Abstract

The invention relates to a tank heat exchanger for a heat pump system. The tank heat exchanger for the heat pump system comprises an outer cylinder, a gas-liquid separator, a heat exchange pipe and a baffle plate, wherein an upper cover plate and a lower cover plate are respectively arranged at the top and the bottom of the outer cylinder; a refrigerant inlet is formed in the bottom of the outer cylinder; a refrigerant outlet is formed in the upper cover plate; the gas-liquid separator includes an inner cylinder; an upper sealing plate and a lower sealing plate are respectively arranged at the top and the bottom of the inner cylinder; the upper sealing plate is provided with an intake pipe and an exhaust pipe; the heat exchange pipe is arranged between the outer cylinder and the inner cylinder, and is spirally coiled out of the inner cylinder; a water outlet and a water inlet are respectively formed in the upper end and the lower end of the heat exchange pipe; and the baffle plate is arranged below the upper cover plate and above the heat exchange pipe. The tank heat exchanger has the advantages of high heat exchange efficiency, low cost, convenience to maintain and clean and excellent freeze preventing function.

Description

technical field [0001] The invention relates to a tank heat exchanger, in particular to a tank heat exchanger used in a heat pump system. Background technique [0002] Air source / water source heat pump is an ideal way to replace coal-fired boiler heating in the north because of its energy saving, environmental protection and no pollution emission. At present, the load side heat exchangers commonly used in air source / water source heat pumps are plate heat exchangers, dry heat exchangers and casing heat exchangers. These types of heat exchangers have low heat transfer performance. During heating, due to the relatively high temperature of hot water, the water side is prone to scaling and difficult to clean, resulting in severe performance attenuation, which affects the energy-saving effect and application range of air source / water source heat pumps. The plate heat exchanger is not resistant to freezing. When heating in the north, it often becomes the source of freezing and cr...
