另外，若干所述毛细管腔20于所述板体内部沿所述第二方向并排均匀分布，这样，一方面可提高热交换速率以加快冷冻和解冻速度，另一方面还可改善均温效果。
任意两个所述毛细管腔20彼此隔离不相通。
每个所述毛细管腔20的内壁设置有微齿结构21，所述微齿结构21包括连续分布的微齿211及位于相邻两个微齿211之间的齿槽212。所述微齿结构21设置为，所述齿槽212沿所述第一方向延伸，以使所述热交换介质可沿所述齿槽212流动形成毛细现象，从而进一步加快热交换速率及改善均温效果。
在本发明一实施方式中，在平行于所述第二方向的纵向截面上，所述微齿结构21设置为波浪形。所述齿槽212包括远离所述毛细管腔20中心的波谷2120，所述波谷2120设置为圆弧形，这样可避免所述热交换介质于所述波谷2120处因阻力过大造成的流动率降低，使所述热交换介质的流动更顺畅以提升热交换效率。同样，所述微齿211包括靠近所述毛细管腔20中心的波峰2110，所述波峰2110也设置为圆弧形，以提升热交换效率。同时，所述波谷2120和所述波峰2110设置为圆弧形，还可减小所述板体100的成型难度，保证产品质量。
另外，在平行于所述第二方向的纵向截面上，所述毛细管腔20设置为矩形，包括竖直方向相对设置的顶壁和底壁、及沿所述第二方向相对设置的两个侧壁，所述顶壁位于靠近所述正表面11的一侧，所述底壁位于靠近所述后表面12的一侧。所述微齿结构21至少设置于所述底壁处。在附图实施例中，所述微齿结构21设置于所述底壁和所述顶壁处。当然，除设置于所述顶壁和所述底壁外，所述微齿结构21还可设置于两个所述侧壁处。
另外，相邻两个所述微齿211之间的夹角大致呈20°。
在附图所示实施例中，所述毛细管腔20设置为一封闭空间，所述封闭空间内填充有所述热交换介质，也即，所述毛细管腔20不与所述板体100的外部空间相连通，所述热交换介质只能在所述毛细管腔20内循环流动。具体的，所述板体100还包括设置于其沿所述第一方向相对侧的封边部13，任意所述毛细管腔20沿所述第一方向延伸至两个所述封边部13内侧并被所述封边部13所封闭。这样，还可增强所述板体100的均温效果。
在其他实施例中，所述毛细管腔20还可设置为一开放式空间。具体的，所述毛细管腔20包括第一开口和第二开口，所述热交换介质可通过所述第一开口、所述第二开口进出所述毛细管腔20。也即，所述毛细管腔20可通过所述第一开口、所述第二开口与容置有所述热交换介质的其他装置相连通。所述第一开口和所述第二开口沿所述毛细管腔20的延伸方向相对设置，以增大所述热交换介质的流动率。
另外，参看图4和图5，本发明一实施方式还提供了一种所述导热板的板体100的生产方法，所述方法包括步骤：
通过挤出工艺成型出基础板体；所述基础板体包括成型于其内部的若干毛细管腔，每个所述毛细管腔包括分别设置于所述基础板体第一端、第二端的第一开口、第二开口；
压接所述第一端以密封所述第一开口；
将所述第二开口通过充注管与真空泵相连通，并对所述毛细管腔抽真空；
向所述毛细管腔内灌入热交换介质；
沿所述毛细管腔的延伸方向按定长对所述基础板材压接封边并切断，得到至少一个所述板体。
具体的，以附图4所示的实施例为例，所述方法包括步骤：
于模具内通过挤出工艺成型出基础板体1；所述基础板体1设置为铝合金材质，包括成型于其内部的若干毛细管腔，每个所述毛细管腔包括分别设置于所述基础板体1的第一端101、第二端102的第一开口、第二开口；
压接所述第一端101以密封所述第一开口；例如，通过滚压所述第一端101可于所述第一端101处形成封边部13，在该过程中，位于所述第一端101处的若干所述第一开口均封闭，从而使所述毛细管腔仅通过所述第二开口连通所述基础板体1的外部空间；
将所述第二开口通过充注管200与真空泵相连通，并对所述毛细管腔抽真空；
向所述毛细管腔内灌入热交换介质；所述热交换介质可设置酒精或R134a(全称为1，1，1，2-四氟乙烷)；
沿所述毛细管腔的延伸方向按定长对所述基础板材1压接封边并切断，具体可采用滚压的压接方式，得到至少一个所述板体100。
其中，定义所述毛细管腔的延伸方向为第一方向，所述第一端101与所述第二端102沿所述第一方向相对设置。所述毛细管腔可通过所述第一开口、所述第二开口连通所述基础板体1的外部空间。
若干所述毛细管腔沿垂直于所述第一方向的第二方向并排均匀分布，每个所述毛细管腔的内壁设置有微齿结构。
在本发明一实施方式中，所述步骤“将所述第二开口通过充注管200与真空泵相连通，并对所述毛细管腔抽真空”包括：
将充注管200焊接至所述第二端102以使所述第二开口与所述充注管200连通；
连通所述充注管200与真空泵，并对所述毛细管腔抽真空。
所述步骤“向所述毛细管腔内灌入热交换介质”包括：
通过所述充注管200向所述毛细管腔内灌入热交换介质。
这样，在抽真空和灌入热交换介质的过程中，所述充注管200均可作为通道以实现与所述毛细管腔的连通，减小了工艺复杂度。
另外，在本发明一实施方式中，所述步骤“沿所述毛细管腔的延伸方向按定长对所述基础板材1压接封边并切断，得到至少一个所述板体100”包括：
沿所述毛细管腔的延伸方向按定长对所述基础板材1压接封边并切断；
对切断面进行焊接，得到至少一个所述板体100。
这样，即可实现多个所述板体100的同步生产，不仅保证了产品质量，而且大大提高了生产效率。
与现有技术相比，本发明具有以下有益技术效果：通过一体成型的板体，并于板体内设置毛细管腔，大大改善了导热板的均温效果和热交换效率；通过设置微齿结构，使得热交换介质可沿微齿结构形成毛细现象，进一步增强热交换效率；通过一体成型生产制作的板体，加工工艺简单且可保证生产成本降低。
上文所列出的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
