SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a heat dissipation case for lithium cell.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model relates to a heat dissipation case for lithium cell, including box, baffle, battery cell and mainstream pipe, box inner wall equidistance fixedly connected with baffle, be provided with the mounting groove between the baffle, the inside fixedly connected with battery cell of mounting groove, the inside mainstream pipe that has all inlayed of box side, the inside shunt tubes that has inlayed of baffle.

Furthermore, the outer wall of the box body is symmetrically provided with water inlets, and one side of the outer wall of the box body, which is positioned at the water inlets, is symmetrically provided with water outlets.

Further, the water outlet is higher than the water inlet in level, and the water inlet and the water outlet are both communicated with the main flow pipe.

Further, the main flow pipe and the shunt pipe are communicated with each other.

Furthermore, the box body is made of an aluminum alloy material.

The utility model discloses the beneficial effect who reaches is: the utility model discloses compact structure, therefore, the clothes hanger is strong in practicability, separate each battery cell through the baffle, avoid the heat mutual conduction between the battery cell, avoid local overheated phenomenon, and use through the box cooperation that sets up at the inside sprue of box side and the inside shunt tubes cooperation aluminum alloy material of baffle, in giving the sprue and the inside coolant liquid of shunt tubes with the heat conduction that the battery gave out, effectually cool down the battery, safe in utilization has been ensured, and the delivery port setting on the box is in the top of water inlet, can ensure to fill up the sprue with the inside whole of sprue and sprue when adding the coolant liquid, can be abundant dispel the heat to the battery, improve the life of battery.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Examples

As shown in fig. 1-5, the utility model provides a heat dissipation case for lithium cell, including box 1, baffle 2, battery cell 6 and

mainstream pipe

7, 1 inner wall equidistance fixedly connected with baffle 2 of box is favorable to separating battery cell 6, avoids heat mutual conduction, is provided with mounting groove 3 between the baffle 2, the inside fixedly connected with battery cell 6 of

mounting groove

3, and 1 side of box is inside all to be inlayed and to have

mainstream pipe

7, and 2 inside inlays of baffle have shunt tubes 8.

Further, water inlet 4 has been seted up to 1 outer wall symmetry of box, conveniently pours into the coolant liquid into, and delivery port 5 has been seted up to 1 outer wall of box and the one side symmetry that is located water inlet 4, when needing to change the coolant liquid, conveniently discharges the inside coolant liquid of mainstream pipe 7 and shunt tubes 8.

Furthermore, the water outlet 5 is higher than the water inlet 4 in level, so that the main flow pipe 7 and the shunt pipe 8 are conveniently filled with the water, and the water inlet 4 and the water outlet 5 are communicated with the main flow pipe 7, so that the cooling liquid is convenient to enter and discharge.

Furthermore, main flow tube 7 and shunt tubes 8 communicate each other, make things convenient for the coolant liquid to circulate in main flow tube 7 and shunt tubes 8 inside, improve the result of use.
