Title:
ENERGY-STORAGE-TYPE ENERGY RECOVERY AND NOISE REDUCTION DEVICE FOR HYBRID ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/012392
Kind Code:
A1
Abstract:
Disclosed is an energy-storage-type energy recovery and noise reduction device for a hybrid electric vehicle. The device comprises a heat storage system, thermoelectric conversion systems, a heat superconducting plate (1), and a silencer (7), wherein the heat storage system comprises heat storage box bodies (8), heat storage materials (2), and heat conduction fins (3); the heat storage box bodies (8) surround the outer side of the silencer (7); the heat storage materials (2) fill the heat storage box bodies (8); the heat conduction fins (3) are arranged in the heat storage materials (2); a plurality of thermoelectric conversion systems are provided, and same are distributed on the surfaces of the heat storage box bodies (8) in a surrounding manner along the axis of the silencer (7); each thermoelectric conversion system comprises heat dissipation fins (4) and thermoelectric power generation pieces (5); the cold end and the hot end of each of the thermoelectric power generation pieces (5) are respectively attached to the heat conduction fins (3) and the heat dissipation fins (4) adjacent thereto; and an evaporation section of the heat superconducting plate (1) is arranged inside the silencer (7), and a condensation section of the heat superconducting plate (1) is arranged inside the heat storage materials (2). The device is used for recovering tail gas heat by means of the advantages of the heat superconducting plate, i.e. high heat transmission capacity, high shape adaptability, and high latent heat of phase change materials. The temperature of vehicle tail gas is reduced, and the ability of a silencing system to silence medium-and-low-frequency noise is improved.
