Caisson type seawater source heat pump heat exchanger

Abstract

The invention discloses a caisson type seawater source heat pump heat exchanger. The heat exchanger comprises a heat exchange tube, a super-hydrophobic coating, a heat transfer medium, a liquid inletheader, a liquid outlet header and a partition board part. The surface of the outer side of the heat exchange tube is coated with the super-hydrophobic coating, the heat exchange medium is arranged inthe heat exchange tube, and an external contact fluid is seawater; the two ends of the heat exchange tube are connected with the liquid inlet header and the liquid outlet header respectively, and partition boards are arranged in the liquid inlet header and the liquid outlet header respectively. According to the heat exchanger, a metal tube with good heat conduction performance serves as the manufacturing material, and the defects that original titanium and nickel alloy is high in manufacturing cost and poor in economical efficiency, and the heat transfer performance of polyethylene tubes is poor are overcome. The super-hydrophobic coating structure on the surface of the novel heat exchanger not only provides anti-icing performance in winter in cold regions, but also has the anti-corrosioneffect. The novel heat exchanger is composed of a tube bundle, the liquid inlet header and the liquid outlet header, only the form of the heat exchanger and the outer surface layer of the tube are processed, and a manufacturing method is simple and convenient to apply in engineering practice.

Description

technical field [0001] The invention relates to the field of seawater source heat pumps, in particular to a caisson type heat exchanger which is suitable for seawater source heat pump systems and can slow down freezing. Background technique [0002] The seawater source heat pump system is a low-level thermal energy formed by using seawater to absorb solar energy and geothermal energy. According to the operation principle of the heat pump, it realizes the conversion of low-level thermal energy to high-level thermal energy through less high-level electrical energy input, and provides heat for buildings in winter. A system. Seawater source heat pump technology for heating in winter can replace traditional heating methods such as coal burning. It is a heating method using clean energy, which can greatly reduce the emission of pollutants. Because the seawater temperature is often higher than the air temperature, the system performance of the seawater source heat pump is better th...
