Abstract

The utility model discloses a heat exchanger, including outer tube and inner tube, outside of tubes including outer pipe box is established, outer tube one end is the second fluid import, and the other end is second fluid and exports, inner tube one end is the first fluid import, and the other end is first fluid and exports, the outer tube is the multi -screw pipe. Set the outer tube to the multi -screw pipe, can increase heat transfer area effectively, improve heat exchange efficiency, can effectively reduce unit area heat transfer metal consumption simultaneously, reduce manufacturing cost.

Description

A kind of heat exchanger
Technical field
The utility model relates to a kind of heat exchanger.
Background technology
Heat exchanger has excellent heat exchange property, is the common apparatus of the field extensive uses such as refrigeration air-conditioner, chemical industry, power.The double pipe heat exchanger adopted in the market, structure is simple, easy to process, but unit are heat exchange metal consumption is large, manufacturing cost is higher, the inner tubal wall of some double pipe heat exchangers makes and adopts annular knurl or water fin design, although unit are heat exchange metal consumption decreases, manufacturing cost is still very large.Therefore, effectively reduce unit are metal consumption and become making double pipe heat exchanger key technology.Meanwhile, heat exchanger is the critical piece of heat-exchange system, and efficiency of heat exchanger has influence on the energy efficiency of heat-exchange system, in order to respond the call that national energy-saving reduces discharging, need the manufacturing cost reducing heat exchanger further, improve the heat exchange efficiency of heat exchanger, improve heat transfer effect.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of unit are heat exchange metal consumption is low, the heat exchanger of good effect of heat exchange.
To achieve these goals, a kind of heat exchanger designed by the utility model, comprise outer tube and interior pipe, described outer tube sleeve is located at outside interior pipe, described outer tube one end is second fluid import, and the other end is second fluid outlet, and described interior pipe one end is first fluid import, the other end is first fluid outlet, and described outer tube is multi-start helical tubes.Multi-start helical tubes can increase heat exchange area effectively, improving heat exchanging efficiency.
Described interior Guan Yiwei multi-start helical tubes.
Described interior pipe comprises main paragraph and is positioned at the reducing section at main paragraph two ends, and described main paragraph is multi-head spiral pipeline section and corresponding with outer tube.
Described outer tube two ends are connected to coupled logical upper shield, the periphery that described upper shield one end is set in outer tube seals with the outer phase of outer tube, the periphery that the other end is set in reducing section seals mutually with reducing section, and described upper shield periphery is provided with coupled logical adapter.
Described interior pipe and outer coaxial tube are arranged.
Described interior pipe and outer tube are that straight tube-like is arranged.
Described interior pipe and outer tube are coil-like setting.
Described first fluid import and second fluid import are positioned at outer tube wherein one end, and described first fluid outlet exports with second fluid and is positioned at the outer tube other end.
Described first fluid import and second fluid export and are positioned at outer tube wherein one end, and described first fluid outlet is positioned at the outer tube other end with second fluid import.
A kind of heat exchanger that the utility model obtains, its technique effect is: 1, outer tube is arranged to multi-start helical tubes, effectively can increase heat exchange area, improves heat exchange efficiency, effectively can reduce unit are heat exchange metal consumption simultaneously, reduces manufacturing cost; 2, interior pipe is also arranged to multi-start helical tubes, can improve heat exchange efficiency further, strengthens heat transfer effect, reduces manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is explosive view of the present utility model.
Fig. 3 is the straight tube-like heat exchanger contour structures schematic diagram that the utility model provides.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, 2, a kind of heat exchanger that the utility model provides, comprise outer tube 1 and interior pipe 2, outer tube sleeve is located at outside interior pipe, outer tube 1 one end is second fluid import, and the other end is second fluid outlet, and interior pipe 2 one end is first fluid import, the other end is first fluid outlet, and outer tube and interior pipe are multi-start helical tubes.Multi-start helical tubes can increase heat exchange area effectively, reduces unit are heat exchange metal consumption, improving heat exchanging efficiency.
Interior pipe 2 comprises main paragraph 21 and is positioned at the reducing section 22 at main paragraph two ends, and main paragraph is multi-head spiral pipeline section and corresponding with outer tube.
Outer tube 1 two ends are connected to coupled logical upper shield 3, upper shield 3 one end to be set on outer tube periphery and to seal with the outer phase of outer tube, the periphery that the other end is set in reducing section 22 seals mutually with reducing section, and upper shield 3 periphery is provided with coupled logical adapter 4.
In the present embodiment, interior pipe 2 is coaxially arranged with outer tube 1.
In the present embodiment, interior pipe 2 and outer tube 1, in coil-like setting, also can be arranged to straight tube-like as shown in Figure 3, or even other shapes, such as vortex shape, runway shape, snakelike shape etc.
First fluid import and second fluid import are positioned at outer tube 1 wherein one end, and first fluid outlet exports with second fluid and is positioned at the outer tube other end.Namely the flow direction of first fluid is identical with the flow direction of second fluid, can be used as evaporimeter and uses.
First fluid import and second fluid export and are positioned at outer tube wherein one end, and first fluid outlet is positioned at the outer tube other end with second fluid import.Namely the flow direction of first fluid is contrary with the flow direction of second fluid, can be used as condenser and uses.
