Description

The invention relates to a heat exchanger unit according to the main claim.In conventional heat exchangers, two components to be connected are usually aligned with one another, pressed against one another and subsequently connected in a materially bonded manner. Accurate positioning is necessary for this purpose.The object of the invention is to provide an improved heat exchanger unit.Against this background, the approach presented here presents an improved heat exchanger unit. The features listed in the dependent claims allow advantageous refinements and improvements of the device specified in the independent claim.The approach presented makes it possible to create a possibility by means of which, for example, a very tight and stable connection between the cover plate and the receiving unit can be created and / or a soldering behavior of individual components can be improved. Advantageously, the connection of the components can be simplified and at the same time realized more stably. The approach is advantageously simple to implement, cost-effective and universal, so that it can be used for a wide variety of areas.A heat exchanger unit is presented, which comprises a heat exchanger element comprising a plurality of plates arranged one above the other and a cover plate, which has a first connection in a cover section and a second connection in a coupling section, wherein the heat exchanger element has a tube element arranged on the cover plate for conducting a fluid, which connects the first connection and the second connection to one another, through said tube element. Furthermore, the heat exchanger unit has a receiving unit for receiving the coupling section of the cover plate, wherein the receiving unit has a receiving plate with at least one holding element arranged on the receiving plate. The fluid is preferably a coolant and may be a mixture of glycol and water. The heat exchanger unit and thus the heat exchanger element is supplied with the fluid to a further fluid on two flow paths that are fluidically separated from one another, so that the two fluids transfer heat to one another. The heat exchanger element can have plates that deviate geometrically from the plates, in order to represent deflections of the fluids within the heat exchanger element, for example.The heat exchanger unit can be advantageously used for different areas, such as for engines, a passenger compartment, batteries or electric machines in general. The cover plate can cover, for example, a body of the heat exchanger element through which the fluid can be guided. The cover plate can be designed, for example, as a one-piece component. The tubular element can be made of the same material as the cover plate, for example. For example, the tube element can be arranged fixedly on the cover plate and additionally or alternatively be connected in a materially bonded manner. The pipe element can be formed as a U-pipe in order to conduct the fluid from the first connection to the second connection. Advantageously, by using the receiving unit with the holding element, a secure connection can be established between the heat exchanger element and the receiving unit. Furthermore, manufacturing costs can be advantageously saved.According to one embodiment, the holding element can be oriented at least partially transversely to the receiving plate. Advantageously, by aligning the two elements with respect to one another, a slipping of the cover plate on the receiving plate can be prevented.Furthermore, the holding element can be arranged on a lateral edge of the receiving plate. Advantageously, the holding element can thereby prevent a lateral displacement of the cover plate.According to one embodiment, the receiving unit can be formed as a C-shaped flange. Advantageously, the shape of the flange can improve stability of the heat exchanger unit.Furthermore, the receiving plate can have a through-opening which, in the mounted state of the cover plate on the receiving plate, can be aligned with the second connection within a tolerance range. For example, the cover plate and the receiving plate can overlap at least partially. Advantageously, the through-opening can be realized as a connection opening for a channel which can connect to the pipe element.The holding element can also have a connecting region in which the holding element can be connected to the coupling section. The connecting region can be realized, for example, as a location at which the holding element and the cover plate can be pressed together. For example, the connecting region can be designed as a mechanically deformed region of the holding element.According to one embodiment, the receiving unit can have a further holding element, which can be arranged on a side of the receiving plate opposite the holding element. The two holding elements can advantageously be arranged on mutually opposite sides of the receiving unit. This makes it possible to achieve a more secure secure holding of the cover plate.The heat exchanger element and the receiving unit can be connected or connectable to one another in a materially bonded manner, in particular soldered or solderable and additionally or alternatively welded or weldable. The connection of the two elements can be advantageously improved.According to one embodiment, the heat exchanger element can be pushed into the receiving unit and additionally or alternatively pushed in and additionally or alternatively connected or connectable in a force-fit manner. Manufacturing can be advantageously improved since the positioning of the heat exchanger unit on the receiving unit can be simplified. Manufacturing costs can also be reduced in an advantageous manner as a result.Furthermore, the receiving unit can be prefabricated and / or formed in one piece. Manufacturing costs can advantageously be reduced.Further details and advantages of the present invention are evident from the following description of exemplary embodiments in conjunction with the drawing. These show, in each case schematically: FIG. 1 shows a schematic illustration of an exemplary embodiment of a heat exchanger unit; FIG. 2 shows a schematic illustration of an exemplary embodiment of a heat exchanger unit; and FIG. 3 shows a schematic illustration of an exemplary embodiment of a heat exchanger unit.In the following, identical and / or functionally identical elements can be provided with the same reference numerals. The absolute values and measurements given below are merely exemplary values and do not represent a restriction of the invention to such dimensions.FIG. 1 shows a schematic illustration of an exemplary embodiment of a heat exchanger unit 100. The heat exchanger unit 100 is usable in connection with electric machines, motors, batteries and / or in connection with a passenger compartment. The heat exchanger unit 100 is designed, for example, to transfer thermal energy from one substance to another substance and is thus used for temperature control, such as, for example, in air conditioners or gas heaters.The heat exchanger unit 100 has a heat exchanger element 105 comprising a plurality of plates 111 arranged one above the other and a cover plate 110 which has a first connection 120 in a cover section 115 and a second connection 130 in a coupling section 125. The plates 111 are arranged connected to one another one above the other to form the heat exchanger element 105. Furthermore, the heat exchanger element 105 has a tube element 135 arranged on the cover plate 110 for conducting a fluid through which the first connection 120 and the second connection 130 are connected to one another. For example, the cover plate 110 and the tube element 135 are embodied in one piece or are connected to one another in a materially integral manner, for example welded or soldered. Furthermore, the heat exchanger unit 100 has a receiving unit 140 for receiving the coupling section 125 of the cover plate 110, wherein the receiving unit 140 has a receiving plate 145 with at least one holding element 150 arranged on the receiving plate 145. According to this exemplary embodiment, the receiving unit 140 can be designated as a connection element which can be coupled to external components or components. The receiving plate 140 further has a through-opening which, in the mounted state of the cover plate 110 on the receiving plate 140, is aligned with the second connection 130 within a tolerance range. More specifically, the through-opening and the second port 130 overlap, so that the channel formed by the tube element 135 is continued through the through-opening and the fluid can preferably be discharged from the heat exchanger element 135. The through-opening is described in FIG. 3.The holding element 150 is oriented at least partially transversely with respect to the receiving plate 145. This means that the holding element 150 extends away from the receiving plate 145 according to this exemplary embodiment. It is also arranged on a lateral edge of the receiving plate 145. For example, the holding element 150 additionally has a projection in order to hold the coupling section 125 of the cover plate 110. The cover plate 110 is held by the holding member 150 in two different directions, so that the heat exchanger member 105 is prevented from being displaced. More specifically, the receiving unit 140 is formed as a C-shaped flange. Furthermore, the holding element 150 according to this exemplary embodiment has a connecting region 155, in which the holding element 150 is connected to the coupling section 125. The projection described above is embodied or can be implemented as part of the connecting region 155. More precisely, the connecting region 155 has at least one point 157 and, according to this exemplary embodiment, two points 157 on the holding element 150, which are connected and / or mechanically deformed in a pressed, materially bonded and / or force-fit manner in order to couple the heat exchanger element 105 and the receiving unit 140 to one another. The heat exchanger element 105 and the receiving unit 140 are therefore connected or connectable to one another in a materially integral manner, in particular soldered or solderable and / or welded or weldable.Furthermore, the receiving unit 140 optionally has a further holding element 160 which is arranged on a side of the receiving plate 145 opposite the holding element 150. Both holding elements 150, 160 are realized in the same way. As a result, the heat exchanger element 105 can be pushed and / or pushed into the receiving unit 140 and / or connected or connectable in a force-fitting manner, for example pressable. The receiving unit 140 is prefabricated only optionally.The heat exchanger unit 100 and heat exchanger element 105 have two flow paths for two fluids which are separated from one another in terms of fluid technology and which flow through the heat exchanger unit 100 and thus transfer heat to one another. It is conceivable that the one fluid is a coolant and the further fluid is, for example, an oil to be cooled.FIG. 2 shows a schematic illustration of an exemplary embodiment of a heat exchanger unit 100 as has been described, for example, in FIG. 1. Here too, the heat exchanger element 105 is inserted into the receiving unit 140. The holding elements 150, 160 are also realized in a C-shaped manner according to this exemplary embodiment. Likewise, the holding elements 150, 160 together with the receiving plate 145 form a C-shape.FIG. 3 shows a schematic illustration of an exemplary embodiment of a receiving unit 140 of a heat exchanger unit, which corresponds, for example, to the receiving unit described in at least one of FIGS. 1 to 2. According to this exemplary embodiment, the receiving unit 140 is only shown detached from the heat exchanger element after they have been connected to one another in order to be able to represent a soldered joint 300. The soldered joint 300 surrounds the through opening 305 arranged in the receiving plate 145 and which can be coupled to the tube element of the heat exchanger element not shown in FIG. 3.List of reference characters100 Heat exchanger unit 105 Heat exchanger element 110 Cover plate 111 Plate 115 Cover section 120 First connection 125 Coupling section 130 Second connection 135 Pipe element 140 Receiving unit 145 Receiving plate 150 Holding element 155 Connecting region 157 Location 160 Further holding element 300 Soldering location 305 Through opening
