Bamboo joint type oil-pressure uniform-temperature heating device and method

The invention provides a bamboo joint type oil-pressure uniform-temperature heating device and method. The bamboo joint type oil-pressure uniform-temperature heating device comprises heat dissipation cavities, three annular heating joint blocks, a heat dissipation pipeline, annular heating joint cavities, fixing bolts and spherical spacers. The three annular heating joint blocks of the same size are mounted on the heat dissipation pipeline. Each annular heating joint block is matched with the heat dissipation pipeline to form one annular heating joint cavity, and the flow volumes of the three annular heating joint cavities are the same. The distances between every two annular heating joint blocks are equal, so that the heat dissipation cavities with equal volumes are formed, and the annular heating joint blocks and the heat dissipation pipeline are connected and combined through the fixing bolts and the spherical spacers to form a bamboo joint type component. Oil generates heat according to power losses of th
