[0007] In a first aspect, the present invention provides a condenser forming plate, including:

[0008] A plate body, on one surface of the plate body, a plurality of guide ribs are convexly provided and arranged at intervals along a second direction. Each guide rib extends along a first direction having an included angle with the second direction, and a flow guide channel is formed between adjacent guide ribs;

[0009] And an annular flange, the annular flange is hermetically connected to the plate body. All the plurality of guide ribs are located within the area surrounded by the annular flange, and at least one of the two ends of some of the plurality of guide ribs extends to fit with the annular flange, and at least one of the two ends of the remaining guide ribs has a spacing from the annular flange.

[0011] In an optional embodiment, the annular flange has a second side opposite to the first side, the ends of some of the plurality of guide ribs are in contact with the second side, and the ends of the remaining guide ribs have a spacing from the second side.

[0012] In an optional embodiment, the guide rib includes a plurality of sequentially connected guide segments, and the extending directions of any two adjacent guide segments have an included angle.

[0013] In an optional embodiment, the included angle between any adjacent diversion sections is 70°-120°.

[0014] In an optional embodiment, a plurality of gaps are arranged at intervals in the circumferential direction of the annular flange on the annular flange, and the height of the bottom wall of the gap is higher than the height of the diversion rib.

[0015] In a second aspect, the present invention provides a condenser, which includes:

[0016] A plurality of condenser forming plates of any one of the foregoing embodiments arranged in a stacked manner, and the plurality of stacked condenser forming plates jointly define first flow channel cavities and second flow channel cavities that are alternately arranged in the stacking direction; the plurality of first flow channel cavities are connected, and the plurality of second flow channel cavities are connected.

[0017] In an optional embodiment, the condenser further includes a partition plate, which is arranged between adjacent forming plates and is used to change the flow direction of the fluid.

[0019] In an optional embodiment, the condenser further includes a liquid storage tank, and the first refrigerant joint or the second refrigerant joint is connected to the liquid storage tank.

[0020] The beneficial effects of the embodiments of the present invention are:

[0021] To summarize, this embodiment provides a condenser forming plate, comprising a connected plate body and an annular flange, a guide rib provided on one surface of the plate body, a guide channel for fluid flow formed between two adjacent guide ribs, and at least one of the two end portions of some of the multiple guide ribs extends to fit the inner side wall of the annular flange, and at least one of the two end portions of the remaining guide ribs has a distance from the inner side wall of the annular flange. When the fluid flows in the guide channel, the guide channel extends along the extension direction of the guide rib. When the fluid flows to the position where the end of the guide rib abuts the inner wall of the annular flange, that is, when the fluid flows to the position where there is no gap between the end of the guide rib and the inner wall of the annular flange, the fluid cannot directly bypass the end surface where the guide rib is connected to the annular flange and flow to the next guide channel. The fluid needs to turn over the side of the guide rib in its height direction and then enter the next guide channel. In this way, the position where the guide rib abuts the annular flange forms a flow-blocking structure, which increases the path of the fluid flowing in the molding plate and prolongs the time the fluid flows in the molding plate, thereby improving the heat exchange efficiency.

[0022] At the same time, since the ends of some guide ribs are in contact with the annular flange, and the ends of the remaining guide ribs are spaced apart from the annular flange, the flow-blocking structure formed by the guide ribs and the annular flange is small, the flow resistance is small, the flow field is evenly distributed, the turbulence effect is good, and the heat exchange efficiency is high.

[0038] In the following embodiments, unless otherwise specified, the first direction is the direction of the ab arrow, and the second direction is the direction of the cd arrow.

[0039] Please refer to Figures 1 - 3 , this embodiment provides a condenser forming plate, which has a simple and reasonable structure. The formed flow channels not only have a good flow field turbulence effect, but also have a small flow resistance and a high heat exchange efficiency.

[0040] In this embodiment, the condenser forming plate includes:

[0041] A plate body 100, on one surface of the plate body 100, a plurality of flow guiding ribs 110 are convexly arranged at intervals along the second direction, each flow guiding rib 110 extends along a first direction having an included angle with the second direction, and a flow guiding channel 120 is formed between adjacent flow guiding ribs 110;

[0042] And an annular flange 200, the annular flange 200 is hermetically connected to the plate body 100, a plurality of flow guiding ribs 110 are all located in the area surrounded by the annular flange 200, and at least one of the two ends of some of the plurality of flow guiding ribs 110 extends to be in contact with the annular flange 200, and at least one of the two ends of the remaining flow guiding ribs 110 has a spacing from the annular flange 200.

[0043] In the condenser molded plate provided in this embodiment, adjacent guide ribs 110 jointly define a guide channel 120, that is, the guide channel 120 extends along the extension direction of the guide rib 110. When the fluid flows in the guide channel 120, when the fluid flows to the position where the end of the guide rib 110 abuts the inner side wall of the annular flange 200, that is, when the fluid flows to the position where there is no gap between the end of the guide rib 110 and the inner side wall of the annular flange 200, the fluid cannot directly bypass the end surface of the guide rib 110 connected to the annular flange 200 to flow to the next guide channel 120. The fluid needs to flow over the side surface of the guide rib 110 in its height direction before entering the next guide channel 120. In this way, the position where the guide rib 110 abuts the annular flange 200 forms a flow-blocking structure, which increases the path of the fluid flow in the molded plate and prolongs the time the fluid flows in the molded plate, thereby improving the heat exchange efficiency.

[0044] At the same time, since the ends of some guide ribs 110 are in contact with the annular flange 200, and the ends of the remaining guide ribs 110 are spaced apart from the annular flange 200, the flow-blocking structure formed by the guide ribs 110 and the annular flange 200 is small, the flow resistance is small, the flow field is evenly distributed, the flow disturbance effect is good, and the heat exchange efficiency is high.

[0045] In this embodiment, the plate body 100 is optionally a rectangular plate, and includes two opposite length sides and two opposite width sides, and the adjacent length sides and width sides are connected. Optionally, a chamfer is provided at the connection between the length sides and the width sides, and the chamfer can be a rounded corner.

[0046] At the same time, the plate body 100 is provided with four through holes, namely two first through holes 130 and two second through holes 140. The two first through holes 130 and the two second through holes 140 are arranged at intervals in the length direction of the plate body 100, and the first through holes 130 and the second through holes 140 are arranged at intervals in the width direction of the plate body 100. When assembling the condenser, multiple plate bodies 100 are stacked and arranged, and the latter plate body 100 is rotated 180 degrees and then stacked with the previous plate body 100. With this design, the first through holes 130 and the second through holes 140 are alternately arranged, and the alternating multiple first through holes 130 and multiple second through holes 140 are all connected to form a connecting hole. After the condenser molded plate is assembled, four connecting holes are formed, among which two connecting holes arranged at intervals in the length direction of the plate body 100 and located on the same side of the plate body 100 are respectively connected to the inlet joint and the outlet joint of the refrigerant, and the other two connecting holes are respectively connected to the inlet joint and the outlet joint of the coolant.

[0047] Furthermore, the plate body 100 is provided with a reinforcing rib 150, which is an arc-shaped strip and extends along the circumference of the first through hole 130. It should be noted that a reinforcing rib 150 is provided at each location of the two first through holes 130.

[0048] Further, there are two bosses 160 provided on the plate body 100, and each boss 160 is provided with a second through hole 140. When laminating the condenser forming plates, two adjacent plate bodies 100 are laminated, the outer bottom wall of one plate body 100 is opposite to the inner bottom wall of the other plate body 100, and at the same time, the outer bottom wall is in sealing fit with the boss 160, so that the flow channel cavity formed between the two plate bodies 100 is only communicated with the two first through holes 130 and will not be communicated with the two second through holes 140.

[0049] In this embodiment, optionally, the guide ribs 110 located on the inner bottom wall of the plate body 100 extend along the width direction of the plate body 100, that is, the first direction is parallel to the width direction of the plate body 100. The guide ribs 110 are non-linear in their extending direction. In other words, the guide ribs 110 are bent or folded in their extending direction. That is, the guide ribs 110 include a plurality of sequentially connected guide segments in their extending direction, and the extending directions of any adjacent guide segments have an included angle.

[0050] Further, the included angle between any adjacent guide segments is 70°-120°. For example, the included angle between any adjacent guide segments is 70°, 105° or 120°, etc. By setting the guide segments as a bent structure, the flow guide channels 120 formed by adjacent guide segments are also bent structures. When the fluid flows in the flow guide channels 120, the flow path of the fluid in the channels is long and the required time is long, thereby increasing the heat exchange time and improving the heat exchange efficiency. At the same time, the included angle between any adjacent guide segments is 70°-120°, which ensures a small flow resistance of the flow guide channels 120 while satisfying the extension of the fluid flow time, so as to better improve the heat exchange efficiency.

[0051] Optionally, both ends of some of the guide ribs 110 in the first direction are abutted against the opposite sides of the annular flange 200, and the two ends of the remaining guide ribs 110 have a spacing from the opposite sides of the annular flange 200 respectively. Further, in the second direction, at least one guide rib 110 whose two ends are respectively spaced from the opposite sides of the annular flange 200 is arranged between two adjacent guide ribs 110 whose both ends are abutted against the annular flange 200. Wherein, the second direction is parallel to the length direction of the plate body 100, that is, the first direction is perpendicular to the second direction. It should be understood that in other embodiments, the first direction and the second direction may also be at other angles.

[0052] In other embodiments, one end of the guide rib 110 may have a spacing from the annular flange 200, and the other end may be abutted against the annular flange 200.

[0053] In other embodiments, the two ends of the flow guiding rib 110 in its length direction are respectively a first end and a second end. The first ends of some of the multiple flow guiding ribs 110 abut against the annular flange 200, and the first ends of the remaining flow guiding ribs 110 have a spacing from the annular flange 200. At the same time, the second ends of some of the multiple flow guiding ribs 110 abut against the annular flange 200, and the second ends of the remaining flow guiding ribs 110 have a spacing from the annular flange 200. In this way, at both ends of the flow guiding channel 120, there is a structure where the flow guiding ribs 110 abut against the annular flange 200 to increase the flow resistance, so that the fluid flowing to both ends of the flow guiding channel 120 neither directly bypasses the end of the flow guiding rib 110 nor needs to flow over the flow guiding rib 110. The flow field distribution is uniform, the flow disturbance effect is good, and the heat exchange efficiency is high.

[0054] In this embodiment, optionally, the annular flange 200 includes a first side 210, a third side 230, a second side 220, and a fourth side 240 that are sequentially connected end to end. The first side 210 and the second side 220 are opposite, and the third side 230 and the fourth side 240 are opposite. And the distance between the first side 210 and the second side 220 gradually increases from the side where the annular flange 200 is connected to the plate body 100 to the other side, and the distance between the third side 230 and the fourth side 240 gradually increases from the side where the annular flange 200 is connected to the plate body 100 to the other side. When adjacent plate bodies 100 are stacked, the outer peripheral wall of one of the two annular flanges 200 and the inner peripheral wall of the other form an annular sealing band, thereby achieving a sealed connection, and a flow channel cavity is formed between adjacent condenser forming plates.

[0055] In this embodiment, the two ends of some of the flow guiding ribs 110 respectively abut against the first side 210 and the second side 220 of the annular flange 200, and the two ends of the remaining flow guiding ribs 110 have a spacing from the first side 210 and the second side 220 of the annular flange 200.

[0056] Further, the annular flange 200 is provided with a marking portion, and the marking portion is provided as a plurality of notches 250 located on the side of the annular flange 200 away from the plate body 100. It should be noted that the plurality of notches 250 can be distributed on at least one of the first side 210, the second side 220, the third side 230, and the fourth side 240. For example, in this embodiment, the plurality of notches 250 are respectively located on the first side 210 and the third side 230.

[0057] At the same time, the height of the bottom wall of each notch 250 is higher than the height of the flow guiding rib 110. In other words, the distance between the bottom wall of each notch 250 and the plate body 100 is greater than the distance between the top wall of the flow guiding rib 110 and the plate body 100, so as to prevent the fluid in the flow channel cavity from leaking from the notch 250.

[0058] It should be noted that the plate body 100 and the annular flanging 200 can be integrally formed.

[0059] For the condenser forming plate provided in this embodiment, when multiple plate bodies 100 are assembled, the adjacent plate bodies 100 are rotated 180° and then assembled. Since the annular flanging 200 is provided with a notch 250, the notches 250 arranged at intervals are formed on the same side of the plate body 100, so that it is possible to better identify by the naked eye whether the forming plate is assembled incorrectly. At the same time, part of the flow guiding ribs 110 on the plate body 100 abuts against the annular flanging 200, and the rest has a spacing from the annular flanging 200, while making the flow field evenly distributed, reducing the flow resistance, and improving the heat exchange efficiency.

[0060] Please refer to Figures 4 - 6 , this embodiment also provides a condenser, including multiple condenser forming plates mentioned in the above embodiments. Multiple stacked condenser forming plates jointly define first flow channel cavities and second flow channel cavities that are alternately arranged in the stacking direction; multiple first flow channel cavities are connected, and multiple second flow channel cavities are connected.

[0061] It should be understood that two first through holes 130 are provided between any adjacent first flow channel cavities, and the two first through holes 130 are simultaneously connected to the adjacent first flow channel cavities; similarly, two second through holes 140 are provided between any adjacent second flow channel cavities, and the two second through holes 140 are simultaneously connected to the adjacent second flow channel cavities.

[0062] In this embodiment, optionally, the condenser further includes a first end plate 300 and a second end plate 400. Multiple condenser forming plates are clamped between the first end plate 300 and the second end plate 400; the first end plate 300 is provided with a first refrigerant joint 310, a second refrigerant joint 320, a first coolant joint 330 and a second coolant joint 340. Both the first refrigerant joint 310 and the second refrigerant joint 320 are connected to the first flow channel cavity; both the first coolant joint 330 and the second coolant joint 340 are connected to the second flow channel cavity.

[0063] It should be understood that in use, the first refrigerant joint 310 can be a refrigerant inlet joint, and the second refrigerant joint 320 can be a refrigerant outlet joint. The refrigerant is input from the first refrigerant joint 310 and flows out from the second refrigerant joint 320. Similarly, one of the first coolant joint 330 and the second coolant joint 340 is a coolant inlet joint, and the other is a coolant outlet joint.

[0064] In other embodiments, the condenser further includes a partition plate 500. The partition plate 500 is directly processed from a condenser forming plate, that is, one or two of the four through holes in the condenser forming plate are blocked to form the partition plate 500, and a blocking portion 520 is formed at the blocking position. The partition plate 500 is arranged between adjacent condenser forming plates and is used to change the flow direction of the fluid.

[0065] It should be noted that the number of the partition plates 500 is set as required, and a plurality of groove structures 510 are provided at the positions of the through holes blocked on the partition plates 500, so as to facilitate observation.

[0066] In this embodiment, optionally, the condenser further includes a liquid storage tank 600, and the first refrigerant joint 310 or the second refrigerant joint 320 is communicated with the liquid storage tank 600.

[0067] In this embodiment, the structure of the condenser is simple and reasonable. The flow field distribution in the flow channel cavity formed by stacking multiple condenser forming plates is uniform, the flow resistance is small, and the heat exchange efficiency of the condenser is high.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
