Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and specifically provides a fan and a control method, device and medium thereof. Background Art

[0002] Fans are commonly used household refrigeration equipment. Compared with air conditioners that cool large spaces, fans can cool local spaces and achieve significant energy savings.

[0003] Some fans in the prior art are provided with cooling structures, but these cooling structures can usually only exchange heat with a small part of the air in the fan housing, or only a small area can exchange heat with the air in the fan housing, which results in poor cooling effect of the fans in the prior art. At the same time, the cooling intensity of these fans can be adjusted in a small range and may not meet the expectations of users.

[0004] Accordingly, the art needs to provide a new technical solution to solve the above problems. Summary of the invention

[0005] In order to at least partially overcome the above-mentioned defects, the present invention is proposed. Specifically, the present invention provides a fan and a control method, device and medium thereof that can at least partially solve the technical problems of poor cooling effect of the fan and small adjustable range of cooling intensity.

[0006] A first aspect of the present invention provides a control method for a fan, the fan comprising: a shell having an air inlet and an air outlet; an air guide member disposed in the shell and located between the air inlet and the air outlet; a refrigeration member connected to the shell, wherein the refrigeration member has a cavity for accommodating a refrigeration medium and a through hole allowing air to pass through, so that when the air guide member guides the air flow, the air can pass through the through hole and is thereby cooled by the refrigeration medium; and a storage member for storing a cooling medium capable of absorbing the heat of the refrigeration medium; the control method comprising: obtaining a refrigeration intensity adjustment instruction; and selectively adjusting the opening of the through hole, the position of the refrigeration member and / or the running path of the refrigeration medium according to the refrigeration intensity adjustment instruction.

[0007] The cooling part of the fan is provided with a through hole for allowing air to pass through, so that the heat exchange between the fan and the air is more complete, and a better cooling effect is achieved. At the same time, the above three adjustment methods can all adjust the cooling intensity of the fan, but the specific adjustment effects that can be achieved are slightly different. By selectively using one or more of the three adjustment methods, a wider range of adjustment and more refined adjustment of the cooling intensity can be sought, thereby better meeting the needs of users.

[0008] In a technical solution of the above control method, adjusting the running path of the refrigerant medium includes: blocking the running path of part of the refrigerant medium in the cavity so that the heat of the part of the refrigerant medium cannot be absorbed by the cooling medium.

[0009] Through such a structure, a possible visual method of adjusting the running path of the refrigerant medium is provided. Compared with other methods of adjusting the running path of the refrigerant medium, directly blocking part of the running path of the refrigerant medium has lower implementation cost and is easier to control.

[0010] In a technical solution of the above control method, the interior of the cavity is divided into a plurality of areas, a valve is provided in each area, and adjusting the running path of the refrigerant medium specifically includes: adjusting the open / closed state of the valve.

[0011] In a technical solution of the above control method, adjusting the position of the refrigeration component includes: translating and / or rotating the refrigeration component to change the ratio between the air flow entering the through hole and the air flow entering the shell.

[0012] Through such a configuration, a possible way of adjusting the position of the refrigeration component is provided. It is understandable that the refrigeration intensity adjustment range that can be achieved by adjusting the opening of the through hole or adjusting the operating parameters of the refrigeration component is limited by the structure of the refrigeration component itself, and adjusting the position of the refrigeration component in the above manner can make the refrigeration intensity adjustment range break through this limitation and obtain a larger adjustment range.

[0013] In a technical solution of the above control method, the through holes include multiple ones, and adjusting the position of the refrigeration component includes: translating and / or rotating the refrigeration component so that: when the air guide component guides the air flow, part of the air passes through at least two through holes.

[0014] This configuration provides another possible way to adjust the position of the refrigeration component. Adjusting the position of the refrigeration component in this way can significantly increase the refrigeration intensity in a certain area, thereby meeting the user's rapid and extreme demand.

[0015] In a technical solution of the above-mentioned control method, the refrigeration component includes: a main body portion, the through hole is arranged in the main body portion; and an extension portion, the extension portion extends from the main body portion to the inside of the storage component; wherein, the main body portion and the extension portion both have the cavity, and the cavities of the main body portion and the extension portion are connected; adjusting the running path of the refrigeration medium includes: adjusting the connection state between the cavity at the main body portion and the cavity at the extension portion.

[0016] In a technical solution of the above control method, the storage element is arranged on a side of the main body away from the direction of gravity, and the refrigerant medium is arranged to absorb heat and convert from liquid to gas when exchanging heat with air, and to release heat and convert from gas to liquid when exchanging heat with the cooling medium; adjusting the position of the refrigeration element includes: synchronously adjusting the positions of the refrigeration element and the storage element.

[0017] A second aspect of the present invention provides a fan, comprising a controller, wherein the controller is configured to execute the control method as described in any of the above technical solutions.

[0018] A third aspect of the present invention provides a computer device, comprising a control module, wherein the control module is configured to execute the control method as described in any of the above technical solutions.

[0019] A fourth aspect of the present invention provides a computer-readable storage medium, which is suitable for storing multiple program codes, and the program codes are suitable for being loaded and run by a processor to execute the control method described in any of the above technical solutions.

[0020] It can be understood that the fan, the computer device and the computer-readable storage medium have all the technical effects of any of the control methods described above, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0030] An embodiment of the present invention provides a method for controlling a fan. The structure of the fan targeted by the control method will be described below.

[0031] Figure 1 is a side view of a fan according to an embodiment of the present invention, Figure 2 yes Figure 1 Cross-sectional view of the fan in . Figure 1-Figure 2 The fan of this embodiment includes a shell 1, an air guide member 2, a refrigeration member 3 and a storage member 4.

[0032] The shell 1 has an air inlet 11 and an air outlet 12. In this example, the shell 1 is roughly in a cubic shape. The air inlet 11 and the air outlet 12 are respectively arranged on two opposite side walls of the shell 1. However, it can be understood that the shell 1 can have any suitable shape, and the air inlet 11 and the air outlet 12 can include one or more. The air inlet 11 and the air outlet 12 can be arranged at any suitable position of the shell 1. When the air inlet 11 includes multiple air inlets, the multiple air inlets 11 can be arranged on the same side of the shell 1, or on different sides of the shell 1. The same is true for the air outlet 12. Technical personnel in this field can make a selection according to actual needs.

[0033] The air guide 2 is arranged on the shell 1 and is located between the air inlet 11 and the air outlet 12. In actual use, it can guide the airflow to enter the shell 1 from the air inlet 11 and blow it out from the air outlet 12. The air guide 2 can be, for example, a cross-flow fan, an axial flow fan or other fan commonly used in the art. Those skilled in the art can select a suitable type of fan according to the positions of the air inlet 11 and the air outlet 12, and can determine the power parameters of the fan according to actual use requirements. Preferably, the air inlet 11 and the air outlet 12 can be arranged on the opposite side walls of the shell 1, and a cross-flow fan is used as the air guide 2 to reduce the wind resistance of the air during the flow.

[0034] The refrigeration element 3 is connected to the housing 1 , and has a through hole 31 for allowing air to pass through. When the air guide 2 guides the air flow, the air can pass through the through hole 31 and thus be cooled by the refrigeration element 3 .

[0035] It is understandable that in the prior art, in order to avoid affecting the air flow, the refrigeration structure is usually arranged parallel to the air flow direction, or is arranged perpendicular to the air flow direction only in a small range. However, in these arrangements, only a small part of the air flowing through the surface of the refrigeration structure can exchange heat with the refrigeration structure, resulting in a poor refrigeration effect. In this example, the refrigeration element 3 has a through hole 31 that allows air to pass through. The air can pass through the through hole and is therefore cooled by the refrigeration element 3, thereby increasing the heat exchange area between the air and the refrigeration element 3 and obtaining a better refrigeration effect.

[0036] Furthermore, the refrigeration element 3 also has a cavity for accommodating a refrigeration medium, and the storage element 4 is used to store a cooling medium that absorbs the heat of the refrigeration medium. The refrigeration medium can exchange heat with the air through the portion of the refrigeration element 3 facing the air, thereby cooling the air. In this process, the refrigeration medium will absorb the heat of the air, and this part of the heat can be absorbed by the cooling medium stored in the storage element 4, so that the refrigeration medium can always maintain its refrigeration capacity. Compared with other refrigeration structures in the prior art, such as semiconductor refrigeration structures, the refrigeration element 3 of this example can save energy.

[0037] In this example, the reason why both the refrigeration medium and the cooling medium are set is that the medium that exchanges heat with the air needs to have a sufficiently high heat exchange efficiency to obtain the desired refrigeration effect, and it is necessary to always maintain a low temperature to achieve continuous refrigeration. The medium whose heat exchange efficiency meets this requirement is usually more expensive and may include substances that are not suitable for direct contact with users (such as some chemical raw materials, etc.), and it is difficult for users to continuously supply low-temperature medium during use.

[0038] In the case where both the refrigeration medium and the cooling medium are provided at the same time, the refrigeration medium only needs to have a sufficiently high heat exchange efficiency. The user can absorb the heat of the refrigeration medium by continuously providing a low-temperature cooling medium to ensure its continuous cooling capacity. There is no requirement for the heat exchange efficiency of the cooling medium. Common media in daily life such as water, ice, and ice crystals can be used as cooling media. It is easy for users to continuously provide a low-temperature cooling medium.

[0039] In this example, those skilled in the art can select a medium whose heat exchange efficiency meets the requirements as the refrigeration medium according to the actual refrigeration requirements, and there is no limitation on this.

[0040] The refrigeration component 3 may have any suitable structural form. For example, a part of the structure of the refrigeration component 3 may be a plate-shaped structure, a cylindrical structure, a ring-shaped structure, etc., and the refrigeration component 3 may have multiple of the above structural forms at the same time. The refrigeration component 3 may include one or more refrigeration components. When the refrigeration component 3 includes multiple refrigeration components, the structural forms of the multiple refrigeration components 3 may be the same or different, and those skilled in the art may select according to actual needs. Compared with other structures, the refrigeration component 3 with a plate-shaped structure has a larger refrigeration area under the premise of the same volume.

[0041] The refrigeration element 3 can be connected to any suitable position of the shell 1, for example, the refrigeration element 3 can be connected to the inner wall of the shell 1, or to other structures connected to the shell 1. The refrigeration element 3 can be connected to only one inner wall of the shell 1, or to multiple inner walls at the same time. In the case where the refrigeration element 3 includes multiple refrigeration elements, the multiple refrigeration elements 3 can be connected to the same wall of the shell 1, or can be connected to different walls of the shell 1 (including the inner wall and the outer wall) respectively. Those skilled in the art can set the refrigeration element 3 at any suitable position according to actual needs, as long as it can cool the air flowing out of the shell 1.

[0042] The through hole 31 can have any suitable structural form. For example, the cross-sectional shape of the through hole 31 can be rectangular, circular, triangular or even irregular. The through hole 31 can be a straight hole, a curved hole or even an irregular hole, as long as the air can pass through it. The through hole 31 can be set at any suitable position of the refrigeration component 3. The through hole 31 can include one or more. In the case where the through hole 31 includes multiple through holes, the shape, size, extension direction, etc. of the through hole 31 can be the same, different or not completely the same. As described above, the structure of the refrigeration component 3 can be a structure with a hollow part such as an annular structure or a cylindrical structure. In this case, the hollow structure of the refrigeration component 3 can be used as a through hole 31. On this basis, other through holes 31 may not be set, or other through holes 31 may continue to be set. Those skilled in the art can flexibly set it according to actual use requirements.

[0043] The storage element 4 may be any suitable container, and the storage element 4 may be disposed inside the housing 1 or outside the housing 1. In the case where the storage element 4 is disposed inside the housing 1, the storage element 4 may be slidably connected to the housing 1, so that the storage element 4 can be at least partially removed from the housing 1, so as to facilitate the user to add cooling medium to the storage element 4 or replace the cooling medium in the storage element 4. Alternatively, in the case where the storage element 4 is disposed inside the housing 1, one or more walls of the housing 1 may be configured as one or more walls of the storage element 4, and these walls may be provided with openings, through which the user can add cooling medium to the storage element 4 or replace the cooling medium in the storage element 4.

[0044] The storage element 4 may include one or more storage elements. When the refrigeration element 3 includes more than one storage element, the more than one refrigeration element 3 may be connected to the same storage element 4, or may be connected to more than one storage element 4. Those skilled in the art may set the storage element 4 according to the specific setting mode of the refrigeration element 3, and there is no limitation on this. The cooling medium stored in the storage element 4 may include any suitable medium, such as water, ice, ice crystals, dry ice, etc., and the user may select and add it to the storage element 4.

[0045] The refrigeration element 3 can be connected to the storage element 4 in any suitable manner, as long as the heat of the refrigerant medium can be absorbed by the cooling medium. For example, part of the structure of the refrigeration element 3 can extend into the storage element 4 and contact the cooling medium of the storage element 4, or the refrigeration element 3 can have an opening, and the refrigeration element 3 can cover the opening so that the cooling medium inside the storage element 4 can directly contact the refrigeration element 3. Alternatively, the storage element 4 can be provided with a pump and a cooling medium circulation pipeline, and the cooling medium circulation pipeline can be arranged in close contact with the refrigeration element 3, and the cooling medium can enter the cooling medium pipeline under the drive of the pump and absorb the heat generated by the refrigeration element 3. Those skilled in the art can reasonably select the connection method between the refrigeration element 3 and the storage element 4 according to the specific structure of the refrigeration element 3 actually selected, which will not be repeated here.

[0046] In a possible implementation, the cavity of the refrigeration element 3 can be arranged around the through hole 31 so that the refrigerant medium exchanges heat with the air in the through hole 31 through the inner wall of the through hole 31. With such a configuration, the heat exchange area between the refrigerant medium and the air is significantly increased, thereby achieving a better refrigeration effect. Obviously, the cavity of the refrigeration element 3 can also be arranged in other ways, as long as the refrigerant medium in the cavity can achieve heat exchange with the air and the cooling medium.

[0047] As described above, there may be a plurality of through holes 31. In this case, the cavity of the refrigeration element 3 may be disposed around each through hole 31, thereby further increasing the heat exchange area between the refrigeration medium and the air.

[0048] In one possible implementation, refer to Figure 3 and Figure 4The refrigeration element 3 may include a main body 32 and an extension 33, the through hole 31 may be provided in the main body 32, and the extension 33 may extend from the main body 32 to the inside of the storage element 4. The main body 32 and the extension 33 both have the above-mentioned cavity, and the cavities of the main body 32 and the extension 33 are connected, so that the refrigerant medium at the main body 32 can move to the extension 33 and exchange heat with the cooling medium stored in the storage element 4 after heat exchange, and then move to the main body 32 again to exchange heat with the air after heat exchange, so that it can continue to cool.

[0049] Through such a configuration, a possible structural form of the refrigeration component 3 is provided. In this embodiment, the refrigerant medium in the main body 32 mainly exchanges heat with the air, while the refrigerant medium at the extension portion 33 mainly exchanges heat with the cooling medium. The refrigerant medium can be circulated between the main body 32 and the extension portion 33 in an appropriate manner, thereby achieving a better refrigeration effect.

[0050] In a possible embodiment, the main body 32 may be a plate-like structure or a cylindrical structure. In the case where the main body 32 is a plate-like structure, it may be a flat plate-like structure or an arc-shaped plate-like structure. The main body 32 may be located on one side of the air guide 2. This arrangement may increase the heat exchange area between the main body 32 and the air. In the case where the main body 32 is a cylindrical structure, the air guide 2 may be arranged at the hollow portion in the cylindrical structure. This arrangement may allow the air to exchange heat with the cooling medium in the main body 32 multiple times when the air guide 2 guides the air flow, thereby improving the cooling effect. Obviously, the structural form of the main body 32 is not limited thereto. Those skilled in the art may also arrange the main body 32 into any other suitable structure according to the specific spatial layout inside the housing 1 and the air flow path.

[0051] In a possible implementation, still referring to Figure 3 and Figure 4 The through holes 31 may include a plurality of through holes 31, and the plurality of through holes 31 may be distributed in a grid shape in the main body 32. With such a configuration, the plurality of through holes 31 will be able to evenly distribute the air, thereby further increasing the heat exchange area between the refrigerant medium and the air, and obtaining a better refrigeration effect. In addition to the grid-like distribution, the plurality of through holes 31 may also be distributed in the main body 32 in any other suitable manner, such as a honeycomb shape, a concentric circle shape, or the like.

[0052] In one possible implementation, refer to Figure 2In the case where the main body 32 is a plate-like structure, the extension direction of the main body 32 is perpendicular to the air flow direction in the shell, that is, the main body 32 is arranged to face the wind. This arrangement can maximize the cooling range of the main body 32, thereby obtaining a better cooling effect. Moreover, since a plurality of through holes 31 are arranged on the main body 32, this arrangement to face the wind does not reduce the air volume. Obviously, the extension direction of the main body 32 can also form an acute angle with the air flow direction in the shell 1, or be nearly parallel, but this will reduce the cooling effect.

[0053] In a possible implementation, still referring to Figure 2 The main body 32 can be located between the air guide 2 and the air inlet 11. The main body 32 is arranged here so that the air can fully exchange heat with the refrigerant before leaving the housing 1 from the air outlet 12, thereby obtaining a better cooling effect. Obviously, the arrangement of the main body 32 is not limited to this, for example, it can also be arranged between the air guide 2 and the air outlet 12, and those skilled in the art can freely choose according to actual needs.

[0054] In a possible implementation, still referring to Figure 2 , the projection of the main body 32 on the plane where the air inlet 11 is located can cover the air inlet 11. Through such a structure, almost all of the air flowing through the air inlet 11 will pass through the through hole 31 of the main body 32 and thus be cooled, thereby achieving a better cooling effect.

[0055] In one possible implementation, refer to Figure 3 and Figure 4 The storage element 4 can be arranged on the side of the main body 32 away from the gravity direction, that is, the extension portion 33 will eventually extend to the side of the main body 32 away from the gravity direction. In this case, the refrigerant can be arranged to absorb heat and convert from liquid to gas when exchanging heat with air, and to release heat and convert from gas to liquid when exchanging heat with the cooling medium.

[0056] Therefore, after the refrigerant medium in the main body 32 exchanges heat with the air and is converted into gas, it will automatically diffuse to the extension part 33 and exchange heat with the cooling medium, and the liquefied refrigerant medium after heat exchange with the cooling medium will automatically flow back to the main body 32, realizing the natural circulation of the refrigerant medium.

[0057] Obviously, in other possible implementations, the refrigerant medium may not undergo phase change during the heat exchange process. In these implementations, the refrigerant medium can be forced to circulate by a driving device such as a pump to ensure that the refrigerant medium can continue to cool. The advantages of these implementations are that the circulation of the refrigerant medium is more efficient than natural circulation. The disadvantage is that it will bring greater energy loss and noise.

[0058] In a possible embodiment, the refrigerant medium may include a superconducting liquid. The refrigerant medium may include a superconducting liquid. The superconducting liquid is a liquid that can be prepared from chemical raw materials. Compared with conventional liquid media, the superconducting liquid has a higher heat exchange efficiency, thereby being able to obtain a better refrigeration effect. The physical properties such as the boiling point of the superconducting liquid can be regulated by adjusting the type of raw materials and the principle ratio. Those skilled in the art can select appropriate raw materials to set the superconducting liquid according to actual refrigeration needs, and there is no limitation on this. In a possible embodiment, the material of the main body 32 and the extension 33 can also be a material with high heat exchange efficiency, or even a super thermal conductive material, so as to further obtain a better refrigeration effect.

[0059] Furthermore, in the case where the refrigerant medium includes a superconducting liquid, the interior of the cavities of the main body 32 and the extension portion 33 can be in a vacuum state, so that the refrigerant medium will diffuse rapidly to the extension portion 33 due to the gas pressure after being converted into a gaseous state, and the refrigerant medium at the extension portion 33 will also flow rapidly to the main body 32 under the action of the temperature difference after being converted into a liquid state, thereby improving the natural circulation efficiency of the refrigerant medium.

[0060] In a possible implementation, still referring to Figure 3 and Figure 4 The extension portion 33 may specifically include a first extension section 331 connected to the main body portion 32, and at least one second extension section 332 connected to the first extension section 331. The storage element 4 may have an opening facing the gravity direction, the first extension section 351 may cover the opening, and the second extension section 332 may extend through the opening to the interior of the storage element 4. In this example, the first extension section 331 and the storage element 4 may be sealed to prevent the cooling medium from flowing into the interior of the housing 1 from the opening.

[0061] In this case, the cooling medium in the storage element 4 will be gathered to the opening due to gravity, so that the surfaces of the first extension section 331 and the second extension section 332 facing the storage element can exchange heat with the cooling medium, significantly increasing the heat exchange area between the cooling medium and the cooling medium, and achieving a better cooling effect. Obviously, those skilled in the art can also use other methods to set the extension part 33 and the storage element 4 according to actual needs. For example, the storage element 4 can be provided with no opening, and the extension part 33 can pass through a wall of the storage element 4 and extend to the inside of the storage element 4.

[0062] The fan control method provided by the present invention will be described below. The fan control method can be applied to the fan described in any of the above embodiments to adjust the cooling intensity thereof.

[0063] Reference Figure 5 , the fan control method provided by the embodiment of the present invention includes:

[0064] Step S501: Under the fan running state, obtaining a cooling intensity adjustment instruction;

[0065] Step S502: selectively adjusting the opening of the through hole, the position of the refrigeration component and / or the running path of the refrigeration medium according to the refrigeration intensity adjustment instruction.

[0066] In step S501, the cooling intensity adjustment instruction may be any instruction indicating the action of cooling intensity adjustment, or an instruction involving the action of cooling intensity adjustment during execution. In some cases, in addition to indicating the action of cooling intensity adjustment, the cooling intensity adjustment instruction may also indicate other actions, such as air volume and wind speed adjustment.

[0067] Further, in step S501, the refrigeration intensity adjustment instruction may be obtained in any suitable manner, for example, the refrigeration intensity adjustment instruction input by the user may be received. For another example, the refrigeration intensity adjustment instruction may be generated by parsing other instructions input by the user, such as the user inputting the desired temperature, and the refrigeration intensity adjustment instruction is generated according to the user's desired temperature and the current ambient temperature. For another example, the current ambient temperature may be obtained, and the refrigeration intensity adjustment instruction may be automatically generated according to the current ambient temperature and a pre-set control logic. Those skilled in the art may make settings according to actual needs, and there is no limitation to this.

[0068] In step S502, the opening of the through hole 31, the position of the refrigeration component 3 and / or the running path of the refrigeration medium can be selectively adjusted according to the refrigeration intensity adjustment instruction to adjust the refrigeration intensity of the fan to be compatible with the refrigeration intensity adjustment instruction.

[0069] As an example, a mapping table between refrigeration intensity and through-hole opening, refrigeration medium running path, and refrigeration component position may be prepared in advance, and after obtaining a refrigeration intensity adjustment instruction, the adjustment may be completed according to the mapping table.

[0070] The above three adjustment methods can all adjust the cooling intensity, but the specific adjustment effects that can be achieved are slightly different. By selectively using one or more of the three adjustment methods, it is possible to seek fine adjustment of the cooling intensity, thereby better meeting the needs of users. When faced with different cooling intensity adjustment instructions, the specific adjustment methods to be selected for adjustment can be determined by those skilled in the art based on the specific adjustment effects that can be achieved by the above three adjustment methods in the targeted fans. The relevant parts below will also give some examples, which will not be repeated here.

[0071] The following will describe the cooling intensity adjustment effects that can be achieved by the above three adjustment methods respectively.

[0072] Regarding adjusting the opening of through hole 31:

[0073] It can be understood that when the opening of the through hole 31 changes, the amount of air allowed to pass through the through hole 31 will change, resulting in a change in the contact area between the refrigeration component 3 and the air, which in turn causes a change in the refrigeration intensity. At the same time, when the opening of the through hole 31 changes, it will also affect the wind resistance of the fan to a certain extent, resulting in changes in the wind speed, wind volume, etc. of the fan. Therefore, when the refrigeration intensity adjustment instruction indicates the adjustment of the refrigeration intensity while also indicating the adjustment of the wind volume, wind speed, etc., it can be preferred to adjust the opening of the through hole 31.

[0074] Adjusting the opening of the through hole 31 here may refer to continuously adjusting the opening of the through hole 31 between 0 and the maximum opening, or may refer to jumpily adjusting the opening of the through hole 31 between 0 and the maximum opening, or between 0, the maximum opening, and one or more openings within the range of 0 and the maximum opening. In the case where there are multiple through holes 31, the openings of the multiple through holes 31 may be adjusted synchronously, or the opening of each through hole 31 may be adjusted separately.

[0075] As a way to adjust the opening of the through hole 31, an opening adjustment mechanism may be provided at the through hole 31, which may include a movable baffle structure and a driving structure capable of driving the baffle structure to move to adjust the opening, and the opening of the through hole 31 may be adjusted by sending instructions to the opening adjustment mechanism. Obviously, those skilled in the art may also adjust the opening of the through hole 31 by adopting other structures, and may specify a corresponding control method according to the specific structure adopted.

[0076] About adjusting the running path of the refrigeration medium:

[0077] It is understandable that the refrigerant medium that exchanges heat with the air will absorb the heat of the air during cooling. After absorbing the heat, this part of the refrigerant medium needs to run to a position close to the storage element 4 so that the heat is absorbed by the cooling medium before cooling can be performed again. That is, the refrigerant medium needs to circulate between the position where it exchanges heat with the air and the position where it exchanges heat with the cooling medium.

[0078] Adjusting the running path of the refrigerant medium can partially disrupt the above cycle, causing a part of the refrigerant medium to lose its refrigeration capacity due to the inability to exchange heat with the cooling medium, or reducing the heat exchange efficiency with the air due to the reduced efficiency of heat exchange with the cooling medium, ultimately causing a change in the refrigeration intensity.

[0079] About adjusting the position of refrigeration unit 3:

[0080] It is understandable that when the position of the refrigeration element 3 changes, the refrigeration range of the refrigeration element 3, the contact area between the refrigeration part and the air, etc. will change accordingly, thereby causing the refrigeration intensity to change. This adjustment method will hardly change the air volume of the fan while adjusting the refrigeration intensity.

[0081] Further, it can be understood that, when the position of the refrigeration component 3 remains unchanged, whether it is adjusting the opening of the through hole 31 or adjusting the running path of the refrigerant, the adjustment range that can be achieved is limited by the structure of the refrigeration component 3 itself. This limitation can be overcome to a certain extent by adjusting the position of the refrigeration component 3. For example, when the opening of the through hole 31 is adjusted to the maximum and the various operating parameters of the refrigeration component 3 are adjusted to the highest, the refrigeration component 3 itself reaches the maximum refrigeration intensity. On this basis, if the position of the refrigeration component 3 is adjusted to increase the contact area between the refrigeration component 3 and the air, the refrigeration intensity can be further improved. Combining this adjustment method with the adjustment method described above can seek a larger adjustment range or a more refined adjustment range, thereby better meeting the needs of users.

[0082] As an implementation method of adjusting the position of the refrigeration component 3, a driving mechanism connected to the refrigeration component 3 may be provided, and a command may be sent to the driving mechanism to drive the refrigeration component 3 to move so as to change the position of the refrigeration component 3. Those skilled in the art may reasonably select the driving mechanism and set the range of the position of the refrigeration component 3 to be allowed to be adjusted according to the specific position adjustment method to be implemented, and this is not limited.

[0083] The following will be Figure 1-Figure 4 Taking the fan shown in FIG. 1 as an example, specific implementation methods of the above three adjustment methods are described respectively.

[0084] Regarding the adjustment of the opening of through hole 31:

[0085] In one possible implementation, refer to Figure 2 , the through hole 31 may include multiple through holes 31. In this case, when adjusting the opening of the through hole 31, the opening of the multiple through holes 31 can be adjusted synchronously, for example, the opening of the multiple through holes 31 can be adjusted from 50% to 70%. Alternatively, the through holes 31 can be divided into multiple control groups. When adjusting the opening of the through holes 31, the opening of the through holes 31 in each group can be adjusted synchronously, and the opening of the through holes 31 between different groups can be adjusted separately. Alternatively, the opening of each through hole 31 can also be controlled separately. Those skilled in the art can reasonably select the control method according to actual use requirements, which will not be repeated here.

[0086] In a possible embodiment, the opening adjustment of the through hole 31 may be associated with the adjustment of the running path of the refrigerant medium. For example, after adjusting the running path of the refrigerant medium, the refrigerant medium in the area where some through holes are located may lose its refrigeration capacity, so the opening of the through hole 31 in this area can be synchronously adjusted to 0.

[0087] In a possible implementation, the opening adjustment of the through holes 31 may also be associated with the position adjustment of the refrigeration component 3. For example, some through holes 31 may no longer have air flowing through them due to the adjustment of the position of the refrigeration component 3. In this case, these through holes 31 may be synchronously adjusted to have an opening of 0.

[0088] About adjusting the running path of the refrigeration medium:

[0089] In a possible implementation, adjusting the running path of the refrigerant medium includes: blocking a portion of the running path of the refrigerant medium in the cavity so that the heat of the portion of the refrigerant medium cannot be absorbed by the cooling medium. Compared with other methods of adjusting the running path of the refrigerant medium described above, directly blocking a portion of the running path of the refrigerant medium has lower implementation costs and is easier to control.

[0090] In a possible implementation, the interior of the cavity of the refrigeration component 3 can be divided into multiple areas, each of which can be provided with a valve, and the running path of part of the refrigeration medium can be blocked by adjusting the opening and closing states of these valves. Through such a configuration, a possible way of blocking the running path of the refrigeration medium is provided.

[0091] In a possible implementation, as described above, the refrigeration element 3 may include a body portion 32 and an extension portion 33. The through hole 31 is provided in the body portion 32, and the extension portion 33 extends from the body portion 32 to the inside of the storage element 4. The body portion 32 and the extension portion 33 both have cavities, and the cavities of the body portion 32 and the extension portion 33 are connected.

[0092] In this embodiment, the refrigerant medium at the main body 32 mainly exchanges heat with the air, while the refrigerant medium at the extension 33 mainly exchanges heat with the cooling medium. In actual operation, the refrigerant medium needs to circulate between the main body 32 and the extension 33. In this case, adjusting the running path of the refrigerant medium may include adjusting the connection state between the main body 32 and the extension 33, for example, completely or partially blocking the main body 32 and the extension 33, so that the refrigerant medium will not be able to complete the cycle or the cycle efficiency will be reduced, resulting in a change in the refrigeration intensity.

[0093] About adjusting the position of refrigeration unit 3:

[0094] In a possible implementation, the ratio between the air flow entering the through hole 31 and the air flow entering the shell 1 can be changed by translating and / or rotating the refrigeration element 3. As described above, the through hole 31 may include one or more. In the case where the through hole 31 includes more than one, the air flow in the through hole 31 here refers to the total flow of air in the multiple through holes 31. It can be understood that the air passing through the through hole 31 can have a relatively sufficient contact with the refrigeration element 3, so the degree of cooling will be higher than the air that does not pass through the through hole 31. When the ratio between the air flow entering the through hole 31 and the air flow entering the shell 1 changes, it means that the proportion of air passing through the through hole 31 changes, thereby changing the overall cooling intensity.

[0095] by Figure 2 Take the refrigeration element 3 with a middle plate structure as an example. Figure 2 In the position shown in FIG. 1 , the projection range of the refrigeration component 3 on the plane where the air inlet 11 is located completely covers the air inlet 11, and the ratio between the air flow rate entering the through hole 31 and the air flow rate entering the shell 1 is close to 1. If the refrigeration component 3 is translated vertically upward or downward, or the refrigeration component 3 is rotated with the central axis of the shell 1 in the vertical direction as the rotation axis, after the translation and rotation, part of the through holes 31 will no longer face the air inlet, and the flow rate of the part of the through holes 31 will decrease, thereby causing the ratio between the air flow rate in the through holes 31 and the air flow rate entering the shell 1 to change.

[0096] In a possible implementation, the refrigeration element 3 may be translated and / or rotated so that part of the air passes through at least two through holes 31. In this embodiment, the refrigeration element 3 may be configured as, for example, an arc-shaped plate structure, so that at a certain angle, the air passes through two or more through holes 31 of the refrigeration element 3.

[0097] Alternatively, a plurality of refrigeration components 3 may be provided, and adjusting the position of the refrigeration component 3 may include adjusting the relative positions of the plurality of refrigeration components 3 so that part of the air passes through the respective through holes 31 of at least two refrigeration components 3 .

[0098] It is understandable that each time the air passes through a through hole 31, it will fully exchange heat with the refrigerant, and through the above adjustment, part of the air will pass through at least two through holes 31, that is, it will exchange heat with the refrigerant at least twice, thereby increasing the cooling intensity of the part of the air. One advantage of this adjustment method is that it can significantly increase the cooling intensity in a certain area, thereby meeting the user's demand for rapid cooling.

[0099] In a possible embodiment, as described above, the storage element 4 can be arranged on the side of the main body 32 away from the direction of gravity, and the extension portion 33 of the refrigeration element 3 extends to the interior of the storage element 4. The refrigerant medium can be arranged to absorb heat and convert from liquid to gas when exchanging heat with the air, and to release heat and convert from gas to liquid when exchanging heat with the cooling medium. In this case, when adjusting the position of the refrigeration element 3, the positions of the refrigeration element 3 and the storage element 4 can be adjusted synchronously. The synchronous adjustment here means adjusting the positions of the two in a way that there is no relative movement between the two, thereby avoiding the change in the relative position between the refrigeration element 3 and the storage element 4 and causing leakage of the cooling medium in the storage element 4.

[0100] Obviously, in this case, those skilled in the art may also choose to connect the extension part and the storage element 4 in the form of dynamic sealing, etc., so that the position of the refrigeration element 3 can be moved independently without worrying about the leakage of the cooling medium.
