Description

[0001] The present invention relates to a compact type heat exchanger,

The present invention relates to a compact heat exchanger, and more particularly, to a compact heat exchanger of a new structure which is light in weight but portable, and can heat a sufficient amount of water in a shortest time by a simple structure.

BACKGROUND ART [0002] Generally, a heat exchanger circulates a fluid such that heat exchange is performed by a heating medium for the purpose of cooling or heating the fluid, and a housing having a cylindrical shape is provided so that the fluid is stored or refined. Tubes or a coil tube is wound around the outer circumferential surface of the housing.

In such a heat exchanger, conventionally, the housing, the end cap, or the like is made of a casting molded by a flask. This is not only complicated to manufacture according to the manufacturing process of the casting mold, There is a problem.

In addition, when a cast product is used in a product requiring airtightness such as a heat exchanger due to the generation of bubbles in the manufacturing process, moisture permeability due to bubbles may be generated to lower the heat exchange efficiency. In addition, There is a problem in that the heat exchanger itself is difficult to be miniaturized, and there is a limit in diversifying the use of the heat exchanger itself.

In addition, when the conventional heat exchanger is compactly formed, the capacity of the water to be heated is small, and thus the heat exchanger is limited in its ability to exhibit sufficient heating capacity due to its compact structure.

The inlet 31 and the inlet 31 are formed at the upper and lower sides of the housing 31, respectively, A pump 36 for pumping water flowing through the inlet 32 is coupled to the upper end of the housing 31 and a heater 37 to be described later is attached to the lower end of the housing 31, A control box 38 in the form of a rectangular box is provided so as to be operable. The detailed configuration and operation of the present invention will be described with reference to FIGS. 2 to 4. FIG.

2, an inlet port 32 is formed in the upper side wall of the housing 31, an induction hole 40 corresponding to the pump 36 side to bypass the water, and an induction hole 40 And the diffusion plate 41 is formed at an end of the diffusion plate 41. The pump 36 is provided with a fastening ring 43 fastened to a threaded portion 42 formed around the upper end of the housing 31 so as to be detachably mounted on the housing 31, A heater 37 inserted into the housing 31 through a lower end of the housing 31 is disposed in the housing 31. The heater 37 includes at least one heater rod 44 for heating water, And a sensor rod 45 positioned at one side of the sensor rod 45 to detect the temperature of the water.

3 and 4, the housing 31 is formed with an internal inflow pipe 39 communicating with the inflow port 32 and extending to the inside thereof, and the internal inflow pipe 39, Is formed in a tube shape having a relatively small diameter as compared with the cross sectional area of the housing 31. One side of the inner inflow pipe 39 in the longitudinal direction is communicated with an upper portion of the inner inflow pipe 39 to guide water flowing into the inflow opening 32, (40).

A dish-shaped diffusion plate 41 is formed at the upper end of the induction hole 40 so as to form a relatively large area relative to the induction hole 40 at the upper side of the inner inlet pipe 39, The plate 41 divides the inside of the housing 31 into an upper space 46 having a certain area and a lower space 47 relatively larger than the upper space 46.
