Description

Coupling unit of fan shroud assembly and heat exchanger}

The present invention relates to a coupling structure of heat exchangers and a fan shroud assembly, and more particularly, to a radiator, a condenser and a fan shroud assembly, an assembly of a fan shroud and a heat exchanger having an improved coupling structure of a radiator and a fan shroud. It relates to a bonding unit of.

Typically, there is a radiator for dissipating heat from the cooling water cooling the engine of the automobile, and an evaporator, a condenser and the like used in the air conditioner. In the air conditioner, the evaporator is mounted inside the case of the air conditioner, and the radiator and the condenser are mounted in the engine room of the vehicle.

Heat exchangers, that is, radiators and condensers, which are mounted in the engine room, are installed on the side adjacent to the grill of the vehicle engine room in order to narrow the installation space and improve heat exchange efficiency. The combination of heat exchangers and fan shrouds is roughly divided into a push fan type for placing a fan in front of the condenser and a fuller fan type for arranging a fan in the rear of the radiator according to a lay-out.

An example of a fuller fan type of the coupling structure of these heat exchangers is shown in FIG. 1. As illustrated, the fan shroud assembly 12 is installed at one side of the radiator 11, and the condenser 13 is installed at the other side of the radiator 11. In this structure, the combination of the radiator 11 and the fan shroud assembly 12 is formed with brackets for fixing them to the upper and lower tanks of the radiator 11 and the upper and lower portions of the corresponding shrouds, and they are provided with bolts and nuts. Is coupled by a coupling member. For example, the combination of the radiator 11 and the fan shroud assembly is formed with a fixing bracket into which a fixing member (eg, a square nut) is inserted into the tank outer circumferential surface of the radiator 11, and a support bracket on the fan shroud corresponding thereto. Is formed is made by screwing the square bracket of the support bracket and the fixing bracket by a set screw.

However, as described above, the coupling between the radiator 11 and the fan shroud assembly needs to be fixed using a coupling member such as a separate bolt and nut, so that the coupling structure is complicated and requires a lot of work time.

In particular, in the case of the push fan type in which the condenser is installed between the radiator and the fan shroud assembly according to the package and miniaturization of the fan shroud assembly and the heat exchanger, it is difficult to assemble with the coupling structure as described above. In other words, when a condenser is installed between the fan shroud assembly and the radiator, the bracket of the radiator for coupling the fan shroud assembly is relatively long and often broken. That is, the moment is received by the fan shroud coupled to the bracket end extending from the radiator there is a problem that is easily damaged by the vibration of the car and the fan.

The present invention is to solve the above problems, to provide a coupling unit of the fan shroud assembly and heat exchanger with improved assembly of the fan shroud assembly and the radiator in a state in which the condenser is installed between the radiator and the fan shroud assembly. There is this.

In order to achieve the above object, the coupling unit of the fan shroud assembly and the heat exchanger of the present invention includes a radiator for cooling the cooling water of the engine and a fan shroud for condensing the refrigerant of the air conditioner and the air to the radiator and the condenser side. The wood assembly is coupled sequentially, the first brackets extending from the lower tank of the radiator and provided with first and second coupling portions, respectively, and from the bottom of the fan shroud to the first brackets with the condenser interposed therebetween. It is characterized in that it comprises a coupling means including a second bracket extending and having a first and second protrusions coupled with the first and second coupling parts.

In the present invention, the first coupling portion is a circular or polygonal through hole formed in the first bracket so that the first protrusion is inserted, and the second coupling portion is pulled in from the end of the first bracket so as to be coupled to the second protrusion portion. It is formed. Preferably, the distance between the first coupling portion and the second coupling portion of the first bracket is equal to the distance between the first and second protrusions of the second bracket.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 show an example of the fan shroud assembly and heat exchanger coupling unit 20 according to the present invention.

Referring to the drawings, the coupling unit 20 of the fan shroud assembly and the heat exchanger is a fan shroud assembly formed by combining the radiator 21 and the fan 22a and the shroud 22b for cooling the engine coolant ( 22 is coupled by the first and second coupling means 30 and 40, and a condenser 23 is installed therebetween.

The first coupling means 30 for coupling the radiator 21 and the fan shroud assembly 22 with the condenser interposed therebetween is the first bracket 31 and the shira extending from the lower tank 21a of the radiator 21. The second bracket 32 extends from the bottom of the wood 22a and engages with the first bracket 31.

The first and second brackets 31 and 32 are coupled to each other by a first coupling part 33 formed of a through hole of a circular or polygonal shape in the first bracket 31 and an end from the end of the first bracket 31. The second coupling part 34 is formed, and the first and second protrusions 35 and 36 are formed on the lower surface of the second bracket 32 to form the first and second coupling parts 33 and 34. And the first and second protrusions 35 and 36 are coupled to each other. 3 and 4, the distance L1 between the first coupling part 33 and the second coupling part 34 of the first bracket 31 is determined by the second bracket 32. It is preferable to form the same distance (L2) between the one, two projections (35, 36). The coupling of the first and second brackets 31 and 32 is not limited to the above-described embodiment, and any structure may be used to bond the first and second brackets 31 and 32 to each other without a separate coupling member. It is possible.

The second coupling means 40 is for coupling the upper end portion of the upper tank 21b and the shroud 22a of the radiator 21, the third bracket 41 extending from the upper tank 21b, The fourth bracket 42 is installed on the top of the shroud 22b and the buffer member 42a is fixed, and the fixing member 43 for screwing the buffer member 42a and the third bracket 41 together.

The first and second protrusions 35 and 36 of the formed second bracket 32 are coupled to each other so that the lower portion of the fan shroud assembly 22 is supported by the lower tank 21a of the radiator 21. At this time, since the distance L1 between the first and second coupling parts 33 and 34 is the same as the distance L2 between the first and second protrusions 35 and 36, the second coupling part 34 is Even if it is open, it does not move or shake in the front, rear, left, and right directions. In particular, since the end of the first bracket 31 is formed by retracting the second coupling part 34, the coupling of the first and second brackets 31 and 32 is easy.

In this state, the fan shroud assembly 22 is coupled to the upper tank 21 b of the radiator 21 using the second coupling means to fix the fan shroud assembly to the radiator.

As described above, the coupling unit of the fan shroud assembly and the heat exchanger is coupled to the first and second brackets by the lower coupling of the fan shroud assembly and the radiator with the condenser interposed therebetween so that the coupling is easy and the operation according to the coupling Since man-hours can be greatly reduced, productivity can be improved.
