[0047] The technical solutions in the present disclosure will be described clearly and completely below in conjunction with the drawings in the present disclosure. Obviously, the described disclosure is only a part of the present disclosure, not the whole disclosure. The following description of at least one exemplary disclosure is actually only illustrative, but not as any limitation on the present disclosure and its application or use. Based on the disclosure in the present disclosure, all other disclosures obtained by those skilled in the art without creative labor fall within the scope of the present disclosure.

[0048] As shown in the drawings, Figures 1-16 One of the present disclosure provides an evaporator 10, comprising an evaporator body 11 and a working medium guiding structure 13 arranged in the cavity of the evaporator body 11, wherein the evaporator body 11 is a hollow structure with a hollow cavity, specifically, the evaporator body 11 can be provided with a first side wall 111 and a second side wall 114 as two oppositely arranged side walls, and a hollow cavity structure is formed by other side walls.

[0049] The outer surface of the first side wall 111 of the evaporator body 11 is provided with a heat source module 42 comprising at least one heating point 421 (i.e. the heat source module 42 in the present disclosure comprises one or more than one heating point 421, and each heating point 421 corresponds to a heated area 1101 on the first side wall 111). The heat generated by the heat source module 42 is conducted to the first side wall 111. The inner surface of the first side wall 111 of the evaporator body 11 corresponds to the area of the heating point 421, which is the heated area 1101, as shown in the drawings. Figures 2-13As shown, the inner surface area of the first side wall 111 corresponding to the larger dashed line box is the heated area 1101, and the smaller dashed line box is the heating point 421. The working medium guiding structure 13 is at least partially arranged in the heated area 1101 or above the heated area 1101, and the working medium guiding structure 13 has a guiding surface 1301 for stopping and guiding the rising gas-phase working medium in the evaporator body 11, and the guiding surface 1301 extends away from the heated area 1101. It can be understood that the end of the working medium guiding structure 13 towards the first side wall 111 can be connected to the inner surface of the first side wall 111.

[0050] It can be understood that the inner surface of the first side wall 111 in the present disclosure refers to the surface of the first side wall 111 facing the second side wall 114, and similarly, the inner surface of the second side wall 114 refers to the surface of the second side wall 114 facing the first side wall 111. The heat source module 42 can also be arranged on the inner surface of the first side wall 111.

[0051] For example, the outer surface of the first side wall 111 is provided with two or more heating points 421 arranged from top to bottom in the first direction, and each heating point 421 corresponds to one or more heated areas 1101. In the prior art, the liquid working medium in the lower heated area 1101 is partially vaporized after being heated, and the high-temperature gas-phase working medium after vaporization rises under the action of buoyancy and then passes through the upper heated area 1101. At this time, the high-temperature gas-phase working medium will interfere with the heat exchange effect of the liquid-phase working medium in the upper area during the rising process, thereby reducing the heat dissipation capacity of the evaporator in the upper heated area 1101. However, in the present disclosure, the working medium guiding structure 13 is arranged on the inner surface of the first side wall 111 of the evaporator body 11, and the guiding surface 1301 of the working medium guiding structure 13 guides the vaporized working medium to at least one side away from the heated area 1101, thereby reducing the influence of the vaporized working medium after heat absorption and vaporization in the lower layer of the heated area 1101 on the heat exchange effect of the upper layer of the heated area 1101 during the rising process, and further improving the heat dissipation effect of the evaporator 10 on the heating point 421 and the heat source module 42.

[0052] It can be understood that the side wall of the evaporator body 11 provided with the heat source module 42 is the first side wall 111; the heated area 1101 is the projection area of the heating point 421 of the heat source module 42 on the inner surface of the first side wall 111; or the heated area 1101 is the position or area of the first side wall 111 and the internal temperature of the evaporator 10 rising by a certain amplitude when the heating point 421 of the heat source module 42 is working. In actual application, the projection of the position or area with the temperature rising by a certain amplitude on the first side wall 111 can be the area obtained by scaling the projection of the heating point 421 of the heat source module 42 on the first side wall 111 by a certain proportion. The projection area is as shown in the following figure.Figures 5-13 It is to be noted that when the projection of the heated area 1101 on the first side wall 111 is large, the projection of the working medium guiding structure 13 on the first side wall 111 will pass through the projection of the heated area 1101, that is, the working medium guiding structure 13 is at least partially arranged in the heated area 1101. Conversely, when the projection of the heated area 1101 on the first side wall 111 is small, the projection of the working medium guiding structure 13 on the first side wall 111 will be located above the projection of the heated area 1101 and spaced therefrom, that is, the working medium guiding structure 13 is at least partially arranged above the heated area 1101. That is, the arrangement of the working medium guiding structure 13 will change according to the actual size of the heated area 1101.

[0053] In a second aspect, as shown in Figure 5 , Figure 6 , Figure 9 indicated, the working medium guiding structure 13 extends in a direction that has a non-zero angle with the first direction; as Figure 8 indicated, the working medium guiding structure 13 can also extend in the second direction; as Figure 1 and Figure 7 indicated, the working medium guiding structure 13 can also extend in both the direction that has a non-zero angle with the first direction and the second direction. Further, the working medium guiding structure 13 can be a strip-shaped plate structure as shown in Figure 1 , Figure 6 , Figure 7 , Figure 8 , or a block structure as shown in Figure 9 .

[0054] As shown in Figure 1 , Figure 6 , Figure 7 , Figure 9 , Figure 11 , Figure 13 indicated, the bottom wall surface extending downward in the first direction is a guiding surface 1301. As shown in Figure 10 , or, the side wall inclined with respect to the first direction and the second direction forms the guiding surface 1301; or as shown in Figure 8 , Figure 14 , Figure 15 , Figure 16 indicated, the bottom wall surface perpendicular to the first direction and the wall surface inclined with respect to the first direction and the second direction together form the guiding surface 1301 in the shape of a flat-bottomed bowl; wherein the first direction is parallel to the upward direction of the gas-phase working medium in the evaporator body 11 (i.e., the height direction from bottom to top of the evaporator body 11 in Figure 1 ), and the second direction is a direction parallel to the plane in which the first side wall 111 is located and orthogonal to the first direction (i.e., the direction parallel to the plane in which the first side wall 111 is located in Figure 1The length direction of the evaporator body 11 from the middle to the two sides. In this way, the gas phase working medium can be guided to either side of the length direction of the evaporator body 11 according to the actual situation, and it is ensured that the gas phase working medium below does not affect the heat exchange of the heating area 1101 above.

[0055] It should be noted that the "working medium guiding structure 13 is at least partially arranged in the heating area 1101" in the present disclosure means that the edge of the inner surface contact surface of the working medium guiding structure 13 and the side wall of the evaporator body 11 (the side wall of the evaporator body 11 in the present disclosure is the first side wall 111 provided with the heat source module 42) will pass through the heating area 1101. At this time, the heating area 1101 can be divided into two parts by the working medium guiding structure 13, and "away from the gas phase working medium movement path" can be understood as a direction parallel to the second direction or other directions having a certain angle with the second direction and the first direction. For example Figure 1 , Figure 13 The inverted eight-shaped oblique extension can also be a positive eight-shaped oblique extension; of course, it can also be extended from the upper left to the lower right as shown in Figure 6 Similarly, it can also be extended from the upper right to the lower left. The guiding surface 1301 extends away from the heating area 1101 to guide the rising gas phase working medium to at least one side, wherein the at least one side includes both sides in the length direction of the evaporator body 11 and one side in the thickness direction of the evaporator body 11.

[0056] Further, in the third direction (the third direction is the direction of the outer surface of the first side wall 111 facing the inner surface and perpendicular to the first side wall 111, which can also be understood as Figure 1 the thickness direction of the evaporator body 11), one end of the working medium guiding structure 13 extends to the first side wall 111 and is fixed on the inner surface of the first side wall 111 to realize the installation and fixation of the working medium guiding structure 13. The other end of the working medium guiding structure 13 can be selected according to the actual situation whether to extend to the other side wall (i.e. the second side wall 114) opposite to the first side wall 111, that is, the edge of the working medium guiding structure 13 away from the heating area 1101 extends to the second side wall 114 in the third direction, or extends to a position spaced from the second side wall 114. In the present disclosure, the other end of the working medium guiding structure 13 is partially or entirely extended to the other side wall (i.e. the second side wall 114) opposite to the first side wall 111 to ensure the fixation effect of the working medium guiding structure 13 and the flow guiding effect and reliability of guiding the gas phase working medium to the two sides in the length direction.

[0057] Optionally, as shown in Figure 13In the illustrated disclosure, the other end of the working medium guiding structure 13 is spaced from the second side wall 114, and the bottom edge or side edge of the working medium guiding structure 13 towards the second side wall 114 can also be provided as an inclined guiding surface 1301, that is, in the first direction, the height of the end of the working medium guiding structure 13 in contact with the first side wall 111 is lower than the height of the end of the working medium guiding structure 13 towards the second side wall 114, thereby achieving the guiding of the gas-phase working medium to the area of the evaporator body 11 away from the first side wall 111 in the thickness direction, in combination with the aforementioned guiding of the working medium guiding structure 13 to the gas-phase working medium in the second direction, the gas-phase working medium can be guided to at least three sides, further ensuring the reliability of heat exchange in the upper heating area 1101.

[0058] In a third aspect, the working medium guiding structure 13 is at least one, and in the case of multiple working medium guiding structures 13, as shown in Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 14 illustrated, the plurality of working medium guiding structures 13 can be spaced and distributed to form a column in the first direction, or as Figure 15 、 Figure 16 illustrated, the plurality of working medium guiding structures 13 are spaced and distributed to form a row in the second direction; or as Figure 1 、 Figure 13 、 Figure 15 、 Figure 16 illustrated, the plurality of working medium guiding structures 13 form a matrix arrangement of multiple rows and multiple columns.

[0059] In a fourth aspect, in the present disclosure, the number of working medium guiding structures 13 corresponding to each heat source module 42 can be adjusted according to actual conditions, and similarly, the number of heat points 421 included in each heat source module 42 can also be adjusted according to actual conditions. As shown in Figure 6 (a)、 Figure 10 (a)、 Figure 11 (a) illustrated disclosure, a plurality of heat points 421 of a heat source module 42 correspond to one working medium guiding structure 13; as Figure 5 (a)、 Figure 7 (a)、 Figure 8 (a)、 Figure 9 (a) illustrated disclosure, a plurality of heat points 421 of a heat source module 42 correspond to two working medium guiding structures 13 spaced in the first direction; in the disclosure as Figure 1 、 Figure 13 , one heat source module 42 corresponds to two or more working medium guiding structures 13, and the plurality of working medium guiding structures 13 are spaced in the first direction and the second direction. Similarly, as Figure 5 (b)、 Figure 6 (b)、 Figure 7(b)、 Figure 8 (b)、 Figure 9 (b)、 Figure 10 (b)indicates that each heat source module 42 only includes one heat point 421, that is, the heat source module 42 itself is a heat point 421, and one working medium guiding structure 13 can correspond to multiple heat source modules 42, wherein multiple heat points 421 are arranged in sequence and at intervals along the second direction, or arranged in sequence and at intervals along the first direction, or arranged in matrix along the second direction and the first direction as shown in Figure 5 indicates. In this way, the guiding surface 1301 can be arranged at different positions to ensure the guiding of the rising gas-phase working medium at different positions of the heated area 1101 and ensure the reliability of the guiding of the gas-phase working medium. Further, in order to improve the adaptability under multiple working conditions, as shown in Figure 14 indicates that each heat source module 42 includes multiple heat points 421, and all heat points 421 of multiple heat source modules 42 are arranged in matrix along the second direction and the first direction, and the working medium guiding structure 13 can be located above multiple heat points 421 in the same row along the second direction or pass through the heated areas 1101 corresponding to the multiple heat points 421 in the same row. Figure 6 (b)indicates, Figure 6 (b)indicates,

[0060] It should be noted that, in general, one heat source module 42, such as one IGBT module, can only include one chip, that is, one heat point 421, at this time one heat point 421 is equivalent to one heat source module 42. However, with the improvement of the integration of the heat source module 42, two or more chips can also be arranged in one heat source module 42, and each chip corresponds to one heated area 1101, that is, one heat source module 42 has multiple heated areas 1101, and the multiple heated areas 1101 can be arranged at intervals along the first direction, or arranged at intervals along the second direction, or arranged at intervals along the first direction and the second direction. The working medium guiding structure 13 can be arranged above the lowermost heat point 421 (heated area 1101) in the heat source module 42 or pass through the heated area 1101 corresponding to the heat point 421, as shown in Figures 5-10 indicates that the specific arrangement of the working medium guiding structure 13 is the same as the arrangement of the working medium guiding structure 13 relative to the heat source module 42, and the difference is that the heat point 421 is used instead of the heat source module 42 in the present disclosure.

[0061] It can be understood that the plurality in the present application is two or more. One or more of the heat source modules 42 or the corresponding heated area 1101 above it is not provided with a working medium guide structure 13, or one or more of the heat generating points 421 or the corresponding heated area 1101 above it is not provided with a working medium guide structure 13.

[0062] At least one part of the working medium guide structure 13 is located in or above at least two heated areas 1101, wherein the at least two heated areas 1101 are distributed along the second direction. In this way, any working medium guide structure 13 can be provided corresponding to at least two heated areas 1101 and can stop and guide the rising gas phase working medium in the at least two heated areas 1101, thereby improving the utilization rate of the working medium guide structure 13. It can be understood that in the case of Figure 5 (a) to Figure 10 (a) shown in the disclosure, the at least two heated areas 1101 can belong to the same heat source module 42, and in the case of Figure 5 (b) to Figure 10 (b) and as Figures 11-16 shown in the disclosure, the at least two heated areas 1101 can also belong to different heat source modules 42.

[0063] In the fifth aspect, in order to avoid the influence of the gas phase working medium generated by the lower heat generating point 421 or heat source module 42 on the upper heat generating point 421 or heat source module 42, and to ensure the reliability of the gas phase working medium guide, the projection of the opposite ends of the at least two working medium guide structures 13 in the first direction towards the horizontal plane overlaps. Specifically, as Figure 14 shown, in the case of multiple working medium guide structures 13, taking one of the working medium guide structures 13 as an example, in the second direction, the two ends of the working medium guide structure 13 farthest apart extend above the two heat generating points 421 farthest apart. The two ends of each working medium guide structure 13 farthest apart extend to the two sides of the two heat generating points 421 or heat source modules 42 farthest apart. The projection of each working medium guide structure 13 in the first direction on the horizontal plane overlaps or overlaps completely.

[0064] Alternatively, the width of the projection of the working medium guide structure 13 on the horizontal plane in the second direction is greater than or equal to the width of the projection of the heat generating point 421 on the horizontal plane in the second direction. As Figure 5 shown, the projection of the working medium guide structure 13 above the horizontal plane in the first direction is within the range of the projection of the working medium guide structure 13 above the horizontal plane in the first direction; and as Figure 13As shown, the plurality of working medium guiding structures 13 form two rows, each row extending up and down along the first direction, the right end of the working medium guiding structure 13 in the left row is above or below the left end of the working medium guiding structure 13 in the right row, and the projection of the right end of the working medium guiding structure 13 in the left row on the horizontal plane along the first direction falls within the projection range of the working medium guiding structure 13 in the right row on the horizontal plane along the first direction, and similarly, the projection of the left end of the working medium guiding structure 13 in the right row on the horizontal plane along the first direction falls within the projection range of the working medium guiding structure 13 in the left row on the horizontal plane along the first direction.

[0065] Preferably, the overlapping positions of the plurality of working medium guiding structures 13 are mainly in the middle of the cavity of the evaporator body 11, which can ensure that the rising gas-phase working medium is guided by the stopper, avoid the case that the heat exchange effect of the upper heat receiving area 1101 of the gap extending along the first direction between the plurality of working medium guiding structures 13 is poor, ensure the guiding effect of the guiding surface 1301 on the gas-phase working medium, and avoid the invalid setting of the guiding surface 1301.

[0066] Further, the extension length and extension height of the working medium guiding structure 13 in the oblique direction (the direction corresponding to the angle between the first direction and the second direction) can be further extended, and the gas-phase working medium can be completely guided out of the heat receiving area 1101, and the heat exchange effect of the upper heat receiving area 1101 is ensured.

[0067] Further, as shown in Figure 6 , Figure 9 and Figure 11 , in the first direction (height direction), the lowest one of the working medium guiding structures 13 can extend to the height of the lowest heating point 421, and similarly, the highest one of the working medium guiding structures 13 can extend to the height of the highest heating point 421.

[0068] Similarly, as shown in Figure 14 , Figure 15 and Figure 16 , in the second direction (width direction), the leftmost one of the working medium guiding structures 13 along the first direction can extend to the left side of the leftmost heating point 421, and similarly, the rightmost one of the working medium guiding structures 13 along the first direction can extend to the right side of the rightmost heating point 421.

[0069] In the case that the working medium guiding structure 13 is multiple, in the first direction, the two ends of any working medium guiding structure 13 with the furthest relative distance respectively extend to at least two heat points 421 with the closest relative distance located on both sides of the working medium guiding structure 13, the two ends with the furthest relative distance of the multiple working medium guiding structures 13 respectively extend to the two heat points 421 with the furthest relative distance, and at least part of the working medium guiding structures 13 partially overlap in the first direction. In this way, the guiding effect of the gas-phase working medium can be further ensured.

[0070] It should be noted that the "in the case that the working medium guiding structure 13 is one" in the present disclosure includes the case that one heat source module 42 or one heat point 421 corresponds to one working medium guiding structure 13, and also includes the case that multiple heat source modules 42 or multiple heat points 421 correspond to the same working medium guiding structure 13.

[0071] Among them, the working medium guiding structure 13 has at least one guiding surface 1301, and the projection of the working medium guiding structure 13 on the first side wall 111 can be one or a combination of multiple of the following shapes: a triangle (as shown in Figure 9 ), a meandering shape (as shown in Figure 10 ), an inclined straight line shape (as shown in Figure 11 ), an arc shape (as shown in Figure 1 , Figure 6 , Figure 13 , a V shape (as shown in Figure 5 ), a round-bottomed bowl shape (as shown in Figure 7 ), a flat-bottomed bowl shape (as shown in Figure 8 , Figure 14 , Figure 15 , Figure 16 ). It can be understood that the shape of the projection of the working medium guiding structure 13 on the first side wall 111 is not limited to the above shapes. In this way, the working medium guiding structure 13 can be adapted according to the actual situation to improve the guiding effect of the gas-phase working medium.

[0072] Taking the disclosure shown in Figure 1 as an example, one heat source module 42 has 3 rows of heat points 421 in the first direction, each row has at least 2 heat points 421 spaced apart in the second direction, the working medium guiding structure 13 is 4, the 4 working medium guiding structures 13 are spaced apart in the first direction and the second direction, the 4 working medium guiding structures 13 are distributed in 2x2, and the two columns of working medium guiding structures 13 in the same row are oppositely arranged in an inverted eight-character shape. The projection of each working medium guiding structure 13 on the vertical plane formed by the first direction and the second direction is an upward arc-shaped strip-shaped structure. The two ends of at least one working medium guiding structure 13 in the second direction respectively protrude on both sides of the corresponding column of heat points 421, Figure 1The projection of the heat-generating points 421 in the middle right column on the horizontal plane (the plane defined by the second direction and the third direction) is located in the right column. The projection of the working medium guiding structure 13 on the horizontal plane is within the projection range of the heat-generating points 421.

[0073] The working medium guiding structure 13 can be arranged above the heat-generating points 421 in each row except the heat-generating points 421 in the top row. The guiding surface 1301 formed by the bottom of the working medium guiding structure 13 is an arc surface. The shape of the working medium guiding structure 13 in the present disclosure is convenient for processing, and is conducive to installation according to the dispersion of the heat-generating points 421 to ensure the guiding effect on the gas-phase working medium.

[0074] Further, in order to improve the guiding effect, the two ends of any working medium guiding structure 13 in the first direction respectively extend to the heat-generating points 421 in the adjacent row, for example, to the heat-generating points 421 in the row above the heat-generating points 421 in the row where the working medium guiding structure 13 is located. Figure 1 Taking the working medium guiding structure 13 in the middle right column as an example, the left end of the working medium guiding structure 13 above the heat-generating points 421 in the bottom row is located above the heat-generating points 421 in the bottom row, the right end of the working medium guiding structure 13 is located at the height of the heat-generating points 421 in the middle row, and the height of the right end of the working medium guiding structure 13 in the first direction is higher than that of the left end.

[0075] Of course, it can be understood that no working medium guiding structure 13 is arranged above the heat source module 42 or the heat-generating point 421 with low heat generation or less affected by the heat source module or the heat-generating point 421 below.

[0076] Taking the working medium guiding structure 13 in the middle right column as an example, the left end of the working medium guiding structure 13 above the heat-generating points 421 in the bottom row is located above the heat-generating points 421 in the bottom row, the right end of the working medium guiding structure 13 is located at the height of the heat-generating points 421 in the middle row, and the height of the right end of the working medium guiding structure 13 in the first direction is higher than that of the left end. Figure 5 Taking the fifth disclosed embodiment shown in FIG. 5 as an example, one heat source module 42 has 3 rows of heat-generating points 421 in the first direction, each row has 2 heat-generating points 421 distributed at different heights along the second direction, and the working medium guiding structure 13 is 2, the 2 working medium guiding structures 13 are arranged in the first direction, and the working medium guiding structure 13 is a V-shaped strip-shaped structure.

[0077] The 2 working medium guiding structures 13 are arranged in the region between the adjacent 2 rows of heat-generating points 421, the guiding surface 1301 formed by the bottom of the working medium guiding structure 13 is a V-shaped plane below the two intersection positions, the two ends of the working medium guiding structure 13 in the first direction respectively extend to the height of the heat-generating points 421 in the row above, and the two ends of the working medium guiding structure 13 in the second direction respectively protrude to the 2 columns of heat-generating points 421. The shape of the working medium guiding structure 13 in the present disclosure is convenient for forming two guiding surfaces 1301 at the same time, and the size of the guiding surface 1301 in the second direction can be processed by adjusting the size of the working medium guiding structure 13 in the second direction, which is convenient for the guiding surface 1301 to completely guide the rising gas-phase working medium to the two sides of the heating area 1101 in the second direction.

[0078] In practical applications, in order to adapt more flexibly to different working conditions, the dimensions of each working medium guide structure 13 can be the same or different. For example, the width of the upper working medium guide structure 13 in the second direction is smaller than the width of the lower working medium guide structure 13 in the second direction, or the width of the upper working medium guide structure 13 in the second direction is greater than the width of the lower working medium guide structure 13 in the second direction.

[0079] by Figure 6 Taking the example of the sixth disclosure shown, a heat source module 42 has 6 heating points 421, which are distributed above and below the working fluid guiding structure 13. The working fluid guiding structure 13 is a strip-shaped plate structure with a projected upward arc shape, located between the two rows of heating points 421. Its two ends in the first direction extend to the two farthest heating points 421 in the first direction, and its two ends in the second direction extend to the two farthest heating points 421 in the second direction. The guide surface 1301 formed at the bottom of the working fluid guiding structure 13 is an arc-shaped surface.

[0080] The working fluid guiding structure 13 in this disclosure has a shape that is easy to process and is conducive to the distribution and installation according to the dispersion of the heating points 421 to ensure the guiding effect on the gas phase working fluid.

[0081] Of course, such as Figure 6 As shown, the six heating points can be equally distributed above and below the working fluid guiding structure 13. The number of heating points 421 above and below the working fluid guiding structure 13 can also be unequal. For example, there can be four above and two below, or two above and four below.

[0082] by Figure 7 Taking the disclosed seventh example, the specific arrangement of its working fluid guiding structure 13 is similar to... Figure 5The working fluid guiding structure 13 is set in a similar way, the only difference being the shape of the working fluid guiding structure in the two schemes. A heat source module 42 has 3 rows of heating points 421 in the first direction, and each row has 2 heating points 421 distributed at intervals along the second direction. There are 2 working fluid guiding structures 13, which are arranged at intervals in both the first and second directions. The working fluid guiding structure 13 is a strip plate structure with a round bottom bowl shape in projection. The guide surface 1301 formed at the bottom of the working fluid guiding structure 13 is an arc surface with high left and right ends and low middle opening in the second direction. The two working fluid guiding structures 13 are respectively set in the area between two adjacent rows of heating points 421 in the 3 rows of heating points 421. The two ends of any one working fluid guiding structure 13 in the first direction extend to the adjacent row of heating points 421. The two ends of any one working fluid guiding structure 13 in the second direction protrude two columns of heating points 421. The shape of the working fluid guiding structure 13 in this disclosure facilitates the formation of a guiding surface 1301 that guides the gaseous working fluid to both sides in the second direction of the heated zone 1101. Furthermore, the dimensions of the guiding surface 1301 in the second direction can be processed by adjusting the dimensions of the working fluid guiding structure 13 in the second direction, which facilitates the complete guidance of the rising gaseous working fluid to both sides in the second direction of the heated zone 1101 by the guiding surface 1301.

[0083] by Figure 8 Taking the disclosed eighth example, a heat source module 42 has three rows of heating points 421 in the first direction, and each row has two heating points 421 spaced apart along the second direction. There are two working fluid guiding structures 13, which are spaced apart in both the first and second directions. The working fluid guiding structure 13 is a strip-shaped plate structure with a flat-bottomed bowl shape. The bottom of the working fluid guiding structure 13 forms two opposing guiding surfaces 1301, which are connected by a flat bottom surface. The two working fluid guiding structures 13 are respectively set in the area between two adjacent rows of the three rows of heating points 421. The two ends of any one working fluid guiding structure 13 in the first direction extend to the adjacent upper and lower heating points 421, and the two ends of any one working fluid guiding structure 13 in the second direction protrude from both sides of the two rows of heating points 421. The shape of the working fluid guiding structure 13 in this disclosure facilitates the formation of two guiding surfaces 1301 that guide the gaseous working fluid to both sides in the second direction of the heated zone 1101. Furthermore, the dimensions of the guiding surfaces 1301 in the second direction can be processed by adjusting the dimensions of the working fluid guiding structure 13 in the second direction, which facilitates the complete guidance of the rising gaseous working fluid to both sides in the second direction of the heated zone 1101 by the guiding surfaces 1301.

[0084] by Figure 9As shown in the tenth disclosed embodiment, one heat source module 42 has 4 rows of heat points 421 in the first direction, each row has at least 1 heat point 421 spaced in the second direction, and the working medium guiding structure 13 is in a whole serpentine structure extending in the first direction, and the projection of the working medium guiding structure 13 on the first side wall 111 or the second side wall 114 is a serpentine strip; the side wall thereof downward in the first direction forms 3 guiding surfaces 1301, and the three guiding surfaces 1301 are respectively located in the regions between every two adjacent rows of heat points 421. In the present disclosure, the working medium guiding structure 13 is bent in the S shape in the first direction, and the multiple heated areas 1101 arranged in the first direction are separated to the two sides of the working medium guiding structure 13, and the shape of the working medium guiding structure 13 is convenient for forming multiple guiding surfaces 1301 guiding the gaseous working medium to the two sides of the heated area 1101 in the second direction, and the multiple guiding surfaces 1301 can be spaced in the first direction. It can be understood that in other not shown disclosed embodiments, one heat source module 42 can have 1 column of heat points 421 in the second direction, and each bending of the S-shaped working medium guiding structure 13 at least crosses one heat point 421 to ensure the guiding effect of the gaseous working medium at each heat point 421 located in the lower region.

[0085] In the present disclosure, the working medium guiding structure 13 is bent in the S shape in the first direction, and the multiple heated areas 1101 arranged in the first direction are separated to the two sides of the working medium guiding structure 13, and the shape of the working medium guiding structure 13 is convenient for forming multiple guiding surfaces 1301 guiding the gaseous working medium to the two sides of the heated area 1101 in the second direction, and the multiple guiding surfaces 1301 can be spaced in the first direction. It can be understood that in other not shown disclosed embodiments, one heat source module 42 can have 1 column of heat points 421 in the second direction, and each bending of the S-shaped working medium guiding structure 13 at least crosses one heat point 421 to ensure the guiding effect of the gaseous working medium at each heat point 421 located in the lower region. Figure 10 As shown in the tenth disclosed embodiment, one heat source module 42 has 4 rows of heat points 421 in the first direction, each row has at least 1 heat point 421 spaced in the second direction, and the working medium guiding structure 13 is in a whole serpentine structure extending in the first direction, and the projection of the working medium guiding structure 13 on the first side wall 111 or the second side wall 114 is a serpentine strip; the side wall thereof downward in the first direction forms 3 guiding surfaces 1301, and the three guiding surfaces 1301 are respectively located in the regions between every two adjacent rows of heat points 421. In the present disclosure, the working medium guiding structure 13 is bent in the S shape in the first direction, and the multiple heated areas 1101 arranged in the first direction are separated to the two sides of the working medium guiding structure 13, and the shape of the working medium guiding structure 13 is convenient for forming multiple guiding surfaces 1301 guiding the gaseous working medium to the two sides of the heated area 1101 in the second direction, and the multiple guiding surfaces 1301 can be spaced in the first direction. It can be understood that in other not shown disclosed embodiments, one heat source module 42 can have 1 column of heat points 421 in the second direction, and each bending of the S-shaped working medium guiding structure 13 at least crosses one heat point 421 to ensure the guiding effect of the gaseous working medium at each heat point 421 located in the lower region.

[0086] In the present disclosure, the working medium guiding structure 13 is bent in the S shape in the first direction, and the multiple heated areas 1101 arranged in the first direction are separated to the two sides of the working medium guiding structure 13, and the shape of the working medium guiding structure 13 is convenient for forming multiple guiding surfaces 1301 guiding the gaseous working medium to the two sides of the heated area 1101 in the second direction, and the multiple guiding surfaces 1301 can be spaced in the first direction. It can be understood that in other not shown disclosed embodiments, one heat source module 42 can have 1 column of heat points 421 in the second direction, and each bending of the S-shaped working medium guiding structure 13 at least crosses one heat point 421 to ensure the guiding effect of the gaseous working medium at each heat point 421 located in the lower region. Figure 11As shown in the disclosed eleventh aspect, a heat source module 42 has 2 rows of heat-emitting points 421 in the first direction, each row has 2 heat-emitting points 421 spaced apart in the second direction, the working medium guiding structure 13 is a strip-shaped plate structure projected as a straight line, the guiding surface 1301 formed at the bottom of the working medium guiding structure 13 is an inclined plane, the two ends of the working medium guiding structure 13 in the first direction respectively extend to the upper and lower sides of the two most distant heat-emitting points 421 in the first direction, the two ends of the working medium guiding structure 13 in the second direction respectively extend to the left and right sides of the two most distant heat-emitting points 421 in the second direction, and the working medium guiding structure 13 is arranged in the region between the two rows of heat-emitting points 421. The shape of the working medium guiding structure 13 in the present disclosure is more convenient for processing and can reduce the application cost compared with the structure having a curvature.

[0087] It can be understood that the arrangement and selection of the working medium guiding structure 13 are not limited to the above disclosure, and can be designed and adjusted according to the actual situation, which will not be exemplified here.

[0088] In a sixth aspect, as Figure 2 shown in the present disclosure, the evaporator 10 further comprises a heat-conducting diffusion rib 14 arranged in the evaporator body 11, one end of the heat-conducting diffusion rib 14 is connected with the first side wall 111, and the other end of the heat-conducting diffusion rib 14 extends away from the first side wall 111. In this way, the heat-conducting diffusion rib 14 can further conduct and diffuse heat, thereby improving the heat-dissipating effect of the evaporator 10 on the heat-emitting points 421 and the heat source module 42.

[0089] Preferably, as Figure 2 shown, the other end of the heat-conducting diffusion rib 14 extends to the inner surface of the other side wall opposite to the first side wall 111, so as to ensure the fixing effect of the heat-conducting diffusion rib 14 and the heat-conducting and diffusion effect of the heat-conducting diffusion rib 14, thereby further improving the heat-dissipating effect. It can be understood that the other end of the heat-conducting diffusion rib 14 can also extend to the inner surface of any inner wall of the other evaporator body 11 except the first side wall 111, which is not limited to the side wall opposite to the first side wall 111.

[0090] It can be understood that the heat-conducting diffusion rib 14 is a plurality of heat-conducting diffusion ribs, and at least part or all of the heat-conducting diffusion ribs 14 are located in the heated area 1101. In the present disclosure, the connection positions of all the heat-conducting diffusion ribs 14 with the first side wall 111 are located in the heated area 1101 or at least partially located in the heated area 1101, which is conducive to further improving the heat-conducting and diffusion effect.

[0091] In a seventh aspect, as Figure 2 and Figure 3As shown, the evaporator 10 also includes a capillary liquid return structure 12 disposed within the evaporator body 11. The capillary liquid return structure 12 is disposed on the inner surface of at least one sidewall of the evaporator body 11, including the first sidewall 111, and / or the outer surface of the heat-conducting diffusion ribs 14, and / or the surface of the working fluid guiding structure 13. The capillary liquid return structure 12 has pores for adsorbing liquid, so as to adsorb the liquid working fluid in the evaporator body 11 to the area of ​​the heated zone 1101 near the first sidewall 111 and its vicinity, thereby preventing dry burning in a part of the heated zone 1101. The working fluid guiding structure 13 is disposed on the first sidewall 111, and / or, the working fluid guiding structure 13 is disposed on the capillary liquid return structure 12. It should be noted that, in this disclosure, one end of the working fluid guiding structure 13 near the heating point 421 or the heat source module 42 passes through the capillary liquid return structure 12 and is disposed on the first sidewall 111. It is understood that in other disclosures not shown, the end of the working fluid guiding structure 13 near the heating point 421 or the heat source module 42 may be set on the capillary return structure 12 or simultaneously on the capillary return structure 12 and the first sidewall 111, and the other end of the working fluid guiding structure 13 away from the heat source module 42 may be extended according to the actual situation, which will not be listed here.

[0092] In this disclosure, the capillary return structure 12 can be disposed in the area projected onto the first sidewall 111 of the heated zone 1101. Figure 2 and Figure 3 The capillary liquid return structure is also set on the surface of the heat-conducting diffusion ribs 14. Through the capillary liquid return structure 12, the liquid working medium inside the evaporator body 11 can be adsorbed to the heated zone 1101 and the area near the heated zone 1101, so as to continuously provide liquid working medium to the heated zone 1101 and the area near the heated zone 1101, which can avoid the situation of dry burning due to lack of liquid. At the same time, it is beneficial to improve the liquid return efficiency of the liquid working medium in the evaporator body 11 and the deheating effect of the evaporator 10 on the heating point 421 or the heat source module 42.

[0093] Preferably, the capillary return structure 12 on the heat-conducting and diffusing rib 14 is integrally formed with the capillary return structure 12 on the heated zone 1101. This arrangement allows the heat-conducting and diffusing rib 14 to primarily conduct heat to the heated zone 1101, helping to prevent the zone from overheating and becoming dry-burning due to insufficient liquid. Simultaneously, the covering of the capillary return structure 12 also helps to prevent dry-burning due to insufficient liquid at the heat-conducting and diffusing rib 14.

[0094] It can be understood that the extension of the heat-conducting diffusion rib 14 can be adjusted according to actual conditions, and can be one or a combination of a straight line, a broken line, a meandering line, an arc, etc. The distribution of the plurality of heat-conducting diffusion ribs 14 can also be adjusted according to actual conditions, and can be distributed in a radial manner or in a flush manner, etc.

[0095] Preferably, each heat-conducting diffusion rib 14 is provided with a capillary liquid return structure 12.

[0096] Specifically, the at least one heat-conducting diffusion rib 14 is provided with a plurality of heat-conducting protrusions 141, as shown in the fourth disclosure, in the present disclosure, the plurality of heat-conducting diffusion ribs 14 located in the central area are each provided with a heat-conducting protrusion 141, so as to further expand the surface area of the heat-conducting diffusion rib 14, and thereby improve the conduction and dispersion effect of heat. It can be understood that the arrangement of the heat-conducting protrusion 141 can be designed according to actual conditions, and examples are not given here. Figure 4

[0097] It should be noted that the capillary liquid return structure 12 has a gap inside for adsorbing liquid, and the capillary liquid return structure 12 is one or a combination of sintered powder, groove, and wire mesh, so as to design the capillary liquid return structure 12 according to actual conditions and ensure the adsorption effect of the capillary liquid return structure 12 on the liquid-phase working medium. The groove can be a dot-shaped pit, a linear groove, a Y-shaped groove, a C-shaped groove, etc., the wire mesh can be a wire mesh-shaped protrusion or a wire mesh-shaped groove, etc., and examples are not given here.

[0098] The eighth aspect, as shown in the fourth disclosure, the outer surface of the first side wall 111 has a groove recessed inwardly, and the groove is used for limiting installation of the heat source module 42 including the heat generation point 421. In this way, the contact area of the heat source module 42 and the first side wall 111 is improved, thereby expanding the heat exchange area, and the heat dissipation effect of the evaporator 10 on the heat generation point 421 and the heat source module 42 is further improved. It can be understood that the plurality of side walls of the groove can also serve as heat-conducting inner walls, and the area corresponding to the heated area 1101 in the present disclosure is larger than that of the heated area 1101 in the first disclosure. Figure 4

[0099] ​​In the case where the heat source module 42 includes multiple heat points 421 and the heat source module 42 is multiple, multiple sets of heated areas 1101 are formed inside the evaporator body 11, and the working medium guiding structure 13 can be one, in which case the working medium guiding structure 13 is arranged simultaneously corresponding to at least one of the multiple heat source modules 42; or the working medium guiding structure 13 can be multiple, and the multiple working medium guiding structures 13 are arranged one by one corresponding to the multiple heat source modules 42. Or, the working medium guiding structure 13 can be multiple, and one working medium guiding structure 13 is arranged corresponding to at least two heat source modules 42. Or, some heat source modules 42 correspond to working medium guiding structures 13, or some heat source modules 42 do not correspond to working medium guiding structures 13, i.e., heat source modules 42 with small heat generation can not be arranged with working medium guiding structures 13. The capillary liquid return structure 12 is the same. This is conducive to reducing the processing and design cost of the working medium guiding structure 13 and the capillary liquid return structure 12 while ensuring the heat dissipation effect of the heat source module 42. Specifically, the number of working medium guiding structures 13 corresponding to the heated areas 1101 in each heat source module 42 can be set according to actual conditions.

[0100] Similarly, the working medium guiding structure 13 can be multiple, and the working medium guiding structure 13 is arranged one by one corresponding to one heat point 421 respectively, or one working medium guiding structure 13 is arranged corresponding to two or more heat points 421; or some heat points 421 do not have corresponding working medium guiding structures 13.

[0101] As shown in the second disclosure shown in Figure 13 The heat source module 42 is four, each heat source module 42 has six heated areas 1101 distributed along the first direction and the second direction, the working medium guiding structure 13 is multiple, and multiple working medium guiding structures 13 are arranged corresponding to any heat source module 42. For each heat source module 42, the arrangement of the corresponding working medium guiding structure 13 is similar to Figure 1 Here, it will not be repeated. In this way, it is conducive to ensuring the exhaust capacity at each heat source module 42, and further ensuring the heat dissipation effect of the heat source module 42.

[0102] As shown in the second disclosure shown in Figure 14In the disclosed twelve, each heat source module 42 has three rows of heating points 421 in the first direction, and each row has two heating points 421 spaced apart along the second direction. Each heating point corresponds to a heated area. There are two working fluid guiding structures 13, which are spaced apart in both the first and second directions. The working fluid guiding structure 13 is a strip-shaped plate structure with a flat bottom and a bowl shape projected onto the first sidewall 111 or the second sidewall 114. The bottom surface of the working fluid guiding structure 13 and the bottom surfaces of the upward-curving sides on both sides of the bottom together form a guiding surface 1301. The two working fluid guiding structures 13 are respectively arranged in the area between two adjacent rows of the three rows of heating points 421. The two ends of any one working fluid guiding structure 13 in the first direction extend to the adjacent upper and lower heating points 421, and the two ends of any one working fluid guiding structure 13 in the second direction protrude from both sides of the two rows of heating points 421. The shape of the working fluid guiding structure 13 in this disclosure facilitates the formation of two guiding surfaces 1301 that guide the gaseous working fluid to both sides in the second direction of the heated zone 1101. Furthermore, the dimensions of the guiding surfaces 1301 in the second direction can be processed by adjusting the dimensions of the working fluid guiding structure 13 in the second direction, which facilitates the complete guidance of the rising gaseous working fluid to both sides in the second direction of the heated zone 1101 by the guiding surfaces 1301.

[0103] like Figure 15 In the disclosed thirteen, there are four heat source modules 42, each heat source module 42 having six heating zones 1101 spaced apart along a first direction and a second direction. There are multiple working fluid guiding structures 13, with any one working fluid guiding structure 13 corresponding to two heat source modules 42. The shape of the working fluid guiding structure 13 is similar to... Figure 14 The shapes are the same, the only difference being that the two adjacent heat source modules 42 share the working fluid guiding structure 13.

[0104] like Figure 16 In the fourteenth disclosure shown, there are five heat source modules 42, each heat source module 42 has six heating zones 1101 distributed at intervals along the first and second directions, and multiple working fluid guiding structures 13. Any one working fluid guiding structure 13 is set for two heat source modules 42. The difference is that the smaller heat source module 42 located in the middle does not have a working fluid guiding structure 13.

[0105] It should be noted that, Figures 14-16 The projection of the heated zone 1101 on the first sidewall 111 in the disclosed diagram is the same as... Figure 13 As shown in the public disclosure, or, Figures 14-16 The projection of the heated zone 1101 onto the first sidewall 111 in the disclosed diagram is Figure 13 The heated zone 1101 in the disclosed diagram is scaled proportionally.

[0106] Ninthly, another disclosure of this utility model provides a thermosiphon heat exchanger 44, which includes a condenser 20, a connecting pipe 30, and the aforementioned evaporator 10. A portion of the condenser 20 is positioned higher than the evaporator 10; for example, the entire condenser 20 is positioned higher than the evaporator 10. Alternatively, half of the condenser 20 is projected onto a plane formed by the first and second directions, within the projection area of ​​the evaporator 10 on the same plane. The bottom of the evaporator body 11 has a liquid phase inlet 113, and the condenser 20 has a liquid phase outlet and a gas phase inlet.
