Problems solved by technology
Due to its huge size, it will generate a lot of heat when charging and discharging, and the closed compartment makes it unable to dissipate heat in a timely and effective manner.
The accumulation of heat will greatly affect the performance of the battery pack, shorten the life and create a fire hazard
[0003] At present, there is no design specifically for the heat dissipation of power battery packs for locomotives, and it is imminent to solve this problem

Embodiment Construction
[0026] figure 1 It is the appearance front view of the present invention, figure 2 Its internal schematic diagram. The present invention includes a box body, several ventilators 4 , air inlet louvers 2 , and air outlet louvers 1 , and each ventilator 4 is provided with a corresponding exhaust duct 8 .
[0027] The box body includes side walls, a top cover, and an installation chassis. The power battery pack is divided into several different boxes 6, and the boxes 6 are arranged in several rows along the length direction of the power battery compartment ( figure 1 Shown in two columns), each column has several rows, and the boxes 6 do not touch each other. Sub-ventilation passages are formed between adjacent boxes 6 in the same row and between boxes 6 in each row, and each sub-ventilation passage forms an integral ventilation passage. The upper position in the middle of the two rows of boxes 6 is the air duct (such as image 3 shown). Preferably, in order to achieve bette...

The invention provides a locomotive power battery pack heat radiation system. The system comprises a carriage containing several power battery packs, several ventilators, an air inlet shutter, several exhausting ducts corresponding to the ventilators, an air outlet shutter and a drainage pipe. The carriage comprises locomotive side walls, partition walls, a top cover and an installation chassis. The top cover comprises an air outlet channel, a drainpipe and a manhole. The power battery packs are respectively installed in boxes and the boxes are arranged along carriage length to form several columns. Each column of the boxes are divided into several lines. All the boxes do not contact so that several ventilation sub-channels are formed. All the ventilation sub-channels form a ventilation channel. An air channel port of the ventilation channel is arranged above a position between the each adjacent columns of the boxes. The system has a simple structure, realizes combination of a heat radiation system and a carriage design, is convenient for enforcement and realizes heat radiation cooling through the most simple method based on a power battery pack air channel design.
Description
technical field [0001] The invention relates to the field of rail transportation equipment, in particular to a cooling system for a locomotive power battery pack. Background technique [0002] The power battery pack is an essential power source for hybrid locomotives, and they are currently placed in closed compartments. Due to its huge size, it will generate a lot of heat when charging and discharging, and the closed compartment makes it unable to dissipate heat in a timely and effective manner. Heat buildup can greatly affect battery pack performance, shorten life and create a fire hazard. [0003] At present, there is no design specifically for the heat dissipation of power battery packs for locomotives, and it is imminent to solve this problem. Contents of the invention [0004] In order to solve the above problems, the present invention provides a cooling system for a power battery pack of a locomotive, which includes a compartment box with several power battery pac...
