Abstract

The utility model relates to the improvement technology of heat exchangers, in particular to a novel double-layer cooling high-efficiency tubular heat exchanger which mainly consists of three parts, namely, a shell, end cover assemblies arranged at two ends of the shell, and a core group installed at the inner part of the shell, wherein the shell is provided with a cooled medium inlet and a cooled medium outlet. The special points are as follows: the shell is designed as a double-layer structure, a cooling chamber is formed between interlayers, and the shell is provided with a cooling medium inlet and a cooling medium outlet which are communicated with the cooling chamber. The heat exchanger breaks through traditional concepts, solves the problem that the improvement of the heat exchange efficiency of the heat exchanger is limited as only a core group of the heat exchanger is improved, has the breakthrough improvement on the heat exchange efficiency, and can be widely applied to the industries such as ships, metallurgy, chemistry and the like.

Description

The efficient shell-and-tube heat exchanger of double-deck cooling

(1) technical field: the utility model relates to the improvement technology of heat exchanger, the efficient shell-and-tube heat exchanger of especially a kind of double-deck cooling.

(2) background technology: at present, in the heat exchanger industry, shell-and-tube heat exchanger mainly is made up of housing, the end-cap assembly that is contained in the housing two ends, core group three parts that are contained in enclosure interior, and housing is provided with the medium import and export that is cooled.Shell-and-tube heat exchanger is that industrial process heat delivery applications is the most a kind of, though shell-and-tube heat exchanger wouldn't be comparable with plate type heat exchanger, plate-fin heat exchanger at aspects such as structural compactness, heat transfer properties, but the scope of shell-and-tube heat exchanger Applicable temperature and pressure is wide, make simple relatively, clean and maintenance is convenient, and the big heat exchange engineering of energy treating capacity, stable and reliable for performance.For a long time, people are accumulating many experiences aspect its design and the processing and manufacturing, constantly the cooling tube element in the shell-and-tube heat exchanger core group is improved the innovation research and development, tens kinds of tube elements such as various screwed pipes, corrugated tube, shape tube, spiral flat tube, finned tube, internally finned tube have successively been developed, make heat exchange efficiency obtain certain raising, but up to now, all improve to research and develop and all just carry out at the elements such as cooling tube in the core group, thereby make the raising of the heat exchange efficiency of shell-and-tube heat exchanger be subjected to restriction.

(3) summary of the invention: the purpose of this utility model will solve existing research and development scheme exactly and only limit to the core group is improved, and makes the heat exchange efficiency of shell-and-tube heat exchanger improve little problem, provides a kind of breakthrough bilayer to cool off efficient shell-and-tube heat exchanger.

The utility model is to change the traditional design thinking, housing parts to shell-and-tube heat exchanger improves, concrete scheme is: the efficient shell-and-tube heat exchanger of double-deck cooling, mainly form by housing, the end-cap assembly that is contained in the housing two ends, core group three parts that are contained in enclosure interior, housing is provided with the medium import and export that is cooled, it is characterized in that: described housing is designed to double-decker, forms cooling chamber between the interlayer, and is provided with the cooling medium import and export that is communicated with cooling chamber on housing.

For improving the cooling effect of housing cooling chamber, in the interlayer cooling chamber of described housing, some toroidal membranes are installed in the utility model, have some through holes on the toroidal membrane, the through hole interlaced arrangement on adjacent two dividing plates.

For improving the cooling effect of housing cooling chamber, design has the structure of streaming in the interlayer cooling chamber of housing described in the utility model.

The above-mentioned structure of streaming can have multiple scheme in the utility model, the utility model proposes following three kinds of typical scenarios:

Scheme one: the formula structure of streaming in the interlayer cooling chamber of housing described in the utility model is spiral runner.

Scheme two: the formula structure of streaming in the interlayer cooling chamber of housing described in the utility model is the serpentine runner.

Scheme three: the formula structure of streaming in the interlayer cooling chamber of housing described in the utility model is " U " shape runner.

Thereby the utility model has been set up cooling chamber and has been formed inside and outside double-deck cooling with the core group in housing, improved heat exchange efficiency of the present utility model greatly, compares with existing shell-and-tube heat exchanger, and under the same conditions, heat exchange efficiency can improve 15%-30%.The utility model is simple in structure, is easy to make, and can be widely used in industries such as boats and ships, metallurgy, chemical industry.
