Description

A kind of car radiation pipe

Technical field

The utility model belongs to technical field of automobile, and in particular to a kind of car radiation pipe.

Background technology

Automobile radiators are indispensable important components in automobile water-cooling engine-cooling system, by intake chamber, water outlet The part of room and radiator core etc. three is constituted；Wherein radiator core is the core of radiator, mainly plays thermolysis, radiator Core by radiating tube, fin (or heat-radiation belt), up and down main leaf etc. constitute.When radiator works, coolant flows in radiator core Dynamic, air passes through outside radiator, and coolant occurs heat exchange with air and realizes radiating：The coolant of heat is flowed into from engine end Radiate and turn cold via air, and coolant circulation system is flowed back into from water-supplying chamber.

Existing radiation tube structure with heat is various, in use, is easy to occur heat with extraneous close to the coolant of radiating inside pipe wall Exchange, quick heat radiating can be obtained；And the coolant in the radiating tube Central Line apart from radiating pipe wall farther out, it is impossible to the external world Direct heat-shift, can only by the coolant of periphery indirectly with extraneous heat-shift, therefore its radiating effect is poor, radiating effect Rate is relatively low.

Utility model content

The utility model is intended to provide a kind of car radiation pipe, and to solve, existing radiating tube radiating effect is poor, radiates and imitates The problem of rate is low.

Central tube, central tube and body tube are coaxially provided with car radiation pipe in this programme, including body tube, body tube Between be fixedly connected by least one thermally conductive sheet, body tube cross sectional shape is oblateness, and central tube is identical with body tube shape, Body inside pipe wall is provided with multiple row shape identical radiation tooth.

The know-why of this programme is：This programme includes body tube, and coolant enters wherein, and wherein from intake chamber Flowing, occurs heat exchange with the external world by body tube wall and radiates；Central tube is coaxially provided with body tube, in body tube Coolant near heart line, can directly conduct heat to the inner and outer wall of central tube, and by fin that these are hot Then amount conduction is dispersed into air to body tube.Radiator is located at engine front on automobile, and radiating tube keeps flat setting, During traveling, oblate section can improve driveability to reduce air drag；And increase heat transfer area, increase Radiating effect.Central tube is identical oblate section with body tube, and both each walls are parallel so that radiating tube shape Rule, while beneficial to coolant flow.Multiple row radiation tooth is set, body inside pipe wall and the contact surface of coolant is effectively increased Product, improves radiating efficiency.

This programme has technical effect that：This programme is provided with central tube so that the coolant center section of flowing is direct Heat is outwardly transmitted by central tube, gradually radiated compared to the coolant by periphery, with good radiating effect, and Radiating efficiency is high.

The following is the preferred scheme based on such scheme：

Preferred scheme one：Based on base case, the thermally conductive sheet between the central tube and body tube has four.Four heat conduction Piece adds the contact area with coolant, improves heat transfer radiating effect.

Preferred scheme two：Based on preferred scheme one, four thermally conductive sheets are in crossing distribution.Its cross on section Distribution so that radiating tube construction rule, and the flow resistance to coolant is reduced to greatest extent.

Preferred scheme three：Based on preferred scheme two, four thermally conductive sheets are set along body tube axis direction.In longitudinal direction On along body tube axis so that radiating tube construction rule, and reduce the flow resistance to coolant to greatest extent.

Preferred scheme four：Based on preferred scheme three, each column radiation tooth cross sectional shape is triangle.Body inside pipe wall is set The radiation tooth of multiple row triangle is put, the contact area of body inside pipe wall and coolant is effectively increased, radiating is further increased Effect.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

The utility model is described in further detail below by embodiment：

Reference in Figure of description includes：Body tube 1, radiation tooth 2, thermally conductive sheet 3, central tube 4.

As shown in figure 1, a kind of car radiation pipe, including section are in be coaxially provided with oblate body tube 1, body tube 1 With its shape identical central tube 4, it is fixedly connected between central tube 4 and body tube 1 by four thermally conductive sheets 3；Four thermally conductive sheets 3 It is in crossing distribution on cross section, in the vertical along the axis of body tube 1；Meanwhile, the inwall of body tube 1 is additionally provided with multiple row and cut Face is the radiation tooth 2 of triangle, and the length direction of radiation tooth 2 is along the axis direction of body tube 1.

This radiating tube keeps flat setting as a part for cross-flow radiator in radiator, at its two more flat face In on horizontal plane；Radiator is arranged on engine front on automobile, by radiating tube and air occur heat exchange cause wherein from The hotter coolant that engine end is flowed into is cooled, then passes back into coolant circulation system, realizes the cooling of engine system.

When car radiation pipe works, hot coolant flows in body tube 1, its periphery and the tube wall of body tube 1 Contact, so as to be radiated by the tube wall of body tube 1 into air；Inner and outer wall of the center portion thereof point then with central tube 4 is contacted, and is led to The inner and outer wall of central tube 4, four thermally conductive sheets 3 is crossed to conduct heat to body tube 1, then radiate into air.Due to cooling Liquid periphery and core all have thermal conducting path, therefore with good radiating effect；The setting of central tube 4 makes simultaneously Obtaining the heat of coolant core can conduct to air quickly through central tube 4, thermally conductive sheet 3 and body tube 1, compared to logical The coolant conduction of periphery is crossed, its radiating efficiency is high.

Meanwhile, the multiple row triangle radiation tooth 2 on the inwall of body tube 1 effectively increases the inwall of body tube 1 and coolant Contact area, further increases radiating effect.Also, because radiating tube section is in oblateness, therefore in vehicle traveling process In, air drag is effectively reduced in its relatively round side, beneficial to running car；On the other hand, its two more flat side and flowing Air there is larger contact area, therefore, it is possible to effectively improve radiating effect.

Above-described is only the known general knowledge such as concrete structure and/or characteristic in embodiment of the present utility model, scheme Excessive description is not made herein.It should be pointed out that for a person skilled in the art, before the utility model structure is not departed from Put, several modifications and improvements can also be made, these should also be considered as protection domain of the present utility model, and these are all without shadow Ring effect and practical applicability that the utility model is implemented.
