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 th...

Embodiment Construction

[0017] The invention discloses a titanium gold evaporator for a heat pump water heater. Agents and adhesives, in which nano-titanium dioxide is treated with organic and inorganic composite coating on the surface.

[0018] Nano-titanium dioxide (anatase TiO2TiO2) as the main functional component has a size of 7-10nm, and its photocatalytic activity is higher than that of rutile. The present invention utilizes the very stable chemical properties of anatase TiO2TiO2, which has no effect on oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, and sulfur dioxide, and is insoluble in water, fat, dilute acid, inorganic acid, and alkali. in hydrofluoric acid. However, under the action of light, titanium dioxide can undergo continuous redox reactions, and its photochemical activity is quite high especially under ultraviolet irradiation. The decomposition ability of the evaporator is fully guaranteed. The sterilizing component is nano-silver nitrate (AgNO3), and the size is a...

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...
