HEAT TRANSFER DEVICE

摘要

A heat transfer device capable of promoting a heat transfer effect while limiting an increase in the pressure loss of heat carrying fluid in a heat exchanger where an air current velocity is set to a comparatively low level. A plurality of vertical vortex generating blades (10) are arranged in a span direction on each side of a heat transfer body (T). Vertical vortex generating blades are oriented in the substantially same direction so as to deflect heat carrying fluid (A) to the same direction to guide the heat carrying fluid to the rear region of the heat transfer body. Each vertical vortex generating blade has a profile of gradually decreasing in its height toward the upstream side in the heat carrying fluid. The heat carrying fluid flowing to the rear while running over a plurality of vertical vortex generating blades forms a plurality of vertical vortexes in the rear of the vertical vortex generating blades.
