[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0035] As Figures 1-3 shown, the evaporator 100 provided by one of the embodiments of the present application includes a shell 110, an inner container 120 and a baffle 130. The shell 110 is provided with a containing cavity 101, an input port 102 and an output port 103, and the input port 102 and the output port 103 are both in communication with the containing cavity 101. The inner container 120 is connected to the shell 110 and is accommodated in the containing cavity 101, and the outer wall of the inner container 120 is spaced apart from the shell 110 to form a cooling cavity 104 for accommodating cooling medium, and the inner container 120 is used for accommodating an object to be cooled. The baffle 130 is arranged on the outer wall of the inner container 120, and the baffle 130 is configured to extend in the direction close to the cavity bottom of the containing cavity 101 (such as the direction Z shown in Figure 2 ).

[0036] Therefore, compared with the previous evaporator 100, the cooling medium is indirectly conducted to the cooled medium through the wall thickness of the evaporating tube, and the evaporator 100 of the present application can directly contact the inner container 120 (i.e. the cooled medium) to conduct heat, reduce the contact thermal resistance, and improve the efficiency of heat conduction. And under the action of the baffle 130, the cooling medium can be blocked to change the flow direction of the cooling medium, which is beneficial to strengthen the cooling medium flow to fill the cooling chamber 104.

[0037] In use, the cooling medium continuously enters the cooling chamber 104 through the input port 102 and gradually fills to the preset height and continuously outputs from the output port 103 during the delivery period. The heat of the object to be cooled accommodated in the inner container 120 is transferred to the cooling medium through the inner container 120, and the cooling purpose is achieved.

[0038] It should be noted that the cooling medium includes but is not limited to snow, chilled water, liquid nitrogen, as long as it is lower than the temperature outside the evaporator 100 and can absorb the heat of the inner container 120.

[0039] It can be understood that the shape of the outer shell 110 and the inner container 120 can be selected according to actual needs, which can be set as a cuboid shape, a cylindrical shape, and of course other irregular shapes, as long as the cavity for accommodating the cooling medium can be constructed between the outer shell 110 and the inner container 120.

[0040] The outer shell and the inner container 120 can be connected by welding, or can be connected by clamping, threaded connection or bonding, as long as the connection between the two is sealed to avoid leakage of the cooling medium.

[0041] In some embodiments, as shown in Figures 2-3 The inner container 120 includes a container body 121 and a convex edge 122, the convex edge 122 is annularly arranged on the container body 121, the container body 121 is accommodated in the receiving cavity 101, and the convex edge 122 is located outside the receiving cavity 101 and connected to the outer shell 110. Therefore, the convex edge 122 can quickly position the installation position between the inner container 120 and the outer shell 110, that is, it is convenient to position the depth of the inner container 120 arranged in the outer shell 110, which is beneficial to improve the assembly efficiency.

[0042] In some embodiments, along the direction of the convex edge 122 towards the bottom of the cavity of the receiving cavity 101 (as shown in the direction of Figure 2 The cross-sectional profile of the container body 121 gradually converges, that is, the outer peripheral size of the container body 121 gradually decreases, so that the object to be cooled can smoothly separate along the inner wall surface of the container body 121 after forming.

[0043] It should be understood that along theFigure 2 The outer periphery of the protruding rim 122 can be beyond the outer periphery of the shell 110 or flush with the outer periphery of the shell 110, which can be set as needed. In the embodiment, the outer periphery of the protruding rim 122 is beyond the outer periphery of the shell 110, and the part of the protruding rim 122 beyond the outer periphery of the shell 110 can be used to connect the inner container 120 to the outside.

[0044] For example, the protruding rim 122 is provided with a connecting hole 1221, and the inner container 120 can be connected to the outside through the connecting hole 1221. The number of connecting holes 1221 can be one, two or more, which can be set as needed. In the embodiment, the number of connecting holes 1221 is four, and the four connecting holes 1221 are arranged at intervals and located at the four perimeters of the protruding rim 122, which is conducive to balanced stress on the four perimeters of the protruding rim 122. It should be understood that the plurality of connecting holes 1221 provided on the protruding rim 122 can be arranged symmetrically or asymmetrically, which can be set as needed. For another example, the protruding rim 122 is provided with a protrusion (not shown in the figure), which is directly connected to the outside. For another example, the protrusion is provided with an adhesive, which is bonded to the outside.

[0045] In some embodiments, as shown in Figure 3 The number of baffles 130 is at least two, and the at least two baffles 130 are arranged at intervals. In the embodiment, the number of baffles 130 is two, and the two baffles 130 are located at the two sides of the container body 121, so as to block the cooling medium flowing to the two sides of the container body 121, so that the cooling medium flows to the bottom of the accommodating cavity 101 under the action of the baffles 130, which is conducive to strengthening the flow of the cooling medium. In the embodiment, the two baffles 130 abut against the inner wall surface of the shell 110, and the ends of the two baffles 130 away from the bottom of the accommodating cavity 101 are connected to the protruding rim 122, and the ends of the two baffles 130 close to the bottom of the accommodating cavity 101 have a flow-through gap with the shell 110, so that the cooling medium flows to the flow-through gap under the blocking of the baffles 130 and flows to the output port 103.

[0046] In some embodiments, as shown in Figures 2-3 The evaporator 100 further comprises a first connecting pipe 140 and a second connecting pipe 150, the first connecting pipe 140 is arranged at the input port 102, and the second connecting pipe 150 is arranged at the output port 103. In this way, under the action of the first connecting pipe 140 and the second connecting pipe 150, the structure for supplying the cooling medium to the outside is connected, which is convenient.

[0047] The evaporator 100 provided by the embodiment of the present application comprises an outer shell 110, an evaporating inner shell and a baffle 130. The outer shell 110 is provided with a containing cavity 101, an input port 102 and an output port 103. The input port 102 and the output port 103 are both communicated with the containing cavity 101. The inner container 120 is connected to the outer shell 110 and is contained in the containing cavity 101. The outer wall of the inner container 120 is arranged in a spaced manner with the outer shell 110 to form a cooling cavity 104. The inner container 120 is used for containing an object to be cooled. The cooling cavity 104 is used for containing a cooling medium. The baffle 130 is arranged on the outer wall of the inner container 120 and is configured to extend in a direction close to the cavity bottom of the containing cavity 101. In this way, compared with the mode that the cooling medium conducts heat indirectly with the cooled medium through the thick wall of the evaporating pipe, the evaporator 100 with the above structure can make the cooling medium directly contact with the inner container 120 to conduct heat, thereby reducing the contact thermal resistance and being beneficial to improving the heat conduction efficiency.

In this way, the plurality of evaporators 100 are communicated with each other through the plurality of connecting pipes 210, which is beneficial to supplying the cooling medium to the plurality of evaporators 100. In the embodiment, the number of the evaporators 100 is three and the number of the connecting pipes 210 is two. The three evaporators 100 are arranged in a spaced manner along a straight line.

[0049] In some embodiments, the evaporating module 200 further comprises a fixing support (not shown in the figure). The fixing support is connected with the plurality of evaporators 100 respectively, so that the plurality of evaporators 100 are fixed on the same fixing support at the same time, which is beneficial to modular installation and improves the installation efficiency.

[0050] In use, the cooling medium is input from the input port 102 of the leftmost evaporator 100 shown in the figure, is output from the first connecting pipe 210 after flowing through the cooling cavity 104 of the leftmost evaporator 100 and is input into the input port 102 of the middle evaporator 100. Then, the cooling medium flows in the cooling cavity 104 of the middle evaporator 100, is output from the second connecting pipe 210 and is input into the rightmost evaporator 100. After flowing in the cooling cavity 104 of the rightmost evaporator 100, the cooling medium is output, thereby realizing the heat conduction of the cooling medium to the plurality of evaporators 100.
