CN2663904Y - A heat exchanger - Google Patents

Abstract

The utility model provides a heat exchanger, comprising an upper shell, a lower shell, an intermediate shelf, a heat tube, a heated medium inlet, a heated medium outlet, a heating medium inlet and a heating medium outlet, etc., wherein the heat tube is fixed on the intermediate shelf, the upper end of the heat tube inserts into the heated medium and the lower end inserts into the heating medium; the heat tube is filled into heat transfer medium and vacuumized; on heating, the heat transfer medium inside the heat tube under the condition of vacuum becomes steam which rises to the upper end and transfers heat into the heating medium; on meeting cold, the steam inside the heat tube becomes liquid to reflow into the lower end of the heat tube; through such repetition, the utility model achieves the goal of high-efficient heating and energy conservation.

Description

A kind of heat exchanger

Technical field

The utility model relates to a kind of heat exchanger that is applicable to industry production devices such as thermoelectricity, oil, chemical industry.

Background technology

Existing heat exchanger generally is divided into the structure of upper and lower cylindrical shell, and the centre is separated by shelf, and heated medium flows in upper shell, and heat medium is middle reverse flow in lower shell, and heated medium and heat medium conduct heat by intermediate shelf.Because contact area is little, thereby heat transference efficiency is low, energy consumption is big.

Summary of the invention

The purpose of this utility model is to provide a kind of heat transfer efficiency height, is convenient to clean maintenance, the shell pipe type heat exchanger that cost is low.

Heat exchanger of the present utility model is made up of upper shell, lower shell, intermediate shelf, heat pipe, heated medium inlet, heated medium outlet, heat medium inlet, heat medium outlet etc.Heat pipe is fixed on the intermediate shelf, has good sealing with being connected of intermediate shelf, thereby guarantees to go up the sealing of lower shell, and the upper end of heat pipe is inserted in the heated medium, and the lower end is inserted in the heat medium.Be filled with heat transfer medium (oil or water) in the heat pipe, vacuumize simultaneously.Heated medium flows in upper shell, and heat medium is middle reverse flow in lower shell.When heat pipe was heated, the heat transfer medium in the heat pipe became steam and rises to the upper end under the situation of vacuum, heat is passed to heated medium, steam becomes liquid again under the cold situation and flows back to the heat pipe lower end meeting in the heat pipe, so repeatedly, reaches efficient heating and purpose of energy saving.

The radical of heat pipe and spacing are determined according to the heat exchange amount of heat exchanger.

As a kind of improvement of the present utility model,, is furnished with fin on surface, heat pipe place in order further to improve heat exchange efficiency.

Description of drawings

The specific embodiment

Upper shell 5, lower shell 9 separate by intermediate shelf 7, heat pipe 1 is inserted on the intermediate shelf 7, heated medium flows into upper shell 5 by heated medium inlet 2, flow out from heated medium outlet 6, heat medium flows into lower shell 9 by heat medium inlet 8, flow out from heat medium outlet 4, be distributed with fin 10 on the heat pipe 1.Be filled with conduction oil in the heat pipe 1, and vacuumize, when being heated, conduction oil in the heat pipe becomes the upper end that steam rises to heat pipe 1, heat is passed to heated medium, and the cold liquid that becomes of conduction oil chance flows back to the heat pipe lower end simultaneously, and so moving in circles reaches the purpose of efficient heating heated medium.

Claims (2)

1, a kind of heat exchanger is made up of upper shell (5), lower shell (9), intermediate shelf (7), heated medium inlet (2), heated medium outlet (6), heat medium inlet (8), heat medium outlet (4) etc., it is characterized in that: the heat pipe (1) that inside is filled with heat transfer medium is housed on the intermediate shelf (7), the upper end of heat pipe (1) is inserted in the upper shell (5), and the lower end is inserted in the lower shell (9).

2, heat exchanger according to claim 1 is characterized in that being furnished with fin (10) on heat pipe (1).
