[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] In the description of the present invention, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In this embodiment, the heat exchanger core module 100 is not a complete heat exchanger, but a unitized structure of the finished heat exchanger. For example, two fin heat exchangers with different inner diameters of the coil 105 are artificially called large coil heat exchangers and small coil heat exchangers, and the only difference between the two is the inner diameter of the coil 105. Before testing, a heat exchanger core module 100 with the same external size (occupying the same external volume) is first manufactured, and then the first manifold 103 is used to connect the liquid inlet pipeline 101 of each layer of the large coil heat exchanger, and the second manifold 104 is used to connect the liquid outlet pipeline 102 of each layer of the small coil heat exchanger. Then, the large coil heat exchanger core module 100 with the same external size and the small coil heat exchanger core module 100 are placed in the core module detection chamber to start testing. Of course, in actual testing, there may be different numbers of coils 105 and different fin shapes. As long as the external dimensions are the same, the actual total heat exchange area and the unit heat exchange area of ​​the heat exchanger can be calculated.

[0035] First embodiment

[0036] See attached Figure 1 and Figure 2The utility model also provides a movement module detection bin, including a bin cover 2 and a bin body 1, wherein the bin cover 2 is detachably connected to the bin body 1. The bin body 1 in this embodiment includes a bin body and a movable door plate 12, wherein the bin body includes a first side plate 15, a second side plate 16, a third side plate 17 and a bottom plate 13, wherein the first side plate 15 and the second side plate 16 are arranged at intervals, and the first side plate 15 and the second side plate 16 are arranged oppositely, and the two sides of the third side plate 17 are respectively connected to the first side plate 15 and the second side plate 16, and the bottom side of the first side plate 15, the bottom side of the second side plate 16 and the bottom side of the third side plate 17 are all fixed on the bottom plate 13, and the bin body has an inner cavity, and the inner cavity has a side opening and a top opening, and the movable door plate 12 is detachably connected to the bin body so as to be able to close the side opening. An air inlet is arranged on the first side plate 15, and an air outlet is arranged on the second side plate 16, and the air inlet and the air outlet are respectively connected to the inner cavity.

[0037] The movable door plate 12 is provided with a clearance groove 18 which runs through the thickness direction thereof. The clearance groove extends from the bottom surface of the movable door plate 12 toward the top surface, that is, extends in the vertical direction. The bottom end of the clearance groove 18 runs through the bottom surface of the movable door plate 12, and the top end of the clearance groove 18 is located below the top surface of the movable door plate 12. Two clearance grooves 18 are provided, and the two clearance grooves 18 are parallel to each other. One clearance groove 18 is used to avoid the liquid inlet pipeline 101 of the heat exchanger core module, and the other clearance groove 18 is used to avoid the liquid outlet pipeline 102 of the heat exchanger core module.

[0038] After the heat exchanger core module 100 is placed into the inner cavity from the side opening or the top opening, the movable door plate 12 moves toward the bottom plate 13 until the side opening is closed, so that the liquid inlet pipe 101 of the heat exchanger core module 100 enters one of the make way grooves and the liquid outlet pipe 102 of the heat exchanger core module 100 enters the other make way groove.

[0039] After the movable door panel 12 is installed in the bin body, the bin cover 2 covers the top opening and is connected to the bin body 1, and the bin cover 2 and the bin body form a cube-shaped core module detection bin. Otherwise, the heat exchanger core module 100 can be removed from the inner cavity.

[0040] In this embodiment, firstly, this embodiment uses a unitized heat exchanger core module 100 to test the heat exchange efficiency of the heat exchanger, which is small and light compared to the existing finished heat exchanger detection device.

[0041] Furthermore, since the bin body, the movable door panel 12 and the bin cover 2 in this embodiment are all made of plate-like materials of heat-insulating materials, and the bin is filled with heat-insulating cotton, the structure is simple and the cost is low, and it is suitable for small and medium-sized enterprises.

[0042] In this embodiment, the core module detection chamber also includes thermal insulation cotton, which is arranged in the gap between the heat exchanger core module 100 and the side wall of the inner cavity, and is also used to fill the clearance groove 18 and close the clearance groove 18. The thermal insulation cotton fills the gap and cavity between the heat exchanger core module 100 and the core module detection chamber, so that the heat exchanger core module 100 and the core module detection chamber are relatively isolated, reducing the air heat from entering and exiting the heat exchanger core module 100. However, it should be emphasized that the thermal insulation cotton is only filled between the inner wall of the core module detection chamber and the heat exchanger core module 100, and the thermal insulation cotton is not filled into the air inlet and outlet, otherwise it is easy to reduce the flow rate and flow of hot air, affecting the normal test of the experiment.

[0043] Reference Figure 3 and Figure 4 In this embodiment, it also includes an air inlet pipe 3 and an air outlet pipe 4. The air inlet pipe 3 has an air inlet end 31 and an air outlet end 32. The air inlet end 31 is connected to the air inlet, and the air outlet end 32 is connected to the air source. The air outlet pipe 4 has an inlet end 41 and an outlet end 42. The inlet end 41 is connected to the air outlet, and the outlet end 42 is connected to the outside.

[0044] In the present embodiment, hot air is passed into the detection chamber of the core module, and cold fluid is passed into the heat exchanger core module 100. The gas inlet and outlet temperatures are measured at the air inlet and outlet, and the liquid inlet pipeline 101 and the liquid outlet pipeline 102 of the heat exchanger core module 100 measure the liquid inlet and outlet temperatures, thereby obtaining the temperature of the hot fluid before and after the heat exchange and the temperature of the cold fluid before and after the heat exchange.

[0045] In this embodiment, the air inlet pipe 3 is a straight pipe, and the cross section of the air inlet pipe 3 gradually decreases from the air inlet end 31 to the air outlet end 32. The air inlet pipe 3 is not a curved pipe, and the axis of the air inlet pipe 3 is a straight line, but the cross section of the air inlet pipe 3 changes, and the cross section gradually increases, so that the air can evenly cover the heat exchanger core module 100. That is, the gas in the air inlet pipe 3 gradually disperses toward the peripheral surface of the air inlet pipe 3, and will not be all concentrated at the central axis of the air inlet pipe 3, so that the air entering the core module detection chamber is also dispersed around the core module detection chamber.

[0046] In contrast to the air inlet pipe 3, the cross-section of the air outlet pipe 4 gradually expands from the inlet end 41 to the outlet end 42, and the air outlet pipe 4 evenly gathers the gas in the movement module detection chamber; if the air outlet pipe 4 has a uniform cross-section, the gas in the movement module detection chamber can easily form turbulence at the connection between the air outlet pipe 4 and the second side plate 16, so that the gas collides with the second side plate 16 or the air outlet pipe 4, generating noise.

[0047] In this embodiment, a handle is fixed on the bin cover 2. The handle is fixed on the outside of the bin cover 2, that is, fixed on the side of the bin cover 2 away from the bin body 1, so as to facilitate people to carry it.

[0048] In this embodiment, the bin cover 2 includes a cover plate 21 and a ring edge 22 surrounding the cover plate 21, the ring edge 22 is fixed to a side of the cover plate 21 close to the bin body 1, and the ring edge 22 is arranged outside the side wall of the bin body 1. A sealing gasket is arranged between the ring edge 22 and the side wall of the bin body 1. The sealing gasket fills the gap between the ring edge 22 and the bin body 1 to increase the sealing performance of the movement module detection bin. If the ring edge 22 is fitted to the side wall of the bin body 1, high processing accuracy is required and the cost is increased. Therefore, in this embodiment, an annular sealing gasket is added between the ring edge 22 and the bin body 1, and the sealing gasket can be fixed on the bin cover 2, and the elastic sealing gasket is used to improve the sealing performance of the movement module detection bin.

[0049] In this embodiment, the middle of the bottom plate 13 is recessed toward the bin cover 2 to form a workbench, the top surface of which is a plane, and the workbench is used to carry the heat exchanger core module 100. The bin body also includes a workbench, which is arranged on the bottom plate 13, the top surface of which is a plane, and the workbench is used to carry the heat exchanger core module 100. The workbench 14 can be a solid structure or a hollow structure, and the top surface of the workbench 14 carries the heat exchanger core module 100.

[0050] The workbench 14 has a top wall and side walls. The number of the side walls of the workbench 14 is consistent with the number of the sides of the bottom plate 13. The side walls of the workbench fit the side walls of the warehouse. The workbench 14 in this embodiment is in a cube shape. After the movable door plate 12 is fixed, the side walls of the workbench 14 fit the side walls of the warehouse respectively, thereby enhancing the sealing performance between the workbench 14 and the warehouse. In actual processing, there may be leakage points between the side walls and the bottom wall of the warehouse, especially there is a high probability of gaps between the movable door plate 12 and the bottom plate 13. After the side walls of the workbench 14 fit the inner surface of the movable door plate 12, it can reduce the escape of gas from the leakage points or gaps.

[0051] In this embodiment, the workbench 14 and the inner wall of the bin body are used to form a limiting structure. When the movement module is placed in the bin body, it is already in the best detection position.

[0052] Second embodiment

[0053] The difference between this embodiment and the first embodiment is that the ring edge fits the side wall of the chamber body, which can also ensure the sealing performance of the movement module detection chamber.

[0054] Third embodiment

[0055] The difference between this embodiment and the first embodiment is that the warehouse body also includes a workbench, which is arranged on the bottom plate, the top surface of which is a plane, and the workbench is used to carry the heat exchanger core module. The workbench can be a solid structure or a hollow structure, and the top surface of the workbench carries the heat exchanger core module. In this embodiment, the workbench is a separate workpiece and can be fixed to the bottom plate by welding, bolts, etc.

[0056] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
