Receiver dryer with bottom inlet

A receiver dryer, comprising:

• a canister having a longitudinally-extending cylindrical sidewall, a lower end wall integral with a lower end of said canister and an opening at an upper end of said canister, said lower end wall having an inlet port;
• an end cap secured to the upper end of the canister, said end cap having an outlet port;
• a conduit including an inlet tube passage and a pick-up tube passage, said inlet tube passage fluidly connected to the inlet port in the lower end wall and extending upwardly toward the upper end of the canister, and said pick-up tube passage fluidly connected to the outlet port in the end cap and extending downwardly toward the lower end of the canister;
• a desiccant tube assembly supported within said canister, said desiccant tube assembly including a longitudinally extending tube, said desiccant tube closely receiving the conduit;
• a first baffle having a peripheral dimension closely matching an interior dimension of said sidewall, said first baffle having a first opening which is bounded by said tube of the desiccant tube assembly;
• a second baffle having a peripheral dimension closely matching the interior dimension of said sidewall and a first opening fluidly-sealed to said tube of said desiccant tube assembly;
• loose desiccant material disposed in said canister and surrounding said desiccant tube assembly between said first and second baffles.

A receiver dryer, comprising:

• a canister having a longitudinally-extending cylindrical sidewall, an end wall secured to a first, closed end of said canister and an end cap secured to a second, open end of the canister, said end wall having a first port and said end cap having a second port;
• a first tube fluidly connected to the first port in the end wall and extending toward the open end of the canister to a first port;
• a second tube fluidly connected to the second port in the end cap and extending toward the closed end of the canister to a second port;
• a desiccant tube assembly supported within said canister, said desiccant tube assembly including a longitudinally extending desiccant tube, said first and second tubes being received in said desiccant tube;
• a first baffle having a peripheral dimension closely matching an interior dimension of said sidewall and an inner dimension fluidly sealed to the desiccant tube assembly;
• a second baffle having a peripheral dimension closely matching the interior dimension of said sidewall and an inner dimension secured to the desiccant tube assembly;
• desiccant material disposed in said canister and surrounding said desiccant tube assembly between said first and second baffles.

A method for assembling a receiver/dryer, comprising the steps of:

• providing a canister having a longitudinally-extending cylindrical sidewall, a closure member secured to one end of said sidewall and an opening at another end of said sidewall;
• providing a first baffle in fluid-tight surrounding relation to a desiccant tube assembly, said desiccant tube assembly having a pair of desiccant tubes;
• inserting the desiccant tube assembly and the first baffle into the canister through the open end, with a first surface of said baffle facing said closed end of said canister and said periphery of said first baffle being closely received in said canister;
• locating loose desiccant in said canister, said loose desiccant being supported by a second surface of said first baffle;
• inserting a second baffle with an opening over the desiccant tube assembly, with the desiccant tube assembly being received in said opening in the second baffle, and a first surface of the second baffle supporting the loose desiccant material and said periphery of said second baffle being closely received in said canister;
• inserting a first tube into one of the tubes of the desiccant tube assembly, said first tube being fluidly connected to an opening in the closed end of the canister, said desiccant tube assembly and said first tube having a fluid-tight seal;
• and
• attaching an end cap to the open end of said canister, said end cap having at least one fluid flow opening extending through the end cap, and a second tube fluidly connected to the opening in the end cap, said second tube being received within the other of the tubes of said desiccant tube assembly with a fluid-tight seal.

A method for assembling a receiver/dryer, comprising the steps of:

• providing a canister having a longitudinally-extending cylindrical sidewall, a closure member secured to one end of said sidewall and an opening at another end of said sidewall;
• providing a first baffle in fluid-tight surrounding relation to a desiccant tube assembly, said desiccant tube assembly having a desiccant tube;
• inserting the desiccant tube assembly and the first baffle into the canister through the open end, with a first surface of said baffle facing said closed end of said canister and said periphery of said first baffle being closely received in said canister;
• locating loose desiccant in said canister, said loose desiccant being supported by a second surface of said first baffle;
• inserting a second baffle with an opening over the desiccant tube assembly, with the desiccant tube assembly being received in said opening in the second baffle, and a first surface of the second baffle supporting the loose desiccant material and said periphery of said second baffle being closely received in said canister;
• inserting a conduit into the tube of the desiccant tube assembly, said conduit being fluidly connected to an opening in the closed end of the canister, said desiccant tube assembly and said conduit having a fluid-tight seal;
• and
• attaching an end cap to the open end of said canister, said end cap having at least one fluid flow opening extending through the end cap, said conduit being fluidly connected to the opening in the end cap, said conduit being received within said tube of said desiccant tube assembly with a fluid-tight seal.

A method for assembling a receiver dryer wherein the receiver dryer includes a canister having a longitudinally-extending cylindrical sidewall, a closure member secured to one end of said sidewall and an opening at another end of said sidewall;

• and a first baffle in fluid-tight surrounding relation to a desiccant tube assembly, comprising the steps of:
• inserting the desiccant tube assembly and the first baffle into the canister through the open end, with a first surface of said baffle facing said closed end of said canister and said periphery of said first baffle being closely received in said canister;
• locating loose desiccant in said canister, said loose desiccant being supported by a second surface of said first baffle;
• inserting a second baffle with at least one opening over the desiccant tube assembly, with the desiccant tube assembly being received in said at least one opening in the second baffle, and a first surface of the second baffle supporting the loose desiccant material and said periphery of said second baffle being closely received in said canister;
• inserting a pair of tubes through at least one conduit in the desiccant tube assembly, one of said tubes being fluidly connected to an opening in the closed end of the canister, said desiccant tube assembly and said tubes having a fluid-tight seal;
