本申请公开一种一体式空气源热泵，如图1-5所示，其包括壳体100，壳体100用于形成容纳空间。
容纳空间的顶部设有电器盒200，将电器盒200顶置，充分利用容纳空间，有助于减小整机体积，实现整机的小型化设计。
图6为根据本申请一些实施例的电器盒的结构示意图；图7为根据本申请一些实施例的电器盒的爆炸结构示意图。参照图6和图7所示，电器盒200包括电器盒主体，电器盒主体包括盒体210和盒盖220，盒体210和盒盖220之间围成用于安装元器件的电器盒内部空间。
盒体210包括底侧板211、以及设于底侧板211四周且朝向盒盖220方向延伸的左侧板212、右侧板213、前侧板215及后侧板214。
底侧板211上通过螺钉等连接方式固定连接有支架，支架包括第一支架241和第二支架242，第一支架241和第二支架242为其他部件的安装提供支撑。
第一支架241朝向盒盖220的一侧固定连接有驱动板231，第一支架241朝向底侧板211的一侧通过螺钉等连接方式固定连接有散热器270。
第二支架242朝向盒盖220的一侧固定连接有主控板232，主控板232与调试板234连接。
驱动板231一般集成CPU、压缩机及风机驱动芯片、硅桥等发热元器件，主控板232一般集成电解电容、开关电源芯片等发热元器件，驱动板231的运行电流大，驱动板231的发热量高于主控板232的发热量。
第一支架241位于电器盒200内部空间的中部区域，第二支架242位于电器盒200内部空间靠近右侧板213的右侧区域，底侧板211上设有供散热器270伸出的开口263，散热器270从开口263伸出。
则电器盒200内部空间内，设有驱动板231的中部区域为高热区(记为X1)，设有主控板232的右侧区域为中热区(记为X2)。
底侧板211上还设有电感线圈233，其位于电器盒200内部空间靠近左侧板212的左侧区域内，该区域为低热区(记为X3)。
右侧板213上设有多个第一进风孔251，后侧板214上设有多个第二进风孔252，左侧板212上设有多个出风孔253。
空气从第一进风孔251和第二进风孔252进入电器盒200内部，依次流经中热区X2、高热区X1及低热区X3、而后从出风孔253流出，实现对主控板232、驱动板231及电感线圈233等电器件的通风散热，能耗低、且散热效果好。
与此同时，散热器270对温度较高的驱动板231会进行同步散热，也即驱动板231采用散热器和自然风进行双重散热，可有效快速降低高热区X1的温度。
第一支架241的结构示意图参照图8，第一支架241的周向侧板上及中部区域内设有多个支撑部243，用于与驱动板231抵靠，一方面起到增强第一支架241强度的作用，另一方面对驱动板231起到支撑作用，避免驱动板231发生形变。
第一支架241的周向侧板上还设有多个卡爪244，用于与驱动板231卡接，进一步增强驱动板231的连接可靠性，避免驱动板231翘起。
同样的，第二支架242上也设有多个支撑部和多个卡爪，用于提高主控板232的连接可靠性、减小主控板232的形变。
第一进风孔251、第二进风孔252及出风孔253的孔径优选的小于2mm，在保证通风的情况下，可以避免昆虫等异物进入电器盒200内部而引发意外短路。
盒盖220具有向下翻折的翻板221，翻板221与出风孔253之间具有出风间隙254，在保证通风的情况下，翻板221可以防止雨水进入电器盒200内部而引起短路，提高电器盒200的可靠性。
前侧板215和后侧板214上设有多个走线孔261，用于内部电器的走线。靠近走线孔261的位置还设有绑线架262，用于线路绑线用，使走线更加可靠、整洁有序。
该电器盒200应用于一体式空气源热泵，为了进一步增强电器盒200的散热效果、提高空气源热泵的内部结构紧凑性、减小整机体积，本申请对电器盒200的设置位置、电器 盒200与空气源热泵之间的匹配结构、以及空气源热泵自身的内部结构布局进行了创新性改进。
具体而言，本实施例公开的一体式空气源热泵的结构示意图参照图1至图5，其中图5为一体式空气源热泵的整机结构示意图，图1为其爆炸结构示意图，图2和图3为其内部组件的布局结构示意图，并且图1至图3为了便于表示内部结构，将壳体省略。
参照图5，一体式空气源热泵包括壳体100，壳体100包括底板130、顶板140、左侧壁、右侧壁150、后板，其前部由风机面板160及维修板170构成。
风机面板160设于左侧，其上具有出风口161，用于出风。维修板170设于右侧，需要对壳体100内部的部件进行维修时，将维修板170拆卸下来。
参照图1至图3，底板130上沿竖直方向间隔设有隔板300和支撑板400，隔板300将壳体100的内部空间分隔成左右布置的第一安装空间110和第二安装空间120，支撑板400位于第二安装空间120内、且与隔板300正对。
第一安装空间110内设有第一换热器710，第一换热器710上设有风机支架500，风机支架500上设有风机720。
第二安装空间120内设有压缩机740、制冷系统容器770、水泵750、第二换热器730以及走线管路等。
电器盒200设于第一安装空间110和第二安装空间120的顶部，电器盒200的左端与风机支架500固定连接，电器盒200的右端与支撑板400固定连接，电器盒200的底侧板211与隔板300的上端抵靠。
散热器270和调试板234均位于壳体100的内部空间内。
图4为根据本申请一些实施例的一体式空气源热泵的主视图(省略壳体和第二安装空间内的部件)。图4所示为风机720运行时空气源热泵内部的空气流向，一部分外部空气在风压作用下从电器盒200的第一进风孔251和第二进风孔252流入电器盒200内部，而后从电器盒200的出风孔253流出。
另一部分外部空气在风压作用下从壳体100上的进风口151进入第二安装空间120内、并向上流动，而后经电器盒200的底侧板211上的开口263进入电器盒200内部，最终从出风孔253流出。电器盒200的后侧、右侧及底侧都有气流流入，并从电器盒200的右端流向左端，以对其内部的电器件进行散热，散热效果好、且无死角。
本申请将电器盒200顶置，充分利用壳体100的内部空间，有助于减小整机体积，实现了整机的小型化设计。
在一种可能的实施例中，第一换热器710为L型的翅片换热器，第一换热器710与底板130固定连接，第一换热器710较长的侧部位于第一安装空间110的后侧，第一换热器710较短的侧部位于第一安装空间110的左侧。
风机支架500沿第一换热器710的高度方向延伸设置，风机720位于L型的第一换热器710围成的空间内，以提高换热效率。隔板300靠近第一换热器710的侧边与第一换热器710固定连接。
风机支架500具有风机支架竖向部510和风机支架横向部520，风机支架竖向部510 与第一换热器710固定连接，风机支架横向部520位于风机720的上方。
风机720与风机支架竖向部510固定连接，电器盒200的底侧板211与风机支架横向部520固定连接，以实现电器盒200左端的固定。
在本申请一些实施例中，隔板300为L型结构，隔板300包括隔板主体310和隔板翻边320，隔板主体310与第一换热器710固定连接，隔板翻边320与壳体100的前侧壁连接。
具体为，位于壳体100前侧壁上的风机面板160与隔板翻边320固定连接，维修板170与隔板翻边320可拆卸式固定连接。
L型的隔板300相较于现有技术中通用的C型隔板而言，缩短L型的第一换热器710的长度、并将其与L型的隔板300固定连接，有助于减小其内部占用空间，从而有助于减小整机体积。
第二安装空间120内的部件布局为：压缩机740和制冷系统容器770分别与底板130固定连接，第二换热器730与支撑板400固定连接，水泵750位于压缩机740和制冷系统容器770的上方，水泵750固定设于水泵支架760上，水泵支架760的一端与隔板300固定连接，水泵支架760的另一端与支撑板400固定连接。各部件布局结构紧凑、占用空间小。
第二换热器730可以为水氟板式换热器、壳管式换热器或套管式换热器等。制冷系统容器770可以为储液罐等。
第二安装空间120内还设有支撑横梁600，支撑横梁600的一端与隔板300固定连接，支撑横梁600的另一端与第二换热器730固定连接。
调试板234与支撑横梁600固定连接，实现调试板234的固定安装、避免调试板234晃动。
支撑板400优选为L型结构，支撑板400的下端固定安装于底板130的右侧边和后侧边上，也即支撑板400的下端固定安装于底板130的右后角处，支撑板400的上端同时与电器盒200的右侧板214和后侧板214固定连接，实现电器盒200的右端固定。
至此，电器盒200通过其左端与风机支架横向部520之间的固定连接、右端与支撑板400之间的固定连接、底侧板211与隔板300之间的抵靠、以及调试板234与支撑横梁600之间的固定连接，实现电器盒200的固定安装，使其在空气源热泵的顶部安装结构可靠稳固、且充分利用空气源热泵既有的结构作为安装支撑，占用空间小。
调试板234优选地位于第二安装空间120内，维修时，将前部的维修板170拆卸下来即可对调试板234进行检修，便于操作。
隔板300和支撑板400上均设有多个用于通风的通孔(未标示)，以提高第一安装空间110和第二安装空间120内的空气流动性，有利于散热。
电器盒200的底侧板211与隔板300抵靠时，为了增强二者之间的抵靠牢固性，同时为了增强散热器270的散热效果，本申请对散热器270的结构也进行了结构改进。
具体的，散热器270的结构示意图参照图9，散热器270包括第一散热片组271和第二散热片组272，第一散热片组271与第二散热片组272之间具有空隙273。
隔板300插设于第一散热片组271与第二散热片组272之间的空隙273内、并与底侧板211抵靠，第一散热片组271位于第一安装空间110内，第二散热片组272位于第二安装空间120内。
第一散热片组271和第二散热片组272之间的空隙273对隔板300的上端起到限位的作用，可以防止隔板300的上端倾斜或晃动。
同时，如此设计的散热器270能够充分利用第一安装空间110和第二安装空间120的顶部空间，将散热器270尽可能地做大以提高散热效率。
在本申请一些实施例中，第一散热片组271靠近左侧板212，其靠近风机720的一侧具有斜面部275，该斜面部275用于为风机支架横向部520让位，以便于电器盒200的安装。
同时，第一散热片组271靠近风机720，也便于风机720处的气流对其进行散热，提高散热效率。
在本申请一些实施例中，第二散热片组272靠近右侧板213，第二散热片组272上设有至少一个用于通风的通风风道274，本实施例设有两个通风风道274，通风风道274与第二散热片组272的散热片垂直。
从第二安装空间120的底部向上流动的气流，会经通风通道274从第二散热片组272的内部流过，有助于提高第二散热片组272的散热效率。
图7为根据本申请一些实施例的电器盒的爆炸结构示意图。在一种可能的实施例中，参照图7，电器盒200的后侧板214包括依次连接成阶梯结构的后侧板一部2141、后侧板二部2142及后侧板三部2143，后侧板一部2141与前侧板215之间的距离大于后侧板三部2143与前侧板215之间的距离；第二进风孔252设于后侧板一部2141上。
将后侧板214设计成阶梯状结构，主要是为了使电器盒200能够更好地与第一换热器710等内部组件匹配连接、减小占用空间。
具体的，电器盒200安装到位后，后侧板一部2141位于第一换热器710的右侧，以充分利用第二安装空间120的顶部空间；后侧板二部2142与后侧板三部2143之间的阶梯结构用于为风机支架横向部520让位，以使后侧板214能够紧靠第一换热器710，减小占用空间。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
