[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The present utility model provides a heat dissipation device, which can be used in a water dispenser in conjunction with a refrigeration device. Figure 1 to Figure 2 As shown, it includes a condenser 1, an air duct member 3, and a fan 2. The fan 2 is used to take away the airflow around the condenser 1 to dissipate heat for the condenser. The air duct member 3 is arranged between the condenser 1 and the fan 2, and is located at the upper wind outlet of the fan 2. The air duct member 3 is hollow and has a certain length, so that the airflow around the condenser fins can flow through.

[0027] A ventilation duct with a hollow middle section connecting the condenser 1 and the fan 2 is formed in the duct member 3. The duct member 3 includes a plurality of duct plates, which form a frame structure along the circumferential direction, and the short sides of adjacent duct plates are butted together, and the cross section is polygonal. In the present embodiment, four rectangular duct plates are provided, and the short sides of adjacent rectangular plates are butted together to enclose a hollow rectangular channel. It should be noted that the duct member 3 can be a separately designed part or a component made by combining multiple parts as shown in the present embodiment, which is separately arranged and connected with other related parts; the duct member 3 can also be a part of the bracket of the fan 2 or the condenser 1 realized by different processing techniques such as bending and injection molding; the duct member 3 can also be realized by changing the outer shell of the condenser 1 or the fan 2, so that the outer shell of the condenser 1 extends to the side close to the fan 2 / the outer shell of the fan 2 extends to the side close to the condenser 1, and the cavity of the duct member 3 is extended.

[0028] A stopper 4 is provided on one side of the duct member 3 near the condenser 1. In this embodiment, two stoppers 4 are provided, located at the left and right ends of the duct member 3, for limiting the installation of the condenser 1; a certain gap is maintained between the stopper 4 and the outermost fin 9 of the condenser 1. A plurality of fins are distributed on the surface of the condenser 1. During installation, the stoppers 4 on the left and right sides of the duct member 3 correspond to the outermost fins 9 on the left and right sides of the condenser 1. When there is a gap between the stopper 4 and the outermost fin 9, it is convenient for the stopper 4 to match and limit the condenser 1. The size of the accommodating cavity of the duct member 3 is greater than or equal to the maximum outer dimension of the fin of the condenser 1. The maximum outer dimension is designed to be the length and width of all the fins on the surface of the condenser 1, so that the airflow generated by the heat exchange of the condenser 1 can be fully gathered in the accommodating cavity of the duct member 3, and discharged by the fan 2 after buffering, so that the noise reduction effect is better. In order to converge the airflow around the condenser 1 and fix the stopper 4, a vertical plate 8 is provided on the side of the duct member 3 close to the condenser 1, corresponding to the space between the outermost fin of the condenser 1 and the duct member 3. In this embodiment, the vertical plate 8 is connected to the side elevation of the duct member 3, and the position of the vertical plate 8 corresponding to the fin of the condenser 1 is hollow, so that the airflow around the condenser 1 flows into the duct member 3; the position of the vertical plate 8 corresponding to the outermost fin of the condenser 1 is provided with a stopper 4; the vertical plate 8 is also used to fix the outer fan 2.

[0029] The heat dissipation device also includes a bottom plate 6 and a pressure plate 5. The bottom plate 6 is located at the bottom end of the condenser 1 and the air duct member 3. The condenser 1 and the air duct member 3 are fixed on the bottom plate 6 after being fitted. In this embodiment, bolt fixing is adopted. A hole is opened on the bottom plate 6. Bolt holes are opened at corresponding positions of the condenser 1 and the air duct member 3. Of course, screws or other fixing methods can also be adopted. The pressure plate 5 is located at the top of the condenser 1 and the air duct member 3. After the condenser 1 and the air duct member 3 are fitted, the air duct member 3 can be fixed on the pressure plate 5. In this embodiment, the air duct member 3 and the pressure plate 5 are fixed by bolt fixing. A hole is opened on the pressure plate 5. Bolt holes are opened at corresponding positions of the air duct member 3. Of course, screws or other fixing methods can also be adopted; the condenser 1 and the pressure plate 5 are fixed by the bending portion limiter. The edge of the pressure plate 5 is bent downward to form a bending portion. The bending portion cooperates with the condenser 1, fits or leaves a certain gap close to the side wall of the condenser 1, and plays a role in limiting the position of the condenser 1.

[0030] The fan 2 includes a fan body and a first end face and a second end face. The first end face and the second end face are used to be fixedly connected to the duct member 3. In this embodiment, the first end face and the second end face are fixedly connected to the duct plate of the duct member 3 by fasteners such as screws. An air outlet is provided on the second end face, and the air outlet has an inclined surface, so that the air outlet of the fan 2 has directionality.

[0031] When the heat dissipation device is installed in the water dispenser, the heat dissipation device is aligned with a ventilation hole on a certain side of the water dispenser housing, which can effectively discharge air, effectively reduce noise, and enhance heat dissipation efficiency. In this embodiment, a housing ventilation hole 7 is provided on the water dispenser housing, such as Figure 3 As shown, the air outlet of the fan is aligned with the outer shell vent 7 of the water dispenser, and the air outlet of the fan is connected to the outer shell vent 7 to discharge the wind generated by the heat dissipation device inside the water dispenser out of the water dispenser. A gasket can be further added between the fan 2 and the outer shell vent 7 to allow more hot air to be discharged, and the hot air will not be blown back into the water dispenser from the gap between the fan 2 and the vent, causing the internal temperature to rise and affecting the heat dissipation. The gasket material can be sponge or rubber. The fan and the outer shell vent 7 can be tightly fitted by connecting means such as screws to achieve the same heat dissipation effect.

[0032] The heat dissipation device materials include but are not limited to plastic parts and metal parts.

[0033] like Figure 3 As shown, the working process of the utility model is:

[0034] The condenser 1, the air duct member 3 and the fan 2 are fixedly connected to form a heat dissipation device; the heat dissipation device is connected to the water dispenser, and the air outlet of the fan of the heat dissipation device is aligned with the outer shell ventilation hole 7 of the water dispenser.

[0035] The fan 2 sucks the cold air from the condenser side by blowing outward at high speed. The cold air flows through the dense high-temperature fins of the condenser 1, and cools the condenser 1 by heat exchange. Due to the dense arrangement of the fins, the velocity of the airflow increases when passing through the slits, and it becomes a series of fast eddies, causing the vibration of the molecules in the airflow and generating noise. Similar to the principle of whistling, when we whistle, the airflow interacts with the air molecules through the whistle's holes, causing the molecules to be excited and vibrate. Multiple fast eddies flow into the air duct member 3 between the fan 2 and the condenser 1 through the convergence of the vertical plate 8, and re-converge into one airflow in the air duct member 3. After buffering in the air duct member 3, the flow velocity is reduced, and the vibration of the air molecules is slowed down. Then, when the fan 2 rotates, it is blown out through the outer shell vents 7, and the overall noise is effectively reduced.

[0036] The utility model also discloses a water dispenser, comprising the above-mentioned heat dissipation device and a shell, wherein the heat dissipation device is located inside the shell.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
