In the present invention, the cooling block 130 is characterized in that it is modularized with the heat radiation control block 140 and the thermoelectric element 120. This will be referred to as the cooling module 110 in the present specification.

The cooling module 110 may include a cooling block 130 having cold water inlet 133 and a water outlet 132, and a thermoelectric element block 121 provided to be in surface contact with one side of the cooling block 130. ), And the heat dissipation control block 140 in which the coolant circulates, and are provided in surface contact with each other between the thermoelectric element block 121 and the heat dissipation control block 140 and are purified within the cooling block 130. The first thermoelectric element 120 is provided to cool the water and heat the cooling water in the heat dissipation control block 140.

The cooling block 130 has a structure in which cold water from which the cold air is radiated from the radiator 200 is obtained, cooled inside, and discharged. In order to increase the residence time of the cold water in the cooling block 130, the partition wall type formed by repeating the zigzag type may be possible, and the type shown in FIG. 18 will be described later.

Cold water in the present specification means a liquid that serves to send the cold air generated from one surface of the thermoelectric element to the radiator through a pipe formed by receiving the cooling block 130.

The heat dissipation control block 140 is a hot water is introduced, and absorbs the heat generated from one surface of the thermoelectric element and sends it to the heat dissipation device to perform the function of cooling. An inlet 141 for introducing hot water and an outlet 142 for discharging cooling water are provided. The heat dissipation control block also serves to increase the cooling effect by absorbing heat generated from the thermoelectric element to cool the water of the cooling block.

That is, in the heat dissipation control block, one side of the thermoelectric element becomes cold and one side becomes hot in order to cool the thermoelectric element, and this is not heat, but heat dissipation for cooling, enhancing the effect of cooling, and life of the thermoelectric element. However, there is a concept of heat dissipation for low power, but because the concept of heat absorption is included in a complex, the configuration of the heat dissipation control block is made.

Hot water described herein refers to cooling water that serves as a medium for absorbing heat generated from one surface of the thermoelectric element from the heat dissipation control block 140 and sending it to a heat generating device through a conduit.

The thermoelectric element 120 is provided between the cooling block 130 and the heat dissipation control block 140. Since the thermoelectric device 120 is a known technology, a detailed description thereof will be omitted.

The thermoelectric element 120 receives electricity from a power module, which will be described later, to cool the cooling block and to heat the heat radiation control block.

However, the thermoelectric element block 121 is further provided between the thermoelectric element 120 and the cooling block 130.

The thermoelectric element block 121 is made of metal having high thermal conductivity, and uniformly transmits the cold air transmitted from the thermoelectric element to the cooling block 130, and the cooling block in a state in which the function of the thermoelectric element 120 is stopped. The cold air of the 130 is performed to prevent the conduction to the heat radiation control block 140 again.

Referring to FIG. 3, a plurality of thermoelectric elements may be used, and the thermoelectric elements may be provided in surface contact between the case 143 and the thermoelectric element block 121 of the heat dissipation control block 140.

 The present invention is characterized in that to provide a form that can be easily removable by modularizing the cooling block. Therefore, the components described above are fixed in the case for modularization as shown in FIG. 4 to form the cold water module 110.

In addition, a thermo sensor 118 is further attached to the thermoelectric element block 121, and a connector 119 is provided to the outside of the case through a wire. The connector is electrically connected to a control module to be described later to perform a function of transmitting an electrical signal. That is, the control module measures the current temperature of the thermoelectric element block 121 from the temperature sensor 118, and the temperature of the thermoelectric element block 121 may be estimated as the temperature of the cooling block 130. Therefore, the function of controlling the supply of electricity to the thermoelectric element by measuring the temperature of the current cold water or the outside temperature.

Cold water is circulated along the pipe, and is supplied to the cold water module 110 at the first branch point 194. Cold water supplied to the cold water module 110 is introduced into the inlet 133 of the cooling block. However, for the replenishment of hot water, it is also possible to connect some pipes with a heat radiation control block.

The outlet portion 132 of the cooling block is connected to the tube, which is connected to the radiator 200.

A temperature sensor is further attached to the heat dissipation control block 140, and further includes a circulation flow path through which hot water circulates in the heat dissipation control block 140, and heat dissipation devices 186 and 187 provided to the circulation flow path. When the temperature of the temperature sensor is greater than or equal to a predetermined temperature, it is forcibly circulated to the hot water to pass through the heat radiation device (186, 187).

That is, the temperature sensor of the heat dissipation control block 140 is connected to the control module 182. When the temperature is greater than a predetermined value, the hot water inside the heat dissipation control block 140 is supplied to the heat dissipation devices 186 and 187. It is also possible to go through a heat dissipation process, or directly to the outside (191).

In addition, in the case of selecting to use a hot air fan from the outside, the hot air is generated through the above process.

To this end, an automatic valve 195 operated by the control module 182 is connected between the water discharge pipe 141 of the heat dissipation control block 140 and the heat dissipation device.

In addition, the coolant having a lower temperature through the heat dissipation devices 186 and 187 may have a circulation structure in which the cooling water is supplied back to the heat dissipation control block 140 by the circulation pump 185. Arrows in FIG. 1 show the circulation flow of such cooling water.

The power module 183 performs a function of supplying electricity to the control module 182, the operation display 181, the cooling module 110, and the like.

The operation display 181 may be a board having a display and an operation unit at the same time. The operation display 181 may also be provided in the form of a touch screen to provide current information and to be input for control.

5 and 6 show the structure of the cooling water circulation of the heat radiation control block 140 described above.

The heat dissipation device is basically provided in the form of a heat dissipation fin, but if it is determined that the heat dissipation amount is insufficient, the heat dissipation fan may be further installed. Alternatively, a cooling structure using a heat pipe may be applied.

In FIG. 7, the heat dissipation fan is attached to the heat dissipation fin, and the inside of the heat dissipation fin is illustrated to improve cooling efficiency through a heat pipe. The circle shown inside the heat sink fin shows a cross section of the heat pipe.

8 to 10 show another embodiment of the configuration of the cooling module 110 according to the present invention.

The cold water block is the same term as the cooling block, and the control tank can be treated as the same term as the heat radiation control block.

In a new embodiment, two heat radiation control blocks are attached to both sides of the cooling block to further improve the cooling efficiency. The structure using the thermoelectric element block and the thermoelectric element represented by the aluminum block is the same as described above.

However, heat pipes in contact with the thermoelectric elements may be further provided at both sides of the heat dissipation control block. This is to offset the heat energy generated in the control tank. The hot water absorbed heat from the heat dissipation control block is moved to the heat generating device (heat exchanger) through the tube, the hot water discharged heat energy from the heat exchanger is obtained by the pump back into the heat dissipation control block is circulated structure.

10 is a diagram illustrating the circulation of cold water. Cold water cooled in the cooling block (cold pad) is supplied to the radiator by a valve and a water pump. The cold water supplied to the radiator radiates cold air, which is forced out to the outside through the fan to perform a cold wind function.

The main feature of the present invention is to apply a cold and hot module to be mounted on a cold air blower to obtain a cooling effect of the air conditioner, by converting a direct current electricity to use a cold and hot air in a system that is supplied with cold water hot water.

The cold / hot water supply device according to the capacity may be manufactured as a separate device by dividing it into an internal type and an external type.

However, when supplying cold water, there is no problem, but in case of the possibility of freezing which may occur on the opposite side when supplying hot water, 3-way solenoid valve can be used to bypass the hot water.

That is, when freezing problems occur in the radiator, a solenoid valve may be operated to further form a conduit for supplying hot water from a heat radiating control block (or a heat radiating and freezing preheating water chamber) to the radiator.

9 is an embodiment of a structure in which the air supplied through the air filter is discharged to the outside through a radiator having cold air. The reservoir tank is used to replenish the circulating cold water.

The air passing through the air filter is manufactured to pass through an elongated tunnel space. In order to increase the contact time of air with the radiator, the radiator is preferably arranged in the tunnel shape in the longitudinal direction. In addition, the structure is further formed to give a Bernoulli effect to the tunnel-shaped space to further lower the air temperature by the change in air pressure.

A cylindrical fan is provided inside the housing to forcibly discharge the air introduced through the inlet through the air filter to the outlet. The outlet is designed to be formed in a direction perpendicular to the inlet, and a radiator is located at the center to distinguish the tunnel. However, the diaphragm should be placed so that the air on the outlet side does not go to the opposite side to guide the air toward the outlet.

11 illustrates an embodiment of an internal structure of the cooling block 130.

In this case, the cooling block 130 includes an inlet pipe 137 connected to the inlet unit 133 and an outlet tube 138 connected to the outlet unit 132 therein, and the inlet tube 137. The end of the cooling block 130 is provided on the upper side and is provided to face upwards, the end of the outlet pipe 138 is provided on the lower side of the cooling block 130 is provided to face downward.

This is to allow the cold water in the block to circulate using the density difference according to the temperature. It is preferable that the tube is provided in a U-shape as shown in FIG. 11 so that the tube faces upward, and it is preferable that the tube is provided in an I-shape so that the tube is provided downward.

That is, in the case of the cooling block, the temperature is higher than the side on which the receiving side exits. Therefore, the fresh water introduced into the inside is located at the upper side, and after some cooling, it moves to the lower side. Since the end of the outlet pipe is located at the lower side, the water in which cooling is completed to some extent can be discharged to the outside. That is, when the end of the outlet pipe is located on the upper side, or when the end of the inlet pipe is located on the lower side, the problem that the purified water introduced into the block may be discharged even before cooling, the present invention may be It is to provide the above structure to solve.

As mentioned above, although preferred embodiments of the present invention have been described, the present invention is not limited to the embodiments described above, but is defined by the claims, and various modifications and adaptations can be made in the technical field to which the present invention belongs. Is self-explanatory.
