Definitions
- the invention relates to an arrangement for the promotion of fluids, for. B. of liquid and / or gaseous media.
- the cooling liquid flows through not only the heat absorber, but also a liquid pump, which causes the forced circulation and causes an adequate pressure build-up and volume flow through the heat receiver and an associated heat exchanger, so that the heat transfer coefficients associated with these heat transfer coefficients and the temperature gradients necessary for heat transfer become small.
- a fan In the heat exchanger usually a fan is arranged, which causes a forced convection of the cooling air and good transfer coefficients on the air side of the heat exchanger.
- the rotor of the arrangement is designed as a permanent magnetic rotor, which allows a compact design, in particular, when the second permanent magnet is formed integrally with the permanent magnetic rotor.
- FIG. 1 shows a longitudinal section through a preferred embodiment of an inventive arrangement
- FIG. 2 shows an enlarged detail of FIG. 1.
- FIG. 1 shows a longitudinal section through an arrangement 120 according to the invention.
- the latter has on the outside an approximately cylindrical fan housing 122 with two flanges 124, 126, at the corners of which is in each case a fastening bore 128 and which are connected to one another by a tubular part 130.
- the flange 126 is connected by webs or spokes 132 with the lid 138 of a pump housing 136.
- On the cover 138 is an inlet tube 140.
- the lid 138 is liquid-tightly connected to the housing 136 in the manner shown.
- the cylindrical peripheral portion 144 is in Fig. 1 right over into a portion 148 which is perpendicular to the longitudinal axis 150 of the assembly 120.
- This longitudinal axis 150 corresponds to the Rotary axis of an electronically commutated internal rotor motor 152, the stator 154 and the bell-shaped rotor 156 are designated. Winding elements of the stator 154 are designated by 158.
- An advantage of the arrangement 120 is that the stator 154 and the rotor 156 may be long relative to the assembly 120, that is, one may use a high power motor 152.
- the rotor 156 is mounted on a shaft 160 which, for its support, has a left bearing 162 and a right bearing 164, as shown in FIG. These are - because of the life - rolling bearings.
- the inner ring of the left rolling bearing 162 is fixed on the shaft 160.
- the inner ring of the right roller bearing 164 is slidably disposed relative to the shaft and clamped by a compression spring 166 relative to the rotor 156, which thus spring pushes the inner ring of the rolling bearing 164 to the right while pressing the inner ring of the rolling bearing 162 to the left to a smooth running to ensure the arrangement 120.
- the outer ring of the rolling bearing 164 is mounted in a tubular extension 168 of the housing 136, which may also be referred to as a bearing tube 168.
- a short shaft 170 for a pump wheel 172 of a centrifugal pump 174 is mounted in the housing 136 as shown.
- the impeller 172 is for this purpose provided with a sintered bearing 176 that slides on the fixed shaft 170 and forms a sliding bearing with this.
- the shaft 170 is secured to a portion 180 of the housing 136, which portion is approximately perpendicular to the longitudinal axis 150. It merges into a cylindrical portion 182 which extends between a hollow cylindrical, permanent magnetic portion 184 of the rotor 156 and a hollow cylindrical extension 186 of the impeller 172. As shown, the hollow cylindrical portion 184 overlaps the bearing 164, resulting in a very compact construction.
- the cylindrical portion 182 of the housing 136 in turn merges into an annular portion 188 which is perpendicular to the longitudinal axis 150, and this in turn merges into a portion 190 which extends around the outer periphery of the impeller 176 and merges into the section 148.
- the sections 180, 182 and 188 of the housing 136 form a so-called split pot. Since the housing 136 is made of plastic, it acts for magnetic flux lines such as air, but is naturally fluid-tight, so that liquid flowing through the inlet 140 into the fluid pump 174 is transported by this pump, and again through an outlet 192 outwardly flows, as indicated by arrows 194, 196, and do not exit the pump 174 to the outside can.
- the hollow cylindrical extension 186 of the impeller 174 is radially magnetized, z.
- a magnetic coupling is formed between the extension 184 of the permanent-magnetic rotor 156 and the extension 186 of the impeller 172, and when the rotor 156 rotates during operation, this rotation by the magnetic coupling 184 , 186 transmitted to the impeller 172, so that this also rotates.
- the impeller 172 also has a ring-shaped portion 200 which is formed as a permanent magnet and which cooperates with the stray magnetic field at the lower end of the rotor 156 and also forms part of the magnetic coupling, that is, a portion of the torque from the rotor 156th transmits to the impeller 172.
- the upper bearing 162 of the rotor 156 which is shown in FIG. 2, is arranged in a collar 202 of a housing part 204, which, as shown, may be cup-shaped.
- This collar passes over a kind of bearing plate 206 in a cylindrical portion 208 which encloses most of the stator 154 and ends at a flange 210 which is connected to a flange 212 of the housing part 144, for. B. as shown by a latching connection by means of a plurality of latching hooks 213, of which only one is shown.
- These are preferably mounted on the radially inner side of the flange 212 and allow a very simple assembly.
- the collar 202 is located in a recess of the housing part 204, and out of this recess, the shaft end 214 of the shaft 160 protrudes.
- the hub 216 of a cup-shaped fan 218 is pressed on which fan blades 220 are arranged in the usual manner.
- this fan wheel 218 transports air in the axial direction through the fan housing 122, and this air is preferably used to cool a liquid cooler for the fluid from the fluid pump 174.
- the fan can be used as needed, e.g. also be designed as diagonal or radial fan.
