Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] refer to Figure 1-Figure 6 , a shell-and-tube dry evaporator of the present invention includes a distributor 2, a refrigerant outlet pipe 3, an end cover 4, an arcuate baffle 6, a heat exchange tube 7, an outlet pipe 8, an inlet pipe 9, a bracket 10 and a cylinder body 11 etc.
[0029] The present invention is a dual-system shell-and-tube heat exchanger, which has two sets of independent inlets and outlets for refrigerant working fluid, and shares the water side for heat exchange.
[0030] One end of the cylinder body 11 is closed, and the other end is open. The cylinder body 11 is provided with heat exchange tubes 7 and arcuate baffles 6 , and the heat exchange tubes 7 are arranged in a square arrangement. The heat exchange tubes 7 pass through the arcuate baffles 6 , and a plurality of arcuate baffles 6 are arranged in a staggered manner to enhance heat exc...

The invention discloses a shell-and-tube type dry evaporator, comprising a distributor, an arcuate baffle, a heat exchange tube and a cylinder; wherein, one end of the cylinder is closed, the other end is open, and the cylinder is provided with a heat exchange tube and a cylinder. The arcuate baffle, the heat exchange tube passes through the arcuate baffle, and the open end of the cylinder is provided with a multi-stage distributor; the top and bottom of the cylinder are respectively provided with openings, and the water-side inlet pipe is installed in the opening at the bottom. The water-side outlet pipe is installed in the opening of the end cover; the distribution channel is processed in the lower part of the end cover, and the distribution channel is connected with the inlet of the heat exchange tube; The cavity is provided with an outlet. The dispenser used in the invention has a simple structure, can be processed by processing methods such as laser cutting and wire cutting, has low manufacturing cost, and is convenient for large-scale popularization and use. The invention reduces the consumption of heat exchange tubes by more than 30% through the design and use of the inlet distributor and the arcuate baffle.
Description
technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to a shell-and-tube dry evaporator. Background technique [0002] Shell and tube heat exchanger is the most widely used form of heat exchanger, which has the advantages of simple structure, strong adaptability and easy maintenance. Its main components include cylinder, end cover, tube sheet, baffle plate, heat exchange tube, etc. Shell and tube heat exchangers are widely used in air conditioning and refrigeration equipment as evaporators / condensers. Some existing shell-and-tube heat exchangers have the following disadvantages when used as evaporators / condensers: the flow rate of the working medium in each heat exchange tube is not uniform, resulting in different heat transfer conditions and low heat transfer efficiency; The margin results in a waste of heat exchange area; the refrigerant is prone to leakage; the processing method is complicated, and the processing equipmen...
