Heat dissipation system of amphibious armored vehicle

Abstract

The invention discloses a heat dissipation system of an amphibious armored vehicle, and belongs to the technical field of vehicle heat dissipation. The heat dissipation system comprises three-path circulations of a fresh water path, a seawater path and an oil path, and the three-path circulations are separately circulated through a fresh water pump, a seawater pump and an oil pump to drive coolingmedia to circulate; under the land working condition, the fresh water path circulation and the oil path circulation work simultaneously, and the seawater path circulation does not work; and under theoffshore working condition, the fresh water path circulation, the oil path circulation and the seawater path circulation work simultaneously. The fresh water path circulation is provided with an expansion water tank which is used for balancing the pressure of the system water side and the exhaust and water supplement of the system. According to the heat dissipation system, the heat sources of thevehicle are classified according to different cooling media, then heat dissipation components are circularly built according to the characteristics of the marine and onshore double working conditionsof the vehicle, and the heat dissipation requirements of a high-power-density engine and advanced transmission can be met.

Description

technical field [0001] The invention relates to a heat dissipation system for an amphibious armored vehicle, in particular to a heat dissipation system for an amphibious vehicle equipped with a high power density engine and equipped with dual working conditions on land and sea. Background technique [0002] Amphibious armored vehicles are important equipment for amphibious landing operations. According to the current tactical needs, amphibious vehicles with compact structure and strong power have become a development trend. The application of technologies such as high-power-density engines and advanced transmissions has brought about diversification of heat dissipation requirements. At the same time, the dual working conditions of vehicles at sea and on land have also brought huge challenges to the design of heat dissipation systems.

AI Technical Summary

Problems solved by technology

[0003] Currently equipped amphibious armored vehicles, the engine water jacket is used in series with the oil cooler and water radiator. Due to the limited lift of the onboard water pump, the resistance of the engine water jacket is too large, resulting in the system allowing too small external water resistance. The limited assembly space brings great difficulties to the design of secondary heat exchange elements and connecting pipelines; in addition, in traditional cooling systems, the onshore radiator and the offshore radiator are generally connected in different cycles. Sea-land conversion device, the system layout is more cumbersome and the operation is more complicated
