Description

Technical Field

[0001] The utility model relates to the technical field of tractor cooling systems, in particular to a tractor cooling bag. Background Art

[0002] The heat dissipation package assembly is the core component of the tractor's cooling system. The heat dissipation package assembly usually includes sub-radiators such as water-cooled radiators, oil-cooled radiators, intercoolers and condensers. Most of the above sub-radiators are arranged in multiple layers in front and back. The cold air on the front side of the heat dissipation package passes through the heat dissipation package backwards under the action of the suction fan. The cold air takes away the heat of the heat dissipation package and the medium flowing through the heat dissipation package is cooled. Limited by the layout space of the vehicle hood, each sub-radiator is placed vertically, the gap between layers is small, and there is a lack of maintenance and operation space, which makes the maintenance of each layer of sub-radiators difficult. At the same time, due to the limited front windward area of ​​the heat dissipation package, the temperature rises during the backward flow of cold air, and the heat dissipation speed of the rear sub-radiator decreases, resulting in the problem of insufficient heat dissipation performance of some sub-radiators. Utility Model Content

[0003] The technical problem to be solved by the utility model is: how to reduce the difficulty of maintenance of each sub-radiator in the heat dissipation package.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0011] Furthermore, a sealing plate is provided on the outer side of the connecting side plate, and both the left and right sides of the water-cooled radiator are connected to the sealing plate.

[0012] It is convenient to close the side of the gap on the front side of the water-cooled radiator to prevent cold air from entering the front side of the water-cooled radiator from the side, thereby ensuring the ventilation volume of the intercooler and the oil-cooled radiator; at the same time, it prevents debris from entering the front side of the water-cooled radiator from the side, thereby increasing the service life of the heat dissipation pack.

[0013] Furthermore, the intercooler is connected to the upper part of the connecting side plate by screws; the oil-cooled radiator is connected to the lower part of the connecting side plate by screws; the oil-cooled radiator and the water-cooled radiator are both connected to the connecting bottom plate by screws; the water-cooled radiator is connected to the sealing plate by screws.

[0022] The wind guide cover can cooperate with the suction fan to gather the wind force of the suction fan to form axial flow wind, thereby increasing the air volume passing through the heat dissipation package and improving the heat dissipation performance.

[0023] Furthermore, the upper and lower parts of the fuel radiator are respectively provided with connecting strips, and both ends of the connecting strips are fixed to the front side of the intercooler.

DETAILED DESCRIPTION

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] This utility model refers to Figure 1-3 .

[0034] The utility model provides a tractor heat dissipation package, comprising a sheet metal bracket, an intercooler 1, a water-cooled radiator 2 and an oil-cooled radiator 4 are fixed on the sheet metal bracket, the intercooler 1 and the oil-cooled radiator 4 are both located on the front side of the water-cooled radiator 2, the intercooler 1 is located on the upper side of the oil-cooled radiator 4, and gaps are respectively provided between the intercooler 1 and the oil-cooled radiator 4 and the water-cooled radiator 2; a fuel radiator 3 is provided on the front side of the intercooler 1; a guide rail bracket is provided on the front side of the oil-cooled radiator 4, and a condenser 5 is slidably connected to the guide rail bracket.

[0035] principle:

[0036] Intercooler 1, water cooling radiator 2, fuel cooling radiator 3, oil cooling radiator 4 and condenser 5 are all sub-radiators in the tractor cooling package; the above sub-radiators are all prior art. Intercooler 1 is used to cool the high-temperature gas from the engine supercharger, water cooling radiator 2 is used to cool the high-temperature water from the engine, fuel cooling radiator 3 is used to cool the high-temperature fuel returned to the fuel tank by the engine, oil cooling radiator 4 is used to cool the high-temperature hydraulic oil of the chassis, and condenser 5 is used to cool the refrigerant used by the air conditioner in the cab.

[0037] Note: The front and rear sides of each sub-radiator are ventilated grille structures. The structure of the sub-radiator is irrelevant to the technical problem solved by the present invention, so the grille structure is omitted in the attached drawings to make the lines of the drawings simple and easy to identify the positional relationship of each sub-radiator.

[0038] During installation, the suction fan in the tractor cooling system is located at the rear side of the cooling package. When the fan is turned on, the cold air can pass through the cooling package from front to back. During operation, the cold air at the upper part of the cooling package passes through the fuel radiator 3, the intercooler 1 and the upper part of the water-cooled radiator 2 in sequence, and the cold air at the lower part of the cooling package passes through the condenser 5, the oil-cooled radiator 4 and the lower part of the water-cooled radiator 2 in sequence. The high-temperature medium circulating inside each sub-radiator exchanges heat with the cold air, thereby cooling the high-temperature medium circulating inside.

[0039] When the front side of the sub-radiator needs to be maintained and cleaned: the water-cooled radiator 2 does not completely block the front side of the intercooler 1. At the same time, the water-cooled radiator 2 is small in size and easy to disassemble, so it can be directly disassembled. The condenser 5 can slide along the guide rail bracket to make room for maintenance operations on the front side of the oil-cooled radiator 4. Since the intercooler 1 and the oil-cooled radiator 4 are arranged vertically, no gap is required on the front side. There is only a gap on the front side of the water-cooled radiator 2. Therefore, within the same volume of the heat dissipation package, the gap on the front side of the water-cooled radiator 2 is increased, thereby increasing the maintenance operation space on the front side of the water-cooled radiator 2 (in the prior art, the sub-radiators are mostly arranged in multiple layers in front and back, so 3-4 gaps are required between the above five sub-radiators. Due to the layout space of the vehicle hood, each gap is small, so there is a lack of maintenance and repair space).

[0040] In summary, by adopting the utility model, the intercooler 1 and the oil-cooled radiator 4 are arranged vertically, and within the same volume of the heat dissipation package, the gap on the front side of the water-cooled radiator 2 is increased, thereby increasing the maintenance and operation space on the front side of the water-cooled radiator 2; at the same time, the condenser 5 can slide relative to the oil-cooled radiator 4 along the guide rail bracket, thereby being able to vacate the maintenance and operation space on the front side of the oil-cooled radiator 4 when maintenance is required; reducing the maintenance difficulty of each sub-radiator in the heat dissipation package; in addition, the windward area of ​​the water-cooled radiator 2 located at the rearmost side is increased, thereby ensuring the heat dissipation performance of the sub-radiator.

[0041] Furthermore, the sheet metal bracket includes a connecting bottom plate 7 and two connecting side plates 6, the two connecting side plates 6 are arranged opposite to each other, and the lower end of the connecting side plate 6 is in contact with the upper surface of the connecting bottom plate 7; the intercooler 1 and the oil cooling radiator 4 are both located between the two connecting side plates 6, the left and right sides of the intercooler 1 are both connected to the upper part of the connecting side plate 6, the left and right sides of the oil cooling radiator 4 are both connected to the lower part of the connecting side plate 6, the lower side of the oil cooling radiator 4 and the lower side of the water cooling radiator 2 are both connected to the connecting bottom plate 7, and the upper part of the water cooling radiator 2 is connected to the top of the connecting side plate 6.

[0042] The oil-cooled radiator 4 and the water-cooled radiator 2 are fixed by connecting the bottom plate 7, and the oil-cooled radiator 4 and the intercooler 1 are fixed by two connecting side plates 6, so as to form a frame structure, thereby improving the rigidity of the heat dissipation package; at the same time, the intercooler 1 and the fuel radiator 3 as a whole, the oil-cooled radiator 4 and the condenser 5 as a whole, and the water-cooled radiator 2 as a whole can be disassembled from the heat dissipation package respectively, so as to facilitate the individual replacement of damaged sub-heat dissipation modules.

[0043] Furthermore, a sealing plate 8 is provided on the outer side of the connecting side plate 6 , and both the left and right sides of the water-cooling radiator 2 are connected to the sealing plate 8 .

[0044] It is convenient to close the side of the gap on the front side of the water-cooled radiator 2 to prevent cold air from entering the front side of the water-cooled radiator 2 from the side, thereby ensuring the ventilation volume of the intercooler 1 and the oil-cooled radiator 4; at the same time, it prevents debris from entering the front side of the water-cooled radiator 2 from the side, thereby increasing the service life of the heat dissipation package.

[0045] Furthermore, the intercooler 1 is connected to the upper part of the connecting side plate 6 by screws; the oil-cooled radiator 4 is connected to the lower part of the connecting side plate 6 by screws; the oil-cooled radiator 4 and the water-cooled radiator 2 are both connected to the connecting bottom plate 7 by screws; the water-cooled radiator 2 is connected to the sealing plate 8 by screws.

[0050] The upper guide rail 10 and the lower guide rail 11 can adopt a downwardly opening chute structure, and the condenser 5 can be drawn out along the chute, which has a simple structure and is easy to install.

[0051] Furthermore, the upper guide rail 10 and the lower guide rail 11 are both arranged horizontally.

[0052] This avoids structural interference between the condenser 5 and the pipeline of the oil cooling radiator 4 when the condenser 5 slides.

[0053] Furthermore, an air guide cover 12 is provided on the rear side of the water-cooled radiator 2 , and the air guide cover 12 is sealedly connected to the left and right side walls of the water-cooled radiator 2 .
