Description

一种内燃机工程机械用高低温散热器
技术领域
本实用新型涉及内燃机冷却领域，特别是指一种内燃机工程机械用新型高低温散热器。
背景技术
目前，多数内燃机工程机械都采用液冷方式并配有油冷器，散热器冷却内燃机通常采用空冷方式。工程机械的作业靠液压机构实现，液压机构工作时会产生热量，靠液压油油冷器冷却。工程机械的液力变矩器液力耦合器机械变速器都使用传动油，工作时会产生热量，靠传动油油冷器冷却。其中，传动油工作温度较高，最高温度大约在115℃，采用空冷方式或采用液冷方式，液压油工作温度较低，最高温度一般不超过95℃，和内燃机的出水温度非常接近，通常采用空冷方式。在工作过程中，内燃机缸体热量被冷却液吸收，利用水泵动力将冷却液输送到外部的散热器，再通过风扇将热量交换到自然界的空气中；工作中液压油或传动油温度升高后，依靠油泵动力将液压油或传动油输送到外部的油冷器，如果油冷器采用空冷方式，则通过风扇将热量交换到自然界的空气中，如果油冷器采用液冷方式，则将热量交换到冷却液中。
现有技术中，内燃机出水温度最高通常不超过97℃，进水温度通常为91℃，液压油油冷器的进油温度大约为95℃，出油温度大约89℃，由于水油温差太小，无法用冷却液来冷却液压油，因此，液压油油冷器通常用空冷方式，油管路长且复杂，油阻大，空间布置难度大，设计难度大，故障率高。
实用新型内容
本实用新型的目的在于提供一种内燃机工程机械用新型高低温散热器，以便克服上述不足，提供一种效率更高安装简单的散热器，方便使用。
为了实现上述目的，本实用新型的技术方案如下。
一种内燃机工程机械用新型高低温散热器，在散热器上设置有依次连通的进水管、进水水室、散热器芯体、出水水室、隔水板和出水管，所述进水管和所述进水水室连通，所述进水水室和所述散热器芯体连通；所述散热器芯体根据冷却液降温幅度和冷却空气进入的先后顺序分为散热器低温芯体和散热器高温芯体两个部分；所述出水水室中间设置有隔水板，所述隔水板将出水水室分隔成低温出水水室和高温出水水室两部分，出水管根据冷却液流出的芯体和水室不同分为低温出水管和高温出水管。
进一步地，所述散热器低温芯体是所述散热器芯体进风侧芯体，所述散热器高温芯体是所述散热器芯体出风侧芯体，冷却空气先冷却所述散热器低温芯体，然后再冷却所述散热器高温芯体。
进一步地，所述散热器低温芯体和所述低温出水水室连接，所述散热器高温芯体和所述高温出水水室连接。
进一步地，所述低温出水水室与所述低温出水管连接，所述高温出水水室与所述高温出水管连接。
该装置中，从所述低温出水管流出的低温冷却液完成后续的换热后和从所述高温出水管流出的高温冷却液汇合，依靠水泵动力进入内燃机缸体对内燃机冷却。
该实用新型的有益效果在于：该实用新型中，散热器芯体分为散热器低温芯体和散热器高温芯体两部分；出水水室分为低温出水水室和高温出水水室；出水管分为低温出水管和高温出水管。从内燃机流出的高温冷却液进入散热器芯体，一部分进入散热器低温芯体，一部分进入散热器高温芯体，冷却空气先冷却散热器低温芯体再冷却散热器高温芯体，流经散热器低温芯体的冷却液降温幅度大，流出时成为低温冷却液，流经散热器高温芯体的冷却液降温幅度小，流出时成为高温冷却液，低温冷却液用来冷却高温液压油和高温传动油，然后和高温冷却液一起汇合进入内燃机。这种散热器设置，结构简单，安装方便，效率高，节约了使用成本，提高了使用效率。
附图说明
图1为本实用新型装置结构示意图。
图2为本实用新型装置侧视图。
具体实施方式
下面结合附图对本实用新型的具体实施方式进行描述，以便更好的理解本实用新型。
如图1、图2所示的内燃机工程机械用高低温散热器，包括：依次连通的进水管1、进水水室2、散热器芯体3、出水水室4、隔水板5和出水管6，所述进水管1和所述进水水室2连通，所述进水水室2和所述散热器芯体3连通，所述散热器芯体3根据冷却液降温幅度和冷却空气进入的先后顺序分为散热器低温芯体31和散热器高温芯体32两个部分；出水水室4中间设置有隔水板5，将出水水室4分隔成低温出水水室41和高温出水水室42两部分，出水管6根据冷却液流出的水室和芯体的不同分为低温出水管61和高温出水管62；散热器低温芯体31是散热器芯体3进风侧芯体，散热器高温芯体32是散热器芯体3出风侧芯体，冷却空气先冷却散热器低温芯体31，然后再冷却散热器高温芯体32。散热器低温芯体31和低温出水水室41连接，散热器高温芯体32和高温出水水室42连接。低温出水水室41与低温出水管61连接，高温出水水室42与高温出水管62连接。从低温出水管61流出的低温冷却液完成后续的换热后和从高温出水管62流出的高温冷却液汇合，依靠水泵动力进入内燃机缸体对内燃机冷却。
在本实用新型的具体实施例中，进水管1和内燃机出水管连接，当内燃机工作时，高温冷却液从内燃机出水管输出，进入散热器的进水管1，如图1中B处所示，然后进入进水水室2，一部分冷却液进入散热器低温芯体31，一部分冷却液进入散热器高温芯体32，从外界进入的冷却空气，首先进入散热器低温芯体31给里面的冷却液降温，冷却空气温度升高冷却液温度下降，如图1中A处所示，热交换结束后，散热器低温芯体31里的冷却液进入低温出水水室41流经低温出水管61，输出到外界，冷却空气冷却散热器低温芯体31后再进入散热器高温芯体32给里面的冷却液降温，冷却空气温度继续升高冷却液温度下降，热交换结束后，散热器高温芯体32里的冷却液进入高温出水水室42流经高温出水管62，输出到外界。在冷却空气进入散热器低温芯体31的时候，冷却空气温度低，和散热器低温芯体31里的冷却液有大的温差，冷却空气冷却能力大，因此散热器低温芯体31里面的冷却液降温大，从散热器低温芯体31输出的冷却液成为低温冷却液，冷却空气给散热器低温芯体31冷却后升温大，再进入散热器高温芯体32，此时，升温后的冷却空气和散热器高温芯体32里的冷却液有小的温差，冷却空气冷却能力小，因此散热器高温芯体32里面的冷却液降温小，从散热器高温芯体32输出的冷却液成为高温冷却液。从低温出水管61输出的冷却液，用来给液压油和传动油降温，然后和高温冷却液混合进入内燃机给内燃机降温。根据测试，低温冷却液的降温幅度一般为高温冷却液降温幅度的2.5～3倍。在内燃机工程机械中，如果把两个油冷器去掉，散热器承担内燃机、液压油和传动油的冷却，散热器芯体正面面积比普通内燃机散热器增加80％左右，工程机械95℃的发动机出水温度，从低温散热器芯体流出的低温冷却液的温度大约下降15～18℃，温度大约在77～80℃之间，匹配合适的油冷器，能够满足液压油的冷却要求。
以上所述是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本实用新型的保护范围。
