Benefits of technology

This technology helps save fuel by directly circulating some other substances into specific parts within an internal combustion system for better performance.

Problems solved by technology

This technical problem addressed in this patented text relates to improving the efficiency or lifespan (power) capability for an extendable electrical system used with hybrid powertrains that can operate effectively even when exposed during cold temperatures such as winter months without being able to start up quickly due to insufficient coolant flow caused by direct contact between the outside air and the inside components.

Embodiment Construction

[0034] Further detailed explanation through specific implementation mode below:

[0035] Such as figure 1 As shown, this embodiment provides a thermal management system for a battery pack, which includes a battery pack heating circuit and a battery pack heat dissipation circuit. The liquid cooling plate 2 of the channel dissipates heat to the battery pack.

[0036] In this embodiment, the liquid cold plate 2 includes a first cavity 22 and a second cavity 21 that are independent of each other; the liquid cold plate 2 is preferably a harmonica tube, and a part of the harmonica tube channel in the liquid cold plate 2 is the second cavity 21 ; another part of the harmonica tube channel in the liquid cold plate 2 is the first cavity 22 . Such as figure 2 As shown, the multiple harmonica tube channels in the middle of the liquid cold plate 2 in this embodiment are the second cavity 21, and the multiple harmonica tube channels on both sides of the liquid cold plate 2 are the first c

Abstract

The invention belongs to the technical field of battery packs, and particularly relates to a thermal management system of a battery pack. The system comprises an engine heat dissipation loop used for cooling an engine; a motor and electric control heat dissipation loop which is used for cooling the motor and electric control elements; and a liquid cooling plate which is used for adjusting the temperature of the battery pack, wherein the engine heat dissipation loop and the motor and electric control heat dissipation loop are connected to the liquid cooling plate through a reversing valve. According to the technical scheme, the first cooling liquid in the engine heat dissipation loop can be used for collecting waste heat of the engine, or the second cooling liquid in the motor and electric control heat dissipation loop is used for collecting waste heat of the motor and electric control elements, and the first cooling liquid or the second cooling liquid can directly enter the liquid cooling plate to heat battery cells in the battery pack; the utilization rate of waste heat is high, the energy consumption of the whole vehicle can be effectively reduced, and the endurance mileage is increased.
