[0002] The grooved aluminum used in heat exchangers is a specific-shaped aluminum alloy material, mainly used to improve the heat exchange efficiency. The design of grooved aluminum, also known as finned aluminum or fin aluminum, is usually to increase the surface area in contact with the fluid, thereby enhancing the heat transfer effect. It is very common in applications such as air conditioning systems, automotive radiators, and industrial cooling devices. Grooved aluminum can be produced by extrusion molding, so that fin structures with different shapes and sizes can be made to meet different usage requirements.

[0003] For example, the existing Chinese patent (CN204787998U) discloses grooved aluminum for heat exchangers. The grooved aluminum for heat exchangers includes: a grooved aluminum body with a "C" shape in a top view structure, and the inner side surface of the grooved aluminum body is an arc surface structure. A flange part is integrally formed at a position on the inner side surface of the grooved aluminum body close to the right-angle end of the outer side surface of the grooved aluminum body; the grooved aluminum for heat exchangers with this structure overcomes the problem that the grooved aluminum in the prior art needs to be welded with a flange additionally due to its simple structure, resulting in an increase in the production cost of the heat exchanger. Thus, the process step of welding the flange is omitted, saving the production cost of the heat exchanger. At the same time, since the grooved aluminum for heat exchangers is an integrally formed structure, the bonding degree and structural strength between the flange and the grooved aluminum are ensured, and further, the quality of the heat exchanger applying the grooved aluminum for heat exchangers is improved.

[0004] In the above technical solution, as well as in the prior art, most of the outer sides of the grooved aluminum for heat exchangers are in a "C" shape structure, and the inside is in a "C" shape. According to its structural characteristics, its structural pressure-bearing performance is poor, and it is extremely easy to deform under pressure, affecting the installation of the grooved aluminum and the normal use of the heat exchanger.

A top reinforcing strip is clamped on the first groove at the top, and a side reinforcing strip is clamped on the first groove at the side. A clamping groove is opened on one side of the side reinforcing strip, a pressure-bearing rod is arranged inside the clamping groove, a bottom rubber pad is arranged at the bottom end of the pressure-bearing rod, a fixing plate is arranged on the outer wall of the upper half of the pressure-bearing rod, and a middle rubber sleeve is arranged between the bottom of the fixing plate and the top of the side reinforcing strip. The top end of the pressure-bearing rod protrudes from the top surface of the top reinforcing strip.

[0007] Furthermore, a second groove cooperating with the first groove is formed at the bottom of the top reinforcement strip, and a second groove cooperating with the first groove is also formed on one side of the side reinforcement strip.

[0008] Furthermore, there are two top reinforcement bars, which are arranged in parallel.

[0011] Furthermore, a through hole is provided in the middle of the movable sleeve rod, and a clearance fit is formed between the through hole and the connecting rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model realizes that during the use of the trough aluminum, the top reinforcement strip is provided on the top of the trough aluminum plate and the side reinforcement strip is provided on the side of the trough aluminum plate, so that the trough aluminum plates can be connected together to form an overall pressure-bearing effect, thereby increasing the pressure-bearing performance of the heat exchanger trough aluminum;

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a grooved aluminum for a heat exchanger with good pressure-bearing performance, comprising: a grooved aluminum body 1 and a grooved aluminum plate 2, the outer wall of the grooved aluminum body 1 is fixed with a grooved aluminum plate 2, first grooves 3 are opened on both sides of the top of the grooved aluminum plate 2, and first grooves 3 are also opened in the middle of both sides of the grooved aluminum plate 2, a top reinforcing strip 4 is clamped on the first groove 3 at the top, and a side reinforcing strip 6 is clamped on the first groove 3 at the side. During the use of the grooved aluminum, by arranging the top reinforcing strip 4 on the top of the grooved aluminum plate 2 and arranging the side reinforcing strip 6 on the side of the grooved aluminum plate 2, the grooved aluminum plates 2 can be connected together to form an overall pressure-bearing effect, thereby increasing the pressure-bearing performance of the grooved aluminum of the heat exchanger.

[0023] A snap-in slot 7 is defined on one side of the side reinforcement strip 6. A pressure rod 9 is positioned within this slot 7, with a bottom rubber pad 8 positioned at the bottom end. A fixing plate 11 is secured to the outer wall of the upper half of the pressure rod 9. A middle rubber sleeve 10 is positioned between the bottom of the fixing plate 11 and the top of the side reinforcement strip 6. The top end of the pressure rod 9 protrudes above the top surface of the top reinforcement strip 4. Bottom flanges 15 are located on both sides of the bottom of the trough body 1, with the bottom rubber pad 8 abutting against them. A portion of the force is transferred through the pressure rod 9 to the side reinforcement strip 6 and bottom flange 15, further reducing the stress on the trough aluminum plate 2 itself and improving its pressure-bearing performance. The bottom rubber pad 8 and middle rubber sleeve 10 act as a buffer.

[0024] A second groove 5 matching the first groove 3 is formed at the bottom of the top reinforcing strip 4 , and a second groove 5 matching the first groove 3 is also formed on one side of the side reinforcing strip 6 .

[0025] There are two top reinforcing bars 4, arranged in parallel. A connecting rod 12 is located between the two top reinforcing bars 4. A movable sleeve 13 is located outside the connecting rod 12. There are two movable sleeves 13, and an elastic connecting bar 14 is located between the two movable sleeves 13. The top of the elastic connecting bar 14 protrudes from the top surface of the top reinforcing bars 4. This allows objects applying pressure to first contact the elastic connecting bar 14 or the top of the pressure rod 9 when pressure is applied to the top of the aluminum channel, avoiding direct pressure on the aluminum channel.

[0026] A through hole is formed in the middle of the movable sleeve rod 13, and a clearance fit is formed between the through hole and the connecting rod 12. When the top of the channel aluminum is squeezed, part of the pressure is first transferred to the connecting rod 12 through the elastic connecting strip 14. The connecting rod 12 then transmits the force to the top reinforcing strip 4 to prevent the channel aluminum plate 2 from being deformed by the force. When the elastic connecting strip 14 is subjected to force, it will elastically deform, causing the movable sleeve plates 13 to move away from each other, thereby buffering the applied force.

[0027] During the use of the grooved aluminum, by setting a top reinforcement bar 4 on the top of the grooved aluminum plate 2 and a side reinforcement bar 6 on the side of the grooved aluminum plate 2, the grooved aluminum plates 2 can be connected together to form an overall pressure-bearing effect, thereby increasing the pressure-bearing performance of the grooved aluminum of the heat exchanger;

[0028] In addition, when the top of the channel aluminum is squeezed, part of the pressure is first transferred to the connecting rod 12 through the elastic connecting strip 14, and the force is transferred to the top reinforcing strip 4 through the connecting rod 12 to prevent the channel aluminum plate 2 from being deformed by the force. Another part of the force is transferred to the side reinforcing strip 6 and the bottom flange edge 15 through the pressure-bearing rod 9, further reducing the force on the channel aluminum plate 2 itself, improving the pressure-bearing performance of the channel aluminum, and preventing the deformation of the channel aluminum from affecting the heat exchange effect.

[0029] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
