Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular provides a fan. 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 refrigeration structures, but these refrigeration 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 refrigeration effect of the fans in the prior art.

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

[0005] In order to overcome the above-mentioned defects to at least a certain extent, the present invention is proposed. Specifically, the present invention provides a fan that can at least a certain extent solve the technical problem of poor cooling effect of the fan.

[0006] The present invention provides a fan, which includes: a shell having an air inlet and an air outlet; an air guide member, which is arranged on the shell and located between the air inlet and the air outlet; a refrigeration member, which is connected to the shell, and 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 thus cooled by the refrigeration medium; and a storage member, which is used to store a cooling medium that can absorb the heat of the refrigeration medium.

[0007] 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 has a through hole that allows air to pass through, and the air can pass through the through hole and is therefore cooled by the refrigeration element, thereby seeking a larger contact area between the refrigeration element and the air, thereby obtaining a better refrigeration effect.

[0008] On the other hand, the refrigeration medium is used for refrigeration in this example, which is more energy-saving than the refrigeration method used in the prior art.

[0009] In a technical solution of the above-mentioned fan, the cavity is arranged around the through hole so that: the refrigerant medium exchanges heat with the air in the through hole through the inner wall of the through hole.

[0010] With such a structure, the heat exchange area between the refrigerant medium and the air is significantly increased, thereby achieving a better refrigeration effect.

[0011] In one technical solution of the above-mentioned fan, the refrigeration component includes a main body portion, a through hole is arranged in the main body portion; and an extension portion, which is connected to the main body portion and extends 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.

[0012] Such a configuration provides a possible structural form of the refrigeration element.

[0013] In a technical solution of the above-mentioned fan, the through holes include a plurality of through holes, and the plurality of through holes are distributed in the main body in a grid shape.

[0014] With such a structure, the multiple through holes can achieve a uniform flow of air, thereby further increasing the heat exchange area between the refrigerant medium and the air, and obtaining a better refrigeration effect.

[0015] In a technical solution of the above-mentioned fan, when the main body is a plate-shaped structure, the extension direction of the main body is perpendicular to the air flow direction in the shell.

[0016] Through such a structure, the cooling range of the main body can be maximized (without changing the area of ​​the main body), thereby obtaining a better cooling effect.

[0017] In a technical solution of the above-mentioned fan, the main body is located between the air guide member and the air inlet.

[0018] With such a structure, the air can fully exchange heat with the refrigerant medium before leaving the shell from the air outlet, thereby obtaining a better cooling effect.

[0019] In a technical solution of the above-mentioned fan, a projection range of the main body on a plane corresponding to the air inlet covers the air inlet.

[0020] With such a structure, almost all the air flowing through the air inlet will pass through the through holes of the main body and thus be cooled, thereby achieving a better cooling effect.

[0021] In one technical solution of the above-mentioned fan, 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.

[0022] With such a configuration, natural circulation of the refrigerant can be achieved.

[0023] In a technical solution of the above fan, the refrigerant medium includes superconducting liquid.

[0024] With such a configuration, the heat exchange efficiency of the refrigerant can be improved.

[0025] In one technical solution of the above-mentioned fan, the extension portion includes a first extension segment connected to the main body portion, and at least one second extension segment connected to the first extension segment, wherein the storage element has an opening facing the direction of gravity, the first extension segment covers the opening, and the second extension segment extends into the storage element through the opening.

[0026] In this case, the cooling medium in the storage element will gather at the opening due to gravity, so that the surfaces of the first extension section and the second extension section facing the storage element can exchange heat with the cooling medium, which significantly increases the heat exchange area between the refrigerant medium and the cooling medium, and can achieve a better cooling effect.

[0034] 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.

[0035] An embodiment of the present invention provides a fan. 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.

[0036] 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 air inlet 11 and the air outlet 12. 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.

[0037] The air guide 2 is arranged between the air inlet 11 and the air outlet 12, so as to guide the air flow from the air inlet 11 into the housing 1 and blow it out from the air outlet 12. The air guide 2 can be a fan commonly used in the art, such as a cross-flow fan and an axial flow fan. 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 housing 1, and a cross-flow fan is used as the air guide 2 to reduce the wind resistance of the air during the flow.

[0038] 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, at least part of the air will pass through the through hole 31 and thus be cooled by the refrigeration element 3 .

[0039] 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.

[0040] Furthermore, the refrigeration element 3 has a cavity in which a refrigeration medium is arranged. The storage element 4 is used to store a cooling medium that can absorb the heat of the cooling medium. The cooling medium can exchange heat with the air through the portion of the refrigeration element 3 facing the air, thereby cooling the air. At the same time, the cooling medium can also exchange heat with the cooling medium stored in the storage element 4 through the portion of the refrigeration element 3 close to the storage element 4, thereby dissipating the heat absorbed by it to achieve continuous cooling. Compared with other refrigeration structures in the prior art, such as semiconductor refrigeration structures, the refrigeration element 3 of this example can save energy.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] In one possible implementation, refer to Figure 3 and Figure 4 The 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.

[0053] 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.

[0054] 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 of 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.

[0055] 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.

[0056] In one possible implementation, refer to Figure 2 In 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Obviously, in other possible embodiments, the refrigerant medium may not undergo phase change during the heat exchange process. In these embodiments, a driving device such as a pump can be used to force the refrigerant medium to circulate between the main body 32 and the extension portion 33 to ensure that the refrigerant medium can continue to cool. The advantage of these embodiments is that the forced circulation of the refrigerant medium can achieve higher circulation efficiency. The disadvantage is that it will bring greater energy loss and noise.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] Furthermore, it is understandable that under different usage conditions, users have different requirements for the cooling intensity of the fan. In the prior art, the fan usually only has the function of adjusting the air volume (the amount of air blown out from the air outlet per unit time), even for some fans with active cooling function.

[0067] Air volume adjustment can only make the user feel the change of wind intensity, but cannot make the user feel the change of wind temperature. In view of this, the fan in some embodiments provided by the present invention further adds a cooling intensity adjustment function. Some implementation methods of this function will be described below. Those skilled in the art can use any of the following implementation methods alone or in combination to implement the cooling intensity adjustment function.

[0068] In a possible implementation, the through hole 31 may be set to have an adjustable opening. It is understandable that when the opening of the through hole 31 changes, the amount of air allowed to pass through the through hole 31 will change, thereby causing the heat exchange area between the air and the refrigeration element 3 to change, thereby causing the air volume and refrigeration intensity of the fan to change at the same time.

[0069] The adjustable opening here may mean that the opening of the through hole 31 can be linearly adjusted between 0 and the maximum opening, or may mean that the opening of the through hole 31 can be switched 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 all be set to be adjustable, or the openings of only some of the through holes 31 may be set to be adjustable. The openings of the multiple through holes 31 may be set to be adjustable synchronously, or individually, and the ranges of the openings of the multiple through holes 31 that are allowed to be adjusted may be the same or different.

[0070] A suitable mechanical structure may be provided at the through hole 31 to make the opening of the through hole 31 adjustable. For example, a movable baffle structure may be provided at the through hole 31. Alternatively, a mechanical structure may be added to the refrigeration component 3 to make the opening of the through hole 31 adjustable. Those skilled in the art may make the arrangements according to actual needs, which will not be elaborated herein.

[0071] In a possible embodiment, the refrigeration component 3 may include multiple refrigeration components 3, and the refrigeration functions of the multiple refrigeration components 3 can be set to be independently turned on or off. Specifically, the refrigeration function of the refrigeration component 3 can be turned off by blocking the heat exchange between the refrigeration medium and the cooling medium. This blocking can be achieved by setting a valve or other throttling device in the cavity of the refrigeration component 3, or it can be achieved by disconnecting the refrigeration component 3 from the storage component 4. Those skilled in the art can set it according to actual needs.

[0072] In this example, the cooling intensity can be adjusted by adjusting the number of refrigeration parts 3 opened. Compared with the method of adjusting the opening of the through hole 31, this implementation will not cause a change in the air volume while adjusting the cooling intensity. The adjustment of the air volume can be achieved by other methods such as changing the power of the air guide 2, thereby achieving independent adjustment of the cooling intensity and the air volume, and being able to seek a better user experience.

[0073] As another possible implementation, in the case where only one refrigeration element 3 is included, the refrigeration element 3 may include multiple refrigeration partitions, and the refrigeration functions of the multiple refrigeration partitions may be set to be independently turned on or off, thereby achieving a similar effect. The cavity of the refrigeration element 3 may be selected to form multiple refrigeration partitions, and a valve may be set in each partition. When the valve is closed, the refrigeration medium in the partition cannot move and therefore cannot exchange heat with the cooling medium, thereby losing the refrigeration function.

[0074] Obviously, in the case where there are multiple refrigeration components 3 and the refrigeration functions of the multiple refrigeration components 3 can be turned on or off independently, each refrigeration component 3 can still be configured to have multiple refrigeration partitions to achieve fine adjustment of the refrigeration intensity.

[0075] In a possible implementation, the fan 1 may include a driving member (not shown in the figure), which is connected to the refrigeration member 3 so as to drive the refrigeration member 3 to move. Therefore, the heat exchange position and heat exchange range between the refrigeration member 3 and the air can be changed by moving the refrigeration member 3, thereby adjusting the refrigeration intensity. This adjustment method also does not change the air volume, and this adjustment method has a high degree of freedom, and can seek fine adjustment of the refrigeration intensity.

[0076] The driving member may be any suitable driving mechanism, which may be transmission-connected with the refrigerating member 3 so as to drive the refrigerating member 3 to move. The specific transmission connection mode may be set by those skilled in the art according to the movement mode of the refrigerating member 3 to be achieved.

[0077] In a possible implementation, 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 inside of the storage element 4. In this case, the driving element 4 can be arranged to be able to synchronously drive the storage element 4 and the refrigeration element 3 to move, and the synchronous driving here means moving the two in a manner 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 the cooling medium in the storage element 4 to leak. Obviously, in this case, those skilled in the art can also choose to connect the extension portion and the storage element 4 in the form of dynamic sealing, so that the position of the refrigeration element 3 can be moved alone without worrying about the leakage of the cooling medium.

[0078] In a possible implementation, the driving member can change the ratio between the air flow in the through hole 31 and the air flow entering the housing 1 when driving the refrigeration member 3 to move. 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.

[0079] It can be understood that the air passing through the through hole 31 can have a relatively sufficient contact with the refrigeration component 3, so the degree of cooling will be higher than that of the air not passing through the through hole 31. When the ratio between the air flow in 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.

[0080] Furthermore, in the above embodiment, the ratio between the air flow in the through hole 31 and the air flow entering the housing 1 can be changed by translating or rotating the refrigeration element 3. Figure 2 Take the refrigeration element 3 with a middle plate structure as an example. Figure 2 In the position shown in the figure, 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 in the through hole 31 and the air flow 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 of the part of the through holes 31 will be reduced, thereby causing the ratio between the air flow in the through holes 31 and the air flow entering the shell 1 to change. Those skilled in the art can reasonably plan the path of the driving member when driving the refrigeration component 3 to move according to the specific spatial layout in the shell 1, the specific structural form of the refrigeration component 3, etc., which will not be repeated here.

[0081] 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.

[0082] 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 .

[0083] 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.

[0084] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
