When the internal system of refrigeration equipment is working, especially when the electric control box is working, there are many electronic components inside, and heat dissipation needs to be carried out in time to ensure the normal operation of the refrigeration system or electrical automatic control system.

[0003] Related technology discloses an electric control box, an air conditioner outdoor unit and an air conditioner. The electric control box includes a shell assembly and a waterproof assembly. The shell assembly includes a shell with a heat dissipation duct formed inside. The shell is provided with a vent. The heat dissipation duct is connected to the outside of the shell through the vent. The waterproof assembly includes a waterproof cover, which is arranged outside the shell, and the waterproof cover is arranged outside the vent. The waterproof cover has an air outlet connecting the inside and outside of the waterproof cover, and the ventilation cross-sectional area of ​​the air outlet is smaller than the ventilation cross-sectional area of ​​the vent. The waterproof cover has an air inlet, which is connected to the vent. A waterproof assembly is arranged outside the shell of the electric control box, and the waterproof assembly is used to block water droplets or dust outside the electric control box from entering the electric control box. At the same time, the waterproof assembly will not affect the circulation of airflow inside and outside the electric control box, and can guide the circulating airflow between the inside of the electric control box and the main air duct, thereby increasing the flow rate of the airflow outflowing from the electric control box, thereby improving the heat dissipation efficiency.

[0005] The relevant technology can achieve the circulation of internal and external airflow through the coordination of vents, air inlets and air outlets. However, since the waterproof cover is set relative to the air inlet, although it has good waterproof properties, the setting of the waterproof cover will affect the ventilation volume inside and outside, affect the heat dissipation effect, and make the external surface of the chiller less smooth.

[0045] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0047] At present, refrigeration equipment is widely used in all walks of life. Refrigeration equipment basically includes refrigeration system and electrical automatic control system. When the internal system of refrigeration equipment is working, especially when the electric control box is working, there are many electronic components inside, and heat dissipation needs to be carried out in time to ensure the normal operation of the refrigeration system or electrical automatic control system.

[0048] Related technology discloses an electric control box, an air conditioner outdoor unit and an air conditioner. The electric control box includes a shell assembly and a waterproof assembly. The shell assembly includes a shell with a heat dissipation duct formed inside. The shell is provided with a vent. The heat dissipation duct is connected to the outside of the shell through the vent. The waterproof assembly includes a waterproof cover, which is arranged outside the shell, and the waterproof cover is arranged outside the vent. The waterproof cover has an air outlet connecting the inside and outside of the waterproof cover, and the ventilation cross-sectional area of ​​the air outlet is smaller than the ventilation cross-sectional area of ​​the vent. The waterproof cover has an air inlet, which is connected to the vent. A waterproof assembly is arranged outside the shell of the electric control box, and the waterproof assembly is used to block water droplets or dust outside the electric control box from entering the electric control box. At the same time, the waterproof assembly will not affect the circulation of airflow inside and outside the electric control box, and can guide the circulating airflow between the inside of the electric control box and the main air duct, thereby increasing the flow rate of the airflow outflowing from the electric control box, thereby improving the heat dissipation efficiency.

[0049] The relevant technology can achieve the circulation of internal and external airflow through the coordination of vents, air inlets and air outlets. However, since the waterproof cover is arranged relative to the air inlet, although it has good waterproof performance, the setting of the waterproof cover will affect the ventilation volume inside and outside, thereby affecting the heat dissipation effect.

[0050] Combination Figure 1-11 As shown, an embodiment of the present disclosure provides a ventilation structure for a chiller, comprising a first ventilation member 1 and a second ventilation member 2 .

[0051] like Figure 1-3 As shown, the first ventilation member 1 is provided with a first ventilation opening 11, which is configured to be set on a side facing the inside of the chiller; the second ventilation member 2 is opposite to the first ventilation member 1 and is spaced apart, and is provided with a second ventilation opening 21, which is configured to be set on a side facing the outside of the chiller; wherein the first ventilation opening 11 and the second ventilation opening 21 are staggered.

[0052] The ventilation structure and the chiller for a water chiller provided by the embodiment of the present disclosure are adopted. The relatively arranged first ventilation member 1 and the second ventilation member 2 are respectively provided with first vents 11 and second vents 21 arranged alternately. During ventilation, the airflow passes through the first vents 11 and the second vents 21 to enter and exit the water chiller. Compared with the related art in which a waterproof cover is provided on the outside of the vent, the present application increases the ventilation volume of the ventilation structure, the air circulation is smoother, and the heat dissipation effect on the water chiller is better.

[0053] In addition, the first ventilation opening 11 and the second ventilation opening 21 are arranged in a staggered manner so that water outside the chiller is not easy to enter the interior, and the ventilation structure has good waterproof performance on the basis of ensuring the ventilation volume. Moreover, the first ventilation member 1 and the second ventilation member 2 are arranged oppositely and at intervals, so that the chiller looks flatter and more beautiful from the outside.

[0054] Optionally, the ventilation structure also includes a first flange 31 and a second flange 32, the first flange 31 is arranged at the first ventilation opening 11, and extends in the direction of the second ventilation member 2; the second flange 32 is arranged at the second ventilation opening 21, and extends in the direction of the first ventilation member 1; wherein, under the guiding action of the first flange 31 and the second flange 32, the airflow flows into the first ventilation opening 11 and flows out of the second ventilation opening 21, or flows into the second ventilation opening 21 and flows out of the first ventilation opening 11.

[0055] When the chiller is working, a large amount of heat will be generated inside, and the external air temperature will be lower than the internal air temperature. Under the guiding effect of the second flange 32, the outside air enters the ventilation structure through the second vent 21 of the second ventilation member 2, and the airflow reaches the first ventilation member 1. Under the guiding effect of the first flange 31, it enters the interior of the chiller through the first vent 11.

[0056] During the ventilation process, the airflow entering from the outside exchanges heat with the internal hot air to reduce the internal temperature. Under the guiding effect of the first flange 31, the hot air enters the ventilation structure from the first vent 11 of the first ventilation member 1, and the airflow flows to the second ventilation member 2. Under the guiding effect of the second flange 32, the airflow flows through the second vent 21 and out of the ventilation structure to the outside of the chiller, completing the ventilation process from the inside to the outside, realizing the air circulation inside and outside the chiller, and improving the heat dissipation effect of the chiller.

[0057] The arrangement of the first flange 31 and the second flange 32 makes it more difficult for water on the outside of the chiller to enter the inside of the chiller, thereby improving the waterproofness of the ventilation structure, and having a certain barrier effect on water vapor or impurities outside the chiller, thereby preventing external water vapor or impurities from entering the chiller and affecting the internal operation of the chiller, thereby providing reliability of the operation inside the chiller.

[0058] Optionally, the first flange 31 extends in the horizontal direction, and the second flange 32 extends in the vertical direction; or, the first flange 31 extends in the vertical direction, and the second flange 32 extends in the horizontal direction.

[0059] The first flange 31 and the second flange 32 may extend in different directions. The first flange 31 may extend in the horizontal direction and the second flange 32 may extend in the vertical direction, or the first flange 31 may extend in the vertical direction and the second flange 32 may extend in the horizontal direction. This application takes the first flange 31 extending in the vertical direction and the second flange 32 extending in the horizontal direction as an example.

[0060] Under the guidance of the second flange 32 extending in the horizontal direction, the outside air enters the ventilation structure from the second vent 21 of the second ventilation member 2 in the horizontal direction, and the airflow reaches the first ventilation member 1. Under the guidance of the first flange 31 extending in the vertical direction, the hot air inside the chiller enters the ventilation structure from the first vent 11 of the first ventilation member 1 in the vertical direction. Under the guidance of the first flange 31 extending in the vertical direction, the hot air inside the chiller enters the ventilation structure from the first vent 11 of the first ventilation member 1 in the vertical direction, and the airflow reaches the second ventilation member 2. Under the guidance of the second flange 32 extending in the horizontal direction, the hot air flows through the second vent 21 in the horizontal direction, flows out of the ventilation structure and reaches the outside of the chiller, completing the ventilation process from inside to outside, realizing the air circulation inside and outside the chiller, and improving the heat dissipation effect of the chiller.

[0061] The first vent and the second vent are in the shape of a rectangle, the first flange extends vertically along the wide side of the rectangle, and the second flange extends horizontally along the long side of the rectangle.

[0062] Optionally, the second flange 32 includes an upper flange 321 and a lower flange 322, the upper flange 321 is arranged on the upper side of the second vent 21 and extends in the horizontal direction; the lower flange 322 is arranged on the lower side of the second vent 21, opposite to the upper flange 321, and extends in the horizontal direction.

[0063] The upper flange 321 and the lower flange 322 guide the airflow entering and exiting the second vent 21. The upper flange 321 and the lower flange 322 are relatively arranged and extend in the horizontal direction, so that when the airflow enters and exits the second vent 21, it will enter and exit along the upper flange 321 or the lower flange 322 extending in the horizontal direction, making the airflow flow smoother, increasing the airflow flow rate, and improving the heat dissipation effect.

[0064] Alternatively, if Figure 6 and Figure 8 As shown, the first flange 31 includes a first sub-flange 311 and a second sub-flange 312. The first sub-flange 311 contacts the ends of the upper flange 321 and the lower flange 322 on one side of the first vent 11; the second sub-flange 312 is arranged opposite to the first sub-flange 311, and contacts the ends of the upper flange 321 and the lower flange 322 on the other side of the first vent 11.

[0065] When external air is about to enter the ventilation structure, the setting of the first sub-flange 311 and the second sub-flange 312 allows the air to enter the ventilation structure under the guidance of the upper flange 321 and the lower flange 322. The air flows in the ventilation structure, passes through the first ventilation port 11 under the guidance of the first sub-flange 311 and the second sub-flange 312 of the two adjacent first ventilation ports 11, and then flows out of the ventilation structure into the interior.

[0066] The first sub-flange 311 and the second sub-flange 312 are respectively in contact with the ends of the upper flange 321 and the lower flange 322 of the two adjacent first vents 11. The first sub-flange 311, the second sub-flange 312, the upper flange 321 and the lower flange 322 cooperate with each other to improve the waterproofness of the ventilation structure, and play a certain blocking role on water vapor or impurities outside the chiller, which can prevent external water vapor or impurities from entering the chiller, avoid affecting the internal operation of the chiller, and thus provide reliability of the operation inside the chiller.

[0067] Alternatively, if Figure 8 As shown, a gap 33 is provided between the second flange 32 and the first ventilation element 1 .

[0068] The above embodiment mentioned that the second flange 32 includes an upper flange 321 and a lower flange 322, that is, there is a gap 33 between the upper flange 321 and the lower flange 322 and the first ventilation member 1, and there are two ventilation paths for external air. One is to flow into the ventilation structure along the gap 33 between the upper flange 321 and the lower flange 322 and the first ventilation member 1 respectively, and the other is to enter the ventilation structure along the two ends of the second vent 21 where the second flange 32 is not set, and the airflow flows to the first vent 11, flows out of the ventilation structure, and enters the interior of the chiller. During the ventilation process, the airflow entering from the outside exchanges heat with the internal hot air to reduce the internal temperature. The hot air enters the ventilation structure from the first vent 11, and then flows out of the ventilation structure from the gap 33 between the second flange 32 and the first ventilation member 1, or flows out of the ventilation structure from the two ends of the second vent 21 where the second flange 32 is not set to reach the outside of the chiller, completing the ventilation process from inside to outside, realizing the air circulation inside and outside the chiller, and improving the heat dissipation effect of the chiller.

[0069] Optionally, the first flange 31 is in contact with the second ventilation member 2 .

[0070] The outside air enters the ventilation structure through the gap 33 or the two ends of the second ventilation opening 21 in the length direction, and the first flange 31 contacts the second ventilation member 2, so the airflow flows to the first ventilation opening 11 along the two ends of the width direction of the first ventilation opening 11, and flows out of the ventilation structure. The internal hot air flows to the first ventilation opening 11 from the two ends of the width direction of the first ventilation opening 11, flows into the ventilation structure, and flows out of the ventilation structure from the gap 33 or the two ends of the length direction of the second ventilation opening 21, realizing the ventilation process and realizing the air circulation inside and outside the chiller.

[0071] Alternatively, if Figure 1 and Figure 5 As shown, there are multiple first vents 11 and second vents 21, and the first vents 11 and second vents 21 are cross-distributed along the same horizontal direction.

[0072] The first vent 11 and the second vent 21 are cross-distributed, the first vent 11 is relatively arranged between the two second vents 21, and the second vent 21 is relatively arranged between the two first vents 11. This arrangement ensures that no matter whether the outside air enters the inside of the chiller or the internal hot air flows to the outside of the chiller, the airflow path is shorter, and the airflow enters the ventilation structure along the second vent 21 from the outside, and then flows out of the ventilation structure from the adjacent first vent 11. The airflow path is relatively short, which improves the ventilation efficiency inside and outside the chiller, and the number of the first vent 11 and the second vent 21 are both multiple, which increases the ventilation volume inside and outside the chiller. Overall, the heat dissipation effect of the chiller is improved.

[0073] The first vents include multiple rows and columns, and the second vents include multiple rows and columns. The row and column positions of the first vents and the second vents correspond to each other. The first vents in each row are arranged at the intervals of the second vents in the corresponding row. The first vents are in two columns, and the second vents are in three columns.

[0074] Alternatively, if Fig.10 and Fig.11 As shown, the ventilation structure also includes a fixing member 4, which is circumferentially arranged on the second ventilation member 2. The fixing member 4 is provided with a limiting portion 41, and the second ventilation member 2 is provided with a limiting matching portion 22. The limiting portion 41 and the limiting matching portion 22 are clamped together to fix the second ventilation member 2 to the fixing member 4.

[0075] The fixing member 4 is provided with a limiting portion 41, and the second ventilation member 2 is provided with a limiting matching portion 22. The limiting portion 41 is a bayonet, and the limiting matching portion 22 is a snap-fit ​​structure, which is snapped into the bayonet to fix the second ventilation member 2 and the fixing member 4. Alternatively, the limiting matching portion 22 is a bayonet, and the limiting portion 41 is a snap-fit ​​structure, which is snapped into the bayonet to fix the second ventilation member 2 and the fixing member 4. The snap-fit ​​structure can be a claw or a buckle. The present application takes the limiting portion 41 as a bayonet and the limiting matching portion 22 as a claw as an example, and the claw cooperates with the bayonet to fix the second ventilation member 2 to the fixing member 4. The number of limiting portions 41 can be one or more, and correspondingly, the number of limiting matching portions 22 can be one or more. In the present application, the number of limiting portions 41 is two, and the number of limiting matching portions 22 is also two as an example.

[0076] Alternatively, if Fig. 9 As shown, the first ventilation member 1 is provided with a third flange 12 , which is arranged toward the second ventilation member 2 and supported on the upper flange 321 at the top end of the second ventilation member 2 to fix the first ventilation member 1 .

[0077] The setting of the third flange 12 enables the multiple upper flanges 321 at the top of the second ventilation member 2 to support the first ventilation member 1. The first ventilation member 1 is supported on the second ventilation member 2, and the second ventilation member 2 is fixed to the fixing member 4, so that the structure of the entire ventilation structure is stable, which is conducive to the long-term operation of the ventilation structure.

[0078] An embodiment of the present disclosure provides a chiller, comprising a ventilation structure as described in any one of the above embodiments.

[0079] The chiller provided in the embodiment of the second aspect of the present application includes the ventilation structure described in any one of the embodiments of the first aspect, and thus has all the beneficial effects of the ventilation structure described in any one of the embodiments of the first aspect, which will not be repeated here.

[0080] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them.
