Benefits of technology

The patent describes a surface coating layer for heat exchangers that can reduce the formation of frost and quickly remove any formed frost to improve heat exchange efficiency. The coating layer is made up of multiple layers, including a first layer that has high thermal conductivity and a second layer that has a low contact angle with water. The first layer is made of a composite of a matrix and a nanobody, while the second layer is made of a composite of a matrix and a nanobody. The nanobodies can be nanotubes, nanofibers, nanowires, nanoparticles, nanospheres, or a combination of these. The surface coating layer can have a thickness of 0.5 μm to 100 μm and can be used on a variety of heat exchangers.

Problems solved by technology

Since the surface temperature of the heat exchanger drops below the freezing point of water during operation, frost may form on the surface of the heat exchanger especially where hot moist air passes through the heat exchanger.
The formation of frost on the heat exchanger may disturb air flow and heat transfer of the air in a cooling tube, thus decreasing heat exchange efficiency.

Abstract

A surface coating layer, in contact with a surface of a base material of a heat exchanger, comprises a plurality of composite layers comprising a first layer contacting a surface of the base material, the first layer comprising a first matrix and a first nanobody, and a second layer contacting a surface of the first layer and having an interface with the air, where the first layer and the second layer each include a different amount by volume of the first nanobody and the second nanobody, respectively.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Korean Patent Application No. 10-2011-0003676, filed Jan. 13, 2011, and all the benefits accruing therefrom under 35 U.S.C. 119, the content of which in its entirety is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002](a) Field of the Invention[0003]A surface coating layer and a heat exchanger including the surface coating layer are provided.[0004](b) Description of the Related Art[0005]A cooling device such as a refrigerator or a freezer lowers the temperature by repetition of the cooling cycle of compression-condensation-expansion-evaporation of a coolant, such as a fluid refrigerant which may be a liquid, gas, or a combination of these in equilibrium. The cooling device operates by increasing the temperature and pressure of the coolant from a low temperature and low pressure to a high temperature and high pressure, condensing the coolant under high temperature and high pressure by air...
