The invention belongs to the field of aero-engine heat exchange, and particularly relates to a uniform-temperature rectifying support plate hot air anti-icing structure based on convective heat transfer, which comprises a cavity, the cavity is provided with a first partition plate and a second partition plate, and the first partition plate and the second partition plate divide the cavity into a support plate front cavity, a support plate rear cavity and a support plate middle cavity respectively. The top ends of the support plate front cavity and the support plate middle cavity are provided with air inlets for introducing heat flow, the bottom ends of the support plate front cavity and the support plate middle cavity are communicated with the support plate rear cavity, and the support plate rear cavity is provided with a plurality of exhaust holes; the first partition plate between the support plate front cavity and the support plate middle cavity is provided with a plurality of through holes distributed in the flowing direction of heat flow; and the root of the front cavity of the support plate is provided with a throttling hole, and the central axis of the throttling hole falls into the front cavity of the support plate, so that the problem of non-uniform temperature distribution of the support plate caused by on-way temperature drop of heat flow is solved, and the non-uniformity of temperature distribution of the anti-icing structure is reduced.
本申请属于航空发动机热交换领域,特别涉及一种基于对流换热的均温性整流支板热气防冰结构,包括:所述结构具有空腔,所述空腔具有第一隔板与第二隔板,第一隔板与第二隔板分别将所述空腔分隔成支板前腔、支板后腔以及支板中腔,支板前腔与支板中腔在顶端具有通入热流的进气口,支板前腔与支板中腔在底端与支板后腔联通,支板后腔具有多个排气孔;其中,支板前腔与支板中腔之间的第一隔板具有多个沿热流流动方向分布的通孔;支板前腔根部具有节流孔,所述节流孔的中轴线落入支板前腔中,申请克服了热流沿程温降导致的带来的支板温度分布不均匀的问题,减少了防冰结构温度分布的不均匀性。
