如图1至6以及19至24所示，在本发明的一些实施例中，板式换热器100还包括：背板18，所述背板18设置在换热器100的与所述换热器通道11的通道开口19相对的一侧，所述加强件30具有板状主体31和从板状主体31的中心部分突起的凸起部32，所述板状主体31设置在背板18和与背板18相邻的第一换热板10之间，并且凸起部32朝向通道开口19侧突起。所述板状主体31与背板18和第一换热板10中的至少一个直接接触并连接，例如焊接在一起。例如，所述板状主体31与背板18和第一换热板10直接接触并焊接在一起。凸起部32可以通过第一换热板10的开口13和与第一换热板 10相邻的第二换热板10的开口13伸入第二换热板10和与第二换热板10相邻的第三换热板10之间，或者所述第二换热板10和第三换热板10设有开口，以容纳所述凸起部32。背板18和第一换热板10间的空间与所述换热器通道11可以通过加强件30密封隔离。在本发明的一些实施例中，第一换热板10和第二换热板10间的换热空间与所述换热器通道11密封隔离；第二换热板10和第三换热板10间的换热空间与所述换热器通道11连通。
如图7至18以及25至39所示，在本发明的一些实施例中，所述加强件30设置在两个相邻的换热板10之间(例如设置在上述的第二换热板10和第三换热板10之间)，并与该两个相邻的换热板10中的至少一个直接接触并连接，例如焊接连接。例如，加强件30与该两个相邻的换热板10直接接触并焊接连接在一起。所述加强件30具有加强件通道33，该加强件通道33用于使所述换热器通道11与该两个相邻的换热板10之间的换热空间连通。此外，在背板18和与背板18相邻的第一换热板10之间可以设置板状的加强件，例如圆盘状的加强板。
在本发明的一些实施例中，参见图34至39，所述加强件30还具有中心孔36，沿所述换热器通道11流动的换热介质能够流过该中心孔36。由此，所述加强件30可以设置在两个相邻的换热板10之间，这两个换热板间的换热空间与所述换热器通道11连通。
如图7至18以及25至39所示，在本发明的一些实施例中，所述加强件通道33从所述换热板10的开口13内的位置延伸到所述换热板10的开口13外的位置。
如图11至12以及16至18所示，所述加强件通道33可以是从所述加强件30的外周边向所述加强件30的中心部分延伸的槽。所述槽可以穿过所述加强件30的整个厚度(参见图11至12)或所述槽的深度小于所述加强件30的厚度(参见图16至18)。
如图25至39所示，在本发明的一些实施例中，所述加强件30具有板状主体31，以及多个凸起34，所述多个凸起34在板状主体31的周边部分、从板状主体31向该板状主体31的在与板状主体31 垂直的方向上的一侧伸出，所述多个凸起34中的相邻凸起34之间形成加强件通道33。如图28至30、34至37所示，所述多个凸起34中的至少一个具有开口35，所述开口35朝向从所述加强件30的板状主体31的中心向所述加强件30的板状主体31的周边部分的方向。如图31至33所示，所述多个凸起34具有筒状形成，并且远离板状主体31的端部可以是封闭的。
根据本发明的实施例的用于板式换热器的加强件以及板式换热器可以例如减轻或避免板式换热器的背板和换热板，尤其是靠近背板的两个换热板，在换热器通道周围的区域发生变形或开裂。
此外，根据本发明的实施例的用于板式换热器的加强件以及板式换热器可以降低换热器的成本，并且可以提高换热器的强度，而不会影响换热器的性能。此外，根据本发明的实施例的用于板式换热器的加强件以及板式换热器可以容易地实施。
