DETAILED DESCRIPTION

[0020] The embodiment of the present application discloses a heater and a liquid cooling module to improve heating uniformity, thereby ensuring heating accuracy and temperature control accuracy of the system.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] In some embodiments, see Figure 1-Figure 6 The heater provided in the present application includes a shell 1, a heating module 2 and a flow equalizer 3. Among them, the shell 1 forms a heating chamber 11, and the shell 1 is provided with an inlet 12 and a first outlet 13a, and the inlet 12 and the first outlet 13a are respectively connected to the heating chamber 11. The shape of the shell 1 can be set as needed, and is not specifically limited here. A heating chamber 11 is formed inside the shell 1, and the flow channel area of ​​the heating chamber 11 can be set as needed. The inlet 12 is the medium inlet, and the first outlet 13a is the first outlet 13a of the medium. The inlet 12 and the first outlet 13a can be connected to other components of the system respectively. The positions of the inlet 12 and the first outlet 13a can be set accordingly according to the shape of the shell 1 and the connection orientation of the heater and other components. Exemplarily, the inlet 12 and the first outlet 13a are respectively arranged at opposite ends of the shell 1, so that the medium can flow better in the heater and be fully heated. The medium can be either a liquid or a gas as needed.

[0023] The heating module 2 includes a plurality of heating elements 21 arranged in the heating chamber 11, and the plurality of heating elements 21 are arranged in sequence, and a first interval 22 is provided between adjacent heating elements 21. It should be noted that the term "multiple" in the present application refers to two or more. The heating element 21 is used to heat the medium in the heating chamber 11, and its types include but are not limited to resistance heating, electromagnetic heating, etc. The specific structure and working principle can refer to the conventional heating element 21, which will not be repeated here. The plurality of heating elements 21 are spaced apart in sequence, and the intervals between the heating elements 21 are respectively recorded as first intervals 22. It can be understood that the sizes of the first intervals 22 can be the same or different.

[0024] The flow equalizer 3 is arranged in the heating chamber 11, and the flow equalizer 3 is formed with a plurality of shunt channels 31 for shunting the fluid in the heating chamber 11, and each shunt channel 31 is respectively connected to the corresponding first interval 22, and one end of each shunt channel 31 is close to the inlet 12. It can be understood that the flow equalizer 3 can be used as an independent component and arranged in the shell 1, such as being arranged in the shell 1 by a conventional fixing method. Alternatively, the flow equalizer 3 and the shell 1 can also be an integrated structure. The flow equalizer 3 forms a plurality of shunt channels 31, and one end of each shunt channel 31 is close to the inlet 12. Exemplarily, the distance from one end of each shunt channel 31 to the inlet 12 is less than a preset value, and the preset value ranges from 0.1 to 10 cm. The shunt channel 31 extends from one end close to the inlet 12 to one end of the first outlet 13a, and corresponds to the first interval 22. The number of shunt channels 31 and the number of heating elements 21 may be the same or different. In one embodiment, the number of the diversion channels 31 is the same as the number of the first intervals 22 and corresponds one to one; in another embodiment, the number of the diversion channels 31 is less than the number of the first intervals 22, and each diversion channel 31 corresponds to a corresponding first interval 22.

[0025] By using the heater provided by the present application, the medium enters the heating chamber 11 from the inlet 12, enters each flow divider channel 31 under the flow divider effect of the flow equalizer 3, and can enter the first interval 22 between the heating elements 21 along the flow divider channel 31, and then be discharged through the first outlet 13a. By using this heater, the medium can be divided by the flow equalizer 3 and correspond to each first interval 22 during the process of flowing through the heating chamber 11 and being heated by the heating element 21, so that the flow rate of the medium flowing through each first interval 22 can be adjusted, the uniformity of heating the medium is improved, and the heating efficiency and heating accuracy are improved.

[0026] In some embodiments, the plurality of heating elements 21 are evenly spaced and distributed, and the widths of the first intervals 22 are equal. The size of the first intervals 22 can be set accordingly according to the width of the heating chamber 11 and the number and width of the heating elements 21, which are not specifically limited here. As set above, the flow rate of the medium flowing through each first interval 22 is substantially the same, further improving the uniformity of heating the medium.

[0027] In some embodiments, the housing 1 includes a first wall 14, a second wall 15 and a third wall 16, the first wall 14 is opposite to the second wall 15, the inlet 12 is arranged on the first wall 14, the first outlet 13a is arranged on the second wall 15, the third wall 16 is connected between the first wall 14 and the second wall 15, one end of the heating element 21 is spaced from the first wall 14, and the other end adjacent to the heating element 21 is spaced from the third wall 16. That is, the space of the heating chamber 11 is relatively large, and the overall space occupied by each heating element 21 is relatively small, and there is a gap between at least the first wall 14 and the second wall 15 of the housing 1, and the size of the gap is determined according to the size of the heating element 21. In order to meet the requirements of the flow channel area in the housing 1, the heating chamber 11 is usually relatively large. If the heating element 21 is designed with a corresponding size, on the one hand, the cost is relatively high, and on the other hand, the overall weight of the heater is relatively heavy. Therefore, the above arrangement can effectively save costs and control product weight.

[0028] In order to better play the role of diversion, the diversion channel 31 includes a diversion section 311 and a guide section 312. The guide section 312 is located between the heating module 2 and the third wall 16, and the diversion section 311 is located between the heating module 2 and the first wall 14. One end of the diversion section 311 is opposite to the inlet 12, and part of the other end is connected to the guide section 312 and part is connected to the first interval 22. The guide section 312 is arranged at one end of the heating module 2 facing the third wall 16, and the diversion section 311 is arranged between the side of the heating module 2 close to the inlet 12 and the inlet 12. The diversion section 311 is arranged close to the inlet 12, and mainly plays the role of diverting the medium entering the heating chamber 11. It can be understood that one end of the diversion section 311 is opposite to the inlet 12, which means that one end of the diversion section 311 is completely opposite to the inlet 12 or partially opposite to the inlet 12. The guide section 312 is disposed between the heating module 2 and the housing 1 , and mainly serves to guide the medium after being diverted by the diversion section 311 .

[0029] For example, Figure 4 In the figure, in the left-right direction, the end of the heating element 21 is spaced a certain distance from the third wall 16, and the guide section 312 is arranged within the space so that the medium is connected along the guide section 312. The height of the diverter section 311 in the first direction is greater than the height of the guide section 312 in the first direction, that is, part of the diverter section 311 is connected to the first interval 22, and the remaining part is connected to the guide section 312, wherein the first direction is perpendicular to the medium inlet and outlet direction. For ease of explanation, Figure 4Taking the first direction along the left and right direction as an example, the left part of the diverter section 311 is connected to the guide section 312, and the right part is connected to the first interval 22. The diverter section 311 of each diverter channel 31 corresponds to each first interval 22 from the side of the heating module 2 close to the inlet 12, and the guide section 312 of each diverter channel 31 corresponds to each first interval 22 from the end of the heating module 2 close to the third wall 16. When the diverter channel 31 adopts the above arrangement, when the volume of the heating chamber 11 is significantly larger than the heating module 2, the medium entering the inlet 12 can be evenly diverted and the flow direction of the medium can be guided, so that the medium flows evenly in the heating chamber 11, thereby improving the uniformity of heating the medium and improving the heating efficiency.

[0030] In some embodiments, the guide section 312 extends in a straight line, and each guide section 312 is parallel. It is understandable that the straight extension direction of the guide section 312 is the same as the extension direction of the first interval 22. By extending the guide section 312 in a straight line and arranging it in parallel, the flow resistance is reduced. Exemplarily, a plurality of heating elements 21 are arranged in parallel, and the heating element 21 can be a heating plate. The first intervals 22 between each adjacent heating plate are equal, and the width of the first interval 22 from one end close to the diverter section 311 to the other end remains unchanged. The widths of the guide sections 312 are equal, that is, the width of the guide section 312 from one end connected to the diverter section 311 to the other end remains unchanged, and the widths of each guide section 312 are equal, which further ensures heating uniformity.

[0031] In some embodiments, the width of the diverter section 311 gradually increases from the end close to the inlet 12 to the end connected to the guide section 312, and the width of the end connected to the guide section 312 is the same as the width of the corresponding guide section 312. Since the width of the inlet 12 is usually smaller than the width inside the heating chamber 11, that is, the medium flows into the heating chamber 11 with an increased flow channel area through the inlet 12. Therefore, the diverter section 311 is configured to have a smaller width at one end close to the inlet 12 and a larger width at the other end, so that each diverter section 311 is respectively opposite to the inlet 12, so as to play a good diversion role and guide the medium to each guide section 312 and each first interval 22.

[0032] In some embodiments, along the arrangement direction of each heating element 21, there is a second interval between the two heating elements 21 located at the edge and the shell 1, and edge channels 4 are formed between the corresponding two sides of the flow equalizer 3 and the shell 1, one end of the edge channel 4 is opposite to the inlet 12, and the edge channel 4 corresponds to and communicates with each second interval. It can be understood that one end of the edge channel 4 is opposite to the inlet 12, which means that one end of the edge channel 4 is completely opposite to the inlet 12 or partially opposite to the inlet 12. For example, please refer to Figure 6 , Figure 6An edge flow channel 4 is formed between the left side of the flow equalizer 3 and the shell 1, and an edge flow channel 4 is formed between the right side of the flow equalizer 3 and the shell 1. Correspondingly, there is a second interval between the leftmost heating element 21 and the shell 1, and there is a second interval between the rightmost heating element 21 and the shell 1. The second interval on the left side corresponds to and is connected to the edge flow channel 4, and the second interval on the right side corresponds to and is connected to the edge flow channel 4. As set above, the two sides of the flow equalizer 3 can also play a guiding role, further improving the uniformity of the medium flow.

[0033] In some embodiments, the flow equalizer 3 includes a plurality of guide plates 32, and the plurality of guide plates 32 are spaced apart to form a diversion channel 31 between adjacent guide plates 32. The guide plates 32 are provided to separate the diversion channel 31 from the heating chamber 11. The guide plates 32 have a simple structure, are easy to process, and have low cost. The guide plates 32 are provided on the inner wall of the shell 1, and can be integrally formed with the shell 1, or can be fixed to the inner wall of the shell 1 by bonding, clamping, or the like. When the guide plates 32 and the shell 1 adopt a split structure, illustratively, the guide plates 32 are detachably connected to the shell 1, so as to facilitate the adjustment of the shape and size of the guide plates 32 as needed, or the maintenance of the guide plates 32. In other embodiments, the flow equalizer 3 can also adopt a block structure, and form the diversion channel 31 by grooving the block structure.

[0034] In the case where the diverter channel 31 includes a guide section 312 and a diverter section 311, the guide plate 32 includes a guide plate section 322 and a diverter section 321, the guide plate section 322 is located between the heating module 2 and the third wall surface 16, the diverter section 321 is located between the heating module 2 and the first wall surface 14, the diverter section 311 of the diverter channel 31 is formed between adjacent diverter sections 321, and the guide section 312 of the diverter channel 31 is formed between adjacent diverter sections 322. Exemplarily, each guide plate section 322 is respectively arranged opposite to the end surface of the corresponding heating element 21, and the end of each diverter section 321 away from the inlet 12 is respectively opposite to the side surface of the corresponding heating element 21.

[0035] In some embodiments, the end of the guide plate 32 close to the inlet 12 is in a sharp angle shape with a reduced width. That is, the width of the guide plate 32 gradually decreases in the direction close to the inlet 12, so that the end of the guide plate 32 is in a sharp angle shape. Exemplarily, the end of the guide plate 32 close to the inlet 12 is an edge. In this way, the contact area between the guide plate 32 and the medium is small, which significantly reduces the saved flow resistance.

[0036] In some embodiments, the housing 1 is formed with a straight channel 121, one end of which is connected to the inlet 12, and the other end is connected to the heating chamber 11. The straight channel 121 forms a straight channel for the flow of the medium. Exemplarily, the inlet 12 is connected to the outlet of the liquid pump 20, and the liquid at the outlet of the liquid pump 20 enters the heating chamber 11 through the inlet 12. Through the setting of the straight channel 121, the straight channel 121 can play a role in stabilizing the flow when the liquid passes. The specific length of the straight channel 121 can be set accordingly according to the length requirement for stabilizing the flow, and is not specifically limited here.

[0037] In some embodiments, the housing 1 includes a bottom shell 17 and a cover 18. The bottom shell 17 is provided with a receiving groove 171, and the two ends of the bottom shell 17 are respectively provided with an inlet 12 and a first outlet 13a; the cover 18 is sealed and connected to the bottom shell 17, and forms a heating chamber 11 with the bottom shell 17, and the heating module 2 is arranged on the cover 18. The housing 1 adopts a split structural design, which is convenient for the installation and maintenance of various internal components. During assembly, the cover 18 is installed on the top opening of the bottom shell 17 and is sealed and connected to the bottom shell 17, and the heating element 21 of the heating module 2 arranged on the cover 18 is inserted into the receiving groove 171. The sealing method of the cover 18 and the bottom shell 17 includes but is not limited to a sealing ring, a labyrinth seal, etc. Exemplarily, a first sealing ring 19a is squeezed between the cover 18 and the bottom shell 17 to achieve an effective seal between the two.

[0038] In some embodiments, see Figure 1-Figure 7 The shell 1 is also provided with a second outlet 13b, one of the first outlet 13a and the second outlet 13b is the outlet of the first heat exchanger, and the other is the outlet of the valve. The inlet 12 of the heater is used to connect with the inlet of the liquid pump 20, the outlet of the first heat exchanger is used to connect with the inlet of the first heat exchanger 30, the outlet of the valve is used to connect with the valve 40, the valve 40 is connected to the second heat exchanger, and the outlet of the first heat exchanger and the outlet of the second heat exchanger are respectively connected to the load end. The liquid pump 20 drives the liquid to circulate between the first heat exchanger 30 and the load, the second heat exchanger is connected in parallel with the first heat exchanger 30, the liquid pump 20 can also be used to drive the liquid to circulate between the second heat exchanger and the load, and the valve 40 can be used to adjust the on-off between the second heat exchanger and the liquid pump 20. The first heat exchanger 30 is used to realize the heat exchange between the liquid from the load and the liquid at the condenser end. The second heat exchanger can be a dry cooler. As set above, the heater can be integrated with different components, and there is no need to install corresponding pipes when the system is assembled on site, which reduces the number of on-site assembly components and simplifies the assembly process. It reduces the system coolant leakage points, reduces the difficulty of device maintenance, and reduces the overall space occupancy.

[0039] In some embodiments, the inlet 12, the first outlet 13a, and the second outlet 13b of the housing 1 may be provided with a second sealing ring 19b respectively to seal with the corresponding liquid pump 20, the first heat exchanger 30, and the heater.

Since the liquid cooling module adopts the heater in the above embodiment, please refer to the above embodiment for the beneficial effects of the liquid cooling module.
