Description

TECHNICAL FIELD

[0001] The utility model belongs to new energy battery technical field especially relates to a new energy battery heat abstractor. BACKGROUND

[0002] Three kinds of new energy batteries: one is NCM ternary lithium battery (representing the production manufacturer "Ningde times"), another is NCA ternary lithium battery (representing the production manufacturer "Suzuki"), the last kind is iron lithium phosphate battery (representing the production manufacturer "BYD"), and it includes zinc series batteries such as zinc-manganese battery, zinc-silver battery etc. according to the positive and negative electrode materials used in the battery, nickel series batteries such as cadmium-nickel battery, hydrogen-nickel battery etc., lead series batteries such as lead-acid battery, lithium ion battery, lithium-manganese battery, manganese dioxide series batteries such as zinc-manganese battery, alkaline-manganese battery etc., air (oxygen) series batteries such as zinc-air battery etc.

[0003] The existing new energy television heat abstractor is roughly divided into air cooling and liquid cooling scheme, and the air cooling scheme is not ideal when facing the battery with large heat generation, and the liquid cooling scheme is mostly through the S-shaped heat dissipation pipe to simultaneously dissipate heat for multiple batteries in array, since the batteries are arranged in array, the heat dissipation pipe can dissipate heat for the two side surfaces of the battery, but the other two side surfaces are difficult to dissipate heat, and the side surfaces of adjacent batteries heat up quickly without the influence of the heat dissipation pipe, which affects the service life and stability of the battery. One of the existing solutions is to add a heat conduction block between the two side surfaces of the battery, and the heat conduction block transmits the heat of the side surface of the battery to the heat dissipation pipe, but since the array density of the battery is high and the gap is small, the contact area of the heat conduction block and the heat dissipation pipe is small, and the heat dissipation effect is not good. The second solution is to lay a relatively complex heat dissipation pipe, and the heat dissipation pipe is branched to achieve simultaneous heat dissipation for the four side surfaces of the battery, and the heat dissipation effect is good, but the cost is high, and the thin branch flow channel is troublesome in subsequent maintenance.

[0004] Therefore, the new energy battery heat abstractor is proposed to solve the above problems. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Referring to Figures 1-3 A new energy battery cooling device, comprising a battery box 1, a plurality of battery bodies 2 are arranged in the battery box 1, S-shaped cooling pipes 3 are arranged between adjacent rows of battery bodies 2, and the side surfaces of the cooling pipes 3 are attached to the battery bodies 2; gaps 4 are arranged between adjacent columns of battery bodies 2; and a cooling assembly 5 is arranged on one side of the battery box 1 and matched with the cooling pipes 3. The cooling assembly 5 is a prior art, comprising a water pump, a water tank and cooling liquid. Since the cooling assembly 5 is relatively common in the field of heat dissipation, no further description is given here.

[0023] Referring to Figures 4-5 A plurality of first grooves 6 matched with the gaps 4 are formed in the bottom surface of the battery box 1; a fixed plate 7 is fixedly arranged on the upper portion of the battery box 1, and the bottom surface of the fixed plate 7 is attached to the top surface of the battery body 2; and the top surface of the battery body 2 is higher than the top end of the cooling pipe 3.

[0024] The new energy battery cooling device, when in use, the cooling assembly 5 is turned on to make the cooling liquid circulate in the cooling pipes 3, and the cooling liquid thus cools the two side surfaces of the battery body 2. Air enters the gaps 4 between adjacent batteries from the first grooves 6 in the bottom of the battery box 1 to assist in air cooling and heat dissipation of the other two side surfaces of the battery body 2, and is then discharged from the gap between the cooling pipe 3 and the fixed plate 7.

[0025] It should be noted that since the cooling pipe 3 is S-shaped, the three side surfaces of the battery body 2 at one end are attached to the cooling pipe 3, and the two side surfaces of the battery body 2 at the other end are attached to the cooling pipe 3. At this time, heat spreading blocks 15 attached to the battery body 2 are fixedly arranged on both sides of the bending portion of the cooling pipe 3, so that water cooling heat dissipation can be realized for the three side surfaces of the battery body 2 at all end portions, which is better than the effect of auxiliary air cooling heat dissipation, and at the same time, the problem of air duct disorder caused by auxiliary air cooling heat dissipation when dissipating heat for the battery body 2 at the edge is avoided.

[0026] A metal cap 8 protruding from the top surface of the battery body 2 is arranged; a plurality of through holes 9 for the metal cap 8 to pass through are formed in the fixed plate 7, and the top end of the metal cap 8 is higher than the top surface of the fixed plate 7. The metal cap 8 is a prior art, which is convenient for external electrical connection. The fixed plate 7 can provide limiting for the battery body 2 and improve the stability of the battery fixation.

[0027] In order to further improve the stability and safety of the battery fixation, the through hole 9 is fixedly connected with a protection ring 10, the side surface of the protection ring 10 is attached to the metal cap 8, the bottom surface of the protection ring 10 is attached to the top surface of the battery body 2, and the protection ring 10 can be made of insulating rubber material.

[0028] A plurality of limiting blocks 11 for cooperating with the battery body 2 are fixedly connected to the top of the first groove 6. The limiting blocks 11 can provide lower fixation for the battery, thereby improving the stability of the battery.

[0029] In order to guide and facilitate the air exhaust, a plurality of second grooves 12 are formed in the top surface of the fixed plate 7, and the second grooves 12 are located between the adjacent rows of the battery body 2.

[0030] A ventilation hole 13 is formed in the top surface of the battery box 1, and a fan 14 for blowing air outward is fixedly installed at the ventilation hole 13. The fan 14 cooperates with the ventilation hole 13 to accelerate the air circulation of the battery box 1, thereby improving the auxiliary air cooling effect.

[0031] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
