In this case, when the relay duct 113 is omitted, the relay duct connector 165 may also be omitted.

The fan connector 164 includes a fastening hole (164a of FIG. 12) to be coupled by the blower fan 170 and the fastener. Of course, in addition to the fastening method by the fastener may also be coupled by other known coupling method.

11 and 12 are enlarged views illustrating main parts for explaining the first partition plate 163.

The first partition plate 163 may be provided in a cross shape to cross at an angle of 90 degrees. In some cases, the crossing angle may not be 90 degrees. Accordingly, the air discharged in the air discharge direction A is divided into four places and discharged through the air discharge port 112.

The first partition plate 163 may be coupled to the converging portion 162 by welding or contact.

In addition, the shape of the first partition plate 163 is merely an example and may be variously changed. For example, the first partition plate 163 may be provided in one shape to divide the air discharged through the air outlet 112 into two.

Here, the experimental data on the effect of the first compartment plate 163 on the discharge speed of the air discharged through the air outlet 112 is shown in Table 1 below. In more detail, when the first compartment plate 163 is not provided in the temperature control device 1, when the first-shaped first compartment plate 163 is installed, the cross-shaped first compartment is provided. When the plate 163 was installed, the air discharge rate at the air outlet 112 was measured in each case.

TABLE 1

CASE  No first compartment  One-shaped first division edition Dozen
First compartment maximum
Discharge speed 9.16 m / sec 11.82 m / sec 12.56 m / sec

That is, when the straight first partition plate 163 is installed, the discharge speed is improved by about 30% compared with the case where the first partition plate is not provided, and when the cross first partition plate 163 is installed, the first compartment is installed. It can be seen that the discharge speed is improved by more than 37% compared to the case without the plate.

In addition, the cross-shaped first partition plate 163 was found to be somewhat better than the straight first partition plate 163.

The discharge speed at the air outlet 112 is an important factor for indicating the performance of the temperature control device 1 in that the temperature of the optical tracking device R, which is the temperature control target, can be maintained within a predetermined temperature range within a short time. factor).

Here, when the exhaust duct 160 without the first compartment plate 163 is installed, the air discharge rate measured at the air outlet 112 was also measured to be 9.16 m / sec. This is about 60% more than the discharge speed when the exhaust duct 160 is not provided. When the first partition plate 163 is installed inside the exhaust duct 160, a greater discharge speed can be obtained. have.

Meanwhile, as illustrated in FIG. 5, the heat exchange unit 100 may further include an intake duct 180 for guiding the air introduced from the air inlet 111 to the evaporator 130.

Here, the air inlet 112 may be provided with a relay duct 117 for connecting the intake duct 180 and the first connection duct (D1 of FIG. 1). In some cases, for example, when the intake duct 180 and the first connection duct D1 of FIG. 1 are directly connected, the relay duct 117 may be omitted.

The intake duct 180 may be provided such that a cross-sectional area of the intake duct 180 increases in at least a portion of the air inlet 111 from the air inlet 111 toward the evaporator 130.

When the relay duct 117 is present, the intake duct 180 is interposed between the relay duct 117 and the evaporator 130 as shown in FIG. 5, and the relay duct 117 is provided. If not, the intake duct 180 may extend from the evaporator 130 to the air inlet 111.

The intake duct 160 may be provided such that its cross-sectional area is gradually increased along the air inflow direction B toward the evaporator 130 from the air inlet 111.

Here, the intake duct 180 may be provided so that the cross-sectional area is gradually increased over the entire period from the air inlet 111 to the evaporator 130, as shown in FIG. It may be provided so that the cross-sectional area is gradually increased only in a section from the 117 to the evaporator 130.

As shown in FIGS. 6 to 8, the intake duct 180 may include a relay duct connection part 182 connected to the relay duct 117; An expansion unit 186 extending the inflow air introduced through the air inlet 111 along the air inlet direction B; It includes an evaporator connecting portion 184 and the relay duct connecting portion 182 and the neck portion 185 connecting the expansion portion 186 is connected to the evaporator 130.

If necessary, the relay duct connecting portion 182 and the neck portion 185 may be omitted.

The relay duct connector 182 includes a plurality of fastening holes 182a to be coupled to the relay duct 117 by fasteners.

The evaporator connecting portion 184 includes a plurality of fastening holes 184a to be coupled to the chassis 131 of the evaporator 130 by a fastener.

6 and 7, the cross-sectional area of the most upstream side along the air inflow direction B is (GXJ), while the cross-sectional area of the downstream side is the most (LXJ) as shown in FIGS. The cross-sectional area on the downstream side is larger.

Here, the width J of the expansion part 186 of the intake duct 180 corresponds to the thickness (K of FIG. 9A) of the evaporation part 130. The length L of the expansion part 186 corresponds to the length of the portion L on which the evaporation pins 133 of the evaporation part 130 are arranged.

The intake duct 180 may further include at least one second partition plate 181, 183 disposed in the intake duct 18 to distribute the inflow air along the width direction of the evaporator 130. have.

The second partition plates 181 and 183 may be disposed in the extension part 186.

The second partition plates 181 and 183 may be coupled to the extension part 186 by welding or adhesion.

The second partition plates 181 and 183 may be provided in plural as shown in the drawing. In some cases, one may be provided or three or more may be provided.

When two second partition plates 181 and 183 are provided, the angle between the extension lines of the second partition plates 181 and 183 may be 35 degrees.

The second partition plates 181 and 183 may allow the inflow air to pass through the evaporator 130 by being substantially evenly distributed along the width direction of the evaporator 130. Accordingly, heat exchange may be performed between the inlet air and the entire region of the evaporation pin 133 of the evaporator 130.

In the case of employing the intake duct 180, the cooling ability may be improved by about 20% under the same conditions as compared with the intake duct 180. When the intake duct 180 is absent, the air introduced through the air inlet 111 is concentrated through only one region of the evaporator 130, so that heat exchange is localized only in a partial section along the evaporator 130. Concentration decreases during heat exchange.

In addition, since the width J of the intake duct 180 corresponds to the thickness of the evaporator 130, the inlet air introduced through the air inlet 111 does not leak to the outside, but directly to the evaporator 130. Is provided.

In addition, since the direction of the evaporation pin 133 of the evaporator 130 coincides with the air inflow direction B, the inlet air guided through the intake duct 180 is formed between the gaps between the evaporation pins 133. Through the heat exchange efficiency can be further increased.

In addition, the heat exchange unit 100, as shown in Figure 4, 5, 9A and 9B, and a support frame 114 for supporting the evaporator 130; A condensate receiver 190 may be further included to temporarily store condensed water condensed on the surface of the evaporator 130. 9A is a schematic cross-sectional view taken along the line a-a of FIG. 5.

The support frame 114 has a first opening (114a) for passing the condensed water and the air cooled through the evaporator 130 passes; It includes a second opening (114b) formed so that the cold air passing through the first opening (114a) flows in the direction of the blowing fan (170).

That is, the inlet air is cooled by heat exchange with the evaporator 130 while passing through the evaporator 130, and the cold air passes through the support frame 114 through the first opening 114a to receive the condensate. Flows into 190.

Next, the introduced cold air passes through the internal space S formed by the support frame 114 and the condensate receiver 190, that is, moves along the N direction of FIG. 9A, and then returns to the second opening. It is exited in the direction of the blowing fan 170 through 114b.

Accordingly, the cool air passing through the second opening 114b by the blowing fan 170 is blown through the air outlet 112 to cool the electro-optical tracking device R.

On the other hand, the condensate receiver 190 includes a condensate through-hole 195 for discharging the condensate. The condensate receiver 190 may be provided such that the location of the condensate through hole 195 is the lowest position such that the condensate stored therein may be collected around the condensate through hole 195.

Here, the condensate through-hole 195 may be formed in the protrusion 193 protruding from the lower surface of the condensate receiver 190, as shown in Figure 9b.

The protrusion 193 is connected to a condensate outlet (not shown) formed in the unit body 110.

As shown in FIG. 10, the condensate through hole 195 communicates with the condensate pipe 15 provided on the bottom surface of the apparatus body 10.

Here, the temperature control device 1, as shown in Figure 3 and 10, the condensate pipe 15; A condensate valve 80 for opening and closing the condensate pipe 15 according to an external signal; The control knob 90 may further include a control knob 90 capable of manually operating the condensed water outlet 93 for finally discharging the condensed water that has passed through the condensed water valve 80 to the outside.

The condensate valve 80 may include an electromagnetic valve.

The condensate outlet 93 may be provided with a condensate tube 95 for guiding the condensate to the ground.

When the temperature control device 1 is transported, if the condensed water is discharged through the condensed water outlet 93, it may cause inconvenience in transportation. Can be prevented.

In addition, as shown in FIG. 2, the temperature control device 1 further includes the controller 70 accommodated in the apparatus body 10 to control the first half of the temperature control device 1.

The control unit 70 transmits a primary open signal to the condensate valve 80 through the condensate valve control signal transmission line 83 to open the condensate pipe 15 when the blower fan 170 is turned off. do. That is, when the blower fan 170 is turned off, it means that the temperature control device 1 is no longer used. In this case, the condensate valve 80 may discharge the condensate stored in the condensate receiver 190 to the outside of the apparatus. The primary open signal is transmitted as a control signal.

The condensate valve 80 opens the condensate pipe 15 when receiving the primary open signal. Accordingly, the condensed water stored in the condensate receiver 90 in the heat exchange unit 100 is discharged to the outside of the apparatus. The condensate valve 80 opens the condensate pipe 15 and transmits a response signal thereto to the controller 70.

The control unit 70 transmits a secondary open signal to the condensate valve 80 when the response signal to the primary open signal is not received within a predetermined time after the primary open signal is transmitted.

Here, the second open signal is generated based on a pressure difference between an internal pressure inside the heat exchange unit 100 and an external pressure outside the heat exchange unit.

In order to generate the second open signal, as shown in FIG. 4, the heat exchange unit 100 senses an internal pressure inside the unit body 110 and an external pressure of the unit body 110 as a result. It may further include a pressure sensor 140 for transmitting to the control unit 70.

Even when the blowing fan 170 is OFF, the pressure inside the heat exchange unit 100 is lower than the external pressure by the operation of the blowing fan 170 until a predetermined time. Therefore, by using the control unit 70, if the response signal for the primary open signal is not received within a predetermined time after the primary open signal is transmitted, the internal pressure of the measurement result by the pressure sensor 140 is increased. When it is judged to be lower than the external pressure, the secondary open signal is transmitted back to the condensate valve 80 as a control signal.

Accordingly, even if there is an error in the transmission of the primary open signal, the discharge of the condensate can be completed more reliably by retransmitting the secondary open signal.

On the other hand, the heat exchange unit 100, as shown in Figure 4, 5 and 8, the outlet temperature sensor 153 for detecting the air temperature, that is, the outlet side temperature discharged through the air outlet 112 And a heater 155 for heating and an inlet temperature sensor 155 installed in the intake duct 180 to sense a temperature of the inlet air passing through the intake duct 180. have.

When the temperature measured by the inlet temperature sensor 155 exceeds the first predetermined temperature, the controller 70 drives the compression unit 10 and the blower fan 170 for cooling operation.

On the contrary, when the measured temperature of the inlet temperature sensor 155 is less than the second predetermined temperature, the controller 70 operates the heater 155 for heating operation.
