AI Technical Summary

Technical Problem

When the heat exchanger of existing drone engines works in a closed case, the heat dissipation efficiency decreases, resulting in a shortening of the engine working time. It is urgent to improve the heat exchange efficiency to extend the engine working time.

Method used

The structure with a positioning plate and a heat exchange plate is adopted, and the heat exchange medium is driven to circulate and flow through a water pump, and the heat exchange plate is driven to separate through the drive member under the support to form an airflow channel and enhance the cooling effect; at the same time, the arc-shaped air guide surface is used to reduce air resistance and ensure stable connection.

Benefits of technology

The cooling speed of the heat exchange medium is improved, the heat dissipation efficiency of the engine is enhanced, and the working time of the engine is extended.

Abstract

The utility model discloses an engine heat exchanger with high exchange rate, which comprises a heat exchange box used for being connected with an engine, a positioning plate and a plurality of heat exchange plates, the heat exchange box is filled with heat exchange media and used for exchanging heat with the engine, the positioning plate is positioned at the lower end of the heat exchange box and is communicated with the heat exchange box, and the heat exchange plates are arranged in the heat exchange box. The positioning plate is provided with a water pump used for driving the heat exchange medium to circularly flow between the heat exchange box and the positioning plate, a support is fixedly arranged at the upper end of the positioning plate, the multiple heat exchange plates are vertically arranged and move in a reciprocating mode in the direction close to or away from the positioning plate, and the support is provided with a driving piece used for driving the heat exchange plates to be close to or separated from each other. The positioning plate and all the heat exchange plates are hollow, conveying pipelines are communicated between the positioning plate and all the heat exchange plates, and after entering the positioning plate, a heat exchange medium circularly flows between the heat exchange plates and the positioning plate along the conveying pipelines. The engine has the effects of improving the heat exchange efficiency of the heat exchanger and prolonging the working time of the engine.
