Heat-pump water heater titanium evaporator and manufacturing method thereof

Abstract

The invention discloses a heat-pump water heater titanium evaporator and a manufacturing method thereof. The heat-pump water heater titanium evaporator comprises evaporation pipes and fins, wherein titanium coatings are coated on the fins, each titanium coating is mainly composed of nanometer titanium dioxide, nanometer silver nitrate, polymeric dispersants and adhesives, and the nanometer titanium dioxide is processed through surface organic and inorganic compound film wrapping. Due to the facts that the titanium coating is mainly composed of anatase nanometer titanium dioxide, and the nanometer titanium dioxide is processed through surface organic and inorganic compound film wrapping, various organics attached to the surfaces of the coatings can be dissolved and removed, and therefore a heat exchanger has long-term stable antibiosis and mildew removing effects, and the problem that in an existing heat-pump water heater, heat exchanging property is affected by dust and bacterium which are easily generated on the fins of the evaporator is solved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning components, in particular to a titanium evaporator of a heat pump water heater and a preparation method thereof. Background technique [0002] As we all know, the evaporator of the heat pump water heater is one of the core components, and its heat exchange effect directly affects the efficiency of the heat pump water heater for making hot water. The evaporator consists of an evaporating tube and an aluminum foil that is in tight contact with the tube wall. The traditional evaporator does not have the functions of sterilization and descaling. Usually, after a period of use, the surface of the main engine evaporator is prone to be full of dirt or moldy and hairy, forming a bacterial bed. Its harm can be imagined. This is because most of the hosts of heat pump water heaters on the market use ordinary hydrophilic aluminum foil. Ordinary hydrophilic aluminum foil has only a certain degree o...

Problems solved by technology

Ordinary hydrophilic aluminum foil has only a certain degree of hydrophilicity and does not have the function of self-cleaning

Moreover, after the ordinary hydrophilic aluminum foil is used for a certain period of time, the hydrophilicity will decrease due to the surface covered with dirt and dust, so the fluidity of water on its surface will also decrease, and the accumulated water bridge will increase, resulting in wind resistance and affecting heat transfer performance.

After the heat exchanger is full of dirt, the thermal resistance will increase, and it will also affect the hydrophilicity of the aluminum foil and increase the wind resistance, which will reduce the heat exchange efficiency of the air conditioner and increase energy consumption, and dust and dirt will easily accelerate the shedding of the hydrophilic material and the aluminum foil. Corrosion, oxidation, shorten the service life of the air conditioner

Moreover, the fins of the evaporator of the existing heat pump water heater main unit are ordinary blue hydrophilic aluminum foil, which cannot decompose and remove various organic substances attached to the surface of the aluminum foil, and does not have the effect of sterilization
