[0002] At present, the heat dissipation of automobile lithium batteries usually adopts other heat dissipation methods such as air cooling, and the heat dissipation effect is poor. If it is cooled by water cooling, a new water cooling device needs to be designed to dissipate heat. For heat dissipation, the cooling plate is the first choice for heat dissipation. However, the current structure of the cooling plate is only to open a cavity in the cooling plate for cooling water to flow through. One side of the cavity is connected to the water inlet pipe, and the other side is connected to the water outlet pipe, thereby forming a cooling plate. The temperature difference between the two ends is large, and the water flow passes through the cavity quickly, so the heat dissipation effect is poor

Embodiment Construction
[0010] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0011] Such as figure 1 As shown, a grid of a lithium battery cooling plate includes six grooved tubes 1 arranged in parallel, one end of the six grooved tubes 1 is connected through a connecting tube 2, and the other ends of the two grooved tubes 1 in the middle are connected to each other. The water end 3, the other end of the four grooved pipes 1 on the outside is the water outlet 4, the height of the water tank in each of the grooved pipes 1 is 1 / 2 of the width of the water tank, and the thickness of the grooved pipe 1 is 1 / 2 of the width of the water tank. One-twelfth, a number of baffles 5 are staggered on both sides of the water tank, and the baffle...

The invention discloses a grating for a lithium battery cooling plate. The grating comprises six fluted tubes arranged in parallel, wherein one ends of the six fluted tubes are communicated by virtue of connecting tubes; the other ends of two middle fluted tubes are water inlet ends; the other ends of the rest four fluted tubes on the outer side are water outlet ends; the water tank height in each fluted tube is 1 / 2 of the water tank height; the thickness of each fluted tube is 1 / 12 of the water tank width; multiple baffles are respectively arranged on two sides in the water tank in a staggered mode; the baffles and the fluted tubes are arranged in an inclined mode; the angle between each baffle and each fluted tube is 60 degrees; and the width of each baffle is 2 / 3 of the width of the water tank. The baffles are arranged on two sides of the water tank, so that water can flow in the water tank in an S shape, the heat dissipation time is increased, and the heat dissipation effect is improved.
