Detailed Description

The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.

Please refer to fig. 1 and fig. 2, which are a schematic perspective view and a schematic cross-sectional view of a uniform temperature heat dissipation structure according to the present invention. The invention provides a temperature-equalizing heat-dissipating container structure of a lithium battery and a combined module thereof, wherein the temperature-equalizing heat-dissipating container structure 1 can be made of materials with good heat conductivity, such as aluminum and the like, and comprises a base 10 and an accommodating surrounding frame 11 vertically arranged on the base 10; wherein:

the receiving enclosure 11 includes a pair of first heat conducting walls 110 spaced apart from each other, and another pair of second heat conducting walls 111 spaced apart from each other, and the base 10, and the first heat conducting walls 110 and the second heat conducting walls 111 enclose a hollow receiving area 12. As shown in fig. 2, the base 10 has a bottom surface 100 corresponding to an inner wall surface of the accommodating area 12, the first heat conducting wall 110 has a limiting surface 110a corresponding to the inner wall surface of the accommodating area 12, and the accommodating area 12 forms an inlet 120 above the accommodating enclosure 11. In addition, the outer edge of the base 10 may further protrude outward to form a lower flange 101, and the receiving frame 11 may further protrude outward to form an upper flange 112, and a plurality of heat dissipation portions 110b, 111a are disposed on the outer wall surfaces of the first heat conduction wall 110 and the second heat conduction wall 111, and the heat dissipation portions 110b, 111a may be vertical ribs arranged at intervals and are respectively connected between the upper flange 112 and the lower flange 101.

As shown in fig. 2, the second heat conducting walls 111 may be vertically arranged in parallel with each other; the pair of first heat transfer walls 110 are vertically arranged at intervals gradually increasing from bottom to top. In detail, the limiting surface 110a of each first heat conducting wall 110 is inclined outward by an angle θ, so that the width W1 of the receiving area 12 on the bottom surface 100 is greater than the width W2 of the inlet 120 above the receiving area.

Referring to fig. 3 and 4, the temperature-equalizing heat-dissipating container structure 1 is used to load at least one lithium battery 2 to form a temperature-equalizing heat-dissipating combined module of the lithium battery. The lithium battery 2 may include a battery cell 20 and a heat transfer casing 21 sandwiched outside two sides of the battery cell 20, wherein the battery cell 20 may be an aluminum foil package, and the heat transfer casing 21 may also be made of a material with good heat conductivity, such as aluminum, so as to be vertically disposed in the accommodating area 12 through the disposing opening 120 of the uniform temperature heat dissipation container structure 1, and to contact the bottom surface 100 and the limiting surface 110a through the heat transfer casing 21, as shown in fig. 5, thereby providing a uniform temperature heat dissipation effect for the battery cell 20 in the lithium battery 2. Furthermore, the heat conductive casing 21 of each lithium battery 2 may have a thicker heat conductive frame portion 210 outside, the heat conductive frame portion 210 has a front surface 210a and a lateral surface 210b, and the lateral surface 210b is used for contacting with and opposing the limiting surface 110a of the first heat conductive wall 110; the front surface 210a may be configured to allow the front surfaces 210a of the lithium batteries 2 to contact each other when the lithium batteries 2 are arranged in the uniform-temperature heat dissipation container structure 1.

As shown in fig. 5, the first heat conducting walls 110 are vertically arranged at intervals gradually increasing from bottom to top, so that the lithium battery 2 is tightly pressed between the first heat conducting walls 110. Thus, the lithium batteries 2 arranged in the uniform-temperature heat dissipation container structure 1 can obtain a reliable positioning effect, so as to prevent the single lithium batteries 2 from shaking, ensure that each lithium battery 2 is in reliable contact with the uniform-temperature heat dissipation container structure 1, and uniformly dissipate heat generated by the battery core 20 in use and conduct the heat to the outside of the uniform-temperature heat dissipation container structure 1; meanwhile, the lithium batteries 2 can also contact with each other through the front surfaces 210a thereof, so that heat is not accumulated in the lithium batteries 2 sandwiched therebetween, and the heat conduction effects of uniform temperature and heat dissipation can be achieved through the contact of the front surfaces 210a and the contact of the respective lateral surfaces 210b with the first heat conduction wall 110.

Therefore, the temperature-equalizing heat-radiating container structure of the lithium battery and the combined module thereof can be obtained through the structural composition.
