Abstract
A heat exchanger belongs to the technical field of heat exchange and consists of heat exchanging tubes. The heat exchanger is characterized in that the heat exchanging tubes utilize fin tubes 1. A plurality of fin tubes arranged side by side can be in parallel connection or series connection, or can be connected in parallel or in series in a double-layer form so as to increase heat exchange capacity and efficiency. The fin tubes utilized by the heat exchanger increase heat exchanging areas and increase heat exchange rate. The heat exchanger is particularly adaptable to boilers, and fins can retard rising velocity of hot air generated during combustion and sufficiently transmit heat generated by combustion to water in the tubes, thereby greatly increasing heat exchanging efficiency.
Description
Technical field
The utility model belongs to technical field of heat exchange, relates to the heat exchanger in the boiler.
Background technology
Heat exchanger is widely used in the various aspects of productive life.All be unable to do without heat exchanger from the water heater of life usefulness to the large-sized boiler producing.The height of heat exchanger effectiveness is except the temperature difference between two kinds of heat medium, and the size of the contact-making surface between two kinds of mediums is a key factor.Contact area is big more, and heat exchange is thorough more, but will consider the flow velocity of medium simultaneously, and suitable flow velocity and suitable contact area can reach the highest heat exchanger effectiveness.Phase and duty according to two kinds of mediums select heat exchanger to accomplish suitable flow velocity and suitable contact area, thereby obtain best heat exchanger effectiveness.Heat exchanger is diversified, adopts the heat exchanger of heat exchange tubular type mostly for flowing liquid or gas, and heat-exchange tube generally is smooth pipeline, though do not influence flowing of medium, with the contact area of two kinds of mediums be not very big.
Summary of the invention
The purpose of this utility model is can increase the heat exchanger that provides a kind of extended surface tube to do heat exchange area, and can suppress the higher flow velocity of medium, is particularly useful for doing the heat exchanger of boiler.
To achieve these goals, the utility model has been taked following technical scheme: a kind of heat exchanger, constitute by heat-exchange tube, and it is characterized in that: described heat-exchange tube adopts extended surface tube 1.
In order to increase the capacity of heat exchanger, can many extended surface tubes 1 are placed side by side, with its parallel connection.
In order to obtain and to execute heat medium than consistent temperature, can many extended surface tubes 1 are placed side by side, with its series connection.
In order to obtain higher exchange efficiency, can be with the extended surface tube side by side 1 of top parallel connection or series connection, be set to two-layerly, two interlayers are by in parallel or be connected in series.
In order to obtain higher exchange efficiency, for every row each extended surface tube 1 in parallel, its inlet calibre is less than the outlet bore.
For being the medium of liquid state in the pipe, extended surface tube 1 is provided with certain inclination angle, make the inlet of medium be lower than the outlet of medium, so that the heat exchange between medium is more thorough.
In order to improve corrosion resistance, above-mentioned extended surface tube 1 adopts stainless steel to make.
Compare with existing gas fired-boiler, the utlity model has following advantage: extended surface tube has the outer fin that stretches out of pipe, can increase heat exchange area, improves rate of heat exchange.Be particularly useful in the boiler, the rate of climb of the hot-air that fin can retarded combustion produces is delivered in the water in the pipe heat of burning fully, has greatly improved heat exchanger effectiveness.
Description of drawings
Fig. 1 is the structural representation of the heat exchanger made of extended surface tube in the utility model.
Among the figure: 1, extended surface tube, 2, collecting box pipe, 3, support.
The specific embodiment
Below in conjunction with Fig. 1 the utility model is elaborated: the heat exchanger in the present embodiment is used to use water as the boiler of medium for extended surface tube 1 usefulness collecting box pipe 2 series connection with the two rows parallel connection constitute.
Extended surface tube 1 in the heat exchanger is made by weld circular stainless steel or 20# carbon steel coupon evenly, abreast outside stainless steel or 20# carbon steel pipe.
One with row's extended surface tube 1 is welded on the collecting box pipe 2, as the outlet of water; Be welded on another root collecting box pipe 2, behind the other end expansion stem with each extended surface tube 1 as the inlet of water.Collecting box pipe 2 adopts thicker stainless steel tube.The such extended surface tube of two rows is placed up and down, the collecting box pipe 2 of following outlet as the water collecting box pipe 2 with top inlet as water is connected; And make the two rows extended surface tube certain angle that all tilts by support 3, make the arrival end of water be lower than the port of export of water.
Such heat exchanger, because the pore size that is connected between front and back collecting box pipe 2 and the extended surface tube 1 differs, and gradient of front and back formation, make current along the ramp reverse flow, have two backhauls, strengthened the absorption of heat.
For row's extended surface tube 1 of series connection, without collecting box pipe, the head and the tail of each adjacent tubes of side by side extended surface tube 1 are connected, form coiled pipe.
Alternate manner connects the heat exchanger that extended surface tube 1 constitutes, and all adopts said method to connect.
