图 2示出了用于取暖装置的换热器 1。 如图 2所示， 该换热器 包括一个换热器壳 8， 在本实施例中该换热器壳被制成方筒状， 但 是本发明并不局限于此， 其也可呈圆筒状或任何其他适当的形状。 换热器壳 8 限定了一个换热腔 4， 腔内设有一个换热芯体。 该换热 芯体包括一排管 3， 其是由两块带凹凸槽的薄基板对合， 或由两张 平薄基板中间夹有窄条等物垫成夹层而形成夹层导槽形的排管。 本 领域的技术人员应该知道， 也可采用其他方式制作本发明的排管。 该排管 3的横截面可具有如局部放大的图 3A— 3C所示的各种形式。  Fig. 2 shows a heat exchanger 1 for a heating device. As shown in FIG. 2, the heat exchanger includes a heat exchanger shell 8. In this embodiment, the heat exchanger shell is made into a square tube shape, but the present invention is not limited to this, and it may be cylindrical. Shape or any other suitable shape. The heat exchanger shell 8 defines a heat exchange cavity 4, and a heat exchange core is provided in the cavity. The heat exchange core includes a row of tubes 3, which are formed by two thin substrates with concave and convex grooves, or sandwiched by narrow strips and the like sandwiched between two flat thin substrates to form a sandwich guide groove. tube. Those skilled in the art should know that other methods can be used to make the pipe of the present invention. The cross section of the row of pipes 3 may have various forms as shown in Figs. 3A to 3C, which are partially enlarged.
图 4为图 2中沿 C一 C线剖取的换热腔的一个实施例的剖面图， 示出了换热芯体的布置结构。 其中， 排管 3 可呈波浪形， 或者是任 何有利于提高换热效率的适当排列形式。 排管 3 的两端分别与热介 质注入管 1 和热介质排出管 2流体连通。 结合图 1和图 4， 在换热 器壳 8 的两端分别设有一个换热腔入口 6和一个换热腔出口 7。 在 靠近入口 6和出口 7的位置处分别设有热介质排出管口 10和热介质 注入管口 9, 它们分别与相应的热介质排出管 2 和热介质注入管 1 流体连通。  FIG. 4 is a cross-sectional view of an embodiment of the heat exchange cavity taken along the line C-C in FIG. 2, showing the arrangement structure of the heat exchange core. Among them, the row of tubes 3 may be wavy, or any appropriate arrangement that is beneficial to improve the heat exchange efficiency. Both ends of the discharge pipe 3 are in fluid communication with the heat medium injection pipe 1 and the heat medium discharge pipe 2, respectively. With reference to Figs. 1 and 4, a heat exchange cavity inlet 6 and a heat exchange cavity outlet 7 are provided at two ends of the heat exchanger shell 8, respectively. Near the inlet 6 and the outlet 7, heat medium discharge nozzle 10 and heat medium injection nozzle 9, respectively, are provided, which are in fluid communication with the corresponding heat medium discharge pipe 2 and heat medium injection pipe 1, respectively.
下面结合图 2— 5说明本发明换热器 1的工作情况。 由于热介质 注入管 1和热介质排出管 2与排管 3 的两端联通， 并置于换热器壳 8内， 从而形成换热腔 4。 热介质注入管口 9置于换热腔出口 7处， 热介质排出管口 10置于换热腔入口 6处， 以增加热对流效应。 本发 明设置为热介质注入管 1 处于下部， 热介质排出管 2处于上部的状 态。 对其换热腔内通入高温液体或气体， 同时， 经热介质注入管口 9 注入换热介质。 此时， 换热介质将经过排管 3 换热， 再从热介质 排出管口 10排出。 在此过程中， 因排管 3的成型基板很薄， 导槽管 径极小， 换热介质在其中与换热腔 4 中的高温液、 气体进行充分的 热交换， 使换热介质温度升高， 而高温气、 液体温度降低， 从而实 现换热的目的。 本发明采用的排管结构中的夹层导槽形式， 具有毛 细管的功能， 容易形成热定向对流效应， 有利于介质流动， 大大减 小了排管内的阻力， 提高换热效率。 同时， 排管形式又可以令热交 换均匀性能也大幅度提高。 The operation of the heat exchanger 1 of the present invention will be described below with reference to FIGS. 2-5. The heat medium injection pipe 1 and the heat medium discharge pipe 2 are in communication with both ends of the pipe 3 and are placed in the heat exchanger shell 8 to form a heat exchange cavity 4. The heat medium injection nozzle 9 is placed at the heat exchange cavity outlet 7 and the heat medium discharge nozzle 10 is placed at the heat exchange cavity inlet 6 to increase the heat convection effect. The present invention is provided in a state where the heat medium injection pipe 1 is in the lower part and the heat medium discharge pipe 2 is in the upper part. A high-temperature liquid or gas is passed into the heat exchange chamber, and at the same time, the heat exchange medium is injected through the heat medium injection nozzle 9. At this time, the heat exchange medium will exchange heat through the tube 3, and then from the heat medium The discharge nozzle 10 is discharged. In this process, because the forming substrate of the tube 3 is very thin and the diameter of the channel tube is extremely small, the heat exchange medium performs sufficient heat exchange with the high-temperature liquid and gas in the heat exchange chamber 4 to increase the temperature of the heat exchange medium. High, and the temperature of high-temperature gas and liquid decreases, thus achieving the purpose of heat exchange. The sandwich guide groove form in the tube structure adopted by the invention has the function of a capillary tube, which is easy to form a thermal directional convection effect, which is conducive to the flow of the medium, greatly reducing the resistance in the tube and improving the heat exchange efficiency. At the same time, the form of piping can greatly improve the uniform performance of heat exchange.
图 6和图 7示出了本发明第二实施例的换热腔 4'的结构。 该换 热腔 4'的结构与第一实施例的结构相类似， 因此， 相同或相似的部 件采用相同或相似的标号。  6 and 7 show the structure of a heat exchange chamber 4 'according to a second embodiment of the present invention. The structure of the heat exchange cavity 4 'is similar to that of the first embodiment. Therefore, the same or similar parts are given the same or similar reference numerals.
