comprises a waterproof housing 15 and a drainage assembly (not shown). The waterproof housing 15 is used to enclose the refrigeration unit. The waterproof housing 15 is made of a waterproof material. The waterproof material has a special molecular structure that can effectively prevent water molecules from penetrating. The housing is made of a corrosion-resistant, high-strength waterproof material. In this embodiment, the waterproof housing 15 is specifically made of fiberglass, which has the characteristics of corrosion resistance, aging resistance, light weight, high strength, and good waterproofness. The fiberglass is a composite of unsaturated polyester resin or epoxy resin and glass fiber. Both are environmentally friendly materials, non-toxic and harmless. The fiberglass material not only has outstanding environmental performance but also high safety, and is one of the important materials for promoting sustainable development.
[0022] The design of the waterproof housing 15 includes a sealing strip and a waterproof gasket to ensure that the connection between the housing and the unit components meets the IPX7 waterproof standard, effectively preventing moisture from intruding from the outside. The sealing strip is located at the connection between the waterproof housing 15 and the refrigeration unit, and the waterproof housing 15 is provided with a sealing groove for installing the sealing strip. The waterproof housing 15 blocks water molecules from penetrating into the waterproof unit, and the sealing strip is used to form a waterproof barrier between the waterproof housing 15 and the refrigeration unit to prevent rainwater, dew, etc. from intruding through the gaps. The connection parts of the housing use a double sealing process. Through the combination of customized waterproof sealant and precision-machined sealing grooves, a tight waterproof barrier is formed at the connection to prevent rainwater, dew, etc. from intruding through the gaps. Among them, the IPX7 waterproof standard is a set of waterproof performance test standards formulated by the International Electrotechnical Commission (International Electrotechnical Commission), which is mainly used to evaluate the waterproof performance of electronic products under short-term water immersion conditions. The IPX7 test standard requires electronic products to be tested in water at a depth of at least 1 meter for 30 minutes. During the test, the electronic products should be in working condition to verify their waterproof performance in actual use.
[0023] The refrigeration unit is also secured to the waterproof housing 15 via an adjustable mounting bracket. This allows for adaptability to refrigeration units of varying sizes while ensuring a tight fit between the housing and the unit, enhancing waterproof performance. In this embodiment, the adjustable mounting bracket is a telescopic bracket. The detailed structure is referenced in the prior art and will not be described in detail here.
[0024] The drainage assembly consists of a condensate collection tray, a water channel, and a drain piece, all connected in sequence. The condensate collection tray is located below the area of the refrigeration unit where water is likely to accumulate. The condensate collection tray collects condensate from the refrigeration unit and drains it through the water channel and drain piece, keeping the interior of the refrigeration unit dry.
[0025] The drainage component includes a drainage channel and a filter. The filter is located at the water inlet end of the drainage channel, and the drainage channel is connected to the water guide groove. The filter is set to filter the condensed water to avoid clogging the drainage channel.
[0026] The refrigeration unit is detachably connected to the waterproof housing 15. This facilitates removal of the waterproof housing 15 for maintenance and repair of the refrigeration unit. In this embodiment, the refrigeration unit is fixed to the waterproof housing 15 by bolts. This bolt-on method is simple and convenient.
[0027] The high-voltage control box also houses the 750V two-in-one electronic control assembly. The inner layer of the high-voltage control box is coated with a waterproof coating and enclosed within a waterproof box 2. A waterproof sealing ring is installed between the high-voltage control box and the waterproof box 2. The high-voltage control box further protects the corresponding components, minimizing moisture intrusion and damage. The waterproof sealing ring is a rubber sealing ring with excellent sealing performance, elasticity, chemical resistance, temperature resistance, and aging resistance.
[0028] The system also includes a motherboard waterproof box 1, which houses the control motherboard and is filled with waterproof and moisture-proof material. This provides further protection for the motherboard, minimizing damage from moisture. The box is made of waterproof material, whose unique molecular structure effectively blocks water penetration. Both the electronic control high-voltage box and the motherboard waterproof box feature quick assembly and disassembly designs.
[0029] For the heat dissipation vents of the refrigeration unit, which are easily ingressed by water, a labyrinth-type waterproof structure is designed. That is, the vents of the electrical box for installing related electrical equipment near the heat dissipation vents are set on the surface of the electrical box that does not correspond to the heat dissipation vents. This forms a tortuous air flow path, and the air flow can smoothly pass through the tortuous channel to achieve the heat dissipation function. Water is intercepted in the labyrinth structure due to gravity and surface tension and guided to a specially designed drainage channel for discharge.
[0030] The refrigeration unit includes a 750V two-in-one electronic control assembly, a DC variable frequency compressor 3, a spray cooling solenoid valve 4, a high-efficiency parallel flow heat exchanger 5, a thermal expansion valve 6, an internally threaded tube-type evaporator core 7, a (ball bearing) evaporator fan 8, a unit frame 9, a pipeline 10, a vertical drying bottle 11, a vertical oil separator 12, a (ball bearing) condensing fan 13 and a defrost solenoid valve 14 and other structures. The more detailed connection relationship, position relationship and refrigeration principle of the refrigeration unit between the structures are all referred to the existing technology and will not be described in detail here.
[0031] The electrical control box adopts a fully enclosed design. The internal electrical components are sealed in an independent waterproof cavity and are connected to the external circuit only through specially designed waterproof connectors to ensure that the electrical system is protected from moisture erosion and short circuits and other faults.
