Description

{COMBINATION WITH FLUID HEAT EXCHANGER BLOCK}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchange block assembly using a fluid, and more particularly, to a heat exchange block assembly in which heat conduction can be performed by transferring heat of heat generation or heat absorption to fluid flowing in a flow passage, Lt; / RTI >

In general, a refrigerator is a device for storing foods for a long period of time by utilizing the principle of latent heat of evaporation (heat of vaporization), in which liquid refrigerant phase-changes into a gaseous state and takes heat from the surroundings.

In such a refrigerator, a cooler for generating cold air is located on the rear side, and chilled air cooled by the cooler is supplied to the freezing room and the freezing room through air blowing.

On the other hand, a dehumidifier that removes water contained in the air is required in an automation facility, a semiconductor manufacturing process, and a chemical production line in contact with water. In this case, the dehumidifier is a system in which a humidifier passing through a cooling coil using a refrigerant is cooled Thereby performing dehumidification.

The cooler and the dehumidifier are provided with a heat exchange block assembly. In the past, as shown in FIG. 1A, a flow path is formed in a zigzag shape by a copper pipe 12, and a diecast casting 14 as shown in Fig.

However, in the block assembly 10, the heat resistance of the copper tube 12 is high and the efficiency is low. In addition, the block joint body 10 is liable to suffer from a side effect and pore phenomenon during the aluminum die casting around the copper tube 12, 12 have a limited distance to form a flow passage (a contact area with the thermoelectric element is small), and the efficiency is further reduced.

It is difficult to weld the heat exchanger louver fin 22 to the inside of the block assembly 10 and then to post-treat the heat exchanger louver fin 22 as shown in FIG. 1B, which is composed of a thin louver fin 22 Since the louver fin 22 is in contact with a fluid such as water to promote oxidation, the thin louver fin 22 itself is oxidized to be thinner and less durable, So that the efficiency as a thermoelectric element and other heat generating elements is lowered and durability is lowered.

In the conventional block assemblies 10 and 20, a plurality of thermoelectric elements (semiconductor modules) are brought into contact with a flat surface of a rectangular box, and the thermoelectric elements generate heat on the opposite surface while absorbing heat from one surface. Is thin as 3-4 mm, heat is transferred between adjacent thermoelectric elements, and the efficiency of the thermoelectric elements is deteriorated.
