[0038] Reference Figures 1 to 4 The following are several embodiments of the refrigeration system and refrigeration equipment of this utility model.

[0039] like Figures 1 to 4 As shown, the refrigeration system of the first aspect of this utility model includes a heat exchanger 100, a water receiving tray 200, and an evaporation rope 300; the heat exchanger 100 has a heat pipe 110; the water receiving tray 200 is used to receive condensate generated by the refrigeration system; the evaporation rope 300 is connected to the heat pipe 110; the evaporation rope 300 is made of a hydrophilic material, and a first microchannel is formed on the evaporation rope 300, which extends along the length direction of the evaporation rope 300; a portion of the evaporation rope 300 is immersed in the condensate in the water receiving tray 200.

[0040] The heat exchanger 100 is used to dissipate heat from the refrigeration system to the environment. The water collection tray 200 collects the condensate generated by the refrigeration system. Part of the evaporation rope 300 is immersed in the condensate in the water collection tray 200. Utilizing the hydrophilicity of the evaporation rope 300 and the capillary action generated by the first microchannel, the condensate in the water collection tray 200 is continuously adsorbed onto the evaporation rope 300 to evaporate the condensate and prevent excessive accumulation of condensate and overflow. The evaporation rope 300 is connected to the heat pipe 110. The heat from the heat pipe 110 is transferred to the evaporation rope 300 to accelerate the evaporation of water on the evaporation rope 300 and prevent the water collection tray 200 from overflowing.

[0041] like Figures 1 to 4As shown, in some embodiments, the refrigeration system also includes a semiconductor refrigeration chip, and the condensate generated at the cold end of the semiconductor refrigeration chip is collected in the drip tray 200. In high temperature and high humidity environments or when the door is frequently opened, the condensate generation rate exceeds the natural evaporation rate, causing the drip tray 200 to overflow. In this embodiment of the invention, an evaporation rope 300 is used to absorb the condensate in the drip tray 200. The condensate evaporates on the evaporation rope 300, and the waste heat of the heat pipe 110 is used to accelerate the evaporation rate. No other additional devices are required, reducing space occupation. The heat exchanger 100 can be a heat pipe radiator. The heat exchanger 100 has a heat pipe 110 and is used to dissipate the heat from the hot end of the semiconductor refrigeration chip. When the refrigeration system is running, the temperature of the heat pipe 110 is usually maintained at 32-50°C. The evaporation rope 300 is connected to the heat pipe 110. By utilizing the waste heat of the heat exchanger 100, the evaporation of water in the evaporation rope 300 can be accelerated without an additional heat source, and there is no need for manual emptying of water.

[0042] Utilizing capillary action, condensate from the drip tray 200 is drawn onto the evaporation rope 300 without requiring an additional power source, significantly increasing the effective volume of the drip tray 200. Furthermore, the evaporation of water carries away heat (approximately 2400 kJ / kg), lowering the temperature of the heat pipe 110 by 3-8°C and simultaneously improving cooling efficiency. By drawing condensate from the drip tray 200 through the evaporation rope 300, the condensate evaporates on the rope, and the heat from the heat pipe 110 accelerates the evaporation rate, ensuring that the evaporation rate exceeds the maximum condensate generation rate. This effectively manages the condensate and prevents overflow from the drip tray 200.

[0043] like Figures 1 to 4 As shown, in some embodiments, a hollow channel 301 is formed inside the evaporation rope 300, and the inner diameter of the hollow channel 301 is 0.1mm-1mm. By designing the interior of the evaporation rope 300 as an extremely fine hollow channel 301 with an inner diameter of 0.1mm-1mm, the capillary adsorption effect is significantly enhanced, which can more efficiently and continuously adsorb the condensate in the water receiving tray 200 to the entire evaporation rope 300. Through the hollow channel 301, the amount of condensate adsorbed by the evaporation rope 300 can be increased, which is conducive to realizing the rapid and efficient evaporation treatment of condensate in the water receiving tray 200.

[0044] like Figures 1 to 4As shown, in some embodiments, the evaporation rope 300 includes an evaporation section 310 and two water-absorbing ends 320 connected to both ends of the evaporation section 310. The water-absorbing ends 320 are located below the condensate liquid surface of the water receiving pan 200, so that the condensate in the water receiving pan 200 flows from the water-absorbing ends 320 to the evaporation section 310, where the condensate evaporates. The evaporation section 310 is wound around the heat pipe 110, which can increase the contact area between the heat pipe 110 and the evaporation section 310, facilitating the transfer of heat from the heat pipe 110 to the evaporation section 310, so that the condensate evaporates quickly. In addition, the evaporation section 310 is wound around the heat pipe 110, which can improve the firmness of the connection between the evaporation rope 300 and the heat pipe 110, so that the evaporation rope 300 can be fixed to the evaporation section 310 without additional fixing parts.

[0045] like Figures 1 to 4 As shown, in some embodiments, the evaporation section 310 is wound with the heat pipe 110 at a density of 5-8 turns per centimeter to increase the contact area between the evaporation section 310 and the heat pipe 110, thereby ensuring that the heat generated by the heat pipe 110 can be efficiently transferred to the condensate adsorbed on the evaporation section 310. This arrangement achieves maximum heat exchange efficiency within a limited space, significantly accelerating the evaporation rate of water. Furthermore, increasing the number of winding turns of the evaporation section 310 enhances the stability of the connection between the evaporation rope 300 and the heat pipe 110. During the operation of the refrigeration system, the efficient cooperation between the evaporation rope 300 and the heat pipe 110 allows the condensate to evaporate rapidly, carrying away a large amount of heat, thereby effectively reducing the temperature of the refrigeration system and improving the overall cooling effect. The winding pitch of the evaporation section 310 can be 8 mm to maximize the contact area.

[0046] like Figures 1 to 4 As shown, in some embodiments, the refrigeration system further includes a cover 400, with the cover 400 and the evaporation section 310 located above the water receiving pan 200. The cover 400 is used to shield the portion of the evaporation section 310 that contacts the heat pipe 110. Since the water suction end 320 is immersed below the liquid surface of the water receiving pan 200, and the evaporation section 310 is located above the water receiving pan 200, the water suction end 320 can naturally fall into the water receiving pan 200. By setting the cover 400 above the water receiving pan 200, the portion of the evaporation section 310 that contacts the heat pipe 110 is shielded, forming a relatively closed and high-temperature local environment to prevent heat loss. This concentrates the heat from the heat pipe 110 and raises the temperature inside the cover, significantly accelerating the evaporation rate of the condensate. It also serves to prevent dust and dirt accumulation, ensuring long-term stable operation of the system. In other embodiments, the cover 400 shields the entire evaporation section 310, and this embodiment of the present invention does not impose any particular limitation on this. The cover 400 is fixed to the outer shell of the heat exchanger 100, so that a relatively closed evaporation space is formed between the cover 400 and the outer shell of the heat exchanger 100, and the evaporation section 310 evaporates in the evaporation space.

[0047] like Figures 1 to 4 As shown, in some embodiments, the surface of the cover 400 is provided with multiple vent holes 410; when the condensate in the evaporation section 310 comes into contact with the heat pipe 110, it absorbs a large amount of heat from the heat pipe 110 and evaporates to form water vapor. The water vapor is discharged through the vent holes 410, preventing the evaporation rate from being suppressed due to steam saturation inside the cover 400. Generally, the multiple vent holes 410 are arranged in a matrix on the surface of the cover 400 for easy processing.

[0048] like Figures 1 to 4 As shown, in some embodiments, the aperture of the vent 410 is 2mm-4mm; this ensures sufficient convective exchange between the heated humid air inside the enclosure and the dry air outside, thus maintaining a continuously efficient evaporation environment, while also effectively preventing heat dissipation from the heat pipe 110, which is beneficial for the evaporation of condensate. If the aperture of the vent 410 is too small, water vapor cannot be discharged in time, affecting the evaporation of condensate; if the aperture of the vent 410 is too large, heat will dissipate rapidly through the vent 410, reducing evaporation efficiency. In this embodiment, the aperture of the vent 410 is 3mm. In this embodiment, the diameter of the evaporation rope 300 is 3mm and the length is 40cm.

[0049] like Figure 5 As shown, in some embodiments, the cooling system further includes a water tank 520 and a water-absorbing rope 530, the water-absorbing rope 530 being connected to the heat pipe 110; the water-absorbing rope 530 is made of a hydrophilic material, and a second microchannel is formed on the water-absorbing rope 530, extending along the length of the water-absorbing rope 530; a portion of the water-absorbing rope 530 is immersed in the water in the water tank 520; the water tank 520 is filled with water; the portion of the water-absorbing rope 530 is immersed in the water in the water tank 520, utilizing the hydrophilicity of the water-absorbing rope 530 and the capillary action generated by the second microchannel, continuously adsorbing water from the water tank 520 onto the water-absorbing rope 530, and through the evaporation of water on the water-absorbing rope 530, carrying away heat from the heat pipe 110, thereby reducing the temperature of the hot end of the semiconductor cooling chip, and thus improving energy efficiency. The cooling system also includes a back plate 510, through which the water tank 520 is fixed to the outer casing of the cooling device.

[0050] The evaporation rope 300 and the water absorption rope 530 are wound around the heat pipe 110 in a double or multi-strand manner. The water tank 520 can be connected to a water source, so that water can be continuously added to the water tank 520 to maintain the water level in the water tank 520.

[0051] like Figures 1 to 4As shown, in some embodiments, the evaporation rope 300 is made of hydrophilic modified polyester material. Modified polyester refers to traditional polyester fibers that have undergone some form of modification treatment. Hydrophilic groups can be introduced onto the surface of the polyester fibers through plasma treatment technology, thereby greatly improving the material's superhydrophilicity and capillary adsorption capacity without altering its original high strength, corrosion resistance, and other excellent intrinsic properties. This allows the evaporation rope 300 to more quickly and continuously absorb condensate from the water receiving tray 200, utilizing heat to achieve rapid evaporation of the water. Simultaneously, the modified polyester material also possesses good air permeability and abrasion resistance, ensuring that the evaporation rope 300 maintains high evaporation efficiency during use while withstanding a certain degree of mechanical friction and wear, extending the service life of the evaporation rope 300. For example, the material of the evaporation rope 300 can be the modified polyester with good hydrophilicity and antistatic properties disclosed in Chinese Patent Publication No. CN101367912B.

[0052] like Figures 1 to 4 As shown, in some embodiments, the hydrophilic contact angle of the evaporation rope 300 is less than 30°, and the water absorption rate is ≥300%. Controlling the hydrophilic contact angle of the evaporation rope 300 to less than 30 degrees ensures that the water absorption rate of the evaporation rope 300 is greater than or equal to 300%. By giving the evaporation rope 300 a super-hydrophilic contact angle of less than 30° and a high water absorption rate of ≥300%, it is endowed with hydrophilic properties and water storage capacity, increasing the effective volume of the water receiving tray 200 by more than 200%. The hydrophilic surface ensures that condensate can be instantly wetted. The water absorbs and spreads rapidly throughout the evaporation rope 300. The extremely high water absorption rate means that it can hold and transport a large amount of water, significantly enhancing the capillary water conduction efficiency. The waste heat of the heat pipe 110 is used to achieve high-speed evaporation of condensate. In continuous operation, the evaporation rope 300 can continuously absorb condensate from the water collection pan 200 and promptly transport it to the heat pipe 110 for evaporation, effectively preventing the accumulation of condensate in the water collection pan 200 and reducing the risk of system efficiency decline or failure due to excessive water accumulation.

[0053] The second aspect of this utility model provides a refrigeration device, which is the refrigeration system described in the first aspect of the present invention.

However, the present utility model is not limited to the above embodiments. 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.
