Abstract

The utility model discloses a radiating tube for cooling water tank of heavy-duty engine, belonging to the technical field of internal-combustion engine water cooling equipment, particularly a radiating tube for cooling water tank of heavy-duty automobile engine or diesel engine used for field operations such as large strip mine, oil field and the like. The technical scheme of the utility model is that: a flat copper tube is arranged between an upper end and a lower end of a copper tube, two planes on the left and right of the flat copper tube are externally provided with two radiating fin groups which are folded in continuous S shape, the surfaces of the radiating fins of the radiating fin groups are provided with convex roller impressions, and the planes at both sides of the flat copper tube are connected with the radiating fin groups as a whole; the thickness of the copper radiating fins is 0.04 to 0.1mm, the crest height of the continuous S-shaped radiating fin groups is 4 to 12mm, the pitch of wave is 1.5 to 6mm, and the width of the radiating fin groups is 5 to 30mm. The radiating tube has the advantage that: the radiating fins on the radiating tube are not perforated, effective radiating area is increased and accordingly, cleaning is easier. The convex impressions of the radiating fins can increase air turbulence while playing the role of reinforcing ribs to enhance mechanical strength.

Description

A kind of heavy-duty engine cooling water tank radiating tube

Technical field

The utility model belongs to internal combustion engine water cooling equipment technical field, the heavy-duty car engine of field works such as particularly a kind of glory-hole and oil field or the cooling water tank radiating tube of diesel engine.

Background technology

The structure and the used radiating tube basically identical of common engine cooling water tank of the radiating tube of the interior use of the heavy-duty car engine of field works such as glory-hole and oil field or diesel coolant case at present, promptly fold the fin of making in the welding of copper pipe outside by copper sheet, perforate is flowed to increase air on fin.But perforate must reduce the mechanical strength of copper sheet on the fin.Simultaneously this louvre is easy in the very big place of dust stop up, and is subjected to the external force distortion that lodges easily, and is not easy to clean, thereby can lower radiating efficiency, uses damage easily under the inclement condition situation, has influence on the normal operation of vehicle.

Summary of the invention

The purpose of this utility model is to change the structure of fin on the radiating tube to overcome aforesaid drawbacks.

The technical solution of the utility model is: be the pancake copper pipe between copper pipe upper end and copper pipe lower end, outside two planes two groups of fins that are folded into continuous S type are arranged about it, protruding roll mark is arranged on the fin surface on the groups of fins, and flat copper tube is connected as a single entity at two side plane places and groups of fins; The copper sheet thickness of fin is 0.04-0.1mm, and S type groups of fins crest height is 4-12mm continuously, and the pitch of waves is 1.5-6mm, and the groups of fins width is 5-30mm.

The beneficial effects of the utility model: because fin does not punch on the radiating tube, increased the efficiently radiates heat area, and cleaning is easier.The protruding roll mark of fin can increase air disturbance, has increased mechanical strength simultaneously.

Description of drawings

Accompanying drawing 1 is the utility model structural representation.

The specific embodiment

Between copper pipe upper end 1 and copper pipe lower end 2, be pressed into pancake copper pipe 3, copper pipe upper end 1 requires to decide on concrete water tank with the length and the copper pipe diameter of copper pipe lower end 2, in the pancake copper pipe 3 is cooling-water duct, two plane outside welds are connected to two groups of fins 4 that are folded into continuous S type about it, and all rolling on each fin 5 surface on the groups of fins 4 have a protruding roll mark.Groups of fins 4 and fin 5 are made for same copper sheet, and its thickness is 0.04-0.1mm, and wherein continuous S type groups of fins 4 crest heights are 4-12mm, and the pitch of waves is 1.5-6mm, and groups of fins 4 width are 5-30mm.Because fin 5 no longer punches, and has increased the efficiently radiates heat area, and be difficult for stopping up, cleaning is more prone to.The protruding roll mark of fin 5 also can increase air disturbance, improves radiating efficiency.The fin roll mark plays the effect of reinforcement simultaneously, thereby has increased mechanical strength.
