Description

A kind of double pipe heat exchanger
Technical field
It the utility model is related to mechanical field, and in particular to a kind of double pipe heat exchanger.
Background technology
Both known about in mechanical seal field, to avoid mechanical seal from being damaged because temperature is too high, need to just use temperature relatively low Flushing liquor is not stopped to rinse to the annular seal space of mechanical seal, to cool to mechanical seal end surface.And to ensure to rinse The temperature of liquid is relatively low, needs to cool to flushing liquor using heat exchanger again.
At present, because the contact surface of coolant and heat exchanger tube only has the outer surface of heat exchanger tube, heat exchange area is smaller so that changes The thermal efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of double pipe heat exchanger, caused above-mentioned more in the prior art to solve Item defect.
A kind of double pipe heat exchanger, including inner and outer tubes, connected by the bend pipe of U-shaped between said inner tube, it is described outer Pipe is fixed and forms closed cavity on inner pipe and between inner tube, is provided with expansion joint in the middle part of the outer tube, adjacent outer tube it Between connected by communicating pipe one, the outer wall of the outer tube is provided with the heat transmission fin in circumferential array, in one of inner tube also It is provided with temperature sensor provided with a flange, in flange, passes through the communicating pipe of U-shaped between the outer tube at flange both ends Two connections.
Preferably, connected between said inner tube and bend pipe by adpting flange one.
Preferably, the side of the heat transmission fin is provided with arcwall face.
Preferably, connected between the communicating pipe one by adpting flange two.
Preferably, the heat transmission fin is specifically made up of aluminium alloy plate.
The utility model has the advantage of:Heat exchanger of the present utility model can be passed through conductive fluid into outer tube, for internal Liquid in pipe is exchanged heat, the design of the heat transmission fin of use so that the heat exchange efficiency of this heat exchanger is high, is connected firmly, and leads to The temperature conditions of liquid in inner tube can be detected in real time by crossing described temperature sensor, be easy to manage, and compact overall structure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is along the sectional view in A-A directions in Fig. 1.
Wherein, 1- inner tubes, 2- outer tubes, 3- bend pipes, 4- expansion joints, 5- communicating pipes one, 6- heat transmission fins, 7- flanges, 8- temperature sensors, 9- communicating pipes two, 10- adpting flanges one, 11- adpting flanges two.
Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below With reference to embodiment, the utility model is expanded on further.
As depicted in figs. 1 and 2, a kind of double pipe heat exchanger, including inner tube 1 and outer tube 2, U-shaped is passed through between said inner tube 1 Bend pipe 3 connect, the outer tube 2 is fixed in inner tube 1 and closed cavity is formed between inner tube 1, and the middle part of the outer tube 2 is set There is expansion joint 4, connected between adjacent outer tube 2 by communicating pipe 1, the outer wall of the outer tube 2 is provided with circumferential array Heat transmission fin 6, a flange 7 is additionally provided with one of inner tube 1, temperature sensor 8, interface method are provided with flange 7 Connected between the outer tube 2 at blue 7 both ends by the communicating pipe 29 of U-shaped.
In the present embodiment, connected between said inner tube 1 and bend pipe 3 by adpting flange 1.
In the present embodiment, the side of the heat transmission fin 6 is provided with arcwall face, and the heat transmission fin 6 is specifically by aluminium alloy Plate is made.
In addition, connected between the communicating pipe 1 by adpting flange 2 11.
Based on above-mentioned, heat exchanger of the present utility model can be passed through conductive fluid into outer tube 2, for the liquid in inner tube 1 Exchanged heat, the design of the heat transmission fin of use so that the heat exchange efficiency of this heat exchanger is high, is connected firmly, passes through described temperature Degree sensor can detect the temperature conditions of liquid in inner tube 1 in real time, be easy to manage, and compact overall structure.
As known by the technical knowledge, the utility model can pass through other essence without departing from its spirit or the reality of essential feature Scheme is applied to realize.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only 's.It is all in the scope of the utility model or in the change being equal in the scope of the utility model by the utility model bag Contain.
