The utility model discloses a strengthening structure of a sealing groove of a heat exchange plate, wherein the heat exchange plate is a rectangular plate, and a round corner hole is arranged at the four corners, and a concave convex interphase channel is arranged on the plate surface. An inner concave sealing groove is arranged on the front surface of the corner hole and the two sides of the heat exchange plate, and the concave section of the sealing groove is composed of two trapezoidal grooves with different sizes and opposite positions. The main section is trapezoidal groove groove large small, trapezoidal groove at the bottom edge of the main subsidiary of the trapezoidal slot opposite the middle is provided with concave, a trapezoidal groove pressing at the bottom edge of the main subsidiary of the trapezoidal slot, the structure forms a rib or ridge, rigid heat plate sheet is greatly improved. Because the structure is strengthened, this kind of heat exchange plate is suitable for large size heat exchanger. In addition, the improved sealing groove and seal form an embedded structure, which can significantly improve the lateral pressure resistance and meet the requirements of the medium and high pressure heat exchanger.

换热板的密封槽强化结构
本技术涉及一种换热器件,具体地讲,本技术涉及一种换热板,特别是一种设有密封槽强化结构的换热板。
技术介绍
板式换热器属于常用型热交换器,其主体由一组均布排列波纹凹槽的换热板叠合而成。由于换热板为薄板件,介质接触换热效率高、热损失小,此种叠合结构紧凑、占地面积小、安装清洗方便。层叠的换热板之间设有密封件,被压紧的柔性密封件在结构中既起到密封作用,又起到换热介质导流作用,自然分隔出冷热两个流体通道。使用时,分别引入的冷热介质在各自通道内流过,与相隔的换热板进行热交换,直至达到用户设定温度。为了便于密封件定位安装,换热板四周及角孔周边均预置了嵌装密封件的凹形密封槽,现有技术的凹形密封槽断面为上大下小的梯形,此种单向内凹结构的密封槽能够容纳密封件。但是,现有技术仅满足小规格且工作压力小于1.6MPa的换热器配套。若超范围应用,造成密封件承载侧向压力加大,易造成密封件滑出凹形密封槽,由此引发密封失效事故。随着城市供暖范围的半径扩大,换热介质的传输压力及流量必须相应加大才能满足沿线用户换热要求。现有技术产品因换热板上单一凹形密封槽结构缺陷,不宜作为大规 ...
