Abstract
A screwed and grooved flat tube provides a solution to the impact of low temperature gradient and slow heat transfer to the refrigerating effectiveness of the existing screwed and grooved round tube. A tube is provided with a screwed groove arranged on the surface, which is characterized in the flat structure and a larger surface area ratio. As per the same coefficient of heat transfer, this screwed and grooved flat tube has a greater amount of transferred heat. Moreover, in comparison with the round tube, the flat tube greatly reduces the distance from the fluid centre to the tube wall and increases the temperature gradient. Thereby the heat energy in the fluid centre can be transferred out much easier with high transfer efficiency.
Description
Technical field
The utility model relates to the cooler of vehicle motor with managing particularly a kind of helical groove flat tube.
Background technology
At present, the helical groove pipe is used for the cooler that various vehicle motors adopt.Existing helical groove pipe is a pipe, by be provided with helical groove on pipe, can strengthen the turbulence level of main flow fluid, improves heat transfer efficiency.But because fluid centre-to-centre spacing tube material and tube wall distance is bigger, so thermograde is little, and heat energy outwards transmits slow, influences cooling effect.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of thermograde big, the helical groove flat tube that heat transfer efficiency is high.
The utility model is achieved in that it has a body, is provided with helical groove on the body surface, and its special character is: described body is a flat.
Above-mentioned helical groove flat tube, the macropinacoid of described body periphery are arc surface.
The utility model has the advantages that: because body is a flat, the surface area ratio of body increases, and under the identical situation of heat transfer coefficient, the heat output of this helical groove flat tube can be bigger.Simultaneously, because the distance of fluid centre-to-centre spacing body tube wall is dwindled greatly than circular pipe, thermograde increases, just easier outside transmission of the heat energy at fluid center like this, heat transfer efficiency height.
