Water-cooled radiator for battery

Abstract

The invention relates to the radiating field of batteries. The water-cooled radiator for a battery comprises a battery box, a water-cooled plate, a waterproof rubber ring, a heat conducting silicon rubber mat and a drainage switch; the water-cooled plate is the water-cooled plate based on a porous flat pipe; an open pore is formed in the side wall of the battery box to allow the water-cooled plate to penetrate through the battery box; the middle part of the water-cooled plate is arranged in the internal of the battery box; the two ends, including welded joints, of the water-cooled plate are arranged in the external of the battery box; the gap between the water-cooled plate and the open pore in the side wall of the battery box is filled by the waterproof rubber ring; the drainage switch is mounted on the wall of the battery box; a water swelling material is mounted in the drainage switch, and capable of jacking up the drainage switch by water expansion in cooled water leakage so as to discharge the cooled water out of the battery box. The water-cooled radiator for the battery has the beneficial effects that: the technical scheme of the water-cooled radiator can perform effective thermal dissipation and waterproof protection on battery modules; and the drainage switch can be opened automatically in cooled water leakage to discharge the cooled water out of the battery box, so that the waterproof performance of the battery module is further improved.

Description

technical field [0001] The invention relates to the field of battery heat dissipation. Background technique [0002] New energy vehicles have the characteristics of high efficiency and environmental protection. The service life, environmental protection, safety and reliability of new energy vehicle batteries determine the quality and operating status of new energy vehicles. Usually, the battery is often accompanied by an exothermic reaction during the charging and discharging process, and the battery is often very sensitive to temperature changes. The difference in battery temperature determines the service life and stability of the battery, and the temperature has an impact on the performance of the battery. crucial impact. [0003] As an efficient heat dissipation solution, water cooling technology has significant advantages in battery temperature control. However, the current technical solution generally installs the water cooling plate in the battery box and directly co...
