Battery temperature control device and battery temperature control system

Abstract

Provided are a battery temperature control device and a battery temperature control system, having excellent heat-transfer efficiency and uniformity of temperature controlling ability, and being configured such that an increase in mass and power consumption can be prevented. The battery temperature control device and the battery temperature control system each comprise a battery having a battery cell, a heat conduction member thermally connected at one extremity portion thereof to the battery, and condenser fins and / or an evaporator thermally connected to the heat conduction member at the other extremity portion thereof.

Description

technical field [0001] The present invention relates to a battery temperature regulating device and a battery temperature regulating system that use a heat conducting member to transport the heat released from a battery to a fin of a condenser and / or an evaporator. Background technique [0002] As a conventional battery temperature control system, a system has been proposed that includes: a battery installed in a vehicle for driving; a blower that generates air blown to the battery provided separately from the blower for an air conditioner in the vehicle compartment; A heat exchanger installed separately from the heat exchanger for the air conditioner in the cabin to cool the blown air through heat exchange between the refrigerant flowing inside and the blown air sent to the battery, and the evaporator as a heat exchanger and the In-cabin air conditioners share refrigerant (Patent Document 1). [0003] However, in Patent Document 1, there is a problem that although the batt...

Problems solved by technology

[0003] However, in Patent Document 1, there is a problem that although the battery is cooled by supplying the air cooled by the refrigerant to the battery, the heat transfer efficiency is insufficient due to the passage of the air.

Furthermore, in Patent Document 1, there is also the following problem: it is difficult to make the air flow uniform, so due to the difference in the path of the air (for example, the difference between the upstream side and the downstream side of the air flow), air flow to each battery cell (battery cell) constituting the battery ) The temperature of the air supplied will vary, so that the cooling of the battery takes time and the temperature of the battery cells will fluctuate

[0008] However, in the system of Patent Document 3 in which the same cooling system core is provided and cooling is performed, the mass of the vehicle and the power consumption for cooling the refrigerant increase, so there is still a problem that the running distance of the vehicle becomes shorter.
