The present invention relates to a combustion chamber structure of a heat compression type air conditioner, and in particular, a metal mesh, a heat diffusion pipe, and an insulation layer are formed inside to allow sufficient heat exchange with internal components before the high temperature heat generated in the combustion chamber is discharged to the outside of the combustion chamber. It is an object of the present invention to provide a combustion chamber structure of a heat compression type air conditioner which prevents loss of heat and high temperature heat to be discharged out of the combustion chamber.

In the conventional case, in the combustion chamber structure of the heat compression air conditioner of FIG. 4, a plurality of heating tubes 20 and a connecting tube are connected to a regenerator at the upper end of the cylinder 30, so that the high temperature heat generated from the heat source is The heating tube 20 and the connection tube are heated and discharged out of the combustion chamber 10 to increase the annual loss, and the upper part of the cylinder is locally heated so that the high temperature heat is transferred through the cylinder 30 to increase the heat loss. Since the pipes are formed to cool the outer wall of the separate cylinder 30, the number of parts increases.

In addition, the high temperature heat generated in the combustion chamber is 650 ° C-700 ° C in the case of gas, and passes through the inside of the heating tube through which the internal gas is circulated. When the temperature of the high temperature heat is discharged out of the combustion chamber, the temperature is 180 ℃ -200 ℃ is the most ideal temperature, but conventionally about 320 ℃ high heat is discharged to the outside of the combustion chamber has a problem that the heat exchange rate is reduced.

Accordingly, the present invention has been devised in view of the above-described conventional problems, and the technical configuration and effect for achieving the object of the present invention will be described in detail with reference to the accompanying drawings.

In the heat compression type air conditioner, a plurality of coupling grooves 5a are drilled on the cylinder 3 inside the combustion chamber 1 to prevent conduction heat, and to be combined with the heating tube 2 on the upper side thereof. Mounting a circular heat insulating plate (5) and a circular heat diffusion plate (6) formed by drilling a plurality of heat diffusion groove (6b) and a heating pipe coupling groove (6a) in the center of the heating tube (2) above the heat insulating plate (5) Combined to be located in, but provided with a fine mesh metal mesh (7) coupled to the outside of the body of each heating tube (2) combined with the heat insulating plate (5) and the heat diffusion plate (6), not described. 8, 8 'is a piston, 9 is a combustor, 10 is a drive motor, 11 is a crankshaft.

Referring to the working effect of the present invention configured as described above with reference to one embodiment in detail as follows.

As shown in FIG. 1, a heat compression heat pump generally fills a cylinder 3 having three different temperature spaces a, b, and c with high pressure with a gas such as helium or hydrogen. 3) It is equipped with a high temperature piston 8 and a low temperature piston 8 'which move back and forth with a certain phase difference, and cause them to change the temperature of the gas by moving the gas filled in each space. To obtain a cooling and heating output from isothermal expansion and isothermal compression, and its operation is as follows.

When fuel is supplied to the combustor 9 and air outside the combustion chamber 1 is mixed, combustion occurs in the combustion chamber 1 to generate high temperature heat, and when the power is applied to the driving motor 10, the motor rotates. Power is transmitted to the crankshaft 11 to convert the rotational movement to the up and down reciprocating motion, and the high temperature piston 8 and the low temperature piston 8 'have a regular phase reciprocating motion with a constant phase difference.

Therefore, the high temperature heat heated in the combustion chamber 1 heats the heating tube 2 to heat the gas filled at high pressure.

At this time, the gas in each of the different temperature space is moved to the top or vice versa. (I.e., the high temperature chamber (a) gas moves to the middle temperature chamber (b) and the middle temperature chamber gas moves to the low temperature chamber (c) or vice versa)

Subsequently, as the heating and cooling output is obtained by the continuous reciprocating motion of the high temperature piston 8 and the low temperature piston 8 ', it acts as a heat pump, and the high temperature heat generated in the combustion chamber is outside the combustion chamber 1. The higher the temperature of the waste heat discharged, the lower the heating / cooling output. In order to prevent this, in order to increase the heat exchange of the high temperature heat and the high-pressure filled gas in the combustion chamber (1), the metal mesh (7) is combined to the outside of the heating tube (2) to produce a heat storage effect. A heat insulating layer (ceramic, mica) is formed to prevent this conduction, and a heat insulating plate 5 is attached to the top of the heat insulating layer 4 so that high temperature heat can evenly heat the heating tube 2, and the heating tube 2 The interruption portion is equipped with a circular thermal diffusion plate 6 to prevent high temperature heat from being locally heated.

In addition, the heat of high temperature is circulated to the bottom by the plurality of heat diffusion grooves 6a formed in the heat diffusion plate 6 to increase the heat exchange.

As seen above, the high temperature at which the heat generated from the combustion chamber 1 is discharged out of the combustion chamber 1 is due to poor heat exchange with the internal parts of the combustion chamber 1. Since the heat is reduced to a high temperature heat discharged out of the combustion chamber after heat exchange and prevent the high temperature heat is transferred through the upper cylinder (3) is to improve the efficiency.
