Abstract
The utility model relates to the technical field of heat exchangers, and in particular relates to a tubular heat exchanger. The tubular heat exchanger comprises a thick pipe which is communicated with heat-conducting media, wherein a plurality of parallel thin pipes are arranged in the thick pipe and the thin pipes are connected through U-shaped pipes. According to tubular heat exchanger disclosed by the utility model, products flow in the thin pipes; heating media flow in the thick pipe; the heat exchange is carried out through the walls of the thin pipes; the quantity and the diameter of the thin pipes in each thick pipe are changeable so as to meet the requirements on properties and heat quantities of the products; supports are adopted to ensure the heat-conducting media to be capable of producing turbulent flow, so that the heat transfer efficiency between the products and the media can be relatively high; and fluid in the tubular heat exchanger can flow in two opposite flow directions, i.e. forward flow and counter flow, the forward flow is capable of saving the equipment cost and the counter flow is capable of saving the operation cost.
Description
Technical field
The utility model relates to a kind of heat exchanger, specifically is a kind of tubular heat exchanger.
Background technology
Heat exchanger is with the equipment of the part heat transferred cold fluid of hot fluid, claims heat exchanger again.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies critical role aborning.And air-conditioning is limited by spatial constraints, and its heat exchanger specific area is not high, thereby heat exchange efficiency can't satisfy the demands.
Summary of the invention
The primary and foremost purpose of the utility model is to provide a kind of tubular heat exchanger of effective raising heat exchange efficiency, and for realizing above-mentioned purpose, the concrete scheme of the utility model is following:
A kind of tubular heat exchanger comprises extra heavy pipe, and said extra heavy pipe is communicated with heat-conducting medium; Be provided with some parallel tubules in the said extra heavy pipe, connect through the U-shaped pipe between the said tubule.
Preferably, be provided with support in the said extra heavy pipe, said tubule is fixed in the said extra heavy pipe through support.
The tubular heat exchanger that the utility model provides, goods flow at tubule, and heat medium flows at extra heavy pipe, carries out heat exchange through tubule wall.The quantity and the diameter of the tubule in every extra heavy pipe can change, to satisfy goods character and to the requirement of heat; Support can make heat-conducting medium produce turbulent flow; Can make between goods and the media heat transmission reach higher efficient like this; And the relative current of the fluid in the tubular heat exchanger is to there being two kinds of following current and adverse currents, and the former can save installation cost, and the latter can save operating cost.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:
Fig. 1 is the utility model example structure sketch map.
The specific embodiment
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.
Embodiment
As shown in Figure 1, a kind of tubular heat exchanger comprises extra heavy pipe 1, and said extra heavy pipe 1 is communicated with heat-conducting medium; Be provided with some parallel tubules 2 in the said extra heavy pipe 1, promptly 1 li some little tubules 2 be housed at a bigger extra heavy pipe of diameter, these tubules 2 are fixed on the tube sheet at two ends, connect through U-shaped pipe 3 between the said tubule 2.
The foregoing description scheme, goods flow at tubule 2, and heat medium is in extra heavy pipe 1 reverse flow; Carry out heat exchange through tubule 2 walls, tubule 2 quantity and diameter in every extra heavy pipe 1 can change, to satisfy goods character and to the requirement of heat; Extra heavy pipe 1 adopts air supported head and double containment design; Thereby do not have stress that thermal expansion causes and avoid risk of pollution, be convenient to opening conduits simultaneously and check and keep in repair, more can bear high product pressure.
As the improvement of the foregoing description scheme, be provided with support (not indicating) in the said extra heavy pipe 1, said tubule 2 is fixed in the said extra heavy pipe 1 through support.Support can make heat-conducting medium produce turbulent flow, can make like this that heat transmission reaches higher efficient between goods and the media.
In the foregoing description, the relative current of fluid is to two kinds of following current and adverse currents are generally arranged in the tubular heat exchanger: during following current, the temperature difference of porch two fluids is maximum, and reduces gradually along heating surface, and the temperature difference is minimum to the exit; During adverse current, along the temperature difference distribution uniform of heating surface two fluids; Under the certain condition of the out temperature of cold and hot fluid; When two kinds of fluids did not all have phase transformation, minimum with the maximum following current of the mean temperature difference of adverse current, tubular heat exchanger was under the condition of accomplishing same heat output; Adopt adverse current that mean temperature difference is increased, the heat transfer area of heat exchanger reduces; If heat transfer area is constant, the consumption of heating or cooling fluid is reduced.The former can save installation cost; The latter can save operating cost; So should adopt countercurrent flow as far as possible in design or in produce using. pipe heat exchanger when cold and hot fluid both or wherein a kind of when thing phase change (boiling or condensation) is arranged, only emit during owing to phase transformation or absorb the latent heat of vaporization, the temperature of fluid itself and no change; Therefore the out temperature of fluid equates, at this moment the temperature difference of two fluids is just selected irrelevant with the flow direction of fluid.Except that following current and these two kinds of flow directions of adverse current, also have the flow directions such as cross-flow and baffling, tubular heat exchanger reduces the thermal resistance in the dividing wall type heat exchanger in diabatic process, be an important problem to improve heat transfer coefficient.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
