Description

A temperature-controlled self-protection heat transfer structure and heat-insulating container Technical Field

[0001] The present invention relates to the field of temperature control and heat preservation, and in particular to a temperature control self-protection heat transfer structure and a heat preservation container. Background Art

[0002] Insulated containers are primarily used to maintain a constant temperature. Therefore, they are typically used to hold hot or ice water. However, in practice, these containers often contain hot water that cannot be drunk directly. Instead, the hot water must be poured out to dissipate the heat and cool down the container.

[0003] To address this issue, existing technologies employ bimetallic strips to achieve both cooling and heat preservation. Specifically, a heat transfer structure is placed between the outer bottle and the inner liner. This structure deforms the bimetallic strip, connecting the heat conducting plate to the outer and inner liner bodies, thereby achieving a heat dissipation effect. Furthermore, once the temperature inside the bottle drops to a certain level, the bimetallic strip recovers, disconnecting the heat conduction path between the inner and outer liner bodies, maintaining a constant temperature within the inner liner.

[0004] Then during actual use, when the temperature is too high, the bimetallic strip will continue to press on the thermal conductive sheet, causing the thermal conductive sheet to deform, thereby causing the thermal conductive sheet to fail when connecting or disconnecting the heat conduction channel between the inner bottle body and the outer bottle body. Summary of the Invention

[0005] The first purpose of the present invention is to provide a temperature-controlled self-protection heat transfer structure, which can automatically disconnect the heat transfer channel by the elastic heat conductive sheet when the temperature reaches the set upper limit, thereby avoiding the problem of deformation of the elastic heat conductive sheet due to continuous compression under high temperature conditions.

[0007] Constrained but not restricted in deformation means that the first bimetallic strip and the second bimetallic strip can be deformed in the constrained cavity but cannot escape from the constrained cavity, thereby ensuring stable operation of the sudden jump temperature control component.

[0008] Furthermore, the above-mentioned first bimetallic strip and the second bimetallic strip both include a central body and edge portions distributed around the circumference of the central body; when the first bimetallic strip and the second bimetallic strip are not deformed, they both bend toward the heat-generating object, and the edge portion of the first bimetallic strip cooperates with the edge portion of the second bimetallic strip to form a stacked state; the central body of the second bimetallic strip when it is not deformed by heat supports the central body of the first bimetallic strip after it is deformed by heat, and the edge portion of the first bimetallic strip after it is deformed by heat deforms toward the heat-dissipating object and pushes the elastic thermal conductive sheet; when the first bimetallic strip and the second bimetallic strip are both deformed by heat, they both bend toward the heat-dissipating object, and the edge portion of the first bimetallic strip cooperates with the edge portion of the second bimetallic strip to form a reverse stacked state.

[0009] As a modified design, the first bimetallic strip and the second bimetallic strip may be designed to be in the shape of a spherical arc with a certain thickness.

[0010] Furthermore, the mounting base includes a base and a fixing strip; the edge of the base is provided with a plurality of limiting portions for limiting the translation of the first bimetallic strip and the second bimetallic strip along the bottom surface of the base; the fixing strip is fixedly mounted above the base; the base, the limiting portions, and the fixing strip form a constrained mounting cavity for constraining the first bimetallic strip and the second bimetallic strip within but not restricting their deformation;

[0013] When the first bimetallic strip is deformed by heat and the second bimetallic strip is not deformed by heat, the edge of the first bimetallic strip, supported by the second bimetallic strip, pushes the free end of the elastic heat conductive strip from the opening of the corresponding constraint mounting cavity to contact the heat dissipation object to form heat conduction.

[0039] Constrained but not restricted in deformation means that the first bimetallic strip 12 and the second bimetallic strip 13 can be deformed in the constrained cavity but cannot escape from the constrained cavity, thereby ensuring stable operation of the sudden jump temperature control component 1.

[0040] The first bimetallic strip 12 and the second bimetallic strip 13 both include a central body and edge portions distributed around the circumference of the central body; when the first bimetallic strip 12 and the second bimetallic strip 13 are not deformed, they both bend toward the heating object 3, and the edge portions of the first bimetallic strip 12 cooperate with the edge portions of the second bimetallic strip 13 to form a stacked state; the central body of the second bimetallic strip 13 when not deformed by heat supports the central body of the first bimetallic strip 12 after it is deformed by heat, and the edge portion of the first bimetallic strip 12 after it is deformed by heat deforms toward the heat dissipation object 4 and pushes the elastic thermal conductive sheet 21; when the first bimetallic strip 12 and the second bimetallic strip 13 are both deformed by heat, they both bend toward the heat dissipation object 4, and the edge portions of the first bimetallic strip 12 cooperate with the edge portions of the second bimetallic strip 13 to form a reverse stacked state.

[0041] Of course, the first bimetallic strip 12 and the second bimetallic strip 13 can also be designed to be in the shape of a spherical arc with a certain thickness.

[0042] The mounting base 11 includes a base 111 and a fixing bar 112. The edge of the base 111 is provided with a plurality of limiting portions 113 for limiting the translation of the first bimetallic strip 12 and the second bimetallic strip 13 along the bottom surface of the base. The fixing bar 112 is fixedly mounted above the base 111. The base 111, the limiting portions 113, and the fixing bar 112 form a constrained mounting cavity for constraining the first and second bimetallic strips 12 and 13 within the cavity without restricting their deformation.

[0043] The constrained installation cavity is located at the portion where the fixing strip 112 does not cover the base 111, forming an opening of the constrained installation cavity; the fixing strip 112 is located at the center of the base 111, and the two sides of the constrained installation cavity are symmetrically formed with openings;

[0044] The heat conducting components 2 are symmetrically provided on both sides of the mounting base 11; the heat conducting components 2 also include a fixing base 22; one end of the elastic heat conducting sheet 21 is fixedly mounted on the heat generating object 3 via the fixing base 22; the other end of the elastic heat conducting sheet 21 is a free end; the free end of the elastic heat conducting sheet 21 is located at the opening of the constraint mounting cavity on the corresponding side;

[0045] When the first bimetallic strip 12 is deformed by heat and the second bimetallic strip 13 is not deformed by heat, the first bimetallic strip 12 is supported by the second bimetallic strip 13, and the edge of the first bimetallic strip 12 pushes the free end of the elastic heat conductive plate 21 from the opening of the corresponding constraint installation cavity to contact the heat dissipation object 4 to form heat conduction.

[0046] In this embodiment, two limiting portions 113 are provided on the base 111 at both ends of the fixing bar 112; the two limiting portions 113 on the base 111 at one end where the fixing bar 112 is fixed are symmetrically arranged about the center line of the fixing bar 1113, and the two limiting portions 113 on the base 111 at the other end where the fixing bar 112 is fixed are also symmetrically arranged about the center line of the fixing bar 1113, as shown in Figures 6 and 7.

[0047] A protrusion 112 - 1 is provided on the end surface of the fixing strip 112 facing the base 111 ; the protrusion 112 - 1 acts on the first bimetallic strip 12 ; under the action of the protrusion 112 - 1 , the first bimetallic strip 12 forms a distance from the fixing strip 112 , thereby ensuring that there is plenty of space for the first bimetallic strip 12 to deform, thereby better pushing the elastic thermal conductive sheet 21 .

[0048] The end surface of the elastic heat conductive sheet 21 facing the edge of the first bimetallic strip 12 is provided with a protrusion 211 extending into the constraint installation cavity; the protrusion 211 cooperates with the edge of the first bimetallic strip 12 to push the free end of the elastic heat conductive sheet 21.

[0049] The protrusions 211 are formed by stamping the elastic heat conductive sheet 21 .

[0050] One end of the elastic heat conductive sheet 21 is fixedly pressed onto the heat generating object 3 via a fixing seat 22 and is in contact with and attached to the heat generating object 3 .

[0051] See Figure 9. The heat-insulating container in the present invention includes an outer bottle body 5 and an inner bottle body 6; the outer bottle body 5 is mounted on the outside of the inner bottle body 6; the inner bottle body 6 is fixedly connected to the outer bottle body 5; the outer bottle body 5 is a heat dissipation object 4; the inner bottle body 6 is a heat-generating object 3; the outer wall of the inner bottle body 6 is provided with a temperature-controlling self-protection heat transfer structure as described above.

[0052] The outer wall of the inner bottle body 6 is provided with a plurality of temperature-controlling self-protection heat transfer structures.

[0053] As an optimized design, the outer wall of the inner liner 6 is provided with a layer of temperature-controlling, self-protecting, heat-transferring structures, distributed along its axis. Furthermore, the outer wall of the inner liner 6 is provided with one or more layers of temperature-controlling, self-protecting, heat-transferring structures, arranged along its axis. This arrangement can be designed based on thermal conductivity requirements.

[0054] The outer surface of the outer bottle body 6 is coated with color-changing ink that changes color when heated.

[0055] The various states when the present invention is used are described as follows:

[0056] The initial state, as shown in FIG3 , is generally an unused state or the temperature inside the inner bottle body 6 has not yet reached the deformation temperature of the first bimetallic strip 12. At this time, the edges of the first bimetallic strip 12 and the second bimetallic strip 13 are bent toward the inner bottle body 6. Since the first bimetallic strip 12 and the second bimetallic strip 13 are bent in the same direction, the first bimetallic strip 12 and the second bimetallic strip 13 are stacked, and the stack height is not high enough for the first bimetallic strip 12 to push the elastic thermal conductive sheet 21.

[0057] The heat conduction state, as shown in Figure 4, generally occurs when the temperature of the inner bottle body 6 reaches or exceeds the deformation temperature of the first bimetallic strip 12, but does not reach the deformation temperature of the second bimetallic strip 13. At this point, the edge of the first bimetallic strip 12 bends toward the outer bottle body 5, while the edge of the second bimetallic strip 13 bends toward the inner bottle body 6. At this point, supported by the second bimetallic strip 13, the edge of the first bimetallic strip 12 acts on the corresponding elastic thermally conductive sheet 21 through the opening of the constrained mounting cavity, thereby pushing the elastic thermally conductive sheet 21 into contact with the outer bottle body 5, forming a heat conduction channel.

[0058] The self-protection state, as shown in Figure 5, is generally when the temperature of the inner bottle body 6 reaches or exceeds the deformation temperature of the second bimetallic strip 12; if this temperature is maintained for a long time, the elastic thermal conductive sheet 21 is at risk of deformation. Therefore, the edge of the second bimetallic strip 12 also bends toward the outer bottle body 5, causing the first bimetallic strip 12 and the second bimetallic strip 13 to bend in the same direction again, but this time the bending is in the same direction toward the outer bottle body 5. Due to the bending of the second bimetallic strip 13, the first bimetallic strip 12 and the second bimetallic strip 13 form a reverse stacking state, and the stacking height is not enough for the first bimetallic strip 12 to push the elastic thermal conductive sheet 21. As a result, the heat conduction channel is disconnected, completing the self-protection.

[0059] Based on the above state, it can be seen that if the temperature inside the inner bottle body 6 drops below the deformation temperature of the second bimetallic strip 12, the second bimetallic strip 12 will restore its initial shape, so that the temperature-controlled self-protection heat transfer structure returns to the heat conduction state and continues to cool down.

[0060] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
