Description

Device for tempering an object

The invention relates to a device for controlling the temperature of an object, a temperable cup holder, a battery temperature control device and a method for controlling a tempering process.

In modern vehicles, especially in electric vehicles and hybrid vehicles, more and more electrical components are used whose temperature must be continuously monitored and controlled in order to achieve high efficiency and avoid damage due to overheating or overcooling.

Particularly temperature-sensitive are the accumulators installed in electric vehicles and hybrid vehicles as well as the in-vehicle power electronics. For controlling the temperature of these components are already fluid-based cooling and heating devices and thermoelectric devices use.

In addition, the demand for high-performance and precisely controllable temperature control devices is also increasing in other areas of technology in which heat sources, such as electronic components, must be cooled in order to maintain their functionality.

However, the known tempering devices have the disadvantage that they either have too low a tempering capacity, i. have too low cooling capacity and / or heating power, have too high energy consumption or take up too much space to meet the increasing demands of vehicle manufacturers.

The invention was therefore based on the object to provide a way to at least partially overcome the disadvantages known from the prior art, so that an effective and at the same time energy-saving temperature control of various objects is made possible. The object underlying the invention is achieved by a device for tempering an object, which has a first temperature control device and a second temperature control device. The first tempering is this

The first tempering device and / or the second tempering device are also configured to be heat-transmitting coupled to the object. Preferably, the first tempering fluid differs from the second tempering fluid. The heat-transmitting coupling can be achieved, for example, in that the first tempering device and / or the second tempering device are adapted to be brought into contact with the object, or in that between the object and the first tempering device and / or between the object and the second tempering one or more heat-conducting body are arranged.

The invention makes use of the knowledge that the temperature control can be increased considerably by a combination of two separate fluid-based tempering, wherein a situation-adequate control of the device according to the invention simultaneously allows energy-saving operation of the device. The known from the prior art disadvantages are thus overcome in a surprisingly simple manner by the combination of two fluid-based tempering, which are formed as part of a device. In a preferred embodiment of the device according to the invention, the first tempering device and the second tempering device are coupled to one another in a heat-transmitting manner. The heat-transmitting coupling can be achieved, for example, in that the first tempering device and the second tempering device are in contact with each other, or in that one or more thermally conductive bodies are arranged between the first tempering device and the second tempering device. The first tempering device and the second tempering device can be arranged, for example, one above the other, side by side or offset from one another. Due to the fact that the first tempering device and the second tempering device are coupled to one another in a heat-transmitting manner, a heat exchange can take place between the first tempering fluid and the second tempering fluid. This allows in particular a situation-dependent connection or activation of an additional tempering, if previously, for example, for energy saving reasons, only one of the tempering was operated. The device according to the invention is advantageously further developed in that the first temperature control device or the second temperature control device has one or more ribs or fins and is adapted to exchange heat with a gas or gas mixture surrounding the one or more fins or fins. Ribs and fins increase the surface of a body and thus improve the heat exchange with the environment. As a result, therefore, the effectiveness of the device according to the invention is increased. In particular, the gas mixture is in the form of air, that is to say the gas mixture of the earth's atmosphere. Alternatively, however, other gases or gas mixtures can be used. In a further embodiment of the device according to the invention, the first temperature control device and / or the second temperature control device have one or more fluid channels and are adapted to exchange heat with a liquid flowing in the one or more fluid channels. Due to their high specific heat capacity, liquids are particularly suitable as a tempering fluid. Depending on the operating situation of the device according to the invention, the liquid serves as a coolant or as a heating medium. Preferably, the liquid is formed as water. Alternatively, however, other liquids or mixtures of substances can be used.

In a development of the device according to the invention, the first tempering device and the second tempering device are designed as separate components. This allows a flexible adaptation and / or extension of the device.

Furthermore, in the event of a functional failure of a tempering device, a corresponding

Replacement done without the other temperature control must be replaced.

Furthermore, the formation of the first tempering device and the second tempering device as a separate components to a modular design, whereby the

Manufacturing and assembly costs are reduced.

In a preferred embodiment of the device according to the invention, the first tempering device and the second tempering device are formed as integral components of a one-piece component. In particular, the one-piece component is designed as a cast body. By forming the first tempering device and the second tempering device as integral components of a one-piece component, at least one boundary layer is avoided, whereby the thermal resistance is reduced. The heat transfer is thus further improved, so that the effectiveness of the device according to the invention is further increased. The device according to the invention is further developed advantageously in that the one or more fluid channels are arranged at least in sections within the one or more ribs or lamellae. The wall thickness of the one or more fluid channels, their cross-section and / or their arrangement are preferably to be chosen such that heat exchange takes place between the tempering fluid within the one or more fluid channels and the outer end of the respective rib or lamella. The arrangement of the one or more fluid channels within the one or more ribs or fins, a direct heat exchange between the tempering fluid within the one or more fluid channels and the one or more ribs or fins, through which a further heat exchange with the one or more fins or fins surrounding gas or gas mixture takes place.

In an advantageous embodiment of the device according to the invention, the one or more ribs or lamellae each comprise a bent sheet metal section. The bending of sheets can produce a fin or lamellar structure in a particularly cost-effective manner. Preferably, a multiple bent single sheet forms several or all of the fins or fins. In particular, the sheet or the sheets are formed as stainless steel, aluminum or copper sheets.

Preferably, the one or more bent sheet metal sections each form a sheet metal channel. Within the sheet metal channel, a flow channel is formed. Through the sheet metal channel, the respective rib or lamella has a particularly large surface, which serves for heat exchange with the environment.

In a preferred development of the device according to the invention, in each case a line section of a fluid channel is arranged within a sheet-metal channel. In particular, the one or more fluid channels are formed at least in sections by flexible or rigid conduits, such as tube segments or tube segments. The arrangement of the one or more fluid channels within the one or more sheet metal channels, on the one hand, ensures effective heat exchange between the temperature control fluid flowing in the fluid channels and the temperature control fluid flowing inside the sheet metal channel, and, on the other hand, the power sections within the sheet metal channels are protected from damage protected by mechanical effects. This reduces the risk of a functional failure.

In a further embodiment of the device according to the invention, the first tempering device and / or the second tempering device comprises a cast body, wherein the one or more fluid channels are arranged at least in sections within the cast body. Preferably, the casting is an aluminum casting. Through aluminum die casting processes, fluid channels of different geometries and gradients can be integrated into an aluminum body. The heat exchange between the aluminum body and the tempering fluid is further promoted by the integration of the fluid channels in the aluminum body.

Alternatively, the one or more fluid channels can also be connected by means of soft soldering or brazing in each case with a rib or lamella cohesively. Preferably, the one or more ribs or lamellae each have a receiving portion, which is adapted to receive a fluid channel. Preferably, the one or more fluid channels are at least partially formed as tube segments, preferably made of aluminum, copper or stainless steel.

The differently doped semiconductors are alternately connected to one another on opposite sides via metal bridges, wherein the metal bridges are fastened to the carrier layers. By providing current flow through the semiconductors and their metal bridges, a temperature gradient can be created between the two opposing and spaced support layers. A thermoelectric device, which generates a temperature gradient by means of a current flow, makes use of the Peltier effect and can also be referred to as a Peltier element. Through the use of one or more such thermoelectric devices, the temperature control of the device according to the invention can be further increased, wherein by controlling the flow of current through the one or more thermoelectric devices energy-saving operation is still feasible. In principle, the one or more thermoelectric devices may also be used to generate an electrical current flow be used on the basis of an existing temperature gradient. In this case, the one or more thermoelectric devices take advantage of the Seebeck effect and thus may also be referred to as thermoelectric generators.

By means of the third temperature control device, the fluid temperature of the temperature control fluid of the first temperature control device or the second temperature control device can be controlled. In particular, in situations in which large amounts of heat must be replaced, the use of an additional third temperature control is advantageous. Preferably, the third tempering is switchable, so that an energy-saving operation of the device is ensured in situations in which only small amounts of heat must be replaced.

Preferably, the third tempering device is designed as a tempering device of a vehicle. In particular, the third temperature control device is a motor temperature control device, a charge air temperature control device, a

The device used thus comprises a first tempering device, which is adapted to exchange heat with a first tempering fluid, and a second tempering device, which is adapted to exchange heat with a second tempering fluid.

The method comprises determining the temperature of the object to be tempered and determining the tempering effect on the object to be tempered, caused by a first heat-transferring device coupled to the object in a heat-transmitting manner. The determined tempering effect relates to the expression of the cooling effect and the expression of the heating effect which the first tempering device exerts on the object to be tempered.

The control scheme shown shows the temperature (T ₀ ) of the object to be tempered on the horizontal x-axis and the tempering effect caused by the first temperature control on the vertical y-axis, where AT _R <0 indicates the area in which the first tempering a Cooling effect on the object to be tempered exercises, and AJ _R > 0 indicates the area in which exerts the first tempering a heating effect on the object to be tempered.

The method associated with the illustrated control scheme comprises the step of controlling the second tempering device which is heat-transmittingly coupled to the object and to the first tempering device and a thermoelectric device coupled to the object and to the first tempering device in dependence on the determined temperature of the object.

The control takes place such that the object and the first tempering device are heated by the second tempering device and the thermoelectric device when the determined temperature of the object falls below a first limit temperature 66 and the determined tempering effect cools the object 12 (operating region 72). If the determined temperature of the object is above the first limit temperature 66 and below a second limit temperature 68, additional cooling or heating of the object to be tempered by the second tempering device or the thermoelectric device is not necessary independently of the tempering effect of the first tempering device (operating regions 74a, 74b). If the determined temperature of the object exceeds the second limit temperature 68 and is still below a third limit temperature 70, is an additional cooling or heating of the object to be tempered by the second tempering or the thermoelectric device is not necessary if at the same time the determined tempering of the first tempering heats the object to be tempered (operating range 76). If the determined temperature of the object exceeds the second limit temperature 68 and falls below the third limit temperature and the determined tempering of the first tempering heats the object to be tempered, the object is additionally cooled by the second tempering (operating range 78).

The method further comprises the step of cooling the object by the second tempering means when the detected temperature of the object exceeds the third limit temperature 70 and the determined tempering effect cools the object (operating area 80), and the step of cooling the object by the second tempering means and the thermoelectric device, when the determined temperature of the object exceeds the third limit temperature and the determined tempering effect heats the object (operating region 82).

FIG. 19 shows a further control scheme of an embodiment of the method according to the invention for controlling a tempering process. The method is also carried out with a device for tempering an object, which is designed according to one of claims 1 to 23. The method comprises determining the temperature of the second tempering fluid and determining the travel speed of a vehicle in which the device is installed.

The illustrated control scheme shows the temperature (T _F ) of the second tempering fluid on the horizontal x-axis and the travel speed (v) on the vertical y-axis and a characteristic curve 84.

In accordance with the control scheme, a third tempering device for tempering the second tempering fluid is activated and deactivated as a function of the determined temperature of the second tempering fluid and the determined travel speed. The activation of the third tempering device takes place for all pairs of values in the operating region 88, wherein a deactivation of the third tempering device takes place for all pairs of values in the operating region 86.
