Abstract

The utility model discloses a compact heat exchanger, which comprises a shell and an inner coil arranged in the shell. The inner coil and the shell form a refrigerant cavity, the two ends of the refrigerant cavity are respectively provided with an opening, and the two ends of the inner coil extend out of the shell. The refrigerant cavity between the inner coil and the shell is used as a refrigerant channel, and the inner coil is used as a water channel, thereby effectively improving the heat exchange efficiency of water and refrigerant. Moreover, the utility model can achieve good heat exchange effect only with a small structure.

Description

Compact heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, particularly a kind of heat exchanger of high-efficiency compact.

Background technology

Heat exchanger be a kind of can be with the equipment of the part heat transferred cold fluid of hot fluid.Heat exchanger is a chemical industry, oil, and power, the common apparatus of food and other many industrial departments occupies critical role aborning. and heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc. in Chemical Manufacture, uses more extensive.The heat exchanger kind is a lot, but can divide three major types promptly basically according to the principle and the mode of cold and hot fluid exchange heat: dividing wall type, hybrid and heat accumulating type.

Present heat exchanger is exactly that volume is bigger all a general shortcoming, and the occasion comparatively narrow in some spaces can not be used, and for the less heat exchanger of some volumes, because the restriction of its internal structure, discharge is less again, and heat exchange efficiency is not high.

The utility model content

At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of simple in structure, compact, the heat exchanger that heat exchange efficiency is high.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of compact heat exchanger, it comprises a shell and an inner coil pipe, and described inner coil pipe is positioned at described shell, forms the cold-producing medium cavity between described inner coil pipe and the described shell, described cold-producing medium cavity two ends are provided with opening, and described shell is stretched out at the two ends of described inner coil pipe.

Preferably, described shell comprises an inner core and a urceolus, and described inner core is positioned at described urceolus, and described inner coil pipe is coiled on the described inner core, and the upper/lower terminal of described shell is respectively equipped with upper top cover and lower bottom cover.

Preferably, described inner coil pipe is that screwed pipe or inside are the pipeline of fin for threaded exterior.

Technique scheme has following beneficial effect: this compact heat exchanger is with the passage of the cold-producing medium cavity between inner coil pipe and the shell as flow of refrigerant, and the passage that inner coil pipe is flowed as water, so just can effectively increase the heat exchanger effectiveness between water and the cold-producing medium, adopt and just can obtain good heat exchange effect than minor structure.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Fig. 1 is the front view of the utility model embodiment.

Fig. 2 is the vertical view of the utility model embodiment.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.

As shown in Figure 1, 2, this compact heat exchanger comprises a shell 2 and an inner coil pipe 1, and it is the pipeline of fin for threaded exterior that inner coil pipe 1 can adopt screwed pipe or inside.Inner coil pipe 1 is positioned at shell 2, forms the cold-producing medium cavity between inner coil pipe 1 and the shell 2, and the upper end of cold-producing medium cavity is provided with opening 21, and the lower end is provided with opening 22, and shell 2 is all stretched out in upper end 11, the lower end 12 of inner coil pipe 1.Shell 2 comprises an inner core 4 and a urceolus 3, and inner core 4 is positioned at urceolus 3, and inner coil pipe 1 is coiled on the outer wall of inner core 4, and the upper end of shell 2 is provided with upper top cover 5, the lower end is provided with lower bottom cover 6.

This compact heat exchanger is the passage of the cold-producing medium cavity between inner coil pipe 1 and the shell 2 as flow of refrigerant, and the passage that inner coil pipe 1 is flowed as water.Cold-producing medium goes out under enterprising when making condenser, goes out on advancing under water; When making evaporimeter, on advancing under the cold-producing medium, waterbornely go out under advancing.

Adopt the Teat pump boiler of this structure can effectively increase heat exchanger effectiveness between water and the cold-producing medium, adopt and just can obtain good heat exchange effect than minor structure, this Teat pump boiler also has simple in structure, lack compact the occupation of land, water stream channel is big, and water temperature changes greatly, pieces together advantages such as flexible.

More than a kind of compact heat exchanger that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
