THERMOELECTRIC GENERATION DEVICE

PROBLEM TO BE SOLVED: To provide a thermoelectric generation device which improves power generation efficiency.SOLUTION: A thermoelectric generation device (1A) comprises: a thermoelectric element (2) with one face thereof installed on a heating section (3) and the other face thereof on a cooling section (4); and a heat transfer pipe (6) arranged in a flow passage (5) where high temperature fluid flows therein. The heating section (3) and the heat transfer pipe (6) respectively have inner spaces (9a and 9b) which are communicated with each other. The inner space (9a) of the heating section (3) and the inner space (9b) of the heat transfer pipe (6) form a circulation route (9) where a heat medium is circulated therein. An outlet (6b) of the heat transfer pipe (6) through which the heat medium flows out thereof is arranged at a position higher than an inlet (6a) of the heat transfer pipe (6) through which the heat medium flows thereinto. The inlet (6a) of the heat transfer pipe (6) is arranged at a position lower than a lowest section of the thermoelectric element (2). The heat transfer pipe (6) evaporates the heat medium flowing in the circulation route (9) using heat of the high temperature fluid. The heating section (3) condenses the evaporated heat medium.SELECTED DRAWING: Figure 1 【課題】発電効率を向上させる熱電発電装置を提供する。【解決手段】本発明の熱電発電装置（１Ａ）は、一方の面を加熱部（３）に設けると共に他方の面を冷却部（４）に設ける熱電素子（２）を備える熱電発電装置であって、高温流体が流れる流路（５）に配置される伝熱管（６）を備え、加熱部（３）と伝熱管（６）とは、それぞれ互いに連通する内部空間（９ａ、９ｂ）を有し、加熱部（３）の内部空間（９ａ）と伝熱管（６）の内部空間（９ｂ）とは、熱媒体が循環する循環経路（９）を形成し、熱媒体が排出される伝熱管（６）の出口（６ｂ）は、熱媒体が流入する伝熱管（６）の入口（６ａ）よりも高い位置に設けられ、伝熱管（６）の入口（６ａ）は、熱電素子（２）の最下端部より低い位置に設けられ、伝熱管（６）は、高温流体の熱を利用して、循環経路（９）を流れる熱媒体を蒸発させ、加熱部（３）は、蒸発した熱媒体を凝縮する。【選択図】図１
