Description

Technical Field

[0001] The utility model relates to a radiator, in particular to a radiator of an internal combustion engine generator set with a fan guard reinforced with folded edges and lining ribs, belonging to the technical field of radiators. Background Art

[0002] Internal combustion engine generator sets with closed-loop cooling systems rely on radiators for cooling. The engine uses a fan to blow air in a forward direction, cooling both the cooling water circulating within the radiator's water core assembly and the high-temperature turbocharged air generated by the turbocharger within the intercooler core assembly. When the unit is powered by a 50Hz or 60Hz frequency, the internal combustion engine typically operates at a high speed of 1500 or 1800 rpm. The variable speed drive typically rotates the fan at an angular velocity of approximately 1000 or 1200 rpm. This requires the installation of a fan guard between the radiator fan and the internal combustion engine to prevent human body parts or other objects from coming into contact with the fan, thereby preventing personal injury and equipment damage.

[0003] With the rapid development of internal combustion engine manufacturing technology, the power of a single generator set has continued to increase, and the overall dimensions of the radiator have also increased accordingly. As a result, the dimensions of the accompanying fan shroud have also increased. Large fan shrouds are often divided into two parts, fixed to the radiator support side panels and the air guide cover. This has brought two problems: first, the fan shroud uses more material and increases weight; second, the fan shroud vibrates and generates noise. Accordingly, two key performance improvements and optimizations are needed: achieving product lightweighting and reducing operating vibration and noise. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a radiator of an internal combustion engine generator set with a folded edge lining reinforcement type fan guard.

[0005] The technical solution adopted in this utility model is:

[0006] A folded-edge rib reinforced fan guard radiator for an internal combustion engine generator set, comprising a supporting frame, a heat dissipation water core assembly, an intercooler core assembly, an air guide cover, a fan guard and a mounting base, the heat dissipation water core assembly being provided with a water inlet and a water outlet, the intercooler core assembly being provided with an air outlet and an air inlet, the fan guard comprising a right guard and a left guard that cooperate with each other, the connection between the right guard and the left guard being provided with a fixed folded edge, the right guard and the left guard being provided with fixed reinforcing ribs that intersect vertically in the longitudinal and transverse directions, a gap for accommodating a fan being formed between the inner lower parts of the right guard and the left guard, the inner gaps of the right guard and the left guard being provided with pulley guards, a plurality of parallel rectangular holes being provided on the front end faces and side faces of the right guard and the left guard, and connecting mesh ribs being provided on the rectangular holes.

[0007] As a further improvement of the above technical solution, an adjustable reinforcing rib is placed horizontally above the notch, and a plurality of adjusting waist-shaped holes are arranged on the adjustable reinforcing rib along the length direction. The adjusting waist-shaped holes are connected to the right guard shield and the left guard shield by bolts.

[0008] As a further improvement of the above technical solution, the outer sides of the right and left shields are provided with mounting folds that match the support frame.

[0009] As a further improvement of the above technical solution, the water inlet and water outlet of the heat dissipation water core assembly are respectively connected to the water outlet and water inlet of the cylinder liner water chamber of the internal combustion engine to form a heat dissipation cooling circuit.

[0010] As a further improvement of the above technical solution, the air inlet and the air outlet of the intercooler core assembly are respectively connected to the air outlet of the turbocharger and the air inlet of the internal combustion engine combustion chamber to form a drop.

[0011] The advantages of the utility model are:

[0012] The utility model has a simple structure and is easy and quick to install. By punching a number of parallel rectangular holes on the surface of the fan guard and arranging connecting mesh ribs on the rectangular holes, it is beneficial to ventilation and heat dissipation, and can also reduce the weight of the fan guard, thereby achieving a lightweight effect of the product; fixed reinforcing ribs that intersect vertically are arranged in the horizontal and vertical directions inside the fan guard, and an adjustable reinforcing rib plate is placed horizontally above the notch, so that the overall rigidity of the fan guard is good, vibration is reduced, and noise is reduced.
