Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a side frame with a bracket in a heat exchanger such as a condenser for a car air conditioner.

BACKGROUND OF THE INVENTION In a car air conditioner capacitor, a plurality of brackets are fixed to a side frame for attaching the capacitor to the car body. Hat-shaped brackets are well known as such brackets. In the past, a downward protrusion was formed on one of the two wings of the hat-shaped bracket for simply positioning, and when this protrusion was fitted into a hole formed in the side frame, Both wings were welded to the side frames.

Problems that the invention aims to solve As mentioned above, in conventional capacitors,
Since both wing parts of the hat-shaped bracket are welded to the side frame, there is a problem in that the installation work is troublesome.

The object of this invention is to provide a side frame with a bracket for a heat exchanger that allows the attachment of the hat-shaped bracket to the side frame to be easily performed and is convenient for fixing piping.

Means for Solving the Problems In order to achieve the above object, the side frame with a bracket in the heat exchanger of this invention has a structure in which one of the two wing parts of the hat-shaped bracket is engaged with the side frame. The other wing is welded to the side frame, and bolt insertion holes are drilled in the top wall of the hat-shaped bracket, and nuts are secured so that the bolt insertion holes and screw holes are continuous on the inner surface of the top wall. A groove for fitting pipes is formed in a transverse shape on the top wall.

Function In the side frame with brackets in the heat exchanger of this invention, one of the two wing parts of the hat-shaped bracket is locked to the side frame, and the other wing part is welded to the side frame. Therefore, only one wing needs to be welded to the side frame.

Further, a bolt insertion hole is drilled in the top wall of the hat-shaped bracket, and a nut is fixed to the inner surface of the top wall so that the bolt insertion hole and the screw hole are continuous.
Since a groove for fitting the pipe is formed in a transverse shape on the top wall, a bolt is inserted into the hole drilled at one end of the pipe fixing piece having a groove symmetrical to this groove, and the bolt is inserted into the top wall. It can be tightened by screwing it into the nut through the insertion hole.

Embodiment FIG. 1 shows a capacitor for a car air conditioner. The capacitor includes a capacitor body 3 consisting of a meandering flat tube 1 having a refrigerant passage therein, and corrugated fins 2 interposed between the straight tube portions of the flat tube 1, and a capacitor body 3 which is fitted on both sides of the capacitor body 3. A pair of riveted channel-shaped side frames 4 and 5 are provided. Both ends of the flat tube 1 are connected to a refrigerant inflow pipe connection member 6. A refrigerant outflow pipe 7 is drawn out from the middle of the flat pipe 1, and at the tip of this pipe 7,
A pipe connecting member 9 for connecting a refrigerant outflow pipe (indicated by a chain line 8) is attached.

In this capacitor, brackets 10 and 20, which are hat-shaped when viewed from the lateral direction, are attached to the lower front surface of the left side frame 4 and to the lower center of the front height of the right side frame 5, respectively.

Figures 2 and 3 show the hat-shaped bracket 1 attached to the left side frame 4.
0 details are shown. This bracket 10 is
A rectangular top wall 11 that is approximately vertically rectangular when viewed from the front and parallel to the front surface of the side frame 4; a pair of upper and lower legs 12 that protrudes from the upper and lower ends of the top wall 11 toward the front surface of the side frame 4; 13, an upper wing portion 14 projecting upward from the tip of the upper leg portion 12, and a lower wing portion 15 projecting downward from the tip of the lower leg portion 13.

A bolt insertion hole 16 is formed in the top wall 11,
A capacitor mounting bolt screw-fitting nut 17 is fixed to the inner surface of the top wall 11 so that the screw hole is continuous with the bolt insertion hole 16. The lower wing portion 15 includes a wide portion 15a near the base and a narrow portion 15b on the distal end side of the wide portion 15a.

At the lower part of the front surface of the side plate 4, a wing locking portion 18 is formed in a cut-and-raised shape when viewed from the vertical direction. The narrow portion 15b of the lower wing portion 15 of the bracket 10 is connected to the side plate 4.
It is inserted between the upper surface and the locking part 18 and is locked to the side plate 4, and is fixed to the side plate 4 by spot welding the upper wing part 14 to the side plate 4.

4 and 5 show the hat-shaped bracket 2 attached to the right side frame 5.
0 details are shown. This bracket 20 is
A top wall 21 consisting of a vertically long rectangular portion 21a and a right protruding portion 21b, a pair of upper and lower leg portions 22, 23 protruding from both upper and lower ends of the vertically long rectangular portion 21a of the top wall 21 toward the side frame 5, and an upper side. It consists of an upper wing part 24 that protrudes upward from the tip of the leg part 22, and a lower wing part 25 that protrudes downward from the tip of the lower leg part 23.

Bolt insertion holes 26 and 27 are formed in the upper part of the vertically long rectangular part 21a of the top wall 21 and in the right protrusion part 21b, respectively. A nut 28 is fixed to the upper inner surface of the vertically long rectangular portion 21a so that the screw hole is continuous with the hole 26. A nut 2 is installed on the inner surface of the right protrusion 21b so that the screw hole is continuous with the hole 27.
9 is fixed. A pipe fitting groove 30 having an arcuate cross section and extending in the left-right direction is formed in a transverse shape at the center of the length of the vertically long rectangular portion 21a. The lower wing portion 25 includes a wide portion 25a that protrudes downward from the lower end of the lower leg portion 23, a narrow connecting portion 25b that protrudes rearward from the tip of the wide portion 25a, and a narrow connecting portion 25a that protrudes downward from the lower end of the lower leg portion 23.
It consists of a narrow part 25c extending downward from the tip of 5b.

A bolt (not shown) for fixing the refrigerant outflow pipe 8 is screwed into the nut 28 of the vertically long rectangular portion 21a. That is, a bolt is inserted into a hole drilled at one end of a pipe fixing piece (not shown) having a groove symmetrical to the pipe fitting groove 30, and then screwed into the nut 28 through the insertion hole 26 of the top wall 21. The piping 8 is clamped and fixed between the groove 30 of the top wall 21 and the groove of the piping fixing piece. A capacitor mounting bolt (not shown) is screwed into the nut 29 of the right protrusion 21b.

A wing part insertion hole 32 whose length is slightly longer than the width of the narrow part 25c of the lower wing part 25 is formed in the lower front surface of the side frame 5. The lower wing portion 25 of the bracket 20 has its narrow portion 25c inserted into the wing insertion hole 3.
2, the upper surface of the narrow portion 25c is brought into contact with the lower surface of the side frame 5, and the lower surface of the wide portion 25a is brought into contact with the upper surface of the side frame 5, thereby being locked to the side frame 5. The upper wing portion 24 of the bracket 20 has a side
It is spot welded to plate 5. In other words,
The bracket 20 is attached to the side frame 5 by having the lower wing section 25 locked to the side frame 5 and the upper wing section 24 being welded to the side frame 5.

Effects of the invention According to the side frame with bracket in the heat exchanger of this invention, one of the two wing parts of the hat-shaped bracket is locked to the side frame, and the other wing part is locked to the side frame. Since the bracket is welded to the side frame, only one wing portion needs to be welded to the side frame, which simplifies the attachment of the bracket to the side frame.

In addition, insert a bolt into a hole drilled at one end of a pipe fixing piece that has a groove symmetrical to the groove for fitting the pipe formed in the top wall of the hat-shaped bracket, and then insert a nut from the insertion hole in the top wall. Since the pipe can be tightened by screwing into the groove, the pipe can be easily fixed by clamping the pipe between both grooves, which is convenient.
