Abstract

The utility model relates to a water cooling strong draught cover of an internal combustion engine, which belongs to an internal combustion engine cooling device. The utility model is composed of an axial flow air duct and a flow guide cover, the axial flow air duct is fixed on the engine body of the internal combustion engine by a bracket, the rear end of the axial flow air duct is sheathed on a fan in a contactless mode, the front end of the axial flow air duct is connected with the flow guide cover in a sealing way, and the flow guide cover is in shape of a rectangle wire box and is arranged on a heat radiator by an auricle of the heat radiator. The utility model makes the inner part of the wind guide cover between the fan and the heat radiator form the certain vacuum degree, so the utility model largely increases the cooling air passing through the heat radiator. At the same time, the utility model avoids hot air backflow of the feather end of the fan. The utility model has the advantages of simple structure and easy installation, and can be arranged on various automobile engines.

Description

Water cooling strong draugh cover of internal-combustion engine

The utility model relates to the powerful blower cover of a kind of water-cooled engine, belongs to the internal-combustion engine cooling unit.

Existing internal-combustion engine fan guard is mounted on the radiator, it is shaped as preceding square hole, the taper type cover in Hou Yuan hole, fan is positioned at the Hou Yuan Kong Chu of fan guard, to blow to the rear by the air of heating behind the radiator, the swing during owing to internal-combustion engine and fan work, fan guard is had to away from fan, thereby caused the hot air reflux of fan plumage end, influenced the radiating effect of radiator.Chinese patent 90204945.5 discloses a kind of " additional cooler ", it is to increase an additional cooler in existing internal-combustion engine constituent, it is serially connected in original constituent, to increase heat dissipating capacity, though this method can be distributed some heats more, there are two problems: the one, be difficult to find suitable place to install on the vehicle; The 2nd, additional cooler is the flat box of a no accessory pinna, and its heat dissipation potential is very limited, at the high adstante febre of internal-combustion engine, still can't resolve the internal-combustion engine high temperature problem.

The purpose of this utility model is in order to overcome above-mentioned deficiency of the prior art, and a kind of good heat dissipation effect is provided, and is simple in structure, the powerful blower cover of water-cooled engine easy for installation.

The purpose of this utility model is achieved in that it is existed by axial flow air duct and drainage hood two-part structure.The axial flow air duct is fixed on the internal combustion engine body by support, and the contactless property in its rear end is sleeved on the fan, and front end and drainage hood are tightly connected, and drainage hood is rectangle box-like, and it is fixed on the radiator by the auricle of radiator.The axial flow air duct is axially and radially all fan is included in the air duct, therefore, internal-combustion engine is when work, and axial flow air duct between fan and the radiator and drainage hood inside form certain degree of vacuum, so increased cold blast rate, also avoided the hot air reflux of fan plumage end simultaneously by radiator.

The utility model compared with prior art has the following advantages:

1, improved the heat sinking function of radiator significantly.Through the homemade motor of 492Q is tested on test bay, when 30 ℃ of temperature, this motor middling speed on stand is moved (continuously) 4 hours, water temperature progressively heats up from cold water, and ascensional range constantly reduces, and drives after 30 minutes, water temperature remains on 65 ℃ and no longer rises, can give and seeing, be installed in when the utility model on the vehicle that travels, the motor car engine temperature is further reduced.

2, simple in structure, easy for installation.The utility model can replace former fan guard, is installed on the motor car engine of any model, and easy accessibility, is easy to repair.

The explanation of accompanying drawing drawing:

Accompanying drawing is a mounting structure schematic representation of the present utility model.

Embodiment describes the utility model in detail below in conjunction with (accompanying drawing):

The utility model is made of axial flow air duct (3), shrouding (8), stuffing box packing (7), drainage hood (6).Axial flow air duct (3) is fixed on the internal combustion (IC) engine airframe (1) by support (2), its rear end is contactless to be sleeved on the fan (9), its front end is welded with shrouding (8), this shrouding (8) is tightly connected by stuffing box packing (7) and drainage hood (6), and stuffing box packing (7) is to stick to foamed plastics on the shrouding or the rubber weather strip that is connected with shrouding.Drainage hood (6) line that is rectangle is box-like, and the small square hole of its rear end matches with axial flow air duct (3), and the big square opening of its front end matches with radiator (4), and drainage hood (6) is installed on the radiator (4) by the auricle (5) on the radiator (4).
