    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0023] Some embodiments of the tube arrangement according to the invention are explained in more detail below with reference to the figures. These schematically show the following:

    [0024] FIG. 1 shows a tube arrangement with a throttle valve molded into the base body;

    [0025] FIG. 2 shows a tube arrangement with several separately formed functional elements; and

    [0026] FIG. 3 shows a further tube arrangement with several separately formed functional elements.

    DETAILED DESCRIPTION

    [0027] FIG. 1 shows a tube arrangement 1 for the transport of temperature control medium or tempering medium, comprising a base body 2 made of polymeric material and produced by means of blow molding. In the base body 2, at least one functional element 3 is arranged, which is in operative connection with the tempering medium. The functional element 3 is arranged in a channel 4, the functional element 3 being formed in one piece from the base body 2. The functional element 3 forms a throttle valve and is formed by a cross-sectional narrowing of the channel 4.

    [0028] FIG. 2 shows a tube arrangement 1 according to FIG. 1, the base body 2 comprising a plurality of functional elements 3 which are formed separately from the base body 2 and are arranged in the interior of the base body 2. The base body 2 has a plurality of channels 4, a channel wall 5 being located between each of the channels 4.

    [0029] The tube arrangement 1 comprises several functional elements 3, including a check valve 3′, a temperature sensor, a pressure sensor, a flow sensor and a connector in the form of a connection block 3″ for connecting the tube arrangement 1 to adjacent units or tubes/lines/pipelines. Furthermore, the tube arrangement 1 has a throttle valve 3′″ which is molded directly into a channel 4 and which is molded from the base body 2 as a single material and in one piece.

    [0030] FIG. 3 shows an alternative embodiment of the tube arrangement 1 shown in FIG. 2. Several functional elements 3 in the form of a check valve 3′ and several connectors 3″″ are introduced into the tube arrangement 1.

    [0031] The tube arrangements 1 shown in FIGS. 1 to 3 form part of an air conditioning circuit of an air conditioning system, the air conditioning system being designed as a mobile air conditioning system of a motor vehicle. According to a further embodiment, the tube arrangements 1 form part of a temperature control circuit of the drive unit of an electric vehicle, the tube arrangements 1 supplying tempering medium to the cells of the batteries and the electrical control components and plug connections.

    [0032] In a further embodiment, the tube arrangement 1 is part of a temperature control device, which is set up to control the temperature of components of the drive unit of electric vehicles. In addition to the battery, this includes the power electronics and the electric motors. Furthermore, the temperature control device is set up to cool the charging electronics and the associated plug connections and lines, which is particularly advantageous in connection with fast charging processes.

    [0033] Furthermore, the temperature control device can be set up to control the temperature of components of the remaining vehicle electronics, in particular to cool them. Such components are, for example, sensors and computers for autonomous driving and on-board computers.

    [0034] In the method for producing a tube arrangement 1 according to FIG. 1, a preform made of polymeric material is provided, the preform being arranged in a blow mold and the tube arrangement 1 being shaped by means of a blow molding process. The blow mold is designed in such a way that the functional element 3 is molded into the tube arrangement 1.

    [0035] In the method for producing a tube arrangement 1 according to FIG. 2, a parison made of polymeric material of at least one functional element 3 to be arranged inside the tube arrangement 1 is first provided, the at least one functional element 3 being arranged in the interior of the preform, wherein the parison with the at least one functional element 3 arranged therein is arranged in a blow mold and the tube arrangement 1 is formed by means of a blow molding process. The throttle valve 3′″ is formed from the base body 2 during the blow molding. Accordingly, the blow mold is designed in such a way that the functional element 3 in the form of the throttle valve 3′″ is molded into the tube arrangement 1 with this method as well.
