Problems solved by technology

[0002] The heat exchange main parts of the traditional heat exchanger are stationary, relying on the heat exchange medium to flow in the heat exchanger, and the two mediums perform heat exchange on the wall of the heat exchanger. In order to improve the heat exchange effect, various methods are adopted. The shape of the heat exchange surface and the increase of the flow rate of the medium can increase the Re number to increase the heat transfer coefficient; while increasing the flow rate of the medium will increase the fluid resistance. Since the resistance and the flow rate are quadratic, it is impossible to design the heat exchanger Infinitely increase the flow rate, so the current heat exchanger desi...

Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0019] according to figure 1 As shown, the technical solution of the present invention is to provide a heat exchanger that rotates the heat exchange surface to enhance heat exchange, including a shell 1, an inner cylinder 2, a motor 7, a rotating pipe a3, a rotating pipe b4, a heat exchange medium a, heat exchange medium b, bearing a5 and bearing b6; fluid inlets and outlets are provided at the upper and lower ends of the housing 1, and the fluid inlets and outlets are located at both ends of the housing; through holes are opened at the left and right ends of the housing 1, and the There is an annular groove on the through hole; both ends of the inner cyli...

Abstract

The invention relates to a heat exchanger, in particular to a heat exchanger for viscous fluid with poor liquidity. The heat exchanger can be used for the fields of chemical engineering, petrochemical industry, food, medicine, papermaking, ships and the like and comprises a shell, an inner barrel, a motor, a heat exchange medium a, a heat exchange medium b, a bearing a and a bearing b; a fluid inlet and an outlet are arranged at the upper end and the lower end of the shell and are located at two ends of the shell; through holes are arranged at the left end and the right end of the shell, and annular grooves are arranged on the through holes; two ends of the inner barrel are necking structures; the heat exchange surface is capable of rotating, so that heat exchange area is increased, disturbance is improved so as to strengthen heat exchange, and the heat exchange medium a and the heat exchange medium b do not permeate to each other; and as hermetic connection between a rotating pipeline and an outer barrel is in non-elastic contact dynamic sealing, mutual permeation of the two heat exchange media can be prevented.
