Embodiment Construction

[0012] The summary of the invention has described the specific implementation manner of the present invention in detail, does not repeat here, need explain as follows: 1. see figure 1 , figure 2 , image 3 , Figure 4 , the present invention has upper and lower two rows of ventilation louvers, which are mutually rotated 90 degrees and arranged, and its supporting components are also arranged mutually rotated 90 degrees. 2. see Figure 5 , Figure 6 , since the lower hinge pins of the upper four-link (3) and the lower four-link (4) are fixed with the stop beam, the upper hinge pins of the upper four-link (3) and the lower four-link (4) are up and down The movement can drive the left and right hinge pins to move linearly inwardly or outwardly. 3. The present invention adopts the hydraulic device (1) to provide the power source for the up and down movement of the upper hinge pin of the four-bar linkage, mainly because the hydraulic device can directly provide up and down li...

Abstract

The invention discloses an automatic uniform heat-dissipation device for high-capacity lithium-ion power battery. The automatic uniform heat-dissipation device is mainly used for uniform heat-dissipation of a lithium-ion power battery and mainly comprises a hydraulic device (1), a piston rod (2), an upper four-bar linkage (3), a lower four-bar linkage (4), an upper support beam (5), upper louvers (6), a lower support beam (7), lower louvers (8), an upper stop beam (9), temperature sense probes (11), a hydraulic device fixing rod (13), upper connecting rods (14), lower connecting rods (17), a lower stop beam (18) and a rod (19), wherein the working principle of the device is that the piston rod (2) retracts to pull an upper hinge pin rod and the rod (19) on the four-bar linkage (3) to move upward; a left hinge pin rod and a right hinge pin rod of the four-bar linkage (3) move inward to drive the upper connecting rods (14) on the right and the left to move inward; a left row and a right row of upper louvers (6) rotate inward at an angle at the same time; cold air sent from a ventilation hood (10) is blown to a central region of a battery cabinet.

Description

technical field [0001] The invention is mainly used for uniform heat dissipation of large-capacity lithium-ion power batteries. Background technique [0002] I have applied for two invention patents: a large-capacity marine lithium-ion power battery cooling device and its application, application number 2016100467145; marine large-capacity cylindrical lithium-ion power battery cabinet, application number: 2016041200770090, both patents require A uniform heat dissipation device keeps the battery temperature difference between the battery center area and the surrounding area in the battery cabinet within the allowable range, otherwise it will affect the charging and discharging effect of the battery. Contents of the invention [0003] The present invention is exactly this kind of uniform heat dissipation device, which mainly consists of a hydraulic device (1), a piston rod (2), an upper four-link (3), a lower four-link (4), an upper support beam (5), an upper louver ( 6), l...
