Abstract
The utility model relates to a heat exchanger coil with an inner rib, which comprises a flat tube, and is characterized in that the inner rib connected with a vertical tube wall of the flat tube is arranged in the middle of the flat tube in the short axis direction. The heat exchanger coil with the inner rib has the advantages of being capable of greatly enhancing stress resistance of the flat tube, guaranteeing shape stability during processing, and enabling fin penetration to be performed smoothly.
Description
Technical field
The utility model relates to a kind of heat exchanger coils with internal-rib.
Background technology
The littler flat tube of windage when the coil pipe in the widely used heat exchanger is brought into use heat exchange in refrigeration industry at present, though use the back heat exchange efficiency to improve greatly, because coil pipe is a flat; The distortion that is crushed easily of flat horizontal surface after it is stressed; Adding man-hour, particularly when wearing radiating fin, flat tube deforms easily and causes wearing the fin failure; Therefore need improve flat tube, to improve its crushing resistance.
Summary of the invention
The purpose of the utility model is the problem that solves the existing easy deformation of crushing resistance difference of heat exchanger use flat tube in the prior art; A kind of heat exchanger coils with internal-rib is provided; A kind of heat exchanger coils of the utility model design with internal-rib; Comprise flat tube, it is characterized in that: be provided with in the centre of the short-axis direction of flat tube one with the flat tube internal-rib that links to each other of tube wall up and down.The utility model has the advantages that the anti-pressure ability that can strengthen flat tube greatly, guarantee adding the dimensional stability in man-hour, make and wear fin and can carry out smoothly.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment
Comprise flat tube 1 among the figure, it is characterized in that: be provided with in the centre of the short-axis direction of flat tube one with the flat tube internal-rib 2 that links to each other of tube wall up and down.
Because the tube wall of flat tube on short-axis direction deforms when stressed easily, therefore in process, take place easily to be out of shape because of external force, and because flat tube need carry out penetrating of radiating fin; Their size cooperates again very accurate; As long as flat tube deforms a little and then can cause penetrating failure, flat tube is scrapped, and behind the internal-rib that has increased short-axis direction; The anti-pressure ability of this face improves greatly; Generally run on the minor axis wall that external force acts on flat tube, flat tube can not deform yet, and can guarantee carrying out smoothly when flat tube is worn fin.
