Abstract
The invention relates to a cold water heat exchanger with shell inner evaporation, a copper pipe waterway and a single spacer plate. The cold water heat exchanger comprises shells, a front end cover,a front clapboard, the spacer plate, a rear end cover, a rear clapboard and a copper pipe. The shells are cylindrical cast iron shells; multiple sections of shells are serially connected end to end and sealed; each section of shell is provided with a refrigerating fluid inlet, a refrigerating fluid outlet, an exhaust port and an oil discharge port; a baffle plate is welded to a position, corresponding to each refrigerating fluid outlet, in each shell; a bottom shell of the front end cover is in a curve eight shape; two ends of the spacer plate are welded to end parts of the two sections of shells; a water cavity is formed between the rear end cover and the rear clapboard; and the rear clapboard is provided with a ring slot. According to the cold water heat exchanger provided by the invention, the shells are serially connected, so that the space occupation can be reduced; and with the baffle plates in the shells, refrigerating fluids cannot be directly discharged from the refrigeratingoutlets when starting.
Description
technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a cold water heat exchanger with a single partition plate for evaporating copper pipe water channels in a casing. Background technique [0002] Both the evaporator and condenser in the refrigeration system are a specific form of heat exchanger. In the central air-conditioning industry, the evaporator has a variety of forms, including shell-and-tube, plate and other forms. The shell-and-tube type is generally suitable for air-cooled units that prepare cold water. In most regions of the country, different seasonal differences lead to different cooling capacity. For example, during the peak cooling time in summer, full power is required for cooling, but in winter and other seasons when cooling demand is low, full power is not required. At present, there is also frequency conversion technology that can solve the problem of cooling capacity changes within a certain r...
