Problems solved by technology

When filling the thermal management system with lubricating oil, in order to allow part of the lubricating oil to be injected into the heat exchange device, it is necessary to fill in high-temperature lubricating oil so that part of the lubricating oil can be injected into the heat exchange device, so the current filling process of transmission oil is relatively complicated
If the temperature of the filled lubricating oil is not enough, the lubricating oil will not be injected into the heat exchange device, which will lead to insufficient lubricating oil in the thermal management system. For example, during normal use, a part of the lubricating oil will stay in the heat exchange device and In the connecting pipeline, the amount of lubricating oil in the gearbox will be insufficient

Abstract

The invention discloses a thermostatic valve. The thermostatic valve has a first state and a first operating state. A hot melted material is arranged in an end cover of the thermostatic valve. in thefirst state, the hot melted material is in a solid state, and one end of a valve rod abuts against the hot melted material. Through arrangement of the hot melted material, a thermal dynamic element does not abut against a first valve seat, and a first valve port is opened. At the moment, the thermostatic valve is mounted in a thermal management system, the first valve port is opened, and in the lubricating oil charging process, lubricating oil can pass through a first interface channel, the first valve port and a second interface channel to flow into a heat exchange device. The thermal management system is simple in lubricating oil charging and also has the leakage detection function on the heat exchange device and a connecting pipe of the heat exchange device in the lubricating oil charging process.

Description

technical field [0001] The invention relates to the field of fluid control, in particular to a temperature regulating valve and a thermal management system with the temperature regulating valve. Background technique [0002] When the car is running, the parts need to be lubricated with lubricating oil in time to ensure the normal operation of the car, including transmission oil, which mainly realizes the temperature regulation function through the thermal management system. When the temperature of the transmission oil circuit rises, the heat-sensitive material of the thermodynamic element in the thermostat valve expands due to heat, and the channel through which the transmission oil in the thermostat valve directly flows back to the gearbox is blocked or the flow rate of the channel decreases. The high-temperature oil enters the heat exchange device through the temperature regulating valve to cool down and then flows back to the gearbox. Conversely, when the oil temperature...
