The first pulsating heat pipe assembly and the heat collector (1) are vacuumized in advance, and are processed into a closed vacuum loop with the inside of the vacuum loop being a vacuum structure, and then a heat transfer working medium is filled; when the liquid is filled, a state that the vapor column and the liquid column are alternately formed in the pipe is caused under the action of capillary force and friction force resistance of the pipe wall, when the vapor column and the liquid column pass through the evaporation section, heat is absorbed, when the vapor column passes through the condensation section, the heat is released, the vapor column contracts, due to the fact that temperature difference exists between the evaporation section and the condensation section, vapor bubbles expand when being heated in the evaporation section and contract when being cooled in the condensation section, pressure difference is formed at the cold end and the hot end, working medium is caused to flow in a reciprocating mode in the pipe, external mechanical work or electric work is not consumed, self oscillation is achieved under the heat drive, and meanwhile heat dissipation is achieved;
The upper surface of the shell is provided with a heat collector (1), and the heat collector (1) is laid on the upper surface of the shell along the horizontal direction;
the battery pack comprises a plurality of single batteries (2), wherein each single battery (2) is vertically arranged in the shell, the single batteries (2) are mutually arranged in parallel, and the shell comprises an upper cover (3) and a lower cover (4) matched with the upper cover (3);
The upper cover (3) is provided with a plurality of upper positioning holes arranged along the height direction of the upper cover, the lower cover (4) is provided with a plurality of lower positioning holes arranged along the height direction of the lower cover, the number of the upper positioning holes and the number of the lower positioning holes are the same as that of the single batteries (2), the upper positioning holes and the lower positioning holes are coaxially arranged one by one to form a positioning hole body capable of accommodating the single batteries (2), and one single battery (2) is arranged in any positioning hole body;
Each row of first pulsating heat pipe assemblies comprises a plurality of U-shaped inner peripheral pulsating heat pipes (5) and a U-shaped outer peripheral pulsating heat pipe (6) which surrounds the outside of all U-shaped inner peripheral pulsating heat pipes (5);
The heat collector (1) is specifically a second pulsating heat pipe component;
the second pulsating heat pipe assembly is specifically a plurality of linear pulsating heat pipes (7) which are arranged in parallel, and the linear pulsating heat pipes (7) are respectively communicated with the U-shaped inner peripheral pulsating heat pipes (5) in a one-to-one correspondence manner;
the cross section of the first pulsating heat pipe assembly and the second pulsating heat pipe assembly is elliptical, circular or square;
The first pulsating heat pipe assembly and the second pulsating heat pipe assembly are both composed of a heat conduction silica gel body.
