Embodiment Construction
[0031] Obtain nano-TiO by the above method 2 -SiO 2 -Al 2 o 3 - After the ZnO / fluoroacrylic acid composite emulsion, comb the condenser fins neatly, use an air gun to blow off the dust on the surface, then immerse in the prepared composite emulsion, pick it up after 3 seconds and dry it in an oven at 100 degrees, heat The time lasts for 5 minutes, so that the condenser fins are attached to the composite emulsion, and a hydrophobic nano-coating is formed on the condenser fins.
[0032] Nano-TiO in Hydrophobic Nanocoatings Formed on Condenser Fins 2 It can absorb a large amount of ultraviolet rays and enhance the weather resistance of the coating; on the other hand, because nano-TiO 2 The presence of the coating surface greatly increases the contact angle with water, showing super-hydrophobicity, and its surface has the characteristics of waterproof and anti-fouling.
[0033] In addition, SiO in the coating 2 It can achieve the purpose of anti-ultraviolet aging and heat ag...

The present invention provides an air conditioner outdoor machine condenser comprising fins, a hydrophobic coating layer is covered on the fin. The coating layer has super strong hydrophobicity, so that the no water accumulation is on the air conditioner condenser surface, the frost depositing degree of the air conditioner outdoor machine condenser when heating can be effectively alleviated and prevented, sea air humid gas can not pasted on the fin surface, the corrosion of saline matter can be effectively prevented; moreover, the hydrophobicity of the material can enable the coating layer onthe condenser fin to generate a weathered layer of few micrometer thickness, namely the des-powdering phenomenon, under the actions of wind and rain water, the old weathered layer can fall off, a newcoating layer is exposed, the self-cleaning function can be implemented; meanwhile, the hydrophobicity can enable the anti-dirt characteristic of the air conditioner outdoor machine condenser to be improved obviously, so that the dust granule can be adhered on the coating layer surface in the suspending state, the dust granule and the coating layer surface acting forces are reduced greatly, few dust ashes are adhered on the coating layer surface, the heat exchanging performance of the condenser can be kept.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, in particular to the coating used on the fins of the condenser of the air conditioner. Background technique [0002] The heat exchange performance of the condenser of the outdoor unit of the air conditioner directly affects the working performance of the air conditioner. The condenser is composed of copper tubes and aluminum fins parallel to the copper tubes. The schematic diagram of the fins is as follows: figure 1 shown. [0003] Most of the existing air-conditioning outdoor unit condensers use a hydrophilic coating. Due to the harsh weather environment, dust and dirt of the outdoor unit, the hydrophilic coating will lose its hydrophilicity in a short period of time, resulting in The heat exchange efficiency of the condenser plummets, and the performance of the air conditioner also decreases. [0004] In order to solve the problem of cleaning the coating on the condenser of the outdo...
