Description

一种具有散热功能的UV灯箱 技术领域
本发明涉及凹版印刷技术领域，尤其涉及的是一种可对印刷品上的UV光油进行烘干、固化的具有散热功能的UV灯箱。
背景技术
在凹版印刷中，为使印刷品表面有光泽，多是采用普通光油，印刷品经过上油后晾干可以增加光亮程度。但随着国家对环保节能的要求更加严格，部分印刷品要求使用的涂料或胶粘剂被硬性要求改为UV体系，因而UV固化灯具将会更广泛地应用。由于UV灯管在产生UV光谱的同时，也会产生可见光和红外线，因此，UV灯管在工作时会产生大量热量。
发明内容
本发明的目的在于提供一种可对印刷品上的UV光油进行烘干固化的具有散热功能的UV灯箱，灯箱内设置降温装置，从而实现节能、高效、低温固化的目的，以克服现有技术所存在的不足。
本发明解决其技术问题的技术方案是：一种具有散热功能的UV灯箱，所述灯箱是长方形的，所述灯箱内以间板分隔设置两并排的UV灯室，每个UV灯室设置若干UV灯管；在各的顶部布置半导体制冷装置，所述半导体制冷装置包括半导体制冷芯片、冷端换热器、和热端换热器，所述冷端换热器置于UV灯室内，所述热端换热器置于UV灯室的顶盖上方。
所述UV灯室的底壁设置若干灯槽，所述灯槽底部开口，所述UV灯管安装在灯槽开口上。
所述灯箱的两侧设置支架。
所述UV灯室的两端设置风管腔，在风管腔与UV灯室之间的间板上设置风口，所述风管腔内对应所述风口设置风管弯头，其中一个风管弯头连接鼓风机风道。
本发明的有益效果是：
1、本发明通过在UV灯箱本体的侧壁上设置了多盏UV灯，从而可以在印刷品上UV光油后及时将其固化，十分方便，且成本低廉。
2、本发明通过半导体制冷的方式，对灯箱内环境进行降温处理，从而为UV灯管提供了一个良好的工作环境，延长其平均无故障工作时间。
附图说明
图1是本发明具有散热功能的UV灯箱结构示意图。
图2是本发明具有散热功能的UV灯箱的制冷装置结构示意图。
图3是本发明具有散热功能的UV灯箱的支架结构示意图。
具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“中心”、“横向”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。除非另有说明，“多个”的含义是两个或两个以上。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应作广义理解，例如，可以是固定连接。也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明的具体含义。
参见图1-3，本发明提供一种具有散热功能的UV灯箱，所述灯箱是长方形的，所述灯箱内以间板分隔设置两并排的UV灯室4，每个UV灯室设置若干UV灯管；在各UV灯室的顶部布置有半导体制冷装置，所述半导体制冷装置包括半导体制冷芯片22、冷端换热器24、和热端换热器23。半导体制冷芯片的冷端与冷端换热器接合，半导体制冷芯片的热端与热端换热器接合。因半导体制冷芯片产生的冷量造成冷端换热器处于低温状态，对经过冷端换热器的空气进行降温，使UV灯室的空气温度降低；所述UV灯室的两端设置风管腔1，在风管腔与UV灯室之间的间板2上设置风口21。通过风口向UV灯室内送风，一则加快灯管的降温，二则将在制冷过程中产生的冷凝水汽带走。在所述风管腔内对应所述风口设置风管弯头5，其中一个风管弯头连接鼓风机风道8。
所述UV灯室的底壁设置若干灯槽3，所述灯槽底部开口，所述UV灯管安装在灯槽开口31上。
所述灯箱的两侧设置支架7。
和冷凝水管接头22，所述冷凝水管接头一端连接冷凝水源。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员应当理解：在不脱离 本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同替换所限定，在未经创造性劳动所作的改进等，均应包含在本发明的保护范围之内。
