The embodiment of the application provides a refrigerating device, which can be a refrigerator for refrigerating and freezing food; or the air conditioner can also be used for refrigerating and cooling the interior of the building. For convenience of description and understanding of the technical solution of the present application, a refrigeration device is taken as an example of a refrigerator.

In this embodiment, the refrigerator includes a cabinet, an evaporator, and other cooling devices and accessories. The evaporator is arranged on the box body. The evaporator includes a heat exchange structure. As shown in fig. 1, a heat exchange structure shown in an embodiment of the present application is shown, where the heat exchange structure includes: an evaporation tube 10, a refrigeration liner 20 and heat conducting glue 30. The evaporator tube 10 is typically a round metal tube made of copper or aluminum. Aluminum or copper is selected as a material, so that the heat exchange efficiency of the evaporating pipe 10 is higher, and heat transfer and heat exchange can be better carried out. And a round pipe structure is selected, so that a larger surface area (namely a larger heat exchange area) can be obtained, and the heat exchange efficiency is favorably improved. Of course, in other embodiments, other materials capable of heat transfer and heat exchange can be used for the evaporation tube 10.

In addition, in order to further enhance the heat transfer efficiency of the evaporation tube 10, the evaporation tube 10 is formed in a winding type structure or a spiral disk structure. That is, the projection of the evaporation tube 10 on the surface of the refrigeration liner 20 is in a wave shape or an archimedes spiral shape. Thus, the evaporation tube 10 is designed and manufactured to be a circuitous structure or a spiral disc-shaped structure, so that the surface area of the evaporation tube can be greatly increased, the heat exchange operation area of the evaporation tube and the refrigeration liner 20 can be increased, and the effect of exchanging and transferring more heat in unit time is achieved. Of course, in other embodiments, the evaporating tubes 10 may also be formed in other structural shapes, and the number of the evaporating tubes may also be two or more, which may be selected according to actual needs.

The inner lumen of the evaporation tube 10 is formed as a flow channel, which can be used for flowing a heat exchange medium, such as but not limited to freon. When the evaporator works, the heat exchange medium flows through the circulation channel and exchanges heat with the outside through the pipe wall of the evaporation pipe 10, so that the refrigeration effect is achieved.

With reference to fig. 1, in some embodiments, the tube wall of the evaporation tube 10 is formed with a fitting portion 11; the refrigeration inner container 20 is arranged at one side of the evaporation tube 10 at intervals; the heat conducting glue 30 is disposed between the bonding portion 11 and the refrigeration liner 20 and connects and fixes the evaporation tube 10 and the refrigeration liner 20.

In addition to the above embodiments, preferably, the cross section of the evaporation tube 10 is D-shaped, and the bonding portion 11 is provided as a flat portion of the evaporation tube 10. The method for manufacturing the evaporating pipe 10 into the D shape comprises the following steps: the evaporating pipe winding device (namely, the device for winding the evaporating pipe 10 into a circuitous or spiral disc-shaped structure) is additionally provided with a flattening device, and the flattening device comprises a power part, a pressing part and a pressure-bearing part. The evaporating pipe 10 is placed on a pressure-bearing member, wherein the pressure-bearing member is formed with an arc-shaped concave surface matched with the shape of the circular evaporating pipe 10, so that the stable installation of the evaporating pipe 10 can be ensured. Then, the power member pushes the extrusion member to extrude the part of the evaporation tube 10 exposed out of the pressure-bearing member, and the extrusion working surface of the extrusion member is a plane, so that the exposed part of the evaporation tube 10 can be pressed into a plane part.

In addition, because the planar part is attached to the refrigeration liner 20, the connection area can be properly increased, the evaporation tube 10 can be firmly installed by virtue of the bonding force of the heat conducting glue 30 and is not easy to loosen, and meanwhile, the contact area with the refrigeration liner 20 is large, so that the heat transfer and heat exchange efficiency can be improved. The flat portion is disposed horizontally or approximately horizontally to the refrigeration liner 20. The approximately horizontal arrangement is considered to be a factor of processing error and assembly error, and the plane part and the refrigeration liner 20 can be considered to be horizontally attached to each other within an error allowable range even if a certain included angle or a certain distance exists between the plane part and the refrigeration liner 20; for example, when the gap between the planar portion and the cooling inner container 20 is 0.01mm to 0.03mm or the angle between the planar portion and the cooling inner container 20 is 0 ° to 3 °, it can be considered that the planar portion and the cooling inner container 20 are horizontally attached to each other.

It should be noted that, of course, the formation of the evaporation tube 10 with a D-shaped cross section is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application. In other embodiments, the cross-section of the evaporating tube 10 can be made into other shapes, such as C-shape, L-shape, etc.

It should be noted that, when the evaporation tube 10 is D-shaped, only a part of the outer tube wall may be machined to form a combined structure of a plane and an arc surface, and the flow channel is still circular, that is, the cross-sectional shape of the outer tube wall of the evaporation tube 10 is different from the cross-sectional shape of the flow channel inside; or, the outer tube wall may be partially machined to have a combined structure of a plane and an arc surface, and the inner wall of the flow channel also includes a plane and an arc surface, that is, the cross-sectional shape of the outer tube wall of the evaporation tube 10 is the same as the cross-sectional shape of the inner flow channel.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the heat exchange structure in the above scheme is applied to an evaporator of a refrigeration device, so as to improve the working performance of the refrigeration device by improving the installation mode of the evaporation tube 10. Specifically, during installation, the adhering portion 11 is first formed on the evaporation tube 10, and then the adhering portion 11 is directly adhered and fixed to the refrigeration liner 20 by the heat conductive adhesive 30, so that the evaporation tube 10 and the refrigeration liner 20 are integrally connected by the heat conductive adhesive 30. Compare in the tradition mounting means that adopts the aluminium foil to paste, evaporating pipe 10 in this scheme is because adopt heat conduction glue 30 directly to assemble fixedly with refrigeration inner bag 20, so can not have aluminium foil damage or manual error to paste partially and cause evaporating pipe 10 to install insecurely, cause the foaming material to get into between evaporating pipe 10 and the refrigeration inner bag 20, influence the problem that evaporating pipe 10 heat transfer efficiency became invalid even, also can not have the air expend with heat and contract with cold simultaneously and lead to the blister inner bag to produce the swell and influence the high temperature resistance ability of refrigerator, and because heat conduction glue 30 itself possesses good heat conductivility, thereby help the heat to carry out high-efficient conduction to evaporating pipe 10 by refrigeration inner bag 20, promote refrigerating plant's refrigerating capacity.

With reference to fig. 2, in addition to any of the above embodiments, the attaching portion 11 is a first concave arc surface 12 formed by recessing the outer wall of the evaporation tube 10, and one side of the heat-conducting glue 30 facing the evaporation tube 10 is filled in the first concave arc surface 12. The laminating portion 11 is designed and manufactured into the first concave cambered surface 12, and compared with the traditional convex cambered surface of a round pipe and a plane in a shape like a Chinese character 'D', the surface area is larger, so that the bonding area of the laminating portion and the heat-conducting glue 30 is larger, the bonding force of the heat-conducting glue 30 and the evaporating pipe 10 is larger, the connecting strength of the evaporating pipe 10 and the refrigeration liner 20 can be further improved, and the evaporating pipe 10 is effectively prevented from falling off.

Further, on the basis of the above embodiment, a second concave arc surface may be concavely formed on the surface of the refrigeration liner 20, and one side of the heat-conducting glue 30 facing the refrigeration liner is filled in the second concave arc surface. The surface design of refrigeration inner bag 20 is made into the second indent cambered surface, compares in traditional planar structure, and its surface area is bigger, therefore bigger with the combined area who glues 30, and the adhesive force of heat conduction glue 30 and refrigeration inner bag 20 is just bigger, so alright further improve the joint strength who glues 30 and refrigeration inner bag 20 with the heat conduction, effectively prevent that evaporating pipe 10 and heat conduction glue 30 wholly from taking place to drop.

It should be noted that the first concave arc surface 12 and the second concave arc surface are arranged without affecting the inherent working performance of the evaporating tube 10 and the refrigerating liner 20. And the first concave cambered surface 12 and the second concave cambered surface can be selected alternatively or simultaneously, and can be specifically selected according to actual needs.

With reference to fig. 4, in still other embodiments, an anti-glue-overflow groove 21 is formed in the surface of the refrigeration liner 20, and the heat conducting glue 30 is filled in the anti-glue-overflow groove 21. Through the glue overflow prevention groove 21 designed and manufactured on the surface of the refrigeration inner container 20, the phenomenon that the heat-conducting glue 30 overflows to the two sides of the bonding part when gluing and bonding the evaporation tube 10 to generate pressure can be avoided, less heat-conducting glue 30 participates in connection to influence the connection quality, and meanwhile, the phenomenon that the overflow heat-conducting glue 30 generates pollution is prevented. Alternatively, the cross section of the glue overflow preventing groove 21 may be arc, rectangular, trapezoidal, etc., and may be specifically selected according to actual needs.

With reference to fig. 3, in addition to any of the above embodiments, the inner wall of the evaporation tube 10 is formed with a spiral groove structure 13. The spiral groove structure 13 is designed and manufactured on the inner wall of the evaporation tube 10, so that the laminar flow state of the heat exchange medium can be destroyed, and particularly the laminar flow state of the heat exchange medium close to the side of the refrigeration liner 20 is obviously changed, thereby increasing the heat conductivity coefficient between the heat exchange medium and the evaporation tube 10 and improving the refrigeration speed. Further, the spiral groove structure 13 may be a double spiral or multi-spiral groove structure 13, so that the laminar flow state of the heat exchange medium can be better destroyed, and the heat conductivity coefficient between the heat exchange medium and the evaporator is further enhanced.

Further, each of the spiral grooves may be continuous or may be a discontinuous structure.

Further, the values of the groove width, the groove depth, the helix angle, and the like of the spiral groove are not particularly limited herein, and may be specifically selected according to actual needs.

In still other embodiments, the attaching portion 11 is a plane formed by pressing with a flattening device, the plane is concavely provided with at least two strip-shaped grooves arranged side by side at intervals, and the length extension directions of the strip-shaped grooves are parallel to or perpendicular to or at an included angle with the axis of the evaporation tube 10. So, through making two at least bar grooves, can further increase evaporating pipe 10 and heat-conducting glue 30's area of contact, reinforcing adhesion guarantees that the evaporating pipe 10 installation is firm. The arrangement shape of the strip-shaped grooves can be parallel to, perpendicular to or form an included angle with the axis of the evaporation tube 10, and the product structure can be enriched.

Alternatively, as an alternative to the above embodiment, the attaching portion 11 is still a plane formed by pressing through a flattening device, but at least two strip-shaped protrusions are protruded from the plane and arranged side by side at intervals, and the length extension direction of the strip-shaped protrusions is parallel to, or perpendicular to, or at an angle with the axis of the evaporation tube 10. So, protruding through two at least bar productions, can further increase evaporating pipe 10 and the area of contact of heat-conducting glue 30, reinforcing adhesion guarantees that evaporating pipe 10 installs firmly. The arrangement shape of the strip-shaped bulges can be parallel to, vertical to or form an included angle with the axis of the evaporation tube 10, so that the product structure can be enriched.

Alternatively, as an alternative to the two embodiments, the attaching portion 11 is still a plane formed by pressing through a flattening device, but the plane is concave and is provided with a strip-shaped groove and a strip-shaped protrusion, and the number of the strip-shaped groove and the strip-shaped protrusion may be the same or different, and may be one, two or more. The bar groove with the protruding interval of bar is arranged side by side or mutually perpendicular arranges or is the contained angle setting, the bar groove with the protruding length extending direction of bar all with the axis of evaporating pipe 10 is parallel or mutually perpendicular or is the contained angle and arranges. So, protruding and the bar groove of design preparation bar simultaneously, can further increase evaporating pipe 10 and the area of contact of heat-conducting glue 30, reinforcing adhesion guarantees that the evaporating pipe 10 installation is firm. And the shape of arranging of bar arch and bar groove can be parallel with the axis of evaporating pipe 10, perpendicular or be the contained angle, can richen product structure and variety, reduces the manufacturing degree of difficulty.

In addition, on the basis of any one of the above embodiments, the heat exchange structure further includes a suction cup body, the suction cup body is disposed on the refrigeration liner 20, and the suction cup body and the evaporation tube 10 are fixed in a vacuum adsorption manner. Specifically, the suction cup body is a vacuum suction cup, when the evaporation tube 10 is pressed and bonded on the heat conducting glue 30, the evaporation tube 10 is in contact with the suction cup body for extrusion, the suction cup body generates vacuum suction force to adsorb the evaporation tube 10, and therefore the installation firmness of the evaporation tube 10 can be further improved under the constraint of the composite force of bonding force and the vacuum suction force.

In addition, it should be noted that, compare and install on the evaporating plate in traditional evaporating pipe, the heat transfer structure difference that the evaporating plate was installed on the refrigeration inner bag again is because the evaporating pipe is direct mount on the refrigeration inner bag in this scheme, therefore can save this way middle thermal resistance barrier of evaporating plate, makes heat transfer transmission more smooth and easy, and cold volume transmission loss reduces.
