Definitions
- the invention relates to a regenerator and one Process for producing a regenerator according to the Genre of main claims.
- U.S. Patent No. 5,469,709 a Regenerator for a Vuilleumier heat pump described in through special measures on the inside wall of the housing Leakage currents between the inside wall of the housing and the edge area the regenerator matrix are to be prevented.
- the Limit memory matrix by ring elements that by in grooves are introduced into the housing inner wall.
- the inner wall of the regenerator is wavy embody.
- regenerator according to the invention and the inventive Processes for producing a regenerator have the Advantage that free space, for example, due to production are between the housing of the regenerator and the Regenerator matrix or in the marginal areas of the Regenerator matrix safe, simple and can be avoided cost-effectively. So that in this Leakage and bypass flows of the Working medium flowing through the regenerator is prevented.
- fillers in the edge area of the storage matrix be introduced offer themselves in an advantageous manner Plastics, such as silicones or resins.
- Plastics such as silicones or resins.
- metals can also be used as Fillers are used.
- regenerator results when the filler or Filler layer is mechanically resilient and therefore at the same time forms the housing wall of the regenerator.
- the regenerator is produced according to the invention in that on the edge region of the memory matrix Filler is applied in liquid or viscous form, which penetrates into the edge area of the memory matrix and there cures.
- Figure 1 shows a sectional view of the Overall structure of one after a regenerative gas cycle process working Vuilleumier heat pump
- Figure 2 a Partial representation of a regenerator, as from the state of the Technology is known
- Figure 3 is a partial view of the inventive regenerator after a first Embodiment
- Figure 4 is a partial view of the inventive regenerator after a second Embodiment.
- the overall structure is one by one Vuilleumier heat pump working with a regenerative gas cycle shown.
- the heat pump instructs cylindrical and pressure-tight housing 10, which in present embodiment is constructed in three parts.
- a housing part is located above a central housing part 12 14, hereinafter referred to as the heater head, arranged, that with the help of fasteners 16 on the middle Housing part 12 is flanged while at the bottom of middle housing part 12 with the help of Fasteners 18 and an intermediate plate 20 lower housing part 22 is attached.
- the heater head 14 is surrounded by a housing cover 24, in which as essential element a heat generator in the form of a Gas burner 26 is arranged.
- the gas burner 26 has one Mixing chamber 28, in the one hand a feed pipe 30 for the fuel gas and on the other hand a combustion air line 32 flows into.
- the gas burner 26 also has two curved baffles 34, 36 for the fuel gas-air mixture and a burner surface 38 acting as a reaction surface on, through which the mixing chamber 28 is limited and at the with the help of an ignition device 40 the fuel gas-air mixture is ignited.
- the one that acts as the reaction surface Burner surface 38 consists of a stainless steel mesh, which at Operation of the gas burner 26 glows, so that much of the generated heat is emitted by radiation.
- the cylinder space formed are two arranged one behind the other Pistons 48, 50 are provided, between the pistons 48 and the partition of the heater head 14 is an upper work space 52, an intermediate one between the piston 48 and the piston 50 Working space 54 and below the piston 50 a lower one Working space 56 is formed.
- the piston 48 is attached to a piston rod 58, while the piston 50 on a coaxial to the piston rod 58 guided piston rod 60 is attached.
- Both piston rods 58, 60 lead into the lower pressure-tight housing part 22, in which is arranged a gear, not shown, on known way the movement of the two piston rods 58, 60 and thus the linear up and down movement of the pistons 48, 50 controls.
- Regenerators 62, 64 arranged during the Gas cycle have the task of the internal energy of the working gas located in the working spaces 52, 54, 56 temporarily.
- the regenerators 62, 64 stand with the Working spaces 52, 54, 56 in connection, so that through the Movement of the pistons 48, 50 the working gas between the Workrooms 52, 54, 56 is periodically shifted. That in Working space 52 located working or process gas via the thermal drive source of the gas burner 26 heated. When the piston moves upwards 48 becomes the hot process gas located in the working space 52 via the regenerator 62, which is part of the process heat stores, moved to the middle workspace 54.
- regenerator 64 performs the corresponding function on one lower temperature level: part of the thermal energy of the process gas in the working space 54 is by the regenerator 64 stored when the process gas through the piston 50 upward movement from the middle Workspace 54 moved into the lower workspace 56 becomes.
- a first heat exchanger 66 is arranged, a part of the via an appropriate heat transfer medium transported between workrooms 52 and 54 Process heat can absorb.
- One below the cold Regenerator 64 arranged second heat exchanger 68 is of the working gas on the way from the working room 54 over the cold regenerator 64 to the cold working space 56 Process heat applied.
- This cold heat exchanger 68 supplies the working gas located in the working space 56 the cold side in the expansion phases with that for the Heat pump process characteristic secondary heat.
- the regenerators 62, 64 essentially consist of the prior art (see Fig. 2) is known from a Housing 70, in which a porous storage matrix 72 is arranged is.
- the porous storage matrix is generally covered by metallic knitted fabrics or fleeces formed; as well are wire mesh, granulate or ball fill as well similar structures and materials are conceivable.
- the Memory matrix 72 as complete and even as possible from Working gas can be flowed through. As shown in Figure 2 is formed between the housing 70 and the Memory matrix 72 or in the edge areas of the Memory matrix free spaces or inhomogeneities that Cause leakage currents of the working gas.
- Figure 4 is a second embodiment of the invention shown, in which the filler 74 'at the same time Housing wall of the regenerator forms, causing a additional regenerator housing can be dispensed with.
