Heat pipe with discrete heat transfer property is often called thermal superconductor because it has extremely large thermal conductivity. This special heat transfer property is destroyed by integrating cooling apparatus and further reducing the cooling power of a heat pipe cooler. This paper experimentally studied the heat transfer property of heat pipe influenced by integrated cooling apparatus. To simplify the investigating process, a home-made square heat pipe with the dimensions of L×W×H=10×10×100 mm3 was built with two pieces of copper plates and two pieces of glass plates face to face, respectively. The two pieces of copper plates were constructed with inside walls of capillary structure and the two pieces of glasses were with antifog inside walls for observing the inner phenomenon. Moreover, isothermal circulating cooling water was applied outside the heat pipe instead of cooling fin. The results show that heat vapor in the heat pipe is condensed earlier and cannot reach the remote section of condenser. In other words, the heat transfer property of heat pipe is destroyed by integrating cooling water. This phenomenon causes the unfavorable cooling power of the heat pipe cooler.

To choose the suitable heat insulating material for refrigerated cargo hold shipboard of fishing vessel, a steady state three-dimensional mathematical model of heat transfer is developed in this paper. The heat-transfer model is simplified reasonably in order to facilitate analyzing and solving. After defining the boundary conditions of the model according to the heat-transfer process of the shipboard, numerical simulations with different heat insulating material are performed using computational fluid dynamics (CFD) software PHOENICS. The obtained temperature distributions of the model in each case are analyzed. The suitable one is pointed out according to the degree of influence of the heat insulating material on heat-transfer property of the shipboard.

Aerated Concrete

In this paper, a new type of warming compound blocks with slag concrete was designed and prepared. The effect of specification, hole pattern and form of warming compound blocks on the thermal property of the blocks was researched. The results show that, with the addition of slag, EPS and aerated concrete, the thermal property will be improved greatly. The thermal resistance of warming compound blocks with three rows of EPS would reach 1.13 m2•K/W, and the thermal resistance of warming compound blocks with three rows of aerated concrete would reach 0.83 m2•K/W.

The heat transfer property of double skin façade’s façade was analyzed and summarized from the façade’s ventilation pattern, shading mode, cavity width, cavity height, vent openings, the glass optical property and its sequence and convection methods. It showed that the analysis of double skin facade should employ various research methods on the basis of dynamic analysis and comprehensively take multiple factors into consideration on the grounds of actual situation for which may have effects on the heat transfer property of curtains. As a result, more double skin façade with a higher performance of heat transfer can be invented.
