The invention relates to the technical field of temperature control devices, in particular to a thermostat, a cooling system and a vehicle. A first passage, a second passage, a third passage and a fourth passage are arranged in the thermostat; a second passage is additionally arranged in the thermostat, so that the radiator can be preheated when small circulation is executed at low temperature; and a fourth passage is additionally arranged inside, so that automatic pressure relief is performed in a high-pressure state. The thermostat solves the problems that an existing thermostat is single in function, low in integration level and only capable of controlling opening and closing of small circulation and large circulation of an oil way, and meanwhile the reliability of a heat dissipation system is affected due to the fact that high-temperature oil is large in heat impact and pressure impact on a radiator when the large circulation is opened. And meanwhile, when the system pressure is too high, the pressure cannot be released in time.

    本发明涉及温控装置技术领域,特别涉及一种节温器及散热系统与车辆,所述节温器内设置有第一通路、第二通路、第三通路与第四通路;节温器通过内部增设第二通路,在低温执行小循环时可对散热器进行预热;还通过内部增设第四通路,在高压状态进行自动泄压。本发明的提出解决了现有的节温器功能单一,集成度低,仅可控制油路小循环与大循环的开启和关闭的问题,同时在大循环开启时高温油对散热器的热冲击、压力冲击较大,影响散热系统的可靠性的问题,同时在系统压力过高时无法及时泄压的问题。
