Description

Technical Field

[0001] The utility model belongs to the technical field of automobile condensers, and more specifically relates to a simple-to-install automobile condenser core assembly. Background Art

[0002] In a refrigeration system, the evaporator, condenser, compressor and throttle valve are the four essential parts of the refrigeration system. The refrigeration principle of a general condenser is to suck the lower-pressure working fluid vapor from the evaporator into the compressor, and then compress the lower-pressure vapor of the compressor into higher-pressure vapor, so that the volume of the vapor decreases and the pressure increases. After the pressure is increased, it is sent to the condenser, condensed into a higher-pressure liquid in the condenser, and after throttling by the throttle valve, it becomes a lower-pressure liquid and is then sent to the evaporator, where it absorbs heat and evaporates to become a lower-pressure vapor, thereby achieving the purpose of the refrigeration cycle.

[0003] After the existing condenser core assembly is assembled, a fixed block is used to dock with the automobile mounting component, and then assembly holes are processed on the block, and the detachable installation is completed by fixing bolts. Since the condenser core assembly itself is heavy, this installation method has high labor intensity, inconvenient installation and disassembly, low installation efficiency and high cost.

[0004] After searching, the Chinese patent application number is: 202022492141.3, the application date is: November 2, 2020, and the name of the invention is: An easily disassembled and maintained automotive air conditioning condenser. This application is replaced by setting a complete mounting strip, and strip-shaped mounting grooves are provided on both sides of the mounting strip. When installing, first place the condenser in the specified position, and ensure that the two strip-shaped mounting grooves are respectively opposite to the mounting parts of the car, and then complete the installation of the entire condenser through the bolt structure. This application can improve the docking efficiency to a certain extent and reduce some labor intensity in the installation of the condenser by setting a strip-shaped mounting groove, but it still needs to use a bolt structure to fix the entire condenser, and the installation efficiency is low.

[0040] Example 1

[0041] like Figure 1 As shown, a simple-to-install vehicle condenser core assembly of this embodiment includes a header 1, which is symmetrically arranged on both sides of the condenser core assembly. A plurality of equally spaced microchannel flat tubes are inserted on the header 1, which are arranged parallel to each other, and both ends of each microchannel flat tube are respectively connected to the header 1 corresponding to the end thereof, and the headers 1 on both sides are connected through the microchannel flat tubes. A partition 7 is arranged inside the header 1, which is embedded in the pipe groove of the header 1 to adjust the distribution flow of the core process.

[0042] The condenser core assembly is also provided with fins, which are installed between any two microchannel flat tubes. Side plates 5 are provided on the outer edges of the first row of fins and the last row of fins, and the side plates 5 are processed into a plate flanging stamping structure. The side plates 5 of this structure are arranged to strengthen the overall structural support stability and protect the fins to avoid wear on the fins during assembly or use.

[0043] The condenser core assembly of this embodiment also includes an inlet pressure plate 6 and an outlet pressure plate 3, wherein the inlet pressure plate 6 is arranged on the manifold 1 on the side where the integrated subcooling tube cylinder 8 is located, and the outlet pressure plate 3 is arranged on the manifold 1 on the other side, and the inlet pressure plate 6 is connected with the manifold 1 to form a refrigerant inlet channel. The manifold 1 is connected with the outlet pressure plate 3 through the liquid outlet pipe 4 to form a refrigerant outflow channel. The refrigerant flows in from the inlet pressure plate 6, enters the manifold 1 and the microchannel flat tube, is diverted under the action of the partition 7, and finally flows into the outlet pressure plate 3 from the liquid outlet pipe 4 to form a smooth flow channel for the refrigerant to flow out.

[0044] More optimally, an integrated subcooling tube barrel 10 is also installed on one side of the collecting pipe 1 of the condenser core assembly of this embodiment. The integrated subcooling tube barrel 10 is connected to the collecting pipe 1. The setting of the integrated subcooling tube barrel 10 not only reduces the internal flow resistance of the condenser and increases the heat exchange capacity of the condenser, but can also be used to install the entire condenser core assembly in the cooling circulation system of the whole vehicle.

[0045] like Figure 1 As shown, the integrated subcooling tube body 8 is welded to one side of the header 1, and also includes a mounting bracket 2. The mounting bracket 2 is arranged on the integrated subcooling tube body 8 and on the other side of the header 1 where the integrated subcooling tube body 8 is not installed.

[0046] like Figure 1-3 As shown, one end of the mounting bracket 2 is connected to the header 1 or the integrated subcooling tube body 8, and the other end is provided with a slot 204. A side wall of the slot 204 is connected to a pressure plate 202 through a compression spring 203. A slot 201 is processed on the other side wall of the slot 204 away from the compression spring 203. When installing the condenser core assembly, the end of the latch is inserted into the slot 201, and the pressure plate 202 is used to press the latch. Using the compression spring 203 to press the pressure plate 202 can press the latch into the slot 204 in real time, improving the firmness of the installation. When disassembly is required, the latch can be disassembled by squeezing the compression spring 203, and the installation and disassembly are convenient.

[0047] The mounting bracket design of this embodiment adopts a mounting bracket without screw holes. Compared with the traditional mounting structure, it does not require manual screwing for installation, and the installation and disassembly are simpler, which solves the problems of difficult and cumbersome installation, effectively saves material and labor costs, reduces assembly quality risks, and improves fault tolerance. The above reasonable spatial layout structure facilitates the connection of the condenser core assembly with the cooling circulation system of the whole vehicle, and the disassembly and installation are simpler.

[0048] Example 2

[0049] like Figure 2 and Figure 3 As shown, the present embodiment is a simple-to-install vehicle condenser core assembly, and its structure is basically the same as that of Embodiment 1. The difference between the present embodiment and Embodiment 1 is that a protruding latch 205 is also processed on the slot 201, and the latch 205 cooperates with the bayonet at the end of the pin. The pin is inserted into the slot 204, and the end is snapped into the slot 201 to complete the snap connection. In order to further improve the firmness of the installation, the latch 205 is provided to perform secondary fixation with the pin, which effectively improves the firmness of the assembly.

[0050] In addition, as another implementation scheme of this embodiment, Figure 1As shown, there are four mounting brackets 2, which are respectively arranged at the four corners of the condenser core assembly, that is, a mounting bracket 2 is respectively installed at the upper and lower ends of the collecting tube 1 or the integrated subcooling tube barrel 8, and the mounting brackets 2 arranged on the collecting tube 1 are symmetrical with the mounting brackets 2 arranged on the integrated subcooling tube barrel 8, thereby improving the stability of the entire vehicle condenser core assembly installed on the vehicle body.

[0051] In addition, in order to improve the firmness and convenience of installation, the installation bracket 2 can be directly connected to the collecting pipe 1 or the integrated supercooling tube barrel 8 by welding.

[0052] Example 3

[0053] The structure of the vehicle condenser core assembly of this embodiment is basically the same as that of the embodiment 2, and the difference between the embodiment 2 and the embodiment 2 is that:

[0054] like Figure 3 As shown, one side of the pressure plate 202 is installed on the side wall of the slot 204 through at least two symmetrically distributed compression springs 203, which improves the firmness and stability of the connection compared to the connection of a single compression spring 203. At the same time, it is also convenient to improve the uniformity of force after connection, and the pressure plate 202 can be evenly pressed against the latch, so that the latch and the slot 204 can be stably connected.

[0055] like Figure 2 As shown, one end of the pressure plate 202 slightly extends out of the slot 204 to guide the insertion of the latch, and the width of the pressure plate 202 is greater than 1 / 2 of the width of the slot 204. This design not only ensures the clamping effect on the latch, but also leaves an assembly gap for the positioning of the latch, which is convenient for assembly.

[0056] In addition, when the condenser core assembly is not installed, the distance between the side of the pressure plate 202 away from the compression spring 203 and the side wall of the slot 204 away from the compression spring 203 is less than 1 / 2 of the thickness of the pin. This structural design can further improve the tightening effect of the pressure plate 202 on the pin.

[0057] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
