[0055] Reference Figure 1 As shown, Figure 1 A stereoscopic diagram of a microchannel heat exchanger provided in an embodiment of the present application. The microchannel heat exchanger 100 includes a first header 101, a second header 102, microchannel flat tubes 103, fins 104, a liquid inlet pipe 105, and a liquid outlet pipe 106. A plurality of microchannel flat tubes 103 are provided, and the plurality of microchannel flat tubes 103 are arranged at intervals along the length extension direction of the first header 101 and the second header 102, and the two ends of the plurality of microchannel flat tubes 103 are respectively connected to the first header 101 and the second header 102. The liquid inlet pipe 105 is connected to the first header 101, the liquid outlet pipe 106 is connected to the second header 102, and the fins 104 are provided between two adjacent microchannel flat tubes 103.

[0056] Reference Figure 2a to Figure 2c As shown, Figure 2a to Figure 2c for Figure 1 Each microchannel flat tube 103 is provided with a plurality of channels 103a, the length of each channel 103a extends along the length extension direction of the microchannel flat tube 103, and passes through both end surfaces of the microchannel flat tube 103, and each channel 103a is arranged at intervals along the width extension direction of the microchannel flat tube 103 (X direction in the figure), and there is a spacer b between two adjacent channels 103a.

[0057] When the heat exchanger is working, the refrigerant flows in each channel, and the state changes while the heat is exchanged.

In other embodiments, the cross section of the flat tube is fan-shaped, the two side surfaces in the height direction are not parallel, and the sizes of the included channels are also different.

[0059] In the above-mentioned embodiments, the widths of the spacers can be the same or different. The structure and size of the flat tube channels and the spacers are designed according to the requirements of the refrigerant used in the heat exchanger and the requirements of the heat exchange performance.

[0060] Reference Figure 3 As shown, Figure 3 A flow chart of a heat exchanger processing method provided in an embodiment of the present application. The heat exchanger processing method includes:

[0061] S11, providing a plurality of microchannel flat tubes, and arranging the plurality of microchannel flat tubes at intervals along a first direction.

[0062] Among them, the microchannel flat tube includes multiple channels extending along its length direction, the two ends of each channel respectively penetrate the two end surfaces of the microchannel flat tube, and each channel is arranged along the width extension direction of the microchannel flat tube, and there is a spacing part between two adjacent channels in the width direction of the microchannel flat tube.

[0063] S12, the sampling component starts from the initial position and moves along the first direction to collect specific information of each microchannel flat tube in sequence, and transmits the specific information to the control component.

[0064] In some embodiments, the sampling component starts to move along the slide bar from an initial position, and the initial position can be the position of the first microchannel flat tube or the last microchannel flat tube on the slide bar corresponding to the arrangement direction of the microchannel flat tubes, or the position of the specially designated microchannel flat tube on the slide bar, which is not limited here. The sampling component moves along the arrangement direction of the microchannel flat tubes, and the arrangement direction of the microchannel flat tubes is the first direction, and sequentially collects specific information of an end face or peripheral surface in the length direction of one or more microchannel flat tubes (for example, image information of the end face or peripheral surface of the microchannel flat tube), and transmits the specific information to the control component. The specific information on the end face of the microchannel flat tube includes the width information of one or more specified channels, the width information of multiple specified channels and the arrangement order, and the specified channels include the first channel or the last channel in the width direction of the microchannel flat tube, or the first channel and the last channel in the width direction of the microchannel flat tube.

[0065] In some embodiments, collecting specific information of each microchannel flat tube includes one or more of the following methods:

[0066] The cross-sectional area information of one or more channels specified by the microchannel flat tube is collected, wherein the cross-sectional area information refers to the cross-sectional area size and shape of the channel.

[0067] The cross-sectional area information and arrangement order of multiple channels specified by the microchannel flat tube are collected, wherein the cross-sectional area information and arrangement order refer to the cross-sectional area size and the arrangement order of the cross-sectional area size.

[0068] The information of a spacer designated by the microchannel flat tube is collected, and the spacer is located between two designated channels, wherein the spacer information refers to the width of the spacer. The width direction of the spacer is parallel to the width direction of the microchannel flat tube and the width direction of the channel.

[0069] The information and arrangement order of multiple spacers specified by the microchannel flat tube are collected, wherein the information and arrangement order of the spacers refer to the width of the spacers and the arrangement order of the numerical values ​​of the width of the spacers.

[0070] Collect the height information of a channel specified by the microchannel flat tube, wherein the height information refers to the numerical value of the height (the height of the channel in the Y direction in the figure). The information in this application refers to all information including parameters and other information.

[0071] S13, the control component compares the specific information with the pre-stored information, and sends feedback information according to the comparison result.

[0072] Specifically, the control component compares the specific information with the pre-stored information, and if the specific information is different from the pre-stored information, for example, the cross-sectional area of ​​a certain designated channel detected is different from the cross-sectional area of ​​the pre-stored designated channel, the comparison result is fed back to the indication component. The pre-stored information includes the width information, cross-sectional area information, height information or spacing information of one or more designated channels, or the width information and arrangement order, cross-sectional area information and arrangement order, spacing information and arrangement order of multiple designated channels.

[0073] S14. The indication component gives indication information according to the feedback information sent by the control component.

[0074] S15. Adjust the position of the corresponding microchannel flat tube according to the instruction information.

[0075] Specifically, according to the feedback information, if the specific information of a certain microchannel flat tube collected is inconsistent with the pre-stored information, the sampling component stops at a specific position, such as the position of a microchannel flat tube that is installed incorrectly or upside down, and sends an indication message through the indication component, and the indication message indicates that the microchannel flat tube is installed incorrectly or upside down. Furthermore, the prompt information can be a prompt given through a light source or an alarm sound to adjust the position of the corresponding microchannel flat tube. After adjusting the position of the corresponding microchannel flat tube, the sampling component continues to move and collects the specific information of one or more microchannel flat tubes again until the information collection of all microchannel flat tubes and the adjustment of the incorrectly installed microchannel flat tubes are completed.

[0076] For example, if the sampling component collects the width of the first channel in the width direction of the microchannel flat tube as L, the control component compares the width L of the first channel with the pre-stored width L' of the first channel of the corresponding microchannel flat tube. If L = L', it means that the corresponding microchannel flat tube is installed correctly. If L≠L', it means that the corresponding microchannel flat tube is installed incorrectly. Alternatively, if the widths of the first channel to the third channel in the width direction of the microchannel flat tube are L1, L2, and L3, respectively, the control component compares the widths of the first channel to the third channel with the pre-stored widths L1', L2', and L3' of the first channel to the third channel of the corresponding microchannel flat tube. If L1 = L1', L2 = L2', and L3 = L3', it means that the corresponding microchannel flat tube is installed correctly, otherwise it is installed incorrectly.

[0077] Further, adjusting the position of the corresponding microchannel flat tube according to the indication information includes moving the microchannel flat tube along a second direction according to the indication information, wherein the second direction is perpendicular to or at an angle to the first direction.

[0078] In this embodiment, the indicating component moves synchronously with the sampling component. It can be understood that in other embodiments, the indicating component and the sampling component can also be provided separately, and the indicating component does not need to move synchronously with the sampling component.

[0079] Reference Figure 4 As shown, Figure 4 for Figure 3 A further specific flow chart of steps S12 to S15 in FIG. 1 , specifically, the above steps S12 to S15 further include:

[0080] S101, the sampling component starts and moves along a first direction.

[0081] S102, collecting specific information of each microchannel flat tube, and transmitting the specific information to the control component.

[0082] S103, the control component compares the specific information with the pre-stored information to determine whether the specific information is consistent with the pre-stored information. If the determination result is yes, proceed to step S104, if the determination result is no, proceed to step S106.

[0083] S104, the sampling component continues to move.

[0084] The sampling component continues to move and step S102 is repeated.

[0085] S105, the sampling component travel ends.

[0086] S106, the sampling component stops moving.

[0087] S107: The instruction component sends instruction information.

[0088] S108. Adjust the microchannel flat tube that is installed incorrectly or reversely.

[0089] After the incorrectly or reversely installed microchannel flat tube is adjusted, step S101 is repeated.

[0090] Based on the above embodiments, the present application also discloses another heat exchanger processing method. The difference between this embodiment and the above embodiments is that, in this embodiment, after the sampling component collects all the specific information of the microchannel flat tubes that need to be collected, the specific information is passed to the control component. The control component compares the collected specific information of all microchannel flat tubes with the pre-stored information, and gives feedback information based on the comparison result, so that the indication component sends indication information based on the feedback information given by the control component, and then adjusts all the microchannel flat tubes that are installed incorrectly or reversely according to the indication information.

[0091] In this embodiment, the processing method of the heat exchanger includes the steps of:

[0092] S201, the sampling component starts and moves along a first direction.

[0093] S202, collecting specific information of each microchannel flat tube in sequence, and transmitting the collected specific information of all microchannel flat tubes to the control component.

[0098] Specifically, the sampling component 3 can move back and forth along the arrangement direction of the microchannel flat tubes 103 to collect specific information of the circumferential surface or end face of the microchannel flat tubes 103, and transmit the specific information to the control component. After receiving the specific information transmitted by the sampling component 3, the control component compares the specific information with the preset information, and sends feedback information to the indication component based on the comparison result, so that the indication component sends indication information based on the feedback information transmitted by the control component, for example, indicating that the microchannel flat tube is installed incorrectly or upside down.
