AI Technical Summary

Technical Problem

In the existing technology, heat exchangers and valves are scattered on the oil cooling circuit, resulting in complex pipeline connections, difficult layout, a large number of parts, large space occupation, and difficult assembly.

Method used

The heat exchange module adopts an integrated solenoid valve. By integrating the water inlet, water outlet, oil inlet, oil outlet, heat exchange pipe, branch pipe and solenoid valve in the housing, it realizes centralized management and flow regulation of cooling oil, reduces connecting parts and improves structural compactness.

Benefits of technology

It reduces the space occupied by heat exchange modules and powertrain, improves cooling efficiency and flow, adapts to temperature regulation requirements under different operating conditions, and ensures the normal operation of the powertrain.

Abstract

A heat exchange module, a power assembly, and an electric vehicle, which relate to the technical field of vehicles, and are used for solving the problem of a heat exchange module occupying a relatively large space. A housing of a heat exchange module (40) is configured to accommodate a heat exchange pipe (007), a branch pipe (008), and a solenoid valve (50). An oil inlet is configured to supply cooling oil to the heat exchange pipe (007) and the branch pipe (008). The heat exchange pipe (007) is configured to use cooling water to exchange heat with the cooling oil flowing through the heat exchange pipe. The branch pipe (008) is configured to supply to an oil outlet the cooling oil that does not pass through the heat exchange pipe. The solenoid valve (50) is configured to adjust the flow rate of the cooling oil in the branch pipe (008). The oil outlet is configured to discharge from the heat exchange module the cooling oil subjected to heat exchange via the heat exchange pipe (007) and the cooling oil that passes through the branch pipe (008) without passing through the heat exchange pipe. The heat exchange pipe, the branch pipe, and the solenoid valve are all accommodated in the heat exchange module, so that connecting members between the heat exchange module and the solenoid valve, between the heat exchange module and the heat exchange pipe, and between the heat exchange module and the branch pipe are eliminated. Therefore, the heat exchange module has a more compact structure and occupies a smaller space.
