Abstract
The invention relates to an evaporator for refrigeration equipment, belonging to the technical field of heat exchangers in refrigeration equipment. The evaporator for refrigeration equipment comprises a heat transfer plate and a heat transfer tube, characterized in that the heat transfer tube adopts a metal special tube with a D-shaped cross section formed by extruding a metal round tube which is 6-10mm in diameter and 0.5-1.2mm in wall thickness; and the heat transfer tube is composed of a flat tube wall and a cambered tube wall, the flat tube wall and the cambered tube wall are chamfered at the connection, and the width L of the flat tube wall to the height H of the cambered tube wall is 0.8-1.5. According to the invention, the contact area between the heat transfer tube and the heat transfer plate is effectively increased, thermal resistance is greatly reduced, and heat transfer efficiency is improved.
Description
Technical field
The invention belongs to the heat exchanger technical field in the refrigeration plant, be specifically related to a kind of refrigeration plant and use evaporimeter
Background technology
are along with the raising of China's rapid economy development and living standards of the people; Market sharply increases the demand of aquatic products and meat; Strong promotion the development of the freezing industry of meat product, the refrigeration of aquatic products and meat and fresh-keeping link are become very important.Almost each family has all used refrigeration plants such as refrigerator, air-conditioning, and the electric energy that these refrigeration plants expend is very surprising, and China is the developing country of an energy scarcity, reduces power consumption energetically, is air-conditioning and refrigerator industry institute urgent problem.
evaporimeter is one of device necessary in the refrigeration plants such as refrigerator, air-conditioning; Its effect is to make low pressure, low-temperature refrigerant liquid in boiling process, absorb the heat of the medium that is cooled (air, water, salt solution or other refrigerating mediums); And in the space at its place, put cold air, thereby reach the purpose of refrigeration.At present, the employed evaporimeter of refrigerator is installed in the foaming layer, transmits cold across the refrigeration courage to refrigerating chamber.The structure of this evaporimeter is disclosed by Fig. 1; Mainly comprise heat transfer plate 1, heat-transfer pipe 2, described heat-transfer pipe 2 is a metal circular tube, and its cross sectional shape is circular; Heat-transfer pipe 2 usefulness melt viscosities are to described heat transfer plate 1, and the bang path of cold is: heat-transfer pipe → heat transfer glue → heat transfer plate.In said structure, because the contact area of metal circular tube and heat transfer plate is little, heat exchanger effectiveness is extremely low, and temperature underspeeds slowly, and is not energy-conservation.
Problems such as the contact area to metal circular tube and heat transfer plate in the existing evaporimeter is little, heat exchanger effectiveness is extremely low, not energy-conservation; Be necessary existing evaporation structure is improved; For this reason; The applicant has carried out good try, has found the way that solves the problems of the technologies described above, and the technical scheme that will introduce below produces under this background
Summary of the invention
the objective of the invention is to provide a kind of contact area, heat exchanger effectiveness height, energy-conservation refrigeration plant that can effectively increase between heat-transfer pipe and the heat transfer plate to use evaporimeter.
the objective of the invention is to reach like this; A kind of refrigeration plant is used evaporimeter; Comprise heat transfer plate, heat-transfer pipe; Be characterized in: it is that 6-10mm, wall thickness are that the metal circular tube of 0.5-1.2mm is squeezed into the metal shaped tube that shape of cross section is " D " shape that described heat-transfer pipe adopts diameter; This heat-transfer pipe is made up of plane tube wall and cambered surface tube wall, and described plane tube wall and described cambered surface tube wall are provided with chamfering in the junction, and the ratio of the height H of the width L of plane tube wall and cambered surface tube wall is between 0.8～1.5.
in a concrete embodiment of the present invention, described heat-transfer pipe be inside and outside copper-plated Bandaid pipe or aluminum pipe.
the present invention is owing to be designed to the metal shaped tube of shape of cross section for " D " shape with the circular heat-transfer pipe in the prior art; Through combining of the plane tube wall on the heat-transfer pipe and heat transfer plate, can effectively increase the contact area between heat-transfer pipe and the heat transfer plate, greatly reduce thermal resistance; Improved heat transfer efficiency; Compared with prior art, freeze-off time is to adopt about 1/3～1/4 of typical circular heat-transfer pipe under the equal conditions, but saves energy is more than 25%.
