In order to realize the above problem, the technical scheme of the utility model is that:

the utility model provides a through cooling liquid refrigerated cooling plate, includes first pressure manifold 19 and second pressure manifold 18, through a plurality of harmonica pipe intercommunications, its characterized in that between first pressure manifold 19 and the second pressure manifold 18: the first collecting pipe 19 is connected with a first guide pipe 14, one end of the first guide pipe 14 is connected to the first harmonica shaped tube 1, and the other end of the first guide pipe 14 is connected to the fourth harmonica shaped tube 2; the second collecting pipe 18 is connected with a second inverse flow pipe 15, one end of the second inverse flow pipe 15 is connected to the third harmonica pipe 5, and the other end of the second inverse flow pipe 15 is connected to the sixth harmonica pipe 4;

a fifth spacer 11, a sixth spacer 12, a first spacer 7 and a third spacer 9 are respectively arranged between the first harmonica tube 1 and the second harmonica tube 6 and between the third harmonica tube 5 and the fourth harmonica tube 2 on the first collecting pipe 19 and the second collecting pipe 18, and an inlet pipe 16 and an outlet pipe 17 are respectively arranged on the left side and the right side of the first spacer 7 of the second collecting pipe 18; the cooling medium flows in from the inlet pipe 16, and flows out from the outlet pipe 17;

a spacer seven 13 is arranged between the fourth harmonica tube 2 and the fifth harmonica tube 3 of the first collecting pipe 19;

a second spacer 8 is arranged between the second harmonica tube 6 and the third harmonica tube 5 of the second collecting pipe 18, and a fourth spacer 10 is arranged between the fifth harmonica tube 3 and the sixth harmonica tube 4.

The cooling medium is cooling liquid.

The utility model discloses an actively the effect does: the utility model discloses a cooling medium is the coolant liquid, through setting up the honeycomb duct on the pressure manifold, sets up the spacer in the manifold inside, through the combined action of honeycomb duct, spacer, pressure manifold, harmonica pipe for the coolant liquid forms fixed runner in the cooling plate, and the coolant liquid can not flow by mistake preface, and adjacent harmonica pipe that is through this design has formed high microthermal alternation, forms the cooling combination of a set of different temperatures through two harmonica pipes, cools off the battery, has improved cooling efficiency.

Detailed Description

The present invention will be further described with reference to the following specific embodiments. The number of the collecting main, harmonica tubes and the like in the illustrated embodiments does not limit the protection scope of the patent, and the number cannot be exhaustive due to limited space. All structures similar to this patent are within the scope of this patent.

Referring to fig. 1, a first flow guide pipe 14 is connected to the first collecting pipe 19, one end of the first flow guide pipe 14 is connected to the first harmonica shaped pipe 1, and the other end of the first flow guide pipe 14 is connected to the fourth harmonica shaped pipe 2; the second collecting pipe 18 is connected with a second inverse flow pipe 15, one end of the second inverse flow pipe 15 is connected to the third harmonica pipe 5, and the other end of the second inverse flow pipe 15 is connected to the sixth harmonica pipe 4; a fifth spacer 11, a sixth spacer 12, a first spacer 7 and a third spacer 9 are respectively arranged between the first harmonica tube 1 and the second harmonica tube 6 and between the third harmonica tube 5 and the fourth harmonica tube 2 on the first collecting pipe 19 and the second collecting pipe 18, and an inlet pipe 16 and an outlet pipe 17 are respectively arranged on the left side and the right side of the first spacer 7 of the second collecting pipe 18; the cooling medium flows in from the inlet pipe 16, and flows out from the outlet pipe 17; a spacer seven 13 is arranged between the fourth harmonica tube 2 and the fifth harmonica tube 3 of the first collecting pipe 19; a second spacer 8 is arranged between the second harmonica tube 6 and the third harmonica tube 5 of the second collecting pipe 18, and a fourth spacer 10 is arranged between the fifth harmonica tube 3 and the sixth harmonica tube 4.
