Problems solved by technology

When the vehicle is running normally, the lubricating oil can usually meet the needs of vehicle lubrication, but when the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, and the vehicle is driving under the transient slipping condition of the torque converter, then May cause the gearbox to overheat, causing the oil to lose its lubricating properties

Embodiment Construction

[0031] A lot of research has been done on the factors affecting the response speed of the thermostat. The research found that the thermodynamic element of the thermostat is based on the thermal expansion and contraction of the fluid when the heat-sensitive substance feels the temperature. From the temperature of the thermal-sensitive substance to the thermal expansion and contraction and then to the spring force, it takes a certain response time, that is, the thermal The response time of the moving element is slow, which will cause a certain hysteresis in the temperature of the lubricating oil, seriously affecting the performance of the transmission, and even damaging the transmission.

[0032] In addition, the thermodynamic element has a large volume and needs to cooperate with a spring to realize the switching of the flow path, so the volume of the thermostat is relatively large. Therefore, when the thermostat is installed in the system, it usually needs to be connected to t...

Abstract

The invention discloses a heat exchange device. The heat exchange device includes a heat exchanger body and a temperature adjustment assembly. When the temperature of the oil flowing into a valve chamber is greater than or equal to a predetermined temperature, the elastic potential energy of the memory spring of the temperature adjustment assembly When activated, the oil enters the heat exchange channel for heat exchange, otherwise, the oil directly flows out of the heat exchanger body through the bypass channel without passing through the heat dissipation component; the thermal response of the memory spring is fast and the response time is short, which greatly improves the performance of the transmission And the safety of use; and the memory spring is small in size and relatively high in installation stability. It does not need to be used in conjunction with other components, simplifies the structure of the temperature adjustment component, and greatly reduces the volume of the temperature adjustment component. The temperature adjustment component can be installed on the plate replacement The position of the fluid inlet of the heater is integrated with the design, so that no on-site installation is required, the installation efficiency is improved, and the occupation of the vehicle space is greatly reduced, which is conducive to optimizing the vehicle design.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange device. Background technique [0002] The heat exchange device can realize the transfer of heat between two media, and it is mainly used in the system that needs to adjust the temperature of the working fluid in the system, so that the temperature of the working fluid in the control system is in the normal temperature range and meets the normal working requirements of the system . [0003] For vehicles, the normal lubrication of the working parts of the vehicle by lubricating oil is the key to the safe driving of the vehicle. When the vehicle is running normally, the lubricating oil can usually meet the needs of vehicle lubrication, but when the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, and the vehicle is driving under the transient slipping condition of the torque converter, then It may cause the gearbox tempe...
