Referring to fig. 1-3, there are shown an exploded view and a perspective view of another view of the evaporator structure of the present invention, wherein the evaporator structure includes a heat exchange assembly 1, a heat conductive housing 2, and an upper cover 3.
Wherein the heat exchange assembly 1 can be formed integrally or assembled, the heat exchange assembly 1 can be divided into a steam zone 11 and a water inlet zone 12, the area of the steam zone 11 is larger than that of the water inlet zone 12, a separation wall 13 is arranged between the steam zone 11 and the water inlet zone 12, a plurality of parallel transverse passages 14 penetrating up and down are formed inside the heat exchange assembly 1, a longitudinal water inlet passage 15 is arranged above the water inlet zone 12 and close to the center, the length of the longitudinal water inlet passage 15 is from one side to the separation wall 13, a plurality of longitudinal steam passages 16 (in the embodiment, one passage and three passages are arranged on the longitudinal water inlet passage 15, the longitudinal steam passage 16 is from one side to the separation wall 13, so that the length of the longitudinal steam passage 16 is larger than that of the longitudinal water inlet passage 15, the longitudinal water inlet channel 15 and the longitudinal steam channel 16 are not communicated with each other by the arrangement of the blocking wall 13, and the longitudinal water inlet channel 15 and the longitudinal steam channel 16 are arranged perpendicular to the transverse channel 14.
A first longitudinal cooling fluid channel 17 is respectively arranged below the heat exchange component 1 and close to the two side edges, the first longitudinal cooling fluid channel 17 penetrates through the vapor zone 11, the water inlet zone 12 and the lower portion of the baffle wall 13, so that the first longitudinal cooling fluid channel 17 penetrates through both end edges of the heat exchange assembly 1, and a plurality of second longitudinal cooling fluid passages 18 are provided below and near the center of the vapor zone 11, the length of the second longitudinal cooling fluid passage 18 is from one side to the baffle wall 13, so that the length of the second longitudinal cooling fluid passage 18 is the same as that of the longitudinal steam passage 16, and the longitudinal water inlet upper passage 15 is also blocked by the baffle wall 13, but not to the water inlet region 12 (in this embodiment, four cooling fluid passages 18 and two cooling fluid passages 17 are provided), and the positions of the cooling fluid passages 18 and the vapor passages 16 are staggered.
Wherein the heat conducting shell 2 is internally used for placing the heat exchange assembly 1.
The upper cover 3 is used for covering the upper portion of the heat conducting housing 2, a steam outlet 31 and a water inlet 32 are respectively formed on the upper cover 3, the steam outlet 31 corresponds to the upper portion of one of the longitudinal steam channels 16, and the water inlet 32 corresponds to the upper portion of one of the longitudinal water inlet channels 15.
In general, each of the heat-conducting housings 2 includes a predetermined amount of cooling fluid a and vapor B, as shown in fig. 4 and 5, when the heat-conducting housing 2 is used, the bottom surface of the heat-conducting housing 2 is fixed on a heat source generating device 4, the heat source generating device 4 corresponds to the vapor region of the heat exchanging assembly 1, and a heat dissipating fin 5, a vapor through pipe 6 and a cooling fluid through pipe 7 are installed on the upper cover 3, the vapor through pipe 6 and the cooling fluid through pipe are connected to a condenser 8, when the heat source generating device 4 generates a heat source, the heat energy generated by the heat source generating device 4 can be guided into the inner generating region of the heat-conducting housing 2 to the vapor region 11 of the heat exchanging assembly 1, when the heat source received by the heat-conducting housing 2 reaches a predetermined evaporation temperature, the cooling fluid a in the transverse channel 14 and the second longitudinal cooling fluid channel 18 of the heat exchanging assembly 1 is evaporated into the vapor B due to high temperature, the vapor B is guided by the transverse channel 14, rises and converges to the plurality of longitudinal vapor channels 16, and is decompressed by the plurality of longitudinal vapor channels 16, so as to prevent the internal pressure of the heat-conducting shell 2 from being too concentrated, and the vapor B is transmitted to the condenser 8 through the vapor outlet 31 and the vapor through pipe 6, and is converted into the cooling fluid a after being cooled by the condenser 8, and because the cooling fluid a is evaporated into a gaseous state and enters the condenser 8, the pressure in the heat exchange assembly 1 becomes small, so that the cooling fluid a entering the condenser 8 becomes the cooling fluid a, and then flows back to the heat exchange assembly 1 of the evaporator through the cooling fluid through pipe 7.
Then, as shown in fig. 4, 6 and 7, the cooling fluid a flows back to enter each transverse channel 14 through the water inlet 32 and the longitudinal water inlet upper channel 15 in sequence, because the second longitudinal cooling fluid channel 18 is not communicated with the longitudinal water inlet upper channel 15, when the cooling fluid a flows in through the longitudinal water inlet upper channel 15, the cooling fluid a flows in both sides direction through the transverse channels 14 respectively, and then flows longitudinally through the first longitudinal cooling fluid channel 17, and then flows towards the second longitudinal cooling fluid channel 18 through the transverse channels 14, through the arrangement of the second longitudinal cooling fluid channel 18, the cooling fluid a can flow towards the transverse position and the longitudinal position of the heat source area generated by the heat source generating device 4, so as to transfer a large amount of cooling fluid a to the heat source area, and avoid too small amount of cooling fluid a, therefore, through the arrangement of the first longitudinal cooling fluid channel 17 and the second longitudinal cooling fluid channel 18, the cooling fluid a can be brought into the central heat source area from the outermost side, so that each position of the heat exchange assembly can be contacted with the cooling fluid a to achieve the purpose of heat dissipation, and when the cooling fluid a enters the heat source area, the cooling fluid a is heated again and evaporated into a vapor body B, and the vapor body B can upwards enter the through pipe 6 to the condenser 8 through the vapor channel 13 and the vapor outlet 31 in sequence, so as to circulate continuously, thereby achieving the purpose of circulating heat dissipation.
Therefore, it can be seen that the cooling fluid a is heated and evaporated in the vapor region 11 of the heat exchange assembly 1 to form the vapor B, and then the heat is separated and transferred to the condenser 8, and the cooling fluid a is condensed and condensed to form the cooling fluid a and then flows back to the water inlet region 12 of the heat exchange assembly 1, and since the water inlet region 12 and the vapor region 11 include a partition wall 13 therebetween, the cooling fluid a and the vapor B can respectively act in the heat exchange assembly 1, thereby achieving the effects of gas-liquid separation, cold-heat alternation and automatic circulation.
In addition, as shown in fig. 5, since the second longitudinal cooling fluid channel 18 is disposed at a position different from the vapor channel 13, the area of the cooling fluid a flowing through the transverse channels 14 can be increased, thereby increasing the heat dissipation efficiency.
The evaporator structure provided by the invention particularly improves the configuration of a cooling fluid channel in the heat exchange assembly so as to improve the path of the cooling fluid flowing in the heat exchange assembly, thereby improving the overall heat dissipation benefit, and has the following advantages:
1. the heat exchange assembly provided by the invention is particularly provided with the water inlet area and the steam area, and only the first longitudinal cooling fluid channel can be communicated with the water inlet area and the steam area, so that cooling fluid is forced to flow towards two sides after entering the longitudinal water inlet upper channel, and then the cooling fluid is guided to the second longitudinal cooling fluid channel through the transverse channel to flow back to the steam area of the heat exchange assembly, so that the cooling fluid can uniformly flow through the water inlet area and the steam area of the whole heat exchange assembly, and the cooling fluid flows and circulates in the heat exchange assembly in the largest contact area, thereby having the advantage of whole-area heat dissipation of improving the whole heat dissipation benefit.
2. The heat exchange assembly provided by the invention is characterized in that a plurality of second longitudinal cooling fluid channels are arranged at the lower position of the steam area, and the distance between the channels is shortened due to the increase of the number, so that the water level of the cooling fluid between the second longitudinal cooling fluid channels can be balanced, the condition that the water level at a specific position is too low to cause high temperature at a local position is avoided, and in addition, the pressure in the heat exchange assembly can be averaged.
It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
