Abstract
The utility model discloses a finned pipe heat exchanger, comprising an external pipe, a fixing pipe and a finned pipe. The finned pipe is spirally coiled on the fixing pipe in the pipe cavity of theexternal pipe. The finned pipe spirally coiled on the fixing pipe is arranged inside the external pipe, therefore, the actual length of the finned pipe is much more than the boundary length of the heat exchanger due to the coiled way, thereby having the high heat exchanging efficiency and solving the contradiction in the heat exchanger used by a refrigerating device that the channel needs to be very long, but the boundary dimension is strictly limited.
Description
Technical field
The present invention relates to a kind of fin tube type heat exchanger, be specifically related to a kind of fin tube type heat exchanger that is mainly used in refrigeration plant.
Background technology
Existing fin tube type heat exchanger is generally shell and tube, and finned tube bends to zigzag earlier, and second order buckling becomes overlapped again, the fin tube type heat exchanger of this structure is because twice of curved fins pipe, complicate fabrication process, and institute takes up space greatlyyer, and heat exchange efficiency is not high yet.Patent CN1258065C discloses a kind of coil form fin tube type heat exchanger, finned tube overcoat one is managed coiled coil form together, finish the transmission of heat by the heat transmission between cold-producing medium and the air, but the finned tube of the fin tube type heat exchanger of this structure and employing support be finned tube and outer tube thereof fixedly, complex process, and difficulty of processing is big, simultaneously owing to adopt air as heat transfer medium, blower fan and drive motors need be set, limit the miniaturization of heat exchanger, the cost height.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of heat exchange efficiency height, in light weight, fin tube type heat exchanger that volume is little.
The present invention is achieved in that
A kind of fin tube type heat exchanger comprises outer tube, stationary pipes, finned tube, and described finned tube is coiled on the stationary pipes at outer tube tube chamber inside spin shape.
Also can do further perfect by the following technical programs:
Described finned tube helical form is coiled in and becomes coil form on the stationary pipes, and the stationary pipes two ends are connected and fixed by welding and finned tube.
Described outer tube one end is provided with ingress pipe, and the other end is provided with delivery line, and the outer tube two ends are provided with diaphragm seal.
Described stationary pipes both ends open, stationary pipes tube chamber and outer tube lumen therethrough.
Be provided with groove array around the described outer tube outer wall.
The present invention is arranged in the outer tube by the finned tube that helical form is coiled on the stationary pipes, this coiling mode makes that the physical length of finned tube is long more a lot of than heat exchanger contour length, and heat exchange efficiency is high and efficiently solve refrigeration plant with requiring passage very long but appearance and size is had the strict contradiction that limits again in the heat exchanger.
Description of drawings
Fig. 1 is the cutaway view of fin tube type heat exchanger most preferred embodiment;
Fig. 2 is the outside drawing of fin tube type heat exchanger most preferred embodiment;
Fig. 3 is that the A-A of Fig. 2 is to enlarged diagram;
Fig. 4 is that the B-B of Fig. 2 is to enlarged diagram.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
As shown in Figure 1, 2, a kind of fin tube type heat exchanger comprises outer tube 1, stationary pipes 3, finned tube 2, and described finned tube 2 is coiled on the stationary pipes 3 at outer tube 1 tube chamber inside spin shape.
Described finned tube 2 helical forms are coiled on the stationary pipes 3 and become coil form, and stationary pipes 3 two ends are connected and fixed by welding and finned tube 2.
Described outer tube 1 one ends are provided with ingress pipe 5, and the other end is provided with delivery line 7, and the outer tube two ends are provided with diaphragm seal 4.
Described stationary pipes 3 both ends opens, stationary pipes 3 tube chambers and outer tube 1 lumen therethrough.
Be provided with groove array 6 around described outer tube 1 outer wall.
Referring to Fig. 1, during fin tube type heat exchanger work, first medium flows into from ingress pipe 5, enters outer tube 1 tube chamber, and a part of first medium enters stationary pipes 3 tube chambers, flows out from delivery line 7 then; Simultaneously, second medium enters from an end of finned tube 2, and along finned tube 2 inflow heat exchangers and outflow, first medium is opposite with the mobile aspect of second medium, finishes the heat exchange between the two media in heat exchanger.
Claims (5)
