Abstract
The invention discloses a screw type heat exchanger which comprises a cylindrical shell and an inner core. Two hollow ends are arranged at the two ends of the cylindrical shell. A heat medium inlet is formed in one of the hollow ends, and a heat medium outlet is formed in the other end. A cold medium inlet and a cold medium outlet are formed in the cylindrical shell. The inner core is installed in the cylindrical shell. The inner core is composed of two end plates and a plurality of screw type flat hollow pipes arranged between the two end plates. The screw type flat hollow pipes penetrate the two end plates and are connected with the end plates through sealing rings in a sealed manner. The cylindrical shell, the two end plates of the inner core and the two hollow ends are connected in a sealed manner. According to the screw type heat exchanger, the screw type flat hollow pipes are designed, a heat exchange runner of the screw type heat exchanger is long, due to the fact that the screw type heat exchanger is flat, the contact area of the screw type heat exchanger is large, and the heat exchange efficiency is high.
Description
Technical field
The present invention relates to chemical industry for the heat exchanger apparatus that heat exchanges, be specifically related to a kind of votator.
Background technology
Heat exchanger apparatus application in chemical industry is more universal, mainly to carrying out heat exchange between different medium.Traditional heat exchanger mostly is shell-and-tube heat exchanger, and its shortcoming is that circulation medium needs higher degree of purity, otherwise easily causes blocking.Chinese patent grant number CN201740434U discloses a kind of spiral-plate heat exchanger, by curl that metallic plate is intervally arranged from inside to outside, but owing to its center is provided with straight plate, easily make fluid media (medium) form eddy current and cause resistance, and on the one hand life-time service can make metallic plate spacing distance inconsistent, and then affect heat exchange efficiency, on the other hand can make corrosion of metal sheet, cause dielectric leakage, affect equipment using effect and service life.
Summary of the invention
The present invention is directed to deficiency of the prior art, it is provided that a kind of votator.
The present invention is to be realized by following technical scheme: a kind of votator, including cylindrical shell, inner core, cylindrical shell two ends are provided with two hollow terminations, one of them hollow termination is provided with Heating medium, another termination is provided with heating agent outlet, cylindrical shell is provided with coolant import, refrigerant exit, inner core is installed in cylindrical shell, described inner core is made up of two end plates and several spiral flat-shaped hollow pipes being placed between two end plates, spiral flat-shaped hollow pipe through two end plates and and end plate use sealing ring be tightly connected, cylindrical shell, it is tightly connected between two end plates and two hollow terminations of inner core.
Preferred as such scheme, the cross section of described spiral flat-shaped hollow pipe is oval.
Wherein, oval major axis is more than four with the ratio of short axle.
It is an advantage of the current invention that: the present invention uses spiral flat-shaped hollow pipe design, and its heat exchange runner is long, owing to being flat-shaped, its contact area is big, and heat exchange efficiency is high.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
As shown in Figure 1 to Figure 3, a kind of votator, including cylindrical shell, inner core, cylindrical shell two ends are provided with two hollow terminations, one of them hollow termination is provided with Heating medium, another termination is provided with heating agent outlet, cylindrical shell is provided with coolant import, refrigerant exit, inner core is installed in cylindrical shell, described inner core is made up of two end plates and several spiral flat-shaped hollow pipes being placed between two end plates, spiral flat-shaped hollow pipe through two end plates and and end plate use sealing ring be tightly connected, the cross section of spiral flat-shaped hollow pipe is oval, wherein, oval major axis is more than four with the ratio of short axle, cylindrical shell, it is tightly connected between two end plates and two hollow terminations of inner core.
Above-described is only the preferred implementation of a kind of spiral-plate heat exchanger of the present invention; it should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also make some deformation and improvement, these broadly fall into protection scope of the present invention.
