Abstract
The utility model relates to a battery heat dissipation field. A waterproof type battery liquid cooling ware, includes battery box, waterproof layer, water -cooling board and drainage switch. The battery box is separated two -layerly for from top to bottom by the waterproof layer, battery module places on the upper strata, and the water -cooling board is placed in the lower floor, and battery module and water -cooling be stiff and straight to be connect or contact through heat conduction ware and waterproof layer, and battery module's heat passes through the waterproof layer and conducts on the water -cooling board. The drainage switch is installed in the lower floor, installs water -absorbing expansion material in the drainage switch, can back down the drainage switch by water expansion when taking place the cooling water and leak, makes the cooling water battery box of discharging. Install the leakage sensor in the drainage switch, can leak the state timely feedback with the cooling water and give battery management system. The beneficial effects of the utility model are that, this technical scheme can carry out effectual heat dissipation and water proof to battery module, can automatic open the drainage switch when taking place the cooling water and leak, make the cooling water battery box of discharging, further improve battery module's waterproof performance.
Description
Technical field
The utility model relates to battery field of radiating.
Background technology
New-energy automobile has efficiently, the feature of environmental protection, and useful life of new energy car battery, the feature of environmental protection and security reliability determine quality and the operation conditions of new-energy automobile.Usually, battery often occurs with exothermic reaction in the process of carrying out discharge and recharge, and battery is often very responsive for the change of temperature, the otherness of battery temperature decides useful life and its stability of battery, and the performance of temperature on battery has vital impact.
Water-cooling technology has significant advantage as the efficient heat sink conception of one in battery temperature control, but current technical scheme is generally cooled plate directly contacted with battery module to dispel the heat, there is the risk that cooling water is revealed, cooling water is revealed directly may cause damage to battery.
Applicant proposes a kind of sealing water-cooling method for cooling electronic apparatus and equipment in application 201110132047.X, and battery module can be sealed with water-cooling, not only radiating efficiency is high, and can carry out waterproofing protection to battery module; But the heat dispersion of this technical scheme requires that cabinet wall is thinner, and new-energy automobile power battery requires that battery tank wall is thicker in meet shock-resistant demand for security of Denging, and being applied to new-energy automobile power battery field also needs head it off.
Utility model content
For the watertight reliability solving the heat radiation aspect prior art of new energy car battery is not enough and require higher problem to Battery case security performance; the utility model proposes a kind of water proof type cell water cold heat sink on the basis of application 201110132047.X; cooled plate and battery module are arranged in battery case, and waterproofing protection is carried out to battery module.
The utility model solves the technical scheme that its technical problem adopts:
A kind of water proof type cell water cold heat sink, comprises battery case, watertight composition, cooled plate and drainage switch.Battery case is divided into two-layer up and down by watertight composition, battery module is placed on upper strata, cooled plate is placed on lower floor, battery module and cooled plate are directly or contacted with watertight composition by heat transfer device, heat transfer device is heat pipe for thermal conductivity device or heat-conducting metal block, and the heat of battery module is transmitted in cooled plate by watertight composition.Drainage switch is arranged on lower floor, is provided with water uptake expansion material in drainage switch, imbibition can back down drainage switch, making cooling water discharge battery case when there is cooling water leakage.In drainage switch, leak sensor is installed, cooling water leakage state can be fed back to battery management system in time.
The beneficial effects of the utility model are, the battery case of this technical scheme is divided into two-layer up and down by watertight composition, battery module is placed on upper strata, and cooled plate is placed on lower floor, therefore, it is possible to carry out waterproofing protection to battery module; Directly or contacted with watertight composition by heat transfer device, the heat of battery module is transmitted in cooled plate by watertight composition, can increase the heating surface area of cooled plate, therefore effectively can dispel the heat to battery module for battery module and cooled plate; In drainage switch, water uptake expansion material is installed, imbibition can backs down drainage switch when there is cooling water leakage, making cooling water discharge battery case, therefore further increasing the water resistance of battery module; In drainage switch, leak sensor is installed, cooling water leakage state can be fed back to battery management system in time, enable system take corresponding treatment measures in time, the therefore larger coefficient of safety that improve car load.
