The invention discloses a honeycomb-shaped heat transfer device and an application thereof and belongs to the heat pipe heat exchange technology. The honeycomb-shaped heat transfer device comprises a barrel-shaped casing and a center pipeline, wherein the center pipeline is located in the barrel-shaped casing, and sealing space is formed between the inner wall of the barrel-shaped casing and the outer wall of the center pipeline; multiple partition boards are arranged between the inner wall of the barrel-shaped casing and the outer wall of the center pipeline and divide the sealing space into multiple cavities parallel to the center pipeline; the cavities are filled with working media; a plurality of microfins made of heat conduction materials are sequentially arranged on at least one surface of the inner wall of each cavity, and arrayed capillary microgrooves are formed between adjacent microfins and are beneficial to reduction of resistance borne by the working media flowing in the corresponding cavity. The honeycomb-shaped heat transfer device has high industrial application value in the aspects of industrial waste heat recovery, air cooling devices, fluid heating and the like, and has the characteristics of high heat transfer efficiency, low cost, safety and no demand of extra power.
