[0002] The automotive condenser is a heat dissipation device in the automotive air conditioning system. It dissipates the heat generated by the refrigerant during the compressor compression process to the outside space of the vehicle, turning the high-temperature, high-pressure gas from the compressor into a medium-temperature, high-pressure liquid.

[0003] Currently, most condensers are fixed to the radiator or cooling fan by welding brackets onto the condenser's manifold or dryer and then using bolts or clips.

[0004] Specifically, currently, the condenser uses a stamped sheet metal bracket, which is assembled with the cooling fan. The sheet metal bracket is located on the side plate of the condenser, with both sides of the bracket arranged around the perimeter of the side plate, and nuts are spot-welded to one side of the bracket. Therefore, during vehicle assembly and tightening, this can easily cause deformation of the condenser side plate, flat tube, or fins, thus affecting the condenser's heat exchange efficiency.

[0040] The automotive condenser is a heat dissipation device in the automotive air conditioning system. It dissipates the heat generated by the refrigerant during the compressor compression process to the outside space of the vehicle, turning the high-temperature, high-pressure gas from the compressor into a medium-temperature, high-pressure liquid.

[0041] Currently, most condensers are fixed to the radiator or cooling fan by welding brackets onto the condenser's manifold or dryer and then using bolts or clips.

[0042] Specifically, the condenser uses a stamped sheet metal bracket, which is assembled with the cooling fan. The sheet metal bracket is located on the side plate of the condenser, with both sides of the bracket arranged around the perimeter of the side plate, and nuts are spot-welded to one side of the bracket. Therefore, during vehicle assembly and tightening, the condenser side plate, flat tube, or fins are prone to deformation, thus affecting the condenser's heat exchange efficiency.

[0043] This utility model proposes a vehicle condenser.

[0044] Please see Figures 1 to 4 In one embodiment of this utility model, the vehicle condenser 10 is connected to a cooling fan 20. It is understood that the function of the condenser is to cool and convert the high-temperature, high-pressure gaseous refrigerant discharged from the compressor into a liquid state. When the refrigerant releases heat in the condenser, without effective heat dissipation, the condenser temperature will rise, leading to a decrease in cooling efficiency and potentially damaging the equipment. The main function of the cooling fan 20 is to enhance the condenser's heat dissipation efficiency. It accelerates the flow of surrounding air through forced convection, thereby carrying away the heat released by the condenser and improving heat dissipation efficiency.

[0045] The automotive condenser 10 includes a condenser body 100, a protective plate 200, and a first connecting bracket 300. Specifically, the condenser body 100 includes two parallel and spaced-apart manifolds 110 and a heat dissipation section 120 disposed between the two manifolds 110. The heat dissipation section 120 includes a plurality of heat dissipation pipes 121 disposed between the two manifolds 110. The two ends of the heat dissipation pipes 121 are respectively connected to the two manifolds 110, and fins (not shown) are provided between adjacent heat dissipation pipes 121. It can be understood that the manifolds 110 extend along a first direction, and the heat dissipation pipes 121 extend along a second direction. In one embodiment, the first direction and the second direction are perpendicular. In one embodiment, the plurality of heat dissipation pipes 121 and the plurality of fins are respectively welded to the two manifolds 110. In one embodiment, the heat dissipation pipes 121 are configured as flat pipes; of course, in other embodiments, the heat dissipation pipes 121 can also be round pipes.

[0046] In one embodiment, two manifolds 110 are respectively connected to the vehicle body. Specifically, one end of the manifold 110 is provided with a first damping pad (not shown). At the position corresponding to this end of the manifold 110, a first bracket (not shown) is bolted to the vehicle body. The first bracket is provided with a first mounting groove (not shown). The first damping pad is inserted into the first mounting groove, thereby connecting one end of the manifold 110 to the vehicle body. The other end of the manifold 110 is provided with a second damping pad (not shown). At the position corresponding to this end of the manifold 110, a longitudinal beam (not shown) is provided with a mounting hole (not shown). The second damping pad is inserted into the mounting hole, thereby connecting the other end of the manifold 110 to the vehicle body. In this way, the connection between the two manifolds 110 and the vehicle body is realized, thereby realizing the connection between the vehicle condenser 10 and the vehicle body.

[0047] Understandably, in one embodiment, a manifold 110 is provided with an inlet connector 111 and an outlet connector 112 for introducing and drawing refrigerant into and out of the vehicle condenser 10, thereby realizing the flow of refrigerant in the vehicle condenser 10.

[0048] A protective plate 200 is provided at each of the opposite ends of the condenser body 100. The protective plate 200 has a groove 210 with its opening facing away from the condenser body 100.

[0049] Specifically, the extension direction of the protective plate 200 is consistent with the extension direction of the heat dissipation pipe 121. Along the first direction, a protective plate 200 is installed on each of the heat dissipation pipes 121 at both ends of the heat dissipation section 120; along the second direction, both ends of the protective plate 200 are connected to two manifolds 110 respectively. It is understood that the protective plate 200 provides structural support, connection, fixation, and protection for the condenser body 100. The protective plate 200 has a groove 210 with a slot. When connecting the protective plate 200 and the manifolds 110, the slot of the groove 210 is positioned away from the condenser body 100. Typically, the protective plate 200 is made of sheet metal, which helps to improve the supporting and protective force of the protective plate 200 on the condenser body 100. The protective plate 200 and the manifolds 110 can be fixed by welding. It is understood that the groove 210 is formed by a reinforcing flange during the pressurization process of the sheet metal part.

[0050] Please see Figure 5 and Figure 6 The first connecting frame 300 includes a support part 310 fixed to the guard plate 200 and a fixing part 320 provided on the support part 310. The support part 310 is also embedded in the groove 210 to support the two opposite groove walls of the groove 210. The fixing part 320 is connected to the cooling fan 20.

[0051] Understandably, the vehicle condenser 10 is provided with a first connecting bracket 300, which is connected to the cooling fan 20, thus realizing the connection between the vehicle condenser 10 and the cooling fan 20. Specifically, the first connecting bracket 300 includes a support portion 310 and a fixing portion 320. The support portion 310 is embedded in the groove 210 of the guard plate 200 to support the two opposite groove walls of the groove 210. Understandably, in one embodiment, the support portion 310 is configured as a support block, and the two opposite side walls of the support portion 310 contact the two opposite groove walls of the groove 210, thereby supporting the two opposite groove walls of the groove 210. Of course, there can also be a small gap between the two pairs of side walls of the support portion 310 and the two opposite groove walls of the groove 210, that is, the support portion 310 and the groove 210 are in clearance fit, thereby facilitating the embedding of the support portion 310 into the groove 210. It is worth noting that the gap is only a distance reserved for easy embedding. The gap should not be too large, otherwise it will affect the support of the support part 310 to the two walls of the groove 210. The specific value of the gap is not limited here.

[0052] The fixing part 320 is provided on the support part 310 and is used to connect with the cooling fan 20. It is understood that when connecting the vehicle condenser 10 and the cooling fan 20, the first connecting bracket 300 is embedded in the groove 210 of the protective plate 200, and then the vehicle condenser 10 and the radiator are connected through the fixing part 320. In this way, the support part 310 is embedded in the groove 210 to support the two opposing groove walls of the groove 210, resulting in a relatively large contact area between the first connecting bracket 300 and the two opposing groove walls of the groove 210 of the protective plate 200. When the vehicle condenser 10 and the cooling fan 20 are tightly assembled, deformation of the protective plate 200 or the condenser body 100 of the vehicle condenser 10 can be avoided, that is, deformation of the heat exchange pipe 121 and the fins can be avoided, thereby preventing damage to the heat exchange effect of the vehicle condenser 10.

[0053] Understandably, both skid plates 200 are equipped with first connecting brackets 300 to enhance the connection stability between the vehicle condenser 10 and the cooling fan 20. In one embodiment, the two first connecting brackets 300 are arranged approximately diagonally, which further improves the connection stability between the vehicle condenser 10 and the cooling fan 20.

[0054] Meanwhile, compared to integrating the first connecting frame 300 and the groove wall of the groove 210 of the guard plate 200 into one piece, in this utility model, the first connecting frame 300 and the guard plate 200 are set separately. This avoids the fastening force on the first connecting frame 300 being transmitted in the direction of the connection between the first connecting frame 300 and the guard plate 200 when fastening the vehicle condenser 10 and the cooling fan 20. This avoids the deformation of the guard plate 200 at the connection with the first connecting frame 300, thereby further avoiding the possibility of deformation of the guard plate 200, avoiding the impact on the heat exchange effect of the vehicle condenser 10, and ensuring the heat exchange efficiency of the vehicle air conditioner.

[0055] The technical solution of this utility model is to set a condenser body 100, a guard plate 200 and a first connecting frame 300 in the vehicle condenser 10. A guard plate 200 is provided at each of the opposite ends of the condenser body 100. The guard plate 200 has a groove 210 with the groove opening facing away from the condenser body 100. The first connecting frame 300 includes a support part 310 fixed to the guard plate 200 and a fixing part 320 provided to the support part 310. The support part 310 is also embedded in the groove 210 to support the opposite two groove walls of the groove 210. The fixing part 320 is connected to the cooling fan 20. Thus, by embedding a support part 310 inside the groove 210, the present invention enables the support part 310 to support the opposite side walls of the groove 210, thereby avoiding deformation of the guard plate 200 or the condenser body 100 when fastening the vehicle condenser 10 and the cooling fan 20, and thus avoiding the impact on the heat exchange effect of the vehicle condenser 10, thereby ensuring the heat exchange efficiency of the vehicle air conditioner and ensuring the comfort of vehicle use.

[0056] Please see Figures 5 to 7 In an embodiment of this utility model, the fixing part 320 is configured as an insert nut 321, and the groove wall of the groove body 210 is provided with a first clearance hole 211 corresponding to the insert nut 321. The first fastener (not shown) connected to the cooling fan 20 passes through the first clearance hole 211 to connect with the insert nut 321.

[0057] Specifically, in the solution shown in the figures of this utility model, the fixing part 320 is configured as an insert nut 321, which is fixed to the support part 310. It is understood that a receiving groove is formed in the support part 310, and the insert nut 321 is embedded in the receiving groove. The support part 310 also has a third clearance hole 311 communicating with the receiving groove, and the third clearance hole 311 corresponds to the insert nut 321. Simultaneously, the groove wall of the groove body 210 also has a first clearance hole 211 corresponding to the insert nut 321; that is, both opposite groove walls of the groove body 210 have first clearance holes 211. It is understood that the cooling fan 20 has a fourth clearance hole 21 at the position corresponding to the insert nut 321 (e.g., ...). Figure 3As shown, a first fastener passes through a first clearance hole 211, a third clearance hole 311, an insert nut 321, and a fourth clearance hole 21, thereby connecting the vehicle condenser 10 and the cooling fan 20 together. In one embodiment, the first fastener is configured as a bolt, screw, etc. Of course, in other embodiments, the fixing part 320 may also be a threaded hole or the like provided on the support part 310.

[0058] Please see Figure 5 and Figure 6 In an embodiment of the present invention, the first connecting frame 300 further includes a clamping part 330 disposed on one side of the support part 310. A clamping groove 331 is formed between the clamping part 330 and the support part 310. One groove wall of the groove body 210 is clamped in the clamping groove 331. The clamping part 330 is provided with a second clearance hole 332 corresponding to the first clearance hole 211.

[0059] Specifically, in the embodiment shown in the figures of this utility model, the first connecting frame 300 further includes a clamping part 330, which is disposed opposite to the supporting part 310, and a clamping groove 331 is formed between them. In one embodiment, the clamping part 330 and the supporting part 310 are connected and are integrally formed, which facilitates the processing and forming of the first connecting frame 300 and improves the processing efficiency of the first connecting frame 300. One wall of the groove 210 is clamped in the clamping groove 331, that is, the supporting part 310 is located inside the groove 210, and the clamping part 330 is located outside the groove wall of the groove 210. This arrangement improves the convenience of embedding the first connecting frame 300 into the groove 210 of the guard plate 200. In one embodiment, the opposite sides of one wall of the groove 210 are in contact with the supporting part 310 and the clamping part 330, respectively. Understandably, in order to connect the vehicle condenser 10 and the cooling fan 20 through the first connecting bracket 300, the clamping part 330 is provided with a second clearance hole 332 at the position corresponding to the first clearance hole 211, so that the first fastener can pass through.

[0060] In embodiments of this utility model, the support portion 310, the insert nut 321, and the clamping portion 330 are integrally injection molded. It is understood that, in one embodiment, the support portion 310 and the clamping portion 330 are configured as plastic parts, while the insert nut 321 is configured as a metal part. Using a metal part for the insert nut 321 improves its structural strength and service life. The support portion 310, the clamping portion 330, and the insert nut 321 are integrally molded using an insert injection molding process. This simplifies the molding process of the support portion 310, the insert nut 321, and the clamping portion 330, and improves the processing efficiency of the first connecting frame 300.

[0061] In embodiments of this invention, the insert nut 321 is configured as a polygonal structure. It is understood that, compared to a circular structure, the polygonal structure of the insert nut 321 makes it easier to position during the molding process, preventing displacement during injection molding. In the embodiment shown in the figures of this invention, the insert nut 321 is configured as a square; however, it can also be rectangular, hexagonal, etc. The specific shape of the insert nut 321 is not limited here.

[0062] Please see Figures 5 to 7 In an embodiment of this utility model, the groove 210 is provided with a first fixing hole 212 on the groove wall of the clamping groove 331, and the clamping part 330 is provided with a second fixing hole 333. The second fastener 340 passes through the first fixing hole 212 and the second fixing hole 333 to fix the guard plate 200 and the clamping part 330.

[0063] Specifically, in one embodiment, the groove wall of the groove 210, which is clamped within the clamping groove 331, is provided with a first fixing hole 212, and the clamping part 330 is provided with a second fixing hole 333. The first fixing hole 212 and the second fixing hole 333 serve a positioning function, allowing the second fastener 340 to pass through the first fixing hole 212 and the second fixing hole 333, thereby fixing the clamping part 330 to the guard plate 200. In this way, the connection between the clamping part 330 and the guard plate 200 is realized. At the same time, the clamping part 330 is connected to the support part 310, so that the support part 310 is indirectly fixed to the guard plate 200 through the clamping part 330. After the first connecting bracket 300 is installed onto the guard plate 200, the second fastener 340 is first passed through the first fixing hole 212 and the second fixing hole 333 to fix the clamping part 330 and the supporting part 310 onto the guard plate 200, thereby preventing misalignment of the first connecting bracket 300 and preventing movement of the first connecting bracket 300 during connection with the cooling fan 20. In one embodiment, the second fastener 340 is configured as a fixing pin. Of course, the second fastener 340 can also be a rivet, etc.

[0064] In one embodiment, two first fixing holes 212 are provided on opposite sides of the first clearance hole 211, and two second fixing holes 333 are provided on opposite sides of the second clearance hole 332. That is, the first clearance hole 211 is located between the two first fixing holes 212, and the second clearance hole 332 is located between the two second fixing holes 333. This further improves the connection stability between the clamping part 330 and the guard plate 200, thereby improving the connection stability between the support part 310 and the guard plate 200.

[0065] In one embodiment, the groove 210 of the guard plate 200 is provided with a first clearance hole 211 and a first fixing hole 212 on both opposite groove walls. This redundant arrangement allows the first clearance hole 211 and the first fixing hole 212 on either side of the guard plate 200 to be installed according to the installation space and other conditions, thereby improving the connection convenience between the vehicle condenser 10 and the cooling fan 20.

[0066] In one embodiment, the support portion 310 has a third fixing hole 312 at the position corresponding to the first fixing hole 212, so that the second fastener 340 passes through the second fixing hole 333 and the first fixing hole 212 in sequence, and then extends into the third fixing hole 312. The provision of the third fixing hole 312 further improves the connection reliability between the clamping portion 330 and the guard plate 200. In one embodiment, the third fixing hole 312 is a blind hole. Of course, in other embodiments, the third fixing hole 312 can also be a through hole, and the other side wall of the guard plate 200 is also provided with a first fixing hole 212. The second fastener 340 passes through the second fixing hole 333, one first fixing hole 212, the third fixing hole 312, and another first fixing hole 212, thereby realizing the connection between the clamping portion 330 and the guard plate 200.

[0067] In one embodiment, the clamping part 330 is provided with reinforcing ribs at the locations where the second fixing hole 333 and the second clearance hole 332 are provided, to enhance the structural strength of the clamping part 330. In another embodiment, the supporting part 310 is provided with reinforcing ribs at the locations where the third clearance hole 311 and / or the third fixing hole 312 are provided, to enhance the structural strength of the supporting part 310. The reinforcing ribs can be cylindrical, square, etc., and the shape and number of the reinforcing ribs are not limited here.

[0068] In one embodiment, a sealing element 220 is provided on the outer side of the groove wall of the groove 210 of the guard plate 200 near the cooling fan 20. This sealing element 220 is designed to fit snugly against the cooling fan 20 when the vehicle condenser 10 and the cooling fan 20 are connected, thereby preventing excessive air leakage through the gap between the vehicle condenser 10 and the cooling fan 20, and ensuring the cooling effect of the cooling fan 20 on the vehicle condenser 10. In one embodiment, the sealing element 220 can be a sponge, foam, etc., wherein the sponge or foam can be fixed to the guard plate 200 by adhesive.

[0069] Please see Figures 1 to 4 In an embodiment of this utility model, a second connecting bracket 400 is provided on the condenser body 100, and the second connecting bracket 400 is used to connect with the cooling fan 20.

[0070] Specifically, in one embodiment, the second connecting bracket 400 is configured as a snap-fit, and the cooling fan 20 is correspondingly provided with a snap-fit ​​structure 22. When the vehicle condenser 10 and the cooling fan 20 are connected, the second connecting bracket 400 is first snapped into the snap-fit ​​structure 22 on the cooling fan 20 to achieve pre-positioning of the vehicle condenser 10 and the cooling fan 20; then, the first connecting bracket 300 is used to fix the vehicle condenser 10 and the cooling fan 20 together. In this way, the setting of the second connecting bracket 400 achieves pre-positioning of the vehicle condenser 10 and the cooling fan 20, and also improves the connection stability of the vehicle condenser 10 and the cooling fan 20. In one embodiment, the snap-fit ​​structure 22 on the cooling fan 20 is made of plastic, and the second connecting bracket 400 is made of aluminum. The use of aluminum is beneficial to improving the connection reliability of the two. The specific structure of the second connecting bracket 400 is not limited here.

[0071] Please see Figure 1 , Figure 4 and Figure 8 In an embodiment of this utility model, the vehicle condenser 10 further includes a drying cylinder 500 installed on the condenser body 100. The opening of the drying cylinder 500 is provided with a plug structure 510, and a limiting structure 520 is provided inside the drying cylinder 500. The limiting structure 520 is used to restrict the plug structure 510 from coming out.

[0072] Understandably, the dryer cylinder 500 is typically used in conjunction with the condenser to keep the air conditioning system dry, filter impurities, store refrigerant, and ensure stable and efficient system operation. In the embodiment shown in the figures of this utility model, the dryer cylinder 500 is fixed to the manifold 110 by brazing and extends along a first direction. The dryer cylinder 500 includes a cylinder body, a plug structure 510, and a limiting structure 520, etc. The plug structure 510 is located at the opening of the cylinder body to prevent refrigerant from flowing out of the cylinder body. In one embodiment, the end of the plug structure 510 facing the cylinder body has a circular boss 511, which fits the cylinder body with a clearance. When the plug structure 510 is assembled into the cylinder body, the circular boss 511 acts as a guide and also serves as a first seal. The end of the plug structure 510 facing away from the cylinder body has an installation part 512 for installing the plug structure 510 into the cylinder body. In one embodiment, the mounting portion 512 is configured as a handheld boss located at one end of the plug structure 510. The plug structure 510 also has an annular groove 513 between the circular boss 511 and the mounting portion 512. The annular groove 513 is used for assembling a sealing ring, which contacts the inner wall of the cylinder to provide a second seal and prevent refrigerant leakage. In one embodiment, the plug structure 510 has multiple spaced annular grooves 513 for assembling multiple sealing rings to improve the sealing performance of the plug structure 510.

[0073] Understandably, to prevent the plug structure 510 from detaching from the cylinder, a limiting structure 520 is also provided inside the drying cylinder 500. In one embodiment, the limiting structure 520 is configured as a retaining spring 521. The outer periphery of the retaining spring 521 abuts against the inner peripheral wall of the cylinder, and one side of the retaining spring 521 abuts against the end of the plug structure 510 away from the cylinder. Understandably, the retaining spring 521 is configured as an open-loop structure. At this time, the retaining spring 521 is in a contracted state. Under the action of its own elastic force, the retaining spring 521 is locked with the inner sidewall of the cylinder, thereby preventing the plug structure 510 from detaching from the opening of the drying cylinder 500. Of course, in other embodiments, the limiting structure 520 may also include a silicone limiting ring disposed on the inner sidewall of the drying cylinder 500. When the plug structure 510 is installed, the silicone limiting ring is compressed and deformed under the installation force, so that the plug structure 510 can extend into the lower part of the silicone limiting ring and abut against the side wall of the silicone limiting ring facing the inside of the drying cylinder 500, thereby limiting the plug structure 510.

[0074] In this embodiment of the invention, the plug structure 510 is configured as a solid plastic part. It is understood that, compared to the prior art where the plug structure 510 uses aluminum, the plug structure 510 in this invention uses a plastic part, which helps reduce the cost of the automotive condenser 10 and also contributes to its lightweight design. Furthermore, since the plug structure 510 is made of plastic, its overall weight is lighter, eliminating the need for a hollow structure to reduce weight, thus simplifying the manufacturing process and improving production efficiency. Additionally, the solid plastic plug structure 510 also helps improve its structural strength.

[0075] This utility model also proposes a vehicle air conditioner, which includes a vehicle condenser 10. The specific structure of the vehicle condenser 10 is as described in the above embodiments. Since this vehicle air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
