Abstract
A bushing type spiral heat exchanger comprises an inner tube and an outer tube. An inner tube flange and a flange cover are fixed at one end of the inner tube, an inner tube seal plate is fixed at the other end of the inner tube, and a cold fluid outlet connecting tube and a hot fluid inlet connecting tube are respectively connected to the inner tube at the side near the inner tube flange. The utility model is characterized in that an inner spiral plate is arranged in the inner tube, an outer spiral plate is sheathed outside the inner tube, the outer tube is sheathed outside the outer spiral plate, and the cold fluid inlet connecting tube and the hot fluid outlet connecting tube are respectively connected to the outer tube at the side near the inner tube flange. As cold fluid and hot fluid synchronously and spirally flow in the inner tube and the outer tube in reverse directions, heat exchange efficiency can be largely improved. As spiral runners are formed by spiral blades, heat control area can be enlarged, and heat supply efficiency can be improved under the condition of small flow resistance increase.
Description
Technical field
The utility model relates to a kind of heat exchanger, specifically relates to a kind of bushing type spiral heat exchanger.
Background technology
In the prior art, the double pipe heat exchanger that comprises tube-in-tube condenser, be field common devices such as refrigeration, chemical industry, thermal power, its effect is to pay working substance steam by cold fluid to carry out carrying out between condensation or the cold fluid and hot fluid heat exchange, usually form by interior pipe and sleeve pipe, outer with pipe in the pipe of interior pipe is respectively the fluid of variety classes or temperature, but existing double pipe heat exchanger heat exchange efficiency is constant, and the flow of heat exchanging fluid is also less.
The utility model content
The purpose of this utility model is to provide a kind of heat exchange efficiency height, bushing type spiral heat exchanger that the heat exchange flow is big.
The technical scheme that adopts is:
A kind of bushing type spiral heat exchanger, an end that comprises interior pipe, outer tube, interior pipe is fixed with interior pipe flange and blind flange, pipe shrouding in the other end of interior pipe is fixed with, interior pipe is connected with cold fluid discharge connection and hot fluid inlet connection respectively near interior pipe flange one side, it is characterized in that being equiped with the inside spin plate in the described interior pipe, the outer cover of interior pipe is equipped with the external spiral plate, outer tube is nested with the outside of spiral plate outside, and outer tube is connected with cold fluid inlet connection and hot fluid discharge connection respectively near interior pipe flange one side.
The utility model since cold and hot fluid in interior pipe and the reverse helical flow of outer tube inter-sync, thereby can improve heat exchange efficiency greatly, simultaneously because flight forms helical flow path, it is long-pending to increase the control hot side, can increase under the less situation in flow resistance again, improve and pay the thermal efficiency.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
