A temperature regulating valve and a thermal management system provided with the temperature regulating valve are provided. The temperature regulating valve includes a filling state and a first working state, and a thermodynamic element is impelled to not abut against a first valve seat by means of providing a hot melt in an end cover of the temperature regulating valve. When a first valve port is in an open state, at said time the temperature regulating valve is installed in the thermal management system, and since the first valve port is in the open state, lubricating oil may then flow into a heat exchange device by means of a first interface channel, the first valve port, and a second interface channel during a process of filling the lubricating oil.

Temperature regulating valve and thermal management system provided with temperature regulating valve

A valve assembly, a heat exchange assembly, and an oil temperature regulation system for a gearbox. The heat exchange assembly includes a heat exchange core body, the valve assembly, an adapter, and a mounting plate fixed to the heat exchange core body. The valve assembly is disposed at a second channel of the heat exchange core body or partially located at the second channel. The valve assembly is provided with a first valve port and a first notch. The heat exchange core body includes a through channel that is in communication with a fourth port.

Valve assembly, heat exchange assembly, and oil temperature regulation system for gearbox

A heat exchanger including a temperature control assembly and a heat exchange assembly is disclosed. A heat exchange channel is formed within the heat exchange assembly. A branch channel arranged in parallel with the heat exchange channel is provided within the heat exchanger. The heat exchanger has a liquid inlet and a liquid outlet. The temperature control assembly includes a valve body. A valve cavity in communication with the liquid inlet is provided in the valve body. A gap and a second valve port are provided at a peripheral wall of the valve body. An annular protrusion is provided on an inner wall of the valve cavity. The valve body is provided with a valve core and a drive component therein.

Heat exchanger with internal thermal valve

A thermostatic valve includes a valve body formed by die casting. The valve body includes: a valve main body forming a valve cavity; a plurality of connection tube portions; and installation base portions adjacent to the connection tube portions. Each of the connection tube portions includes a straight tube section connected to the valve main body. A reinforcement member is provided between the straight tube section of the connection tube portion and the installation base portion adjacent to the connection tube portion. The valve body is formed by die casting, and respective parts of the valve body can be processed according to actual size requirements with no redundant material, thereby realizing a light weight of the thermostatic valve. Providing the reinforcement member satisfies a strength requirement when using die casting.

Thermostatic valve

A heat exchange device includes a heat exchanger body and a thermostatic assembly; the heat exchanger body includes a first passage, one end of the first passage is in communication with the fluid inlet of the heat exchanger body, at least part of the thermostatic assembly is arranged in the first passage, the thermostatic assembly comprises a valve body provided with a valve chamber, the valve body is provided with an inlet, a first outlet, and a second outlet which are all in communication with the valve chamber; a return spring, a shape memory alloy spring, and a valve sleeve are provided in the valve chamber, the valve sleeve is slidable back and forth in an axial direction, the shape memory alloy spring is made of a memory alloy material, and the return spring and the shape memory alloy spring are respectively located on two sides of the valve sleeve.

Heat exchange device with shape memory alloy spring

Provided is a thermostatic valve including a first valve body, a second valve body, a third valve body, a first thermal actuator, a second thermal actuator, a valve core, a first valve port, a second valve port and a third valve port. The first valve body includes a second cavity and a third cavity. The second thermal actuator is sealedly fixed in the first valve body to isolate the second cavity from the third cavity. At least a part of the valve core is located in the second cavity. The valve core is connected to, or is integrated with, or abuts against a second valve stem of the second thermal actuator. The second thermal actuator is configured to act in response to a change in temperature of a fluid in the third cavity. The valve core is configured to open the second valve port or the third valve port in response to an action of the second valve stem.

Temperature thermostatic valve

Thermal bypass valve

A thermostatic valve, including: a valve body having a cavity provided therein; an end cover, a thermal actuator and a first spring which are provided in the cavity. The end cover is provided with a first valve seat; the first valve seat is provided with a first valve port; the first valve port is provided opposed to a second port, and the first valve seat encloses an inner end opening of the second port; an outer wall of the first valve seat enclosing the inner end opening of the second port is in clearance fitting with an inner wall of the cavity; an outer wall at an end of the body of the thermal actuator which is near the end cover is in slide fitting with an inner wall of the valve seat; the thermostatic valve opens and closes the first valve port by means of the body of the thermal actuator.

A thermostatic valve is provided according to the present application. In the thermostatic valve, a relief ring movable upward and downward is provided in a cavity of a valve body. Under normal conditions, the relief ring abuts against a step on an inner wall of the cavity or another fixing portion via an elastic element, and the cavity is further provided therein with a first passage which can be opened or closed by upward or downward moving of the relief ring. In the case that the fluid pressure in the thermostatic valve is excessively large, the fluid can push the relief ring to compress the elastic element, thus the first passage in the relief ring is opened, and the first flow passage and the third flow passage may simultaneously allow circulation of the fluid, thereby may prevent damage caused by an excessively large fluid pressure in the thermostatic valve.
