Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fans, in particular to a cooling mechanism and an axial flow fan. Background Art

[0002] Axial flow fans direct airflow in the same direction as the fan's axis. They're called axial because the air flows parallel to the fan's shaft. Axial flow fans are typically used in applications where high flow rates and low pressures are required. Axial flow fans are fixed in position and move air. Axial flow fans primarily consist of a fan impeller and a casing.

[0003] Existing axial flow fans usually only flow natural air through rotating blades during use. When the temperature is hot, the temperature of the flowing natural air is still relatively hot. When cooling the air inside the factory, the axial flow fan still delivers natural air with a relatively high temperature, which has a poor cooling effect on the space. Therefore, we propose a cooling mechanism and an axial flow fan. Utility Model Content

[0004] The purpose of the present invention is to provide a cooling mechanism and an axial flow fan to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cooling mechanism, comprising a storage box, an ice crystal box is provided inside the storage box, and a plurality of ice crystal boxes are provided. A water leakage hole 1 is provided inside the bottom end surface of the storage box, and a fixed frame is provided at the bottom end of the storage box. The storage box is connected to the fixed frame through the water leakage hole 1, and water-containing cotton is installed on the inner side of the fixed frame. A water leakage hole 2 is provided inside the bottom end surface of the fixed frame, and a water collection box is installed at the bottom end of the fixed frame. The fixed frame is connected to the water collection box through the water leakage hole 2.

[0006] Furthermore, a heat-insulating cover is provided on the top of the storage box, and the heat-insulating cover is arc-shaped. The heat-insulating cover covers the storage box, which is beneficial to prolonging the melting time of ice cubes inside the ice crystal box.

[0007] Furthermore, grooves are provided on both sides of the ice crystal box, and the grooves are in the shape of rectangular strips.

[0008] Furthermore, a spring is installed at the inner bottom end of the storage box, and a top supporting plate is provided at the top end of the spring.

[0009] Furthermore, the water-containing cotton is bonded to the fixing frame, and two water-containing cottons are provided.

[0010] Furthermore, water pumps are installed at both ends of the water collection box, and one side of the water pump is connected to a connecting pipe.

[0011] An axial flow fan comprises an axial flow fan body, on which a cooling mechanism as described in any one of the above items is installed.

[0012] The utility model provides a cooling mechanism and an axial flow fan, which have the following beneficial effects: the water source inside the storage box contacts the ice crystal box, and the water source flows from the grooves on both sides of the ice crystal box, which can reduce the temperature of the water source. The cooled water source flows through the water-containing cotton through the water leakage hole, forming a water curtain inside the water-containing cotton, which is conducive to reducing the temperature of the air at the air inlet end of the axial flow fan body, and the cooled air is then output through the axial flow fan body;

[0013] 1. The operator of the utility model can place the frozen ice crystal box in the storage box. The supporting plate can gently support the ice crystal box through the spring. Since the storage box has a certain depth, on the one hand, it can prevent the ice crystal box from colliding with the bottom of the storage box during the storage process, causing damage to the ice crystal box. On the other hand, the ice crystal box can be kept at a certain height from the bottom of the storage box to avoid blocking the water leakage hole.

[0014] 2. The water source inside the water collection box of the utility model can be transported to the storage box through a water pump and a connecting pipe. The water source inside the storage box contacts the ice crystal box, which can reduce the temperature of the water source.

[0019] like Figure 1-3As shown, a cooling mechanism and an axial flow fan include a storage box 2, an ice crystal box 4 is provided inside the storage box 2, and a plurality of ice crystal boxes 4 are provided. A heat-insulating cover 3 is provided on the top of the storage box 2, and the heat-insulating cover 3 is arc-shaped. The heat-insulating cover 3 covers the storage box 2, which is conducive to prolonging the melting time of ice cubes inside the ice crystal box 4. Grooves 5 are provided on both sides of the ice crystal box 4, and the grooves 5 are rectangular strips. A spring 7 is installed at the bottom end of the storage box 2, and a supporting top plate 6 is provided at the top of the spring 7. A water leakage hole 8 is provided inside the bottom end surface of the storage box 2, and a fixing frame 9 is provided at the bottom end of the storage box 2. The storage box 2 is connected to the fixing frame 9 through the water leakage hole 8;

[0020] The operator can place the frozen ice crystal box 4 in the storage box 2, and the support plate 6 can gently support the ice crystal box 4 through the spring 7. Since the storage box 2 has a certain depth, on the one hand, it can prevent the ice crystal box 4 from colliding with the bottom of the storage box 2 during the process of being placed in the storage box 2, causing damage to the ice crystal box 4. On the other hand, the ice crystal box 4 can be separated from the bottom of the storage box 2 by a certain height to avoid blocking the water leakage hole 8.

[0021] like Figure 1 As shown, a water-containing cotton 10 is installed on the inner side of the fixed frame 9. The water-containing cotton 10 is bonded to the fixed frame 9, and two water-containing cottons 10 are provided. A second water leakage hole 11 is opened inside the bottom end surface of the fixed frame 9, and a water collection box 12 is installed at the bottom end of the fixed frame 9. The fixed frame 9 is connected to the water collection box 12 through the second water leakage hole 11. Water pumps 13 are installed at both ends of the water collection box 12, and a connecting pipe 14 is connected to one side of the water pump 13.

[0022] The water source inside the water collection box 12 can be transported to the storage box 2 through the water pump 13 and the connecting pipe 14. The water source inside the storage box 2 contacts the ice crystal box 4, which can reduce the temperature of the water source. The cooled water source flows through the water leakage hole 8 and the water-containing cotton 10, which is beneficial to reduce the air temperature at the air inlet end of the axial flow fan body 1. The cooled air is then output through the axial flow fan body 1.

[0023] An axial flow fan comprises an axial flow fan body 1, on which the above-mentioned cooling mechanism is installed.

[0024] In summary, when the cooling mechanism and the axial flow fan are used, first, the operator opens the heat preservation cover 3, adds a certain amount of water to the storage box 2, and makes the water flow into the water collection box 12, and then puts the frozen ice crystal box 4 into the storage box 2. The top support plate 6 gently supports the ice crystal box 4 through the spring 7 to prevent the ice crystal box 4 from colliding with the bottom of the storage box 2 during the process of putting the ice crystal box 4 into the storage box 2. The top support plate 6 and the spring 7 make the ice crystal box 4 and the bottom of the storage box 2 spaced at a certain height to avoid blocking the water leakage hole 8. The inside of the water collection box 12 The water source is transported to the storage box 2 through the water pump 13 and the connecting pipe 14. The water source inside the storage box 2 contacts the ice crystal box 4. The water source flows while contacting through the groove 5 on the surface of the ice crystal box 4, thereby reducing the temperature of the water source. The cooled water source flows through the water-containing cotton 10 through the leaking hole 8. The flowing water source forms a water curtain in the water-containing cotton 10, which is beneficial to reducing the air temperature at the air inlet end of the axial flow fan body 1. The cooled air is then output through the axial flow fan body 1. This is the working principle of the cooling mechanism and the axial flow fan.
