The efficient coil shell heat exchanger is a compact, high performance heat exchanger. Compared with the traditional heat exchangers, the casing shell heat exchanger has lower heat exchanging performance and the volume is too large; while the plate heat exchanger has small water passages, is easy to block, and is difficult to repair after failure. High-efficiency coil-shell heat exchanger series heat exchangers have high heat exchanging efficiency, small volume, large cross section of water passage, effective reduction of fouling, and shell-and-tube heat exchanger which can be used as condenser, evaporator and fluid heater or cooler use.
According to the heat exchange medium of the shell-and-tube heat exchanger, it can also exhibit superior performance in various heat exchange processes such as water-water, water-R22 (or other refrigerant), water-oil, water-gas, and so on. The heat transfer core of the shell-and-tube heat exchanger is produced by Longpai Company using advanced technology and production technology. The materials of high-efficiency tubes can be selected from the ordinary copper series and nickel-copper anticorrosion series according to the user's applicable conditions. At present, the shell-and-tube heat exchanger products have been widely used in the market in various industrial fields such as central air conditioning water cooling units, heat pump hot water units, and industrial chillers. The rapid development of domestic water source heat pumps in recent years has changed the water heat pump market that was originally controlled by foreign shell-and-tube heat exchanger companies. Domestic Haier, Midea, and Gree air-conditioning giants have begun to enter this field. The future use of high-efficiency coil-shell heat exchangers will be a very large market.
High-efficiency coil-shell heat exchanger is an important component in the ground/water source heat pump system. Its function is to exchange heat between water and refrigerant, and to replace the aluminum fin heat exchanger that exchanges heat with the outside in the air source heat pump system. The coil tube shell heat exchanger structure has its unique advantages:
1. Shell-and-tube heat exchangers are less expensive than stainless steel plate heat exchangers. Therefore, in the ground source/water source heat pump unit, the brazed stainless steel plate heat exchanger cannot compete with the high efficiency coil heat exchanger.
2. The inner tube of shell-and-tube heat exchanger is made of stainless steel with thermal conductivity of 401W/m*K and is superior to stainless steel with thermal conductivity of 50W/m*K.
3. Good oil return characteristics of shell and tube heat exchangers. The compact spiral structure of the internal coils tightly fits with the housing, so the lubricant can be safely returned to the compressor even under low flow conditions. The shell-and-tube heat exchanger does not have to worry about the various hazards such as reduced heat exchange area, blocked flow channels, unstable operation, and destroyed presses due to evaporator lag.
4. The shell-and-tube heat exchanger is safe to use. The special structure and high elongation of the inner copper tube and the thicker wall thickness and high pressure resistance make it more resistant to water freezing and pressure than the stainless steel plate heat exchanger.
5, shell and tube heat exchanger water quality requirements are low, the water side of the flow channel has a larger cross-sectional size, can allow the water to entrain larger diameter fibers, sediment and other impurities through, causing a small possibility of clogging. Similarly, the possibility of blockage due to fouling of the shell and tube heat exchanger is very small. Therefore, the adaptability to the water quality is stronger than the plate heat exchanger.
