Description

Double pipe heat exchanger

Technical field:

The utility model relates to the energy exchange device, and specifically a kind of hot water or cold water of being specially adapted to carries out the double pipe heat exchanger of energy exchange.

Background technology:

As everyone knows, liquid heat-exchanger is a kind of a kind of device that obtains heat energy by certain medium indirectly from thermal source, be widely used in industrial production and daily life, traditional heat exchanger is generally plate type heat exchanger, it is made up of the multilayer blade, because this heat transfer process all is to carry out under the bigger situation of pressure ratio, solving problem of withstand voltage is the key technology problem that heat exchanger is produced.Because plate type heat exchanger is in order to overcome the internal pressure problem, all designed thicker shell, guarantee withstand voltage problem with thickness, to guarantee its safe operation, volume is big, feed consumption is many so such heat exchanger must form, technology complicated problems relatively, and equipment investment is big, production cost is high, and product price is high, has influenced the expansion in market.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, has made full use of the big advantage of metal material tensile strength and has overcome internal pressure, and a kind of good pressure-resistant performance is provided, and heat exchange area is big, the high double pipe heat exchanger of heat exchange efficiency.

The utility model can reach by following measure:

A kind of double pipe heat exchanger, be provided with sleeve pipe, the two ends of sleeve pipe are respectively equipped with upper and lower gripper shoe, the tube wall of sleeve pipe is provided with water inlet pipe and outlet pipe, it is characterized in that being provided with in the sleeve pipe interior pipe, in the pipe two ends be connected with upper and lower gripper shoe respectively, be respectively equipped with water inlet pipe and outlet pipe on upper and lower gripper shoe and the end face that interior pipe is connected.

The water inlet pipe in the utility model on the gripper shoe and the diameter of outlet pipe are less than the diameter of interior pipe, so that liquid in the interior Guan Youyi section holdup time, fully absorbs the energy of liquid outside the interior pipe, in the sleeve pipe.

The utility model is owing to adopt said structure, formed between two pipes and interior pipe in the inside two cavitys, cavity under the normal condition between two pipes is the space of heat source fluid, interior pipe the inside is the space that is heated fluid, have good pressure-resistant performance, advantages such as heat exchange area is big, heat exchange efficiency is high, scientific structure, technology is simple, materials are few, equipment investment is few, production cost is low, product price is held susceptible to user acceptance, and the market expansion is fast.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

As shown in drawings, a kind of double pipe heat exchanger, be provided with sleeve pipe 1, the two ends of sleeve pipe 1 are respectively equipped with, lower supporting plate 4,6, the tube wall of sleeve pipe 1 is provided with water inlet pipe 3 and outlet pipe 7, water inlet pipe 3 and outlet pipe 7 have the interface of screw, pipe 2 in it is characterized in that being provided with in the sleeve pipe 1, interior pipe 2 two ends are respectively with last, lower supporting plate 4,6 are connected, on, lower supporting plate 4,6 with end face that interior pipe 2 is connected on be respectively equipped with water inlet pipe 5 and outlet pipe 8, the water inlet pipe 5 in the utility model on the gripper shoe and the diameter of outlet pipe 8 are less than the diameter of interior pipe 2, so that liquid is in the interior Guan Youyi section holdup time, fully absorb outside the interior pipe, the energy of liquid in the sleeve pipe, so just formed between two pipes and interior pipe in the inside two cavitys, cavity under the normal condition between two pipes is the space of heat source fluid, interior pipe the inside is the space that is heated fluid, when heat source fluid when an end of outer tube enters the space of flowing through between two pipes, interior pipe is heated, cold conditions (relatively) fluid from an end enter flow through in pipe the time just heated by inner tubal wall, so just realized the purpose of heat exchange.It can also the in parallel as required or use that is together in series simultaneously.

Claims

1, a kind of double pipe heat exchanger, be provided with sleeve pipe, the two ends of sleeve pipe are respectively equipped with upper and lower gripper shoe, the tube wall of sleeve pipe is provided with water inlet pipe and outlet pipe, it is characterized in that being provided with in the sleeve pipe interior pipe, in the pipe two ends be connected with upper and lower gripper shoe respectively, be respectively equipped with water inlet pipe and outlet pipe on upper and lower gripper shoe and the end face that interior pipe is connected.

2, a kind of double pipe heat exchanger according to claim 1 is characterized in that the diameter of the diameter of water inlet pipe on the gripper shoe and outlet pipe less than interior pipe.
