Abstract
An aerodynamic element of a turbomachine including a body extending according to a radial main direction and a radial end located at a radial end of the body. The aerodynamic element further includes a heat exchanger between an internal fluid of the turbomachine and an airflow flowing around the body of the aerodynamic element. The heat exchanger includes a heat pipe in which a working fluid circulates and as well as an evaporation portion in which the working fluid exchanges heat with the internal fluid and a condensation portion in which the working fluid exchanges heat with the airflow.

A turbomachine aerodynamic element including a body extending according to a radial main direction and a radial end located at a radial end of the body,
- the aerodynamic element further including a heat exchanger between an internal fluid of the turbomachine and an airflow flowing around the body of the aerodynamic element, wherein the heat exchanger includes a heat pipe in which a working fluid circulates and comprising an evaporation portion in which the working fluid exchanges heat with the internal fluid and a condensation portion in which the working fluid exchanges heat with the airflow,
- wherein the condensation portion includes cooling tubular fins which are in fluid communication with the vapour pipe, which open into a recuperator and in which the working fluid circulates.
