It may be appreciated that, in order to improve the heat dissipation performance of the electronic control heat dissipation structure 100, the heat dissipation member 1, the refrigerant pipe 2 and the cover plate 3 are all made of metal materials, and the metal materials are copper or aluminum, because the metal has a higher heat conduction performance, the metal materials are used to help provide the heat dissipation performance of the electronic control heat dissipation structure 100.
It should be noted that the heat conducting side 12 and the electric control element may be in various heat conducting forms, the heat conducting side 12 and the electric control element may be in direct contact, or may be in indirect contact through a heat conducting medium, for example, heat conducting paste or the like, which is not limited in the invention, in addition, the refrigerant tube 2 has flowing refrigerant, the electric control heat dissipation structure 100 absorbs and takes away heat transferred by the heat dissipation member 1 through the flowing refrigerant in the refrigerant tube 2, so as to achieve the cooling purpose, and it is understood that the refrigerant in the refrigerant tube 2 may be water or cooling liquid or the like.
It should be noted that, there are various connection modes of the cover plate 3 and the heat dissipation member 1, the cover plate 3 may be welded with the heat dissipation member 1, or may be fastened by a buckle, or may be other modes, which is not limited in the present invention, further, in order to facilitate the assembly and disassembly of the refrigerant pipe 2 and the maintenance of the electric control heat dissipation structure 100, the cover plate 3 is detachably connected to the base, specifically, the cover plate 3 is provided with a through hole, the heat dissipation member is provided with a fixing hole corresponding to the through hole, and the electric control heat dissipation structure 100 further includes a fixing bolt, and the fixing bolt is inserted into the through hole and the fixing hole, so that the assembly and disassembly are convenient, and the fixing is firm.
Further, in order to facilitate the disassembly of the cover plate 3, in an embodiment, the side wall of the mounting groove 13 is provided with a disassembly opening, so that the fingers of an operator can conveniently extend into the disassembly opening, the cover plate 3 is disassembled from the side edge of the cover plate 3, and further, the disassembly opening is provided with a plurality of disassembly openings, and the disassembly openings are formed in two opposite side walls of the mounting groove 13, so that the operator can forcefully clamp the cover plate 3, and the cover plate 3 is conveniently disassembled.
Since the larger the contact area between the refrigerant tube 2 and the heat dissipating member 1 is, the more heat the refrigerant tube 2 exchanges with the heat dissipating member 1, in this embodiment, referring to fig. 2, the outer diameter of the refrigerant tube 2 is D1, the groove depth of the first accommodating groove 14 is H1, where H1 is greater than or equal to d1×50%, so as to enable most of the refrigerant tube 2 to be embedded into the heat dissipating member 1, so as to ensure that the refrigerant tube 2 and the heat dissipating member 1 maintain a sufficient contact area, so that the refrigerant tube 2 and the heat dissipating member 1 can exchange more heat, thereby improving the heat exchanging efficiency of the heat dissipating member 1 and the refrigerant tube 2, so that the refrigerant tube 2 can take away more heat, and further improving the heat dissipating effect of the electronic control heat dissipating structure 100, preferably, H1 is greater than or equal to d1×70%.
Since the deeper the second accommodating groove 31, the deeper the refrigerant tube 2 is embedded into the cover plate 3, the more the refrigerant tube 2 is embedded into the cover plate 3, resulting in less contact between the refrigerant tube 2 and the heat sink 1, and lower heat exchange efficiency between the refrigerant tube 2 and the heat sink 1, in this embodiment, referring to fig. 2, the second accommodating groove 31 has a groove depth H2, wherein H2 is equal to or less than d1×30%, and is configured such that most of the refrigerant tube 2 is embedded into the heat sink 1, thereby facilitating heat exchange between the refrigerant tube 2 and the heat sink 1.
Although the larger the contact area between the refrigerant pipe 2 and the heat dissipation member 1 is, the deeper the refrigerant pipe 2 is embedded into the heat dissipation member 1, which results in the more difficult the assembly and disassembly of the refrigerant pipe 2, so that the refrigerant pipe 2 is conveniently installed in the first accommodating groove 14, in this embodiment, the notch of the first accommodating groove 14 is in a horn shape, and further, the notch of the first accommodating groove 14 is gradually widened outwards, so that the notch width of the first accommodating groove 14 is larger than the width of the bottom of the first accommodating groove 14, thereby facilitating the installation of the refrigerant pipe 2 in the first accommodating groove 14.
In order to make the refrigerant pipe 2 closely adhere to the heat dissipation member 1, specifically, in this embodiment, the aperture of the mounting hole is D2, where D1 is greater than or equal to D2, and the mounting hole is set so that the mounting hole is smaller than or equal to the outer diameter of the refrigerant pipe 2, so that the refrigerant pipe 2 is tightly adhered to the heat dissipation member 1 downward under the cover of the cover plate 3, so as to prevent the refrigerant pipe 2 from separating from the heat dissipation member 1, and avoid affecting heat exchange between the heat dissipation member 1 and the refrigerant pipe 2.
Because gaps exist between the refrigerant pipe 2 and the mounting hole and between the mounting groove 13 and the cover plate 3 under the condition that H1 is more than or equal to D1×50%, in order to accelerate heat transfer, heat exchange between the heat dissipation element 1 and the refrigerant pipe 2 is avoided being influenced, in one embodiment, the heat dissipation paste is filled in the mounting groove 13 and is used for filling the heat dissipation paste between the heat dissipation element 1 and the cover plate 3, gaps between the heat dissipation element 1 and the cover plate 3 are avoided, contact area between the heat dissipation element 1 and the cover plate 3 is increased, and heat transfer effect is improved.
In another embodiment, the mounting hole is filled with a heat dissipating paste, so that the heat dissipating paste is filled between the refrigerant tube 2 and the mounting hole, and a gap between the heat dissipating member 1 and the cover plate 3 is avoided, so that a contact area between the heat dissipating member 1 and the refrigerant tube 2 is increased, and a heat transfer effect is improved.
It should be noted that, in the above two related technical features, the mounting groove 13 is filled with a heat dissipating paste, and the mounting hole is filled with a heat dissipating paste, which may be alternatively or simultaneously set, and obviously, the setting effect is better.
It should be noted that, the greater the depth of the first accommodating groove 14, the more the heat dissipating paste is added, and although the heat conducting effect is improved, the more heat dissipating paste easily flows out slowly from the gaps during use, resulting in a decrease in the contact area between the heat dissipating member 1 and the refrigerant tube, so that the heat dissipating capability of the electrically controlled heat dissipating structure 100 is unstable, and in this embodiment, d1×70%. Ltoreq.h1 is not more than d1×80%.
In addition, although the heat-dissipating paste is coated between the mounting hole and the refrigerant pipe 2, and between the mounting groove 13 and the cover plate 3, the heat-conducting effect is improved, compared with the integral part, the heat-conducting capability is still insufficient, that is, the heat can be transferred from the heat-conducting side 12 of the heat-dissipating part 1 to the mounting side 11 more quickly, so that the heat of the electric control element can be dissipated more quickly, the heat-dissipating paste coated area between the cover plate 3 and the heat-dissipating part 1 has a relatively low heat-conducting rate, and the heat-dissipating effect is poor, so that the cover plate 3 is mounted in an embedded manner on the heat-dissipating part 1 relative to the integral cover, and the heat-dissipating effect of the heat-dissipating part 1 is better.
Further, in order to facilitate heat dissipation from the mounting side 11, referring to fig. 2, the depth of the mounting groove 13 is H3, and the depth of the mounting groove 13 is not less than the thickness of the cover plate 3, so that the two sides of the heat dissipation element 1 are higher than the cover plate 3, on one hand, it is able to avoid the heat dissipation paste from flowing out of the mounting groove 13; on the other hand, the heat of the heat conduction side 12 can be guided to be transferred to the installation side 11, so that the heat is transferred from the heat conduction side 12 to the installation groove 13, and the heat exchange is carried out with the refrigerant pipe 2 positioned at the installation side 11.
Theoretically, the shorter the refrigerant pipe 2 is from the heat conducting side 12, the smaller the thermal resistance of the heat dissipating member 1 is, the more heat the heat dissipating member 1 transfers to the refrigerant pipe 2, the more heat the refrigerant pipe 2 exchanges with the heat dissipating member 1, the more is beneficial to heat dissipation of the heat dissipating member 1, but the heat carried away by the refrigerant pipe 2 in unit time is limited, the too much heat can not be timely carried away by the refrigerant pipe 2, so that the heat is accumulated in the heat dissipating member 1, and thus the heat of an electric control element can not be timely dissipated, therefore, in the embodiment, the distance between the bottom wall of the mounting groove 13 and the heat conducting side 12 is S, wherein, the distance s= (1.7-2) xd1 is set in such a way, so that the heat dissipating member 1 keeps a certain heat dissipation distance, on one hand, the heat is beneficial to be transferred from the heat conducting side 12 to the mounting side 11, the heat is prevented from being accumulated on the heat conducting side 12, and on the other hand, the heat transfer distance of the heat is increased, so that the heat transfer of an electric control element is prevented from being timely, and when the heat transfer distance of the mounting groove 13 is increased, and the heat transfer distance of the bottom wall of the heat dissipating member is 1 x 1.7 x 1, and D1 = 1 mm, and when the heat transfer is further 1.8d1.8m.
The refrigerant pipe 2 may be provided in various forms, such as a hose or a hard pipe, and specifically referring to fig. 3, the refrigerant pipe 2 includes a heat exchange section 21 and a hose section 22, and the heat exchange section 21 is disposed in the installation groove 13; the hose section 22 is arranged outside the mounting groove 13, so that the heat exchange section 21 is a hard tube, so that the heat dissipation part 1 performs heat exchange, and meanwhile, the refrigerant tube 2 outside the mounting groove 13 adopts a hose, so that the refrigerant tube 2 can be broken off as required, so that the heat exchange section 21 is pressed into the heat dissipation part 1, thereby facilitating the installation of the refrigerant tube 2, and it can be understood that the hose section 22 can be a corrugated tube, a pipeline made of elastic materials, and the like.
In order to enhance the heat dissipation effect of the electronic control heat dissipation structure 100, please refer to fig. 4, the mounting holes and the refrigerant pipes 2 are in one-to-one correspondence to form a cooling group, the cooling group is provided with a plurality of cooling groups, and the cooling groups are arranged in the mounting groove 13 at intervals.
It should be noted that, the plurality of refrigerant pipes 2 may be independent or may be mutually communicated, and the plurality of refrigerant pipes 2 independent of each other may form a plurality of inlets and outlets, which have a complex structure and high cost, and the plurality of mutually communicated refrigerant pipes 2 may only have one inlet and outlet, but once one of the refrigerant pipes 2 fails, for example, is blocked, the entire electrically controlled heat dissipation structure 100 may fail, so in this embodiment, the electrically controlled heat dissipation structure 100 includes a refrigerant pipe group including two mutually communicated refrigerant pipes 2, so that the electrically controlled heat dissipation structure 100 may be simplified, and each refrigerant pipe group may be mutually independent and not affect each other, even if one of the refrigerant pipe groups fails, the operation of the rest of the refrigerant pipe groups may not be affected.
In order to facilitate the heat transfer from the electric control element to the heat dissipating member 1, in this embodiment, the heat conducting side 12 is formed with a heat conducting rib 15 facing away from the mounting side 11, and the heat conducting rib 15 is used for thermally connecting with the electric control element, so that the heat dissipating member 1 adopts the heat conducting rib 15, so that the heat dissipating member 1 can be inserted onto the electric element, and the contact between the heat dissipating member 1 and the electric element is facilitated to be enhanced, so that the heat of the electric element is facilitated to be directly conducted to the heat dissipating member 1, and the heat dissipating efficiency of the heat dissipating member 1 is improved. It will be appreciated that the heat conductive ribs 15 may be in various forms for heat conduction with the electronic control element, and may be in direct contact with heat conduction, or may be in indirect contact with heat conduction through a heat conductive medium, for example, a heat conductive medium such as a heat dissipating paste.
It should be noted that, the number of the heat-conducting ribs 15 is not limited, and a plurality of heat-conducting ribs 15 may be provided, and a plurality of heat-conducting ribs 15 may be disposed along the extending direction of the heat-conducting side 12, or may be provided along the extending direction of the heat-conducting side 12.
The heat transfer coefficients of the cover plate 3 and the heat dissipation element 1 may be the same or different, but in order to facilitate heat transfer from the heat conduction side 12 to the installation side 11, in this embodiment, the heat transfer coefficient of the cover plate 3 is greater than that of the heat dissipation element 1, so that the heat transfer coefficient of the cover plate 3 is greater, so that the cover plate 3 can quickly absorb the heat of the heat dissipation element 1, and is conducive to heat transfer from the heat conduction side 12 to the installation side 11 so as to perform heat exchange with the refrigerant pipe 2.
