Embodiment

[0032] An integrated double-chamber liquid storage tank for new energy vehicles, including an upper shell 1, a lower shell 2, a pressure cover 3, a pressure cover 4, a first air return port 5, a second air return port 6, and a third air return port. Air return port 7, No. 1 water supply port 10, No. 2 water supply port 11, No. 3 water supply port 12, No. 1 overflow port 13, No. 2 overflow port 14, No. 1 bracket 8, No. 2 bracket 9, No. 3 bracket 17 .

[0033] The upper and lower shells are two injection molded shells, the upper shell 1 is provided with two cavities, the lower shell 2 is provided with two cavities corresponding to the positions of the cavities of the upper shell, and the upper shell The two cavities are connected by connecting ribs, and the two cavities of the lower shell are also connected by connecting ribs. After the upper and lower shells are welded by a hot plate, the upper and lower cavities are butted to form two completely independent cavities. That is,...

Abstract

The invention discloses an integrated double-cavity liquid storage tank for a new energy vehicle. The integrated double-cavity liquid storage tank for the new energy vehicle comprises an upper shell and a lower shell, the upper shell and the lower shell are each provided with two independent cavities, and after the upper shell and the lower shell are welded through a hot plate, the cavities of theupper shell and the lower shell are in butt joint to form two independent liquid storage cavities; a pressure cover is assembled at the top of each of the two liquid storage cavities; the two liquidstorage cavities are respectively provided with an overflow port, an air return port and a water replenishing port; the integrated double-cavity liquid storage tank is connected with a whole vehicle through a support. By means of the structure, water supplementing of 2-3 cooling circulation loops, exhausting of residual air in the system and stabilization of system pressure can be achieved, the structure is simple, implementation is easy, the arrangement space is saved, assembling is convenient, and cost reduction and light weight are achieved.

Description

technical field [0001] The invention belongs to the technical field of cooling of new energy vehicles, and in particular relates to an integrated double-chamber liquid storage tank for new energy vehicles. Background technique [0002] The automotive cooling system needs a liquid storage tank to achieve water replenishment, exhaust residual air in the system and stabilize the system pressure. [0003] Traditional fuel vehicles only have one cycle of engine cooling, so only one liquid storage tank is needed, while new energy vehicles have more than two cooling cycles including engine cooling, motor cooling, battery cooling, warm air, etc., which requires More than two reservoirs. [0004] With the rapid development of new energy vehicles, as well as the increasingly compact and lightweight requirements of the cabin layout of automobiles, the traditional design of split double liquid storage tanks or even three liquid storage tanks can no longer meet the requirements.
