Description

Heat Exchanger {HEAT EXCHANGER}

The present invention relates to a heat exchanger, and more specifically, it is possible to heat the driving heat of the electrical component to the outside through self-heat exchange without directly introducing air into the electrical component to cool the driving heat of the electrical component, And a heat exchanger capable of maintaining a heat exchange function without adding any additional equipment for the heat exchanger.

(Hereinafter, referred to as "electrical equipment") for automatically and precisely machining and manufacturing parts such as automobiles, etc., which are likely to malfunction due to driving heat, and a separate heat exchanger for lowering the heating temperature.

Conventional heat exchangers have mainly utilized a cooling fan system in which external air is forced into an electric component to exchange internal air of an electric / electronic sub assembly (ESA) with external air. However, the heat exchanger of this type causes the dust scattering around the electrical component to flow into the electrical component, which causes the operation error of the electrical component to be rather caused.

In order to solve this problem, the conventional heat exchanger is further provided with a filter for filtering the air forced into the electrical component. However, since the filter has its own lifetime, it has to be replaced every cycle, and since the filter has to be purchased and replaced every time for the replacement, it is not practical in terms of economy and management efficiency.

In order to solve this problem, a heat exchanger using cooling water has been proposed. However, in the conventional heat exchanger using cooling water, a cooling water pipe has to be separately installed in the electric component, and a separate device for cooling the heated cooling water has to be added, which complicates the structure of the heat exchanger and raises the manufacturing cost. Moreover, conventional heat exchangers of this type have also been limited in that they can not be applied to ready-made electrical products.

The heat exchanger 100 according to the present embodiment includes a heat transfer body 110, a first heat transfer body 120 connected to one side of the heat transfer body 110 for heat conduction, And a second heat sink 130 connected to the second heat sink.

As is well known, the heat conductor 110 has a material and structure excellent in thermal conductivity, and functions to transfer heat generated at one end to the other end. As the heat conductor 110, a mechanism such as a heat pipe is utilized, and a more detailed description thereof will be repeated below.

The first and second heat sinks 120 and 130 are formed of a material and a shape and structure for effective heat exchange with the periphery. Generally, the first and second heat sinks 120 and 130 have a double-layer structure in which a plurality of plates are arranged in parallel to each other. The heat radiator is made of an aluminum material having an excellent thermal conductivity. In addition, if the thermal conductivity is high, various materials can be applied within the scope of the following right.

The first and second heat sinks 120 and 130 are connected to one side of the heat sink 110 for heat exchange with the heat sink 110. The first heat sink 120 is connected to one side of the heat sink 110, 130 are connected to the other side of the heat transfer member 110 so that the first and second heat sinks 120 and 130 are point-symmetrical with respect to the heat transfer member 110. Accordingly, the heat of the first heat discharging body 120 is transmitted to the second heat discharging body 130 through the heat conducting body 110. As a result, the heat applied to one surface of the heat conductive member 110 is transmitted to the other surface of the heat conductive member 110, and the heat of the space defined by the heat conductive member 110 is efficiently transmitted to another space.

1, the heat exchanger 100 according to the present embodiment includes a first diaphragm 141 that covers one side of the heat transfer member 110 and a second heat sink 130 that covers the first heat transfer member 110, And a second diaphragm (142) covering the other surface of the heat transfer element (110).

The first and second diaphragms 141 and 142 divide the heat transfer member 110 into two spaces forming a boundary. As shown in FIG. 3, air in the first compartment space S1 directly passes through the heat transfer member 110 So as to block the flow into the second compartment space S2. This is because when the external air flows into the electric component E through a gap between the heat conductive member 110 and the housings 140 and 160 or the like, the external dust is also directly introduced into the electric component E and contaminates the interior of the electric component E, And the two diaphragms 141 and 142 are covered on one surface and the other surface of the heat transfer member 110 to block the inflow of external dust. The heat exchanger 100 of the present embodiment is separated into the outer housing 160 and the inner housing 140 so that the outer cool air can be efficiently circulated in the inner housing 140. This will be described in more detail below.

The heat exchanger 100 of the present embodiment further includes a housing 140 or 160 housing the heat transfer body 110 and having the air inlet ports 147 and 161 and the outlet ports 148 and 162 formed therein. The heat exchanger 100 of the present embodiment is arranged such that the heat transfer member 110 is arranged to partition the hollow of the housings 140 and 160 and the inflow ports 147 and 161 and the outflow ports 148 and 162 are connected to the housings 140 and 160 ), Respectively.

In this embodiment, the inner housing 140 is installed in the outer housing 160 in order to partition the hollow of the housings 140 and 160. As a result, the first compartment space S1 is formed by the inner housing 140 and the second compartment space S2 is formed in the outer housing 160 where the inner housing 140 is removed. The boundary between the first and second partition spaces S1 and S2 is the first and second partition plates 141 and 142 covering the heat transfer member 110 as shown in FIG. Are combined with each other to form the inner housing 140.

The inner housing 140 includes a first member 143 connected to the lower end of the first diaphragm 141 corresponding to the front face and forming a bottom face thereof and a second member 143 connected to the upper end of the second diaphragm 142, The first and second members 144 and 142 and the first and second members 143 and 144 are connected to the first and second diaphragms 141 and 142, , 146). The first member 143 is in contact with the outer housing 160 and has an inlet 147 and an outlet 148 communicating with the electrical component E respectively.

Since the first diaphragm 141 connected to the first member 143 and the second diaphragm 142 connected to the second member 144 are disposed stepwise with respect to each other, The heat conductor 110 is inserted. The first and second diaphragms 141 and 142 of the first and second diaphragms 141 and 142 have a length sufficient to intersect the ends of the first and second diaphragms 141 and 142. The front center of the inner housing 140 passes through the first and second diaphragms 141 and 142, 110) constitute three layers. As a result, the heat transfer member 110 can maintain a tightly coupled structure between the first and second diaphragms 141 and 142, and the air in the second compartment space S2 can flow through the first compartment space S1 It is possible to effectively block the influx.

The inner housing 140 is formed on the inner side of the outer housing 160 and is separated from the first compartment space S1 by the inner housing 140 and the second compartment space S2 by the outer housing 160, Thereby forming a structure partitioned from each other. 3, the planar surface and the bottom surface of the inner housing 140 are spaced apart from the planar surface and the bottom surface of the outer housing 160, respectively. Therefore, the planar surface and the bottom surface of the inner housing 140, The bottom surface is exposed to the second compartment space S2 of the inner housing 140 as it is. The cool air introduced into the second compartment S2 from the outside is transferred to the first compartment S1 through the plane of the inner housing 140 in addition to the second heat discharger 130, The heat introduced into the compartment space S1 is transferred to the second compartment space S2 through the bottom surface of the inner housing 140 in addition to the first heat discharger 120. [

In this embodiment, only the flat surface and the bottom surface of the inner housing 140 are exposed in the first compartment space S1 of the outer housing 160. However, all the surfaces except the rear surface of the inner housing 140 are exposed in the first compartment space S1, (S1).

As a result, the inner housing 140 efficiently exchanges cold and hot air between the first and second compartment spaces S1 and S2, and minimizes the influence of heat, cold, and the like emitted from the outer housing 160 itself.

The heat exchanger 100 of the present embodiment includes a first circulation fan 150 for introducing air into the first compartment space S1 of the inner housing 140 to flow out through the first heat discharger 120, And a second circulation fan 170 for introducing air into the second compartment space S2 of the first heat exchanger 160 and flowing out the second heat exchanger 130 through the second heat exchanger 130. [

The first and second circulating fans 150 and 170 are a power source for introducing air into the housings 140 and 160 and then allowing the air to flow out after the heat exchange. The first circulation fan 150 formed in the inner housing 140 sucks the internal air of the electrical component E into the first compartment space S1 through the inlet 147 , And discharges the introduced air to the inside of the electrical product (E) through the outlet (148). Since the inlet 161 and the outlet 162 of the outer housing 160 are communicated with the outside, the second circulation fan 170 formed in the outer housing 160 is configured to discharge outside air through the inlet 161 to the second And sucked into the compartment S2 and discharges the introduced air to the outside through the outlet 162. [

In this process, the air introduced into the first compartment S1 passes through the first heat discharger 120 and transfers the heat to the first heat discharger 120. The cooled indoor air passes through the first heat discharger 120, And is discharged to the inside of the electric component E through the outlet port 148.

Meanwhile, the heat transferred to the first heat discharging body 120 is transferred to the second heat discharging body 130 through the heat transfer body 110, and the first heat discharging body 120 is cooled again.

The outside air introduced into the second compartment S2 passes through the second heat discharging body 130 and transfers the cold air to the second heat discharging body 130. The heated outside air passes through the second heat discharging body 130, And is discharged to the outside through the outlet 162 together.

As a result, the internal air of the electric component E is discharged to the outside while passing through the first heat discharging body 120, the heat discharging body 110, and the second heat discharging body 130 in sequence, Is discharged into the electric component (E) through the body (130), the heat conductor (110) and the first heat sink (120).

In this embodiment, the first heat discharging body 120 is located at the lower end and the second heat discharging body 130 is located at the upper end. This is because when the fluid such as alcohol and water filled in the heat conducting body 110 is vaporized by heating And descends when it is liquefied by cooling again. However, the positions of the first and second heat sinks 120 and 130 are not limited to those described above, and various arrangements may be made within the scope of the following embodiments.
